This morning BT Broadband (Fibre Optic BT Infinity) is having problems connecting to many websites, including Twitter and BT’s own help pages. This appears to be the case across their entire network and is rather infuriating, to put things mildly. Thankfully there is a fix you can apply yourself – here’s the step by step instructions on how I got my BT broadband back up and running.
1) Get a router
BT broadband comes with two devices, a white one which converts the fibre signal into something your computer can understand and a black one called the BT Home Hub. The BT Home Hub doesn’t let you set your own DNS servers and therefore can not be used to fix the problem. You’ll need to use a different router. Thankfully I have an Apple Time Capsule to hand to use as a router, but if you don’t have one take a trip to your local electronics/computer shop and pick one up – Currys/PCWorld for instance have one for £16.99. You’ll need to unplug the cable that goes from the white modem to the BT Home Hub from the BT Home Hub and plug it into the new router.
2) Set up the Router
Follow the instructions for setting up the router. When prompted with how you want to connect to the internet you need to choose PPPoE using the username [email protected] and the password BT. After setting up the router confirm the internet is working. Twitter and other down sites still won’t work as you haven’t configured the DNS yet.
3) Configure the DNS
Follow the router manufacturers instructions on how to configure DNS. There’s many DNS services out there but the one I got to work was Google Public DNS. For some reason OpenDNS wasn’t playing ball, but if it was it would have been my preferred option. To connect to Google Public DNS simply input 126.96.36.199 and 188.8.131.52 as the DNS servers then accept. After your router restarts you should have full internet access including on the sites that weren’t previously working.
Remember to set up passwords on your new wireless network AND for your router configuration. You don’t want to let random people have unsecured access to either your network or your settings, and failing to set up these passwords will allow that.
You’ll also need to reconnect all your devices to the new network with your new password.


Cross-window messaging API is supported by all modern browsers including IE8. It allows windows/frames from multiple domains to communicate with each other.
To send a message to another window referenced by
win, the postMessage method is used.
postMessage(data, targetDomain), where:
- The message. Accordin to the specification, it could be any object. But as of now, only strings are supported in major browsers.
- Limit receiving iframe by given domain. Can contain ‘*’ which doesn’t put any restrictions.
Usually, the domain of iframe is known, so it is recommended to pass it as the
targetDomain argument for better security.
Let’s see how it works from the sending side.
By pressing the button, you send the message to iframe on another domain. The browser controls that the domain must be

The special propertys of a message event are:
- The first argument of
- The source domain
- The reference to sending window. It is possible to respond by calling
event.source.postMessage('..response message..', event.origin).
The messages are passed using internal browser API. So there is no network communication at all.
In IE8, it is possible to use
win.postMessage for iframes only, not for other tabs/windows. That’s the bug of implementation. Other browsers don’t suffer from that.
postMessage API allows to communicate between windows in a safe, cross-browser way.
Works in all madern major browsers including Chrome/Safari, Firefox, Opera and IE8.
IE8 doesn’t allow to

Smartphones have been arguably the most revolutionary gadgets of modern technology. Most decent smartphones can do everything that a PC can do and more – and they fit easily in your pocket.
Smartphones have come a long way since they were first developed. They have come from bulky gadgets that were mostly for a show to slim and sleek devices that can monitor your health – and more. They are still developing, and the future smartphone will be better in virtually every aspect.
Are you curious about what the future smartphone will have to offer? Here is an overview of eight features that will improve drastically.
It is embarrassing that smartphone users across the world still struggle with unreliable network connections. Fortunately, you can avoid that using this guide to cell phone boosters by weBoost. However, this is expected to change soon with the introduction of the 5G network.
5G technology is expected to support revolutionary new advances in technology. One of its greatest benefits will be a strong and reliable network connection and fast internet speeds. This means that your video and voice calls will be flawless, making for reliable communication. You will also enjoy smooth streaming and ultra-fast download speeds.
5G technology is already at the world’s doorstep. However, it has been the cause of global controversy and technology wars between the U.S. and China. Additionally, some entities are concerned that rolling out 5G technology worldwide may have adverse effects on the environment.
However, researchers are working to find solutions to these limitations. More importantly, the technology is already in use in some parts of the world.
It is also worth noting that network providers and smartphone manufacturers are planning to phase out SIM cards. SIM cards will be replaced with electronic versions of programmable SIM chips that will be built into the handset. This will also have a wide range of benefits, including switching network carriers at will when travelling abroad to avoid high international roaming costs.
The screen is the most prominent feature on the smartphone. A smartphone’s screens most important factors at the moment are its size and resolution/display. However, smartphone screens of the future are pushing the limits when it comes to functionality.
Smartphone screens will be pressure-sensitive, for starters. This feature will make it possible for your smartphone’s screen to sense how much pressure you apply.
The idea is that varying levels of pressure will unlock different features, making the screen more functional – especially for gamers. This feature has already been rolled out by Apple on its smartwatches, dubbed the Force Touch.
The future smartphone screens will also feature photonic crystal displays. This new feature is expected to improve smartphones’ overall display, especially when you are out in the sun.
The current smartphone screens become less visible when surrounded by bright natural light. Photonic crystal displays will automatically detect the surrounding ambient light and adjust the display to ensure optimal visibility.
These are not the only gains made in screen development. For example, Samsung has a new foldable screen. However, these features will be dismal compared to what the future has to offer.
Smartphones have a few shortcomings, and low-capacity batteries are at the top of the list. These devices are only useful when they are running.
Unfortunately, most smartphone batteries can only store enough power to last an average of eight hours, which is not usually enough to get most users through the day. To this end, many smartphone owners usually travel around with their chargers and power-banks to keep their smartphones on.
Smartphone batteries have been improving gradually, and new batteries can store more power for longer. However, they still pale compared to future smartphone batteries, which are expected to charge much quicker and last much longer.
StoreDot, an Israeli tech company, is working on a nano-tech battery. This battery has been inspired by the discovery that peptide molecules have an exceptionally high capacitance and show great potential for storing power.
StoreDot’s nano-tech battery has already passed the first phases of development. The battery was charged from zero to 100% in less than a minute during the initial test in 2015. However, its power retention capacity was lower than the standard lithium-ion battery. The company is currently working on improving its capacitance before releasing it to the public.
The camera is one of the most popular features on a smartphone. To this end, many smartphone users snap dozens of photos and record videos using their smartphone cameras daily.
Consequently, smartphone developers have been working on improving the quality of their cameras. For example, Apple and Samsung have introduced a new camera design featuring three individual cameras designed to work simultaneously. Additionally, new versions of virtually every smartphone model are featuring smaller cameras with higher megapixel capacities.
Future smartphone cameras will be smarter and capable of identifying individual objects. This will make cameras capable of spotting targets within a frame, making them functional for purposes more important than snapping photos.
Qualcomm is already working on a camera that can identify different objects by referencing a vast database of these objects’ shapes, colors, texture, and other characteristics. Google is also working on algorithms that will enable its search engine to make search queries based on images.
The voice command feature on smartphones is already impressive. In fact, many people interact with their smartphones, mostly via voice command. It is simple: just issue a command to Siri, Alexa, Google Assistant, or your chosen voice command feature and wait for an answer!
However, there is only so much that Siri and Alexa can do. For example, these voice assistants often get commands wrong, and it is frustrating trying to articulate what you want. To this end, the current voice command assistants will seem dismal compared to future voice assistants.
Smartphone developers, led by Apple and Google, are working on new voice command algorithms that will be integrated with Artificial Intelligence (AI). This will solve the problem of confusion and miscommunication when issuing commands.
More importantly, it will make these voice assistants intuitive, making them capable of anticipating your thoughts and actions. It will be like having a human assistant in your pocket.
Smartphones currently don’t feature physical keyboards, which were phased out with the first-generation mobile phones. However, future smartphones will feature a revolutionary keyboard – one that will be made of liquid!
The future smartphone screens will also have buttons – liquid buttons. Developers are using micro-fluid technology to form button-shaped controls beneath the smartphone’s screen. This technology is already under development by Tactus Technology, and it has been touted as something out of an advanced alien civilization.
Your smartphone is a treasure trove of your personal information, including intimate details that you wouldn’t want anyone else to know. Many people try to secure their smartphones using passwords and other cybersecurity features.
However, hackers are becoming smarter and developing new ways around these security measures. To this end, smartphone manufacturers are focusing more on biometric forms of cybersecurity, which are more secure.

Optical Fiber Amplifier: An optical fiber amplifier is a fiber optic device used to amplify optical signals directly without conversion into electrical signals. Optical fiber transmission has revolutionized networking and communication systems.
Multiple communication devices, like optical transmitters and receivers, are used in optical fiber. Optical fiber is used as a medium for telecommunication and computer networking because it is flexible and can be bundled as cables. It is especially advantageous for long-distance communications, because infrared light propagates through the fiber with much lower attenuation compared to electrical cables.
This allows long distances to be spanned with few repeaters. In this paper, we present coherent optical single carrier transmission (COSC) using overlap frequency domain equalization (OFDE) for the chromatic dispersion (CD) compensation.
Residual inter-symbol interference is suppressed by time domain equalization with small tap size. In single polarization transmission, Gb/s COSC transmission with OFDE is demonstrated over. Attenuation of fiber mainly determines the maximum transmission distance of optical communication systems without amplifiers or repeaters, as well as the maximum output power from the light source and the minimum receiver sensitivity.
The attenuation is basically caused by absorption, scattering, and radiation of optical power. Jeff Hecht, in Handbook of Fiber Optic Data Communication (Fourth Edition), Now coherent transmission is back, powering commercial systems transmitting Gb/s line rates on a single optical channel.
Developers gave coherent transmission a new chance when they needed to squeeze Gb/s data streams into the 50 GHz bands assigned to WDM channels. Researchers have demonstrated a kilometer fibre-optical transmission link using ultra low-noise, phase-sensitive optical amplifiers.

In situations wherein the primary issue is loss, optical amplifiers can indeed be used to amplify the signals without conversion into the electrical domain. Such Optical Amplifiers have truly revolutionized long-distance fiber optic communications.
The purpose of an optical amplifier is to restore the signal power level, reduced due to losses during propagation, without. The use of optical fibers for power transmission has been investigated intensely.
An optically powered device combined with optical data transfer offers several advantages compared to systems using electrical connections. Optical transmission systems consist of a light source, a transmission medium and a light receiver.

The reach improvement shown is times that which is possible when using conventional erbium-doped fibre amplifiers. In this tutorial, we will discuss the maximum distance that a fiber cable can transmit without an amplifier or repeater.
This distance is limited by the fiber’s attenuation (loss) and dispersion (pulse widening). In practice, fiber link distance can be extended by.
Transmission distance has become one of the biggest problems in the super fast optical communication. On one hand, with the expansion of the fiber optic network, distances for the optical links span meters to hundreds of meters and even kilometers. On the other hand, optical signal becomes weak over long distance.

The wifi router is, increasingly, one of the most important appliances in the modern home. You probably just don’t know it yet. Think about it. How do you connect to the internet at home? How do you watch Netflix or Hulu? Do your children game online? Are they doing their homework out of books, or are assignments online? How do you pay your bills? My guess is that the vast majority of the things I just mentioned are all being funneled through your home’s wifi router and according to statistics you’re probably using aging technology that is dragging you down, but we’re going to present you with some options to fix that, right now.
First things first, the speed of your internet connection all begins with the bandwidth (the overall capacity) your internet provider is delivering to your home. Some will be faster than others. For example, AT&T Uverse is still delivering internet to the home over a mix of fiber and copper wire (copper wire is what your phone lines have been using for up to 50 years in some places) so their speeds tend to top out lower (up to 18Mbps) than Time Warner who is delivering internet via existing cable infrastructure and, in some places, fiber (up to 300Mbps). This is the reason that often times people with the former tend to have issues with streaming videos stalling when they try to play them. This is called “buffering.” Once you’ve determined which kind of technology your internet service provider (ISP) is using, the next thing to look at is your modem. That’s the piece of technology that connects the internet from the provider to your home. It’s that little box that we used to have to plug an ethernet cable directly into our computer to get internet access. For those using some services, the modem is actually a gateway device that brings internet, TV and television into your home. For those on traditional cable services like Comcast, the modem is separate from the television connection which comes into the home via something called coaxial cable.
Now your ISP may have 300Mbps service but an older modem (often the one you lease from Time Warner won’t be the fastest one available) will throttle your maximum potential speeds as it may only be rated for 150Mbps or less. Let’s say you have the fastest package that Time Warner offers and a future proof modem, that last component in the chain is your wifi router. If you’re still using an old 802.11b router then you’re not getting anywhere near the speeds you should be getting and if you have multiple devices all accessing the internet, you’re truly being hamstrung. Even if you’ve purchased a new”ish” router like one using the wireless G standard or 802.11n, you’re still not getting your money’s worth if you’re paying for faster speeds from your service provider.
All of those older routers are what’s called single user, multiple input, multiple output devices, or SU-MIMO routers. How they work is that each device on your network is given a priority and the router sends a signal out to each one, one at a time. This is a very simplified explanation but that’s essentially how it works. So, if one device is hogging the majority of your capacity because it is doing an intensive task like streaming HD video or online gaming, the rest of the devices accessing the network will experience slower speeds.
MU-MIMO, or Multiple User- Multiple Input Multiple Output wifi routers are the latest technology that every family with multiple devices on their network should know about and that’s what we’re actually reviewing today. Linksys Max-Stream AC2600 MU-MIMO Gigabit Ethernet EA8500 is among the first to put out a wifi router for home use with this technology active right out of the box and let me tell you, it is FAST!
At any given time I have 10 to 15 devices connected to my home network via wifi and ethernet. Prior to this review I was using one of Linksys’ competitor’s top routers, affectionately known as the Nighthawk. It was one of the fastest dual-band AC wifi routers on the market at the time I purchased it, and everything in my home was getting sufficient enough speeds; though from time-to-time my sons experienced lag on their XboxOne during online gaming. What is the primary difference between the EA8500 and the Nighthawk? MU-MIMO technology sends three simultaneous signals to three devices at a time as opposed to one at a time. To keep it simple, it’s like having three different internet connections sending signal out to the devices in your home. Theoretically these routers are supposed to support four simultaneous streams but currently they cap out at three. I have to say that I didn’t expect what I was going to see from my devices that didn’t have compatible MU-MIMO wireless chips inside them but I saw speed increases on the 2.4gHz band of 100% in many cases. Where I was getting 24mbps download speeds on the Nighthawk, I was seeing 48Mbps or better from the EA8500 but that’s not the most exciting part!
The Linksys MU-MIMO router was able to deliver those speeds on its 2.4gHz network to multiple devices on my network without degradation in speed no matter if it was the XboxOne receiving wireless signal, gaming online, or my Google Chromecast streaming Netflix in the back room, or my iPad streaming YouTube videos. All were able to go about their usual tasks without slowing due to how this new router handles multiple signals. And the 5gHz band has a stronger broadcast signal than my previous router. In the back of my apartment, where I do a lot of my reading, I saw a 3-8 dB gain and faster speeds. The signal before was weak enough that in the back of the apartment I often would stay on the slower 2.4gHz connection since it had better reach. Not anymore!
As a father, the other aspect of this router that I greatly appreciated is Linksys’ SmartWIFI app, available for both Android and iOS, and accessible from any web browser. The app and web access component all allow you to access and control your wifi network from anywhere you have an internet connection. What that means for your as a parent is that during those summer months when the children are home from school you’ll have complete control over whether or not each individual device in your home has access to the internet. If you want the children to do chores before getting online, simply cut access to their individual devices from the app, then turn access back on when ready. The app is pretty robust and does much more than that. You can change passwords, turn guest access on or off, access network storage settings, almost all of the settings you can access from the admin login to your router itself, can be accessed through the SmartWIFI app. From the app, you can even access port forwarding options, which you may need for certain PC gaming and console gaming activities. If you truly want to get granular with the settings though, you’ll want to log in directly to the router. SmartWIFI is a simplified interface for those who are not network savvy, but provides enough access and tools to set things up quite well.
The EA8500 has USB ports to attach external storage for sharing and/or streaming music, or backing up files. It’s also a great option to have for moving files between computers on the network. In my testing, the speeds at which files were moved between laptops was noticeably faster than my previous router. Matter of fact, it actually blew it out of the water. If you’re using the router instead of a NAS (network attached storage) device, then you won’t be disappointed with the performance of the Max-Stream when it comes to connecting a hard drive, solid state drive or flash drive to your home network system.
The Wrap Up
The Linksys EA8500 is based on something called AC2600, and while there are other routers on the market which utilize this version of the AC standard, they’re generally operating on SU-MIMO technology. Because of that, they’re going to be inherently “slower” than any router with the newer MU-MIMO technology baked in. At the end of the day, is this router worthy of being your next purchase? There are a couple things that go into that decision. First, all of your devices currently don’t use wireless MU-MIMO chipsets inside of them so the only thing in your home that would have it is the router itself. In order to get the maximum benefit, you’ll need both the router and your devices to have the same technology inside. Since Linksys has partnered with Qualcomm for its chipsets and Qualcomm also makes most of the chipsets inside your mobile devices, this should happen in relatively short order, though “short” could be many months away. The other item to consider is that there are “tri-band” routers on the market which may be faster than the EA8500 but you will pay more for them and they’re still only SU-MIMO technology. Being that there are other routers which will come to market using MU-MIMO and this is one of the first to feature it out of the box, if you purchase now, you will be an early adopter. Here are my thoughts:
- If you and your spouse or S.O. have smartphones and a tablet and at least one computer in the home and one streaming appliance dedicated to running Netflix, Hulu or some other service you can live without it but it will speed up your browsing and widen your signal coverage throughout your home or apartment.
- If you have the disposable income are generally an early adopter and were looking to upgrade, do it. If you’re a family of three or four and you have/use all of the devices outlined in the previous point, including a child with a device or two, then I can absolutely recommend the EA8500.
- If you’re like me and have a family of five, with all of the above, which includes three children with their own laptops, gaming devices and phones and you’re looking to upgrade your wireless network or didn’t even know that you should and upon reading this have decided to do so, then this should be atop your shortlist. Period.
- Additionally, when you consider all of the things that will be connecting to your wifi router in the coming months and years, you’re going to need a device that can handle all of that connectivity. The Internet of Things is upon us and your HUE lights, Nest Thermostats, Piper Home Gateways, smart refrigerators and washer/dryers will all be vying for bandwidth and you’re going to need something that can handle the stampede, corral it and keep it in order without slowing you down. MU-MIMO and future iterations of it should help you do just that! If you tend to be more of a “wait and see” tech buyer, there will be more MU-MIMO products to come which will give you the opportunity to compare performance and value among MU-MIMO enabled routers.
Specs, Setup and Speedtests
Routers really have become very user friendly in the last few years. Setup is often as easy as connecting an ethernet cable from the modem, or gateway provided by your ISP, to the EA8500 and waiting for the LINKSYS light on top of the router to go from pulsating to a solid light. The solid light means that you have a steady connection. Next, you’ll jump on any computer with wifi turned on and look for the wireless network names printed in your Quick Start guide, use the wireless password printed there to connect. Once connected, point your browser to linksyssmartwifi.com and configure your router. First thing you should do is change the router password. After you’ve done that, change the wireless network names and passwords. Please use strong passwords! Don’t use, iloveyou, or 0000, or your birthday or dog’s name. You do your banking online, let’s not make it easy for people to intercept your network traffic. You can play around with the settings but one I recommend you adjust, especially if you have young ones who game or watch streaming videos is to set your own streaming video device(s) and laptop(s) as the traffic priority. You can only set three devices as the top priority but you can go into the router itself (not the SmartWIFI app) and set priorities for apps and services as well. If you really want to lock things down, you can also turn off SSID broadcast so no one can see your network name.

This catalog lists the most common configurations for each cable type. If necessary, IW can modify existing designs or design a custom connector to meet your specific requirements. Our standard connectors meet the environmental specifications of MIL-PRF-39012. See table on page 34 for maximum operating frequency.
Determination of Phase Change Over Temperature
The following example illustrates how to calculate the change in phase (and the tracking error) of cable assemblies over a specific temperature range. In this example, the cable is IW 2801, and the temperature range is -40˚C to +80˚C.
* determined by the charts above ** tracking error of two or more assemblies of the same type
Phase Change with Flexing
Phase change when flexing will be slightly different depending on the particular cable. Larger cables have more dielectric and greater internal forces, thus phase change will be greater for cables with larger diameters. When wrapped 360˚ around a 4 inch diameter mandrel, the phase change will be:
+0.30˚ • f – for cables 480, 280, 230, 180 and 170
+0.20˚ • f – for cables 157, 150 and 140

Frequency = 10 GHz f Assembly length = 72 in L Start temp = 20˚C T Dielectric const = 1.4 e Change in PPM = -500* PPM PPM tracking error = ±100 PPM tracking Electrical length = TBD F Change in phase = TBD DF Tracking error = TBD** F tracking
Phase Match & Time Delay
For applications where phase or electrical length is a critical performance parameter, IW can provide matched assembly sets, tested to customer specifications, typically up to 40 GHz, with both Low Loss Phase Stable and Re-Flex™ cable types. Relative phase matching is a common requirement achieved with multiple assembly sets. Typical phase matching tolerances are shown in Table 1 below.
Tighter tolerances may be achievable; IW engineers review all matching requirements on a case by case basis. In addition, IW also provides time delay matched assemblies with tolerances in the order of 2pS being achievable with both Low Loss and Re-Flex™ cable types, and individual assemblies can also be supplied trimmed to a specific electrical length. All matched assemblies are tested 100% for insertion loss and VSWR performance parameters in addition to phase.
Engineering Design Data
TUF-FLEX™ Cable Performance
The same cable was tested to measure performance with successively tighter bend radii. The serving used to create the armor not only provides excellent crush resistance, but maintains the concentricity of the cable as it is flexed through a radius, enabling RF performance to be maintained.
The following contains a list of precautions and procedures that should be taken when handling or installing Insulated Wire cable assemblies. They should be used as guidelines and followed whenever possible. By doing this you can ensure a long assembly life which requires virtually no maintenance.
Handle cable with care:
IW cable assemblies are designed to operate at the highest electrical performance level. High performance cables such as these require special handling procedures to ensure optimum electrical performance. Many of these handling procedures are outlined in detail, however taking just a few basic preventative measures during handling can significantly extend the life of the assembly. You should always take care to prevent anything from being placed on an assembly. This could result in internal damage caused by compression. Also, prevent the cable from bending below it’s minimum bend radius as this will cause the cable to kink, which results in internal damage and subsequent degradation in RF performance.
Limit bend radius whenever possible:
Although IW cable assemblies can accommodate a very small bend radius, it is recommended to use the widest possible radius to fit the application. This will help to keep mechanical stresses low through the bend and prolong the life of the assembly.
Avoid torquing down connector ends until both connectors are mated in position:
It is important to first hand tighten both connectors into position before any torque is applied. If a connector is torqued down before the assembly is routed into position, excessive torsion could be applied at the torqued connector’s termination during the routing. These torsion forces could cause the dielectric to change its mechanical position at the connector termination. This could ultimately lead to an electrical failure.
Avoid twisting assembly to orient connectors:
When installing assemblies with right angle connectors, do not twist the cable or connectors to orient with the mating connectors. Twisting the assembly could result in mechanically changing the dielectric position at the termination and ultimately lead to an electrical failure. Assemblies should be purchased with a specific connector offset angle to match the proper mating connector. If an offset angle needs to be changed during assembly installation, proper adjustment procedures can be obtained by calling IW’s Technical Support.
Avoid bending the assembly at the connector termination:
A cable assembly should never be bent at the back of the connector. Applying a bend prematurely at the end of an assembly and allowing the bend to encompass the connector could lead to the build up of excessive cable forces against the connector and through the bend area. The applied forces will cause the cable to kink. Electrical degradation and possible failure may result.
Avoid pulling an assembly through channeling by the connector end:
Never pull an assembly by its connector when routing it through a structure, channeling or building. Doing this could mechanically damage the connector termination. The assembly should always be pulled by the cable itself. Furthermore, the installation should be assisted by pushing the assembly through the channeling while the cable is pulled. Additionally, it is less stressful to the assembly if it is installed in phases (through individual sections) rather than a single run across the entire routing length.
Never allow an assembly to support its own weight when routed in a vertical installation:
Never allow an assembly to hang freely by its own weight. Clamp down the cable at equal intervals along its length. Cable hangers can be used when it is not possible to clamp down the assembly in a vertical installation provided the assembly has been reinforced for such an installation. Using multiple hangers whenever possible is also recommended to help evenly distribute the assembly’s weight along the run.
Avoid the use of cable ties:
Most high performance cables use an air filled dielectric core. This makes the cable very soft. Therefore any compressive load applied to the cable has the potential of collapsing the dielectric core within the cable. Cable ties and tie wraps are not recommended for this reason. They offer virtually no load distribution and consequently focus very high compressive forces through the tied down area. A concentrated force such as this almost always deforms the cable and significantly degrades assembly performance. For best holding results with minimal clamping forces, IW recommends rubberized clamps. Be sure to select a clamp that will apply a minimum amount of compression force while still offering the desired holding strength. Selecting a clamp that it too small can do as much damage to an assembly as a cable tie.
Avoid subjecting the connector ends to cable axial loads:
Cable assembly life can be increased by clamping down the cable a few inches from the connector ends in applications where the cable will be moving (such as a moving antenna) or where a high vibration condition exists. Clamping the cable down at the cable ends reduces mechanical loads applied to the connector when the cable is moved.
Always wrap connectors in weather proofing when installing outside:
All cable connections that will be subjected to rain and snow should be wrapped in a weather proofing material. A self fusing silicone tape is recommend to create a weather tight seal over the connection. If weather precautions are not taken, water will eventually work its way into the connector assembly causing high insertion losses.
Always provide adequate drip loops:
Always allow for a drip loop in outside applications to prevent water from flowing down the cable and onto the connector. Over time the water could work its way into the connector assembly causing high insertion losses.
Take extra care on short assemblies:
- Always bend assemblies around mandrels whenever possible.
- The use of mandrels or wheels will help to evenly distribute bending loads applied to the cable. This is the preferred method for bending cables.
- Take caution when bending cables by hand.
- Sometimes bending a cable by hand is the only option. In this case the following method should be used:
- Start at bending point keeping hands close together.
- Bend the cable a little at a time working in an outward direction along the bend.
- Return to the center point of the bend and work in an outward direction making the bend a little tighter.
- Continue to return to the center of the bend, and working outward until the desired bend is reached.
Take caution bending cables under 12” in length.
An assembly that is 12” in length and smaller can be very rigid depending on the cable type. The cable becomes rigid because its inner and outer conductors are fully (mechanically) terminated to the cable connectors. The cable is terminated this way to yield maximum electrical performance. Unfortunately, it minimizes the bending characteristics of the assembly because the cable is too short to accommodate the total material volume displacement needed for a typical bend. Often, the minimum bend radius can not be achieved without damaging the assembly. Therefore, short cables should only be used in applications where slight jogging bends will be used. A longer assembly that uses a service loop should be considered as a replacement for a short cable in situation where a tight or sharp bend is needed.
Phase Stable Cable
IW is pleased to announce that it has developed a new line of coaxial cables and assemblies which has improved the performance characteristics for all types of microwave applications. This new line of cable and assemblies yields smaller diameters, lighter weights, lower insertion loss, and enhanced electrical stability versus temperature and flexure. This adds up to the “Best of all worlds” for an engineer designing high performance systems.
Low Loss, Phase Stable Cable
In it’s continuing effort to supply the microwave industry with the highest possible performance, Insulated Wire, Inc., is pleased to announce that it has developed a new line of coaxial cables and assemblies, which has improved the performance characteristics for all type of microwave applications. This new line of cable and assemblies yields smaller diameters, lighter weights, lower insertion loss and enhanced electrical stability versus flexure and temperature. This all adds up to the “Best of all Worlds” for an engineer designing high performance systems. We believe it is imperative that our customer gets the maximum performance, from the widest possible range of products, delivered on time, for the lowest cost.
This new cable line incorporates significant design changes resulting in improved performance. These cables meet or exceed all the material requirements outlined in the MIL-C-17 specification and utilizes silver plated copper conductors, with a very low loss, expanded PTFE dielectric. The outer conductor consists of pure silver, applied in a new proprietary manner that yields lower contact resistance, thus decreasing insertion loss. This new cable line also incorporates a secondary, silver plated, copper braided shield that contributes to excellent RF leakage characteristics, specified at > -100 dB to 18 GHz. The standard outside jacket is a tough, resin melt, extruded FEP, however, PFA, Polyurethane, Tefzel™ and PEEK can be used, depending on the application requirements. IW will also offer an internal ruggedization for cable assemblies, or external armor to provide further mechanical or environmental protection. The internal ruggedization offers enhanced crush resistance and a tighter bend radius. This design offers a more compact package than does the external armor, keeping the size and the weight of the cable assembly down. These assemblies include tough, stainless steel connector bodies. The patented connector designs yield proven performance in the field, on programs, such as, Phalanx, HDR, Cobra Gemini and 767 AWACS.
The 1801 series cable measures .180″ in diameter and typically measures 0.33 dB per foot, at 18 GHz. This is a vast improvement when compared to other available cables on the market, as well as, IW’s previous cable, which measured 0.37 dB per foot, at 18 GHz and measured .230″ in particularly well suited to airborne and satellite applications. The lower insertion loss over long runs of cable allows for less power to be applied, which has the potential to eliminate expensive amplification systems. This new design also yields improved VSWR performance. The typical 1801, (4) four-foot long cable assembly with SMA connectors has a 1.20:1 VSWR to 18 GHz; the 1501 series cable assembly of the same length with 2.9mm connectors has a typical VSWR of 1.25:1 or better to 40 GHz.
The 1401 operating to 50 GHz and the 1501 to 40 GHz make excellent test cables. The very low VSWR and overall electrical stability when flexed, make this cable assembly an inexpensive alternative to the expensive ANA cables. These cables can be ruggedized to withstand production test environments as well as, harsh thermal environments from -65 to +200 degrees Celsius. These cables will withstand repeated flexure and remain within very tight electrical specifications. The 1501 cable data shown for phase stability versus flexure indicate less than a 5 degree change in electrical length at 40 GHz, when the cable is flexed into a tight, 3″ diameter coil. The insertion loss or amplitude stability is also excellent at < 0. 1 dB through 40 GHz.
The excellent stability and high power handling capability makes these cables very good choices for phased array antenna systems. It is extremely important that interconnection cables remain electrically stable during the installation of these sensitive systems. When necessary, IW will phase match assemblies to system requirements. The new cable design allows multiple bends to be put into these matched cables, without significant changes to the electrical length, in addition, this design is very amplitude stable. These cable assemblies typically change < 0.1 dB, at their maximum frequency with the cable bent to the minimum bend radius. The cables are all very flexible and can endure thousands of flexures and remain within the stated electrical specifications set forth.
The low loss nature of these cables allows for higher power levels to be used. This cable technology is being used to help save lives within the field of cardiac medicine. IW is currently supplying a cable used in a microwave ablasion catheter, used to address cardiac rhythm irregularities. The system uses microwave energy to destroy tissue buildup that can cause electrical disturbances and cardiac arrhythmia. IW was selected for this important system because it could offer the smallest diameter cable and worked with the engineers and doctors directly in the development of this cable to achieve the lowest loss, to allow for the greatest amount of power to be applied and keep the catheter within normal body temperatures. As with any of it’s customers, IW goes the “extra mile” to help make a system work properly.
This line of cables is also extremely phase stable when exposed to changes in temperature. It is critical that matched cables change electrically within as small a tolerance window as possible and track in a similar fashion from one cable to the next to maintain proper overall system performance. The change in electrical length must be predictable and consistent. Shown in the graph is a comparison to semi-rigid cable that reflects the improvement that this new design shows over those cable assemblies utilizing solid, PTFE dielectric. The expanded PTFE dielectric material has a nominal velocity of propagation of 84%, making it less reactive to thermal changes when compared to solid PTFE core. The phase profile for this design is very flat and within 600 PPM over a -50 to +120 degree Celsius. This puts this cable among the most phase stable assemblies available from any manufacturer.
The whole line of cables, gives the user great overall flexibility when designing systems. The part number corresponds to the diameter of the cable; an example is the 2401 is actually .240″. These are standard sizes, but IW can manufacture a wide variety of coax cables using this new design to specific customer requirements. IW also offers cables with a 75-ohm impedance that utilizes this new design technique in varied diameters depending on insertion loss requirements.
IW manufactures the broadest line of coaxial cable assemblies available from any company in the microwave industry. Our Microwave Products Division will work closely with its customers, to provide “On-Site” assistance, supporting the successful completion of any interconnection project. IW offers custom, multiconductor cable and assemblies for use, in a wide variety of applications. A complete range of wire and cable products are available including low cost, high performance alternatives to RG cable types. These on-going efforts make IW the industry leader in microwave interconnection technology.
IW supplies internal ruggedization, designated by replacing the ‘1’ in the part number with a ‘3’. This internal ruggedization is available only on cable assemblies. Example: 1801 becomes 1803

Phase Change With Flexing:
Phase change when flexing will be slightly different depending on the particular cable. Larger cables have more dieletric and greater internal forces, thus the phase change of larger cables will be greater than smaller diameter cables. When wrapped 360° around a 4 inch cable diameter mandrel, the phase change will be:
Cables 4806, 2301, and 1801: Phase change = ± 0.30*F.
Cables 1501 and 1401: Phase change =± 0.15*F.
F is the frequency in GHz and phase change is in degrees

Relative intensity noise
Relative intensity noise can be generated from cavity vibration, fluctuations in the laser gain medium or simply from transferred intensity noise from a pump source. Since intensity noise typically is proportional to the intensity, the relative intensity noise is typically independent of laser power. Hence, when the signal to noise ratio (SNR) is limited by RIN, it does not depend on laser power. In contrast, when SNR is limited by shot noise, it improves with increasing laser power. RIN typically peaks at the relaxation oscillation frequency of the laser then falls off at higher frequencies until it converges to the shot noise level. The roll off frequency sets what is specified as the RIN bandwidth. RIN is sometimes referred to as a kind of 1/f noise otherwise known as pink noise.
Relative intensity noise is measured by sampling the output current of a photodetector over time and transforming this data set into frequency with a fast Fourier transform. Alternatively, it can be measured by analyzing the spectrum of the photodetected signal using an electrical spectrum analyzer. Noise observed in the electrical domain is proportional to electric current squared and hence to optical power squared. Therefore, RIN is usually presented as relative fluctuation in the square of the optical power in decibels per hertz over the RIN bandwidth and at one or several optical intensities. It may also be specified as a percentage, a value that represents the relative fluctuations per Hz multiplied by the RIN bandwidth.

Mobile Broadband Communications with Skype
You can use mobile broadband communications as an alternative to other technologies such as mobile phones, and it can save you money! Although mobile broadband is restricted by data allowance (the amount of internet usage), mobile phones are also restricted by the number of minutes and/or texts.
As the internet plays an increasingly important role in our daily lives, using mobile broadband communications as your primary form of staying in touch whilst out and about – put the phone to one side and use your nimble netbook (some mobile broadband contracts even come with free texts!).
One solution to the growing trend in mobile computing is Skype.
What is Skype?
Skype is a great way of taking advantage of the potential of mobile broadband communications. Skype is a little piece of free, downloadable software that allows users to make free skype-to-skype calls. What does this mean? Skype users, from Aberdeen to Zakynthos can call each other on their computers via the internet without paying – great for contacting people overseas who you’d otherwise have to shell out for expensive international calling rates – better than a Facebook message then?
Skype software has dozens of different applications:
> Free Skype-to-Skype calls, be it to your next-door neighbour or your distant relative on the other side of the world
> Send and Receive calls to and from landline phones and mobiles at much cheaper rates compared to conventional phone calls
> Create an ‘online number’ enabling people to call you at local rates
> Send text messages straight from Skype
> Voicemail services
> Call forwarding
> Instant Messaging Services
> Video calls and conferencing
Skype to landline telephone numbers starts at £0.012 per minute, Texts from £0.026 and transferring calls to landline and mobile numbers from £0.012 per minute. Impressive eh? You can save even more (or get premium goods for free) with a subscription as well as a whole other range of other services such as setting up a number for people to call you via Skype.
But at the end of the day, there’s always a cost be it in getting your internet connection to enable Skype to connect. Of course, it says ‘just get to a wifi zone’ – but how easy is that? What if you’re out of range (most public wifi networks can only cover a hundred metres odd, and then only around major public facilities)? What if the network’s locked? Then mobile broadband communications will be your only option.
Comparing the cost of mobile broadband relative to international roaming rates or home broadband is the key question. Whilst wi-fi networks are restrictive and generally online available in public places for “free”. At home, wi-fi comes from your home broadband provider, which of course comes at a cost.
O2 mobile broadband
provides it’s customers with unlimited access to their wifi-hotspot network, ‘The Cloud’ within the UK. Contracts can start for as little as £10 per month, putting it on favourable terms with the cheapest O2 home broadband options, with only a third of the total data allowance for similar tariffs.
But can I use Skype on my phone?
Yes, you can. It’s created a big divide in the mobile phone industry since it totally undermines the requirement for expensive phone contracts with minutes and texts. Some networks completely endorse Skype, such as 3 (Three) who have
'optimized' their network for Skype
and encourage the idea of free calls. The fact is that whilst Skype removes the need for minutes and texts, it simply switches the connection needed to an internet format, again showing how today’s trends are changing.
You can get Skype on your iPhone via the App store and make calls for free (currently via wifi networks only). Still, having already shelled out on an expensive contract the savings with Skype App are from overseas calls. Otherwise you’d simply be using Skype over your existing minutes and texts.
Please bare in mind that some network providers do not endorse or encourage VoIP services (such as Skype) with their mobile broadband services. Please do read all terms and conditions to make sure your contract allows the use of Skype before use. Remember, you can use Skype with any wi-fi network with no problem at all.

Q:How do I Identify my Blaupunkt radio?
A: Blaupunkt radios were manufactured with a series designation and a serial number. The easiest way to tell the approximate age of a Blaupunkt radio is by the series designation, as:
This letter designation is usually found on a "paper" tag/label affixed to the side of the radio. The letter usually is in front of the serial number. It appears from the information I have, that the first part transistor Blaupunkt radios were introduced in 1958-59, with the Koln TR US. This radio would have been mostly tubes, with one or two transistors. In 1959-1960 the Frankfurt TR US appeared, and the conversion to all transistor was completed sometime around 1965. Just a tidbit from an accumulation of information that I have gathered together about Blaupunkt and Becker radios.


Almost linear complexity methods for delay-Doppler channel estimation
Alexander Fish, Shamgar Gurevich
A fundamental task in wireless communication is channel estimation: Compute the channel parameters a signal undergoes while traveling from a transmitter to a receiver. In the case of delay-Doppler channel, i.e., a signal undergoes only delay and Doppler shifts, a widely used method to compute delay-Doppler parameters is the pseudo-random method. It uses a pseudo-random sequence of length \(N\); and, in case of non-trivial relative velocity between transmitter and receiver, its computational complexity is \(O(N^2 logN)\) arithmetic operations. In  the ﬂag method was introduced to provide a faster algorithm for delay-Doppler channel estimation. It uses specially designed flag sequences and its complexity is \(O(rN logN)\) for channels of sparsity \(r\). In these notes, we introduce the incidence and cross methods for channel estimation. They use triple-chirp and double-chirp sequences of length \(N\), correspondingly. These sequences are closely related to chirp sequences widely used in radar systems. The arithmetic complexity of the incidence and cross methods is \(O(N logN+r^3)\), and \(O(N logN+r^2)\), respectively.
