openNetVM is a high performance NFV platform based on DPDK and Docker containers. openNetVM can be SDN-enabled, allowing the network controller to provide rules that dictate what network functions need to process each packet flow.
openNetVM is an open source version of the NetVM platform described in our NSDI 2014 paper, released under the BSD license. Our HotMiddlebox workshop paper is a good way to learn about openNetVM’s overall architecture.
OpenNetVM’s source code and documentation are available on github.
The fastest way to get started with OpenNetVM is using NSF CloudLab. You can find a premade profile here.
Container-based NFs: Writing and managing network functions for openNetVM is easy since they run as standard user space processes inside Docker containers.
NF Manager: This component keeps track of what network functions are currently running in containers and distributes packets to them as they arrive.
SDN-enabled: The NF Manager coordinates with SDN controllers using OpenFlow, allowing the controller to specify service chains composed of multiple NFs that must process a flow.
Zero-Copy IO: Packets are DMA’d directly into a shared memory region that allows the NF Manager to grant NFs direct access to packets with no additional copies.
No Interrupts: We use DPDK’s poll mode driver in place of traditional interrupt-driven networking, allowing the system to process packets at line rates of 10 Gbps and beyond.
Scalable: NFs can be easily replicated for scalability, and the NF Manager will automatically load balance packets across threads to maximize performance.
The OpenNetVM Speed Tester NF can be used to measure the throughput of the system by generating either fake packets or replaying PCAP files to simulate real traffic. To stress test packet movement through ONVM, a service chain of Speed Tester NFs can be run on a single machine, avoiding NIC overheads. Because there is no data copying and each NF handles its own sending and receiving of packets, we get high throughput even for long NF chains. Our measurements at left show that a chain of length two using our NF Direct communication mechanism has a maximum throughput of 32 million packets per second, while extending the chain to seven NFs only incurs a 10% throughput drop. Using indirect NF communication via the management layer sees decreasing performance as the manager’s TX thread becomes a bottleneck.
We have evaluated the performance of OpenNetVM under realistic traffic loads on a machine with eight 10 Gbps NIC ports. If web traffic is directed to a single NF, we observe a maximum throughput of 48Gbps, at which point the NF itself (running a simple forwarding example) becomes the bottleneck. Starting a second replica of the NF allows OpenNetVM to automatically load balance traffic across the two NFs, while preserving flow affinity. This improves performance up to 68 Gbps, which we believe is the hardware limit on our server. Even if the traffic is sent through a chain of 5 NFs, we can still process 40 Gbps.

Power outages can are big concern for people who have to go through it every now and then. It affects the way of life so much as the entire duration of the outage is spent waiting at home and feeling dysfunctional. However, there are software for keeping people aware of power outages and the duration of a power outage. You can get this software integrated into your electrical distribution system so that you can keep track of power outages. This is necessary as people need to know so they can complete tasks that they won’t be able to do later. The system is embedded with an outage web viewer which is made solely for the convenience of customers. On this platform, customers can post the occurrence of a power outage so that their electricity provider can take care of it. It is essential to keep customers updated on the outages that could occur in the future and the duration of the existing outage so that they have some light to hold on to.
An outage management system works by gathering all the relevant and useful information in one place so it can be viewed and analyzed. It collects data from interfaces and systems such as SCADA, AVL and CIS systems. It is also able to collect extremely useful information about power outages from AMR/AMI from which it is able to tell the time when the next outage will occur, its nature and its duration. This makes the electricity providers extremely efficient in what they do as they’re able to know about the occurrence of an outage without the customer even reporting it and are able to send help. The rest of the tools it uses and its features can be viewed at milsoft.com.

Is 0800 Free from Mobiles
When it comes to dialing 0800 numbers from mobile phones, confusion often arises regarding the call charges. Let’s delve into this topic to understand whether these numbers are genuinely free from mobiles or not.
Understanding 0800 Numbers
0800 numbers are toll-free numbers typically used by businesses and organizations for customer service or helplines. Traditionally, calls to 0800 numbers were free from landlines, but mobile charges could apply. However, regulations and practices have evolved over time, leading to variations in cost.
Regulations and Call Charges
In the UK, regulations require that calls to 0800 numbers must be free from all landlines and mobile phones. This means that mobile operators cannot charge their customers for dialing 0800 numbers. However, there might be exceptions for certain mobile tariffs, especially older ones, so it’s essential to check with your mobile provider.
Mobile Tariffs and Charges
While most mobile operators comply with regulations and do not charge for calls to 0800 numbers, it’s crucial to be aware of your mobile tariff. Some older or niche tariffs might still apply charges for these calls. Additionally, calls to 0800 numbers made from abroad might incur international calling rates.
Alternatives and Considerations
If you’re concerned about potential charges for calling 0800 numbers from your mobile, consider alternative options. Many businesses provide alternative geographic or non-geographic numbers for customer inquiries. Additionally, internet-based communication channels like email or live chat can be cost-effective alternatives to phone calls.
In conclusion, while regulations mandate that calls to 0800 numbers must be free from mobile phones in the UK, it’s essential to verify with your mobile operator and understand your tariff to avoid any unexpected charges. By staying informed and exploring alternative communication channels, you can ensure cost-effective interactions with businesses and organizations.

It was inevitable, even from a luddites perspective. Recent history has been guiding us with rapid transitions from mainframe to PC, desktop to notebook, and landline to wireless technology, and we have been taunted with shorter and shorter product life cycles. Breaking news today becomes obsolete technology tomorrow. Yet with all these indicators fore warning of rapid change towards integrated, wireless solutions, we still load up each day with an extraordinary variety of bulky communication and IT equipment, and a wallet of plastic cards. This is about to change, as a result of recent developments in Singapore and the UK.
By the second quarter of this year, we will be able to replace a hand phone, a wallet of plastic cards, a PDA (Personal Digital Assistant), and hard cash, with a single combo device servicing much of our communication, mobile computing, and e-cash transaction requirements. In March, Singapore will launch the first trial mobile phone capable of empowering users to shop, pay for entertainment such as restaurants and movie tickets, and car park charges, using a microchip embedded in the phone. DBS Bank and three mobile phone operators, including Nokia, will be participating in the project. The wireless payment transactions can either be routed to debit a user bank account, e-cash card, or credit card. Settlement will be initiated by using the latest developments in the Short Message Service (SMS), Wireless Application Protocol (WAP), Infrared, and Bluetooth technologies.
In parallel with developments in Singapore, Handspring introduced to the UK and East Asian markets in January the first lightweight PDA with a built in cell phone. Called the Treo, the device is designed for Global Systems for Mobile Communication (GSM) mobile transmission technology. Palm is also planning a similar PDA/Phone launch. Integrating PDA, email, and phone is considered the focal point for development amongst PDA manufactures. Sagem and Mitsubishi are already promoting earlier generation (heavier, larger) models, and Samsung and the British wireless operator, O2 are planning model launches this year. By midyear, the market is expected to be awash with new integrated mobile devices.
All this signals the end of mobile phones and PDA’s as we know them; functionality will be merged. More significantly, the developments heralds the end of the Smart Card. Plastic cards were an ideal medium to support ‘magnetic stripe’ technology. The significantly more intelligent microchip technology no longer requires a plastic card to support processing. As we are now seeing, the microchip is migrating to the multi functional, multimedia environs of the mobile phone. The Smart Card is destined to become redundant in its infancy. This presents an interesting conundrum for banks and governments, who have been struggling with Smart Card technology for years. To banks, the Smart Card represented a Trojan Horse seething with competitive threats from new fringe banking operators. It was ignored by bankings high priests as a nasty apparition of the future! Banks, for all their past pontificating and procrastination must now face up to the reality that these developments in mobile wireless technology (specifically as they effect E-Commerce) will further erode the boundaries of their traditional business empires.
Governments on the other hand have longed for the ID card potential that the new Smart Card technology can deliver, but they haven’t been able to access it (in most cases) due to privacy protection policies. This may have been their saving grace! Those governments that haven’t already adopted Smart ID Card solutions stand to steal a march on those that have, and in so doing, save millions in taxpayer dollars.
Smart ID Cards, such as the MyKad already being implemented in Malaysia, and a similar ID card proposed by the Hong Kong government, use digitised fingerprints (minutiae) recorded onto a microchip which is embedded into the ID card. Both cards will contain other applications besides ID. The number of applications is only limited by the size (and therefore processing capabilities) of the microchip. The MyKad for instance, uses a 32kb microchip embedded in the card for multiple application processing (Passport, National ID, Driver License etc). Larger 64kb microchips are already being designed to support a greater number of applications that can also be dynamically added, amended, or deleted by the owner. However, both the MyKad and the proposed HKID will be outdated by the time roll out is complete. They will be outdated for two reasons. Firstly, all the information they contain, including biometrics data, will be available on a microchip that can be embedded in mobile phone combos. Available that is, as long as we all carry a mobile phone combo! But, what if we don’t? It becomes irrelevant, as the authorities certainly will, and that is the second reason why the cards will be redundant. If we take guidance from the recent rate of technology change, within two years, the processing capabilities of the microchip, coupled with continuing developments in wireless communication, will obviate the need for any of us to carry ID. Our unique biometrics will be our ID, and can easily be read by existing biometrics readers carried by authorized personnel (police, immigration officers etc.,) using a microchip in ‘their’ mobile device. The captured minutiae could then be compared with possible ‘hot lists’ of offenders stored on the microchip, and/or with records maintained on a centralised database accessed through the combo device. Bingo, ID check made, and no need for the despised ID card (or the enormous taxpayer expense to implement it).

Bell offers Prince Edward Island residents upload speeds 12 times faster compared to the combined speeds of other broadband providers in the area, according to data collected from Speedtest Intelligence in the fourth quarter of 2021.
Speedtest is a tool by Ookla that tests fixed broadband and mobile performance data worldwide.
The recent analysis examines fiber connectivity across Canada, focusing on Bell and Telus, given they serve different parts of the country. Their speeds are compared to the average speeds of other companies that serve the area.
Bell also offered faster median download speeds compared to the market average in New Brunswick, Newfoundland, Nova Scotia, Ontario, and Québec. Telus offered faster services in Alberta and British Columbia.
Bell also led with upload speeds compared to other fixed broadband offerings in New Brunswick, Newfoundland, Nova Scotia, Ontario, PEI, and Québec. Telus led in upload speeds for Alberta and British Columbia.
Bell and Telus don't provide service in Northwest Territories, Nunavut, Saskatchewan, and Yukon, impacting services in each province.
For example, the average download speed in Saskatchewan is 68.43Mbps, and the upload speed is 17.04Mbps. This is much slower than the speeds in New Brunswick. Serviced by Bell, the download speed is roughly 160Mbps, and upload is around 120Mbps.
"Infrastructure improvements like laying fiber are very expensive as they often require providers to dig up city streets to physically lay new lines. This often means that fiber deployments are limited to areas with high population density where providers are more likely to recoup costs."
The analysis shows laying down fiber is worth the cost. In Halifax, for example, fiber upload speeds by Bell are 11.4 times faster than other fixed broadband options. Bell also offered faster upload speed in London, Montréal, Québec City and Toronto. Telus offered faster upload speeds in Calgary, Edmonton, and Vancouver, compared to other options.

Researchers at the Karlsruhe Institute of Technology (KIT) in Baden-Württemberg, Germany, set a world record for transmitting 100 gigabits of data per second over a distance of 20M in the lab.
In their world record experiment, 100 gigabits of data per second were transmitted at a frequency of 237.5 GHz over a distance of 20 m, in the laboratory. In previous field experiments under the “Millilink” project, funded by the BMBF, rates of 40 gigabits per second, and transmission distances of more than 1 km were reached. But for this latest world record, the scientists applied a photonic method to generate the radio signals at the transmitter. After radio transmission, fully integrated electronic circuits were used in the receiver.
“We have managed to develop a radio link based on active electronic circuits, which enables similarly high data rates as in fiber-optic systems, therefore allowing seamless integration of the radio link,” said Professor Ingmar Kallfass, coordinator of the project at Fraunhofer IAF. The device uses 80 GHz of spectrum between 200 and 280 GHz. The atmosphere has less attenuation at this frequency.
Jochen Antes of KIT noted that: “This makes our radio link easier to install compared to free-space optical systems for data transmission. It also shows better robustness in poor weather conditions such as fog or rain.” There is room for improvement. Antes added, “Improving the spectral efficiency by using more complex modulation formats or a combination of several channels, i.e. multiplexing, will help to achieve even higher data rates.”
Researchers believe that in the future, such radio links will be able to close gaps in providing broadband internet by supplementing the network in rural areas and places which are difficult to access.
Professor Ingmar Kallfass also believes, that it will be applications (with such radio links), for private homes: “At a data rate of 100 gigabits per second, it would be possible to transmit the contents of a blue-ray disk or of five DVDs between two devices by radio within two seconds only” he says.
This technology could be ideal for providing the last kilometer connection for “fiber to the home” services, especially in rural areas where it could be a cost-effective and flexible alternative to fiber.
In conclusion, cheaper is better, as this technology promises. And it could replace cable expansion of networks across waterways, the last mile to the home, and other areas where a line of sight laser system, such as this, is more economical. So, we just have to be patient…

A battery should discharge it's stored energy through a high-current capable discharge connector. Usually this connector is polarized to avoid connecting it to the helicopter's electronics incorrectly.
Some batteries, particularly lithium polymer batteries, have an additional balance connector that allows the individual cells to be addressed for balanced charging, but are unsuited to the high currents needed for flight.
Common discharge connectors include:
- Banana ('bullet') connectors (Max 70A for 4mm);
- 'JST' (JST RCY series) connectors (Max 5A);
- Ultra Deans connectors (Max 100A);
- Micro Deans connectors (Max 15A);
- Tamiya (Molex) connectors (Max 20A);
- AstroFlight Zero-loss connectors (Max 50A);
- Anderson Powerpoles (Max 45A to 180A, depending on size).

It used to be that if you wanted to hear music in every room of your house, you turned your stereo up really loud and hoped the neighbors didn't complain.
If you live in the middle of nowhere, this might still work—but even if cranking the stereo loud enough to hear everywhere isn't a problem, it's far from ideal.
That's where whole home audio systems (also known as multi-room audio) come into play. These are different from simply expensive speaker systems that can play loudly enough to hear music in every room.
In this article, we'll explain what whole home audio is, why it's a useful way to listen to music in every room, and whether you might be able to do it with speakers and devices you already own.
The Basics of Whole Home Audio
As a concept, whole home audio is simple:
You place several different speakers around the house, and these speakers are connected to each other (usually wirelessly). When you play music in one room, you can automatically distribute that music to all connected speakers throughout your home.
Of course, while the concept is simple, the practical setup is a little more complicated.
With wireless multi-room audio, sending and receiving the signals is simple enough... but syncing everything up so that the music you're hearing sounds the way it should is tough.
That's why high-quality whole home audio systems can get pretty expensive. If you don't want to drop that kind of money, there are some cost-effective options you can consider first.
Whole Home Audio With Smart Speakers
If you own a smart speaker—like most of the devices in Amazon's Echo line or an Apple HomePod—then you may already be capable of making your own whole home audio setup.
If you only have one smart speaker, you can try complementing it with cheaper "satellite" speakers that are designed to work with your brand of smart speaker.
For example, Apple's HomePod mini costs around $100 and works with Apple HomePod speakers. The Amazon Echo Dot is much cheaper at around $40, which works with any of the "main" Amazon Echo smart speakers.
Going through the setup process for each of these is beyond this article, but it should be relatively simple to get multi-room audio going with Apple, Amazon, and even Google smart speakers.
Once you've got enough speakers to cover every room (or nearly every room) in your home, you're all set.
Are Whole Home Audio Systems Worth It?
If buying individual speakers and connecting them together on your own sounds like too much work, you have another option: manufacturers like Sonos, Denon, and Bose all sell whole home audio systems ready to go.
Some of these multi-room audio bundles can get pretty big—and the price goes up as a result.
If you live in an apartment or a relatively small house, the costs won't be too astronomical. But if you live in a huge home, you may have to buy several extra speakers to cover every room.
The main downside of whole home audio systems is that they're mainly designed for customers who are used to paying a lot for nicer things.
This means that even the cheapest whole home audio systems are significantly more expensive than the one-off smart speakers by Amazon, Apple, and Google.
For example, Bose's home speakers start at $200 and Sonos' two-room speaker sets start at $360.
But the extra price is often worth it for two reasons.
First, everything in a whole home audio system works together out of the box, so they're much more convenient to set up.
Second, the companies that make whole home audio systems are audio-first or audio-only companies, so they're specialized in creating high-quality audio solutions. The sound quality and user experience are far better than what you get in a smart speaker.
What About the Audio Quality?
While we've looked at how you can distribute music throughout your entire home, we haven't really looked at how good it will sound. Of course, this largely depends on the quality of speakers you're using.
The reason that Sonos and other whole home and multi-room audio systems are so expensive compared to an Amazon Echo is that they're using much higher-quality speakers.
They'll often also use much more complex internal processing to make your music sound like it's coming from all over the room, or at least from a larger speaker.
While smart speakers can sound much better than you might guess based on their size, they still don't hold up as far as audio quality. (But they can be impressive for the price.)
You Can Always Keep It Simple Instead
For some people, whole home audio is a lifelong dream finally realized. Paired with smart speakers with voice assistants, it can make you feel like you're living in the future.
But if all of this sounds like a headache, don't worry about it. Music will still sound fine on an old-fashioned stereo or even a cheap Bluetooth speaker, if that's all you're looking for.

A quantum internet is a quantum network in which the processors are located at different geographical locations. Our goal is to develop the technology to enable quantum communication between any two places on earth. One application of such a quantum internet is to provide a fundamentally secure way of communication, in which privacy is guaranteed by the laws of physics.
Quantum processors can be connected into a quantum network in order to assemble a large quantum computing cluster. This approach is called networked quantum computing and offers a natural path towards scalability, complementary to the quantum computing work described in the previous chapter. Combining a quantum internet and a networked quantum computer allows remote users/providers to perform secure quantum computing ‘in the cloud’.
Quantum network protocols and applications
Long-term goal: Development of a full control stack and novel applications for a quantum internet.
2019 Research Highlights:
- We developed a so-called link layer protocol that brings the phenomenon of ‘quantum entanglement’ from a physics experiment towards a real-world quantum network. The link layer protocol allows to reliably generate entanglement between two network nodes connected by a direct physical link, without the need to know which quantum hardware system is in the box. The work was presented at ACM SIGCOMM. Read more
- We co-organized a pan-European hackathon which simultaneously took place in Paris, Genève, Sarajevo, Padua, and Delft. The hackathon was organized within the framework of the EU-funded Quantum Internet Alliance (QIA). It attracted ca. 100 participants who took on various different challenges related to first applications that use quantum physics to secure online communications.
- We have analyzed different protocols through which near-term experiments with NV centers can overcome the limitations of direct transmission. This work points towards first proof-of-principle experiments in which entanglement generation between end nodes connected by high-loss channels can be sped up. We report on this in Phys. Rev. A.
Quantum network experiments
Long-term goal: Experimental demonstrations, some of which already compatible with existing telecom infrastructure, that push the frontier of quantum networking and yield new techniques and insights.
2019 Research Highlights:
- Europe aims to deploy a quantum communication network providing quantum key distribution (QKD) as a service. It is possible to benefit from existing infrastructure by having the quantum communication signal coexisting with the classical one over the same fiber. This will help to minimize operating costs and hence facilitate deployment. We showed that measurement-device independent (MDI) QKD can operate simultaneously with classical communication channels operating at around 1550 nm wavelength and over 40 km of spooled fiber, with projected communication. The similarity of MDI-QKD with quantum repeaters suggests that classical and generalized quantum networks can co-exist on the same fiber infrastructure. The work was published in Quantum Sci. Technol.
- We demonstrated that conversion of single photons emitted by NV center qubits from the visible to the telecom band (where losses in fibers are minimal) preserves entanglement of the photon with the qubit. This is a key result for extending quantum networks based on diamond-based quantum processors to large distances. This work was published in Phys. Rev. Lett.
- We reported on the storage and reemission of heralded telecommunication-wavelength photons using a crystal waveguide in Phys. Rev. Applied. Despite currently limited storage time and efficiency, this demonstration represents an important step toward quantum networks that operate in the telecommunication band and the development of integrated (on-chip) quantum technology using industry-standard crystals.
Quantum processors for quantum networks
Long-term goal: Develop and exploit multi-qubit quantum processors for use in quantum internet and networked computing, with current focus on diamond-based spin qubits.
2019 Research Highlights:
- We demonstrated a fully controllable chip with ten qubits that can store quantum information for up to one minute (Phys. Rev. X). Controlling such a large number of qubits with long memory times is an important step forward for chip-based qubits and might pave the way to large multi-qubit quantum systems. Read more
- We developed non-destructive measurements of a joint property of multiple qubits, namely their parity (Phys. Rev. Lett.) We explicitly showed that these measurements can be applied repeatedly to three nuclear spin qubits without destroying their joint quantum state. These measurements are key ingredients for error correction and measurement-based computing schemes.
- Using novel quantum control techniques, we succeeded in imaging 27 nuclear spins surrounding an NV center spin qubit. These unprecedented control and imaging capabilities pave the way for extending local quantum registers in network nodes well beyond 10 nuclear spins. Our findings were published in Nature.

Zaragoza, Spain – Libelium announces the launch of Libelium OTA, a solution that lays the foundation for over the air programming (OTAP) for wireless sensor networks and the Internet of Things.
This brings OTA capabilities for the first time to unlicensed frequency bands (2.4 GHz, 868 MHz, 900 MHz) and to low power communication using protocols such as 802.15.4 and ZigBee.
Over the last decade wireless programming or over the air provisioning (OTA) has been widely used by the mobile phone industry. This capability has allowed software updates to be delivered to mobile phone users and to enable the deployment of new services as they become available.
So far, such capabilities have not been available to wireless sensor networks or to the Internet of Things. Such networks, usually consisting of hundreds or thousands of nodes (“motes”), would benefit from an OTA capability.
David Gascón, Libelium’s CTO, says “Motes are often located in places that are either remote or difficult to access. Libelium OTA will enable firmware upgrades to be made over a wireless network without the need of physical access”.

I recently helped a customer who built a new office in her backyard. She had shaw internet in the house and did not want to pay shaw for a second connection in her new office. She had an existing wireless router in her house but the connection would not reach to her office. I purchased a product from DLink called a wireless expander. Once configured to match her existing wireless network it extended the signal far enough to reach the office. We added a wireless card to her desktop computer and were able to make a strong connection to the wireless network. This same wireless expander can be plugged into any outlet in your home to expand the range of your wireless network. Please give me a call with any questions. Trevor.


On July 1, a node equipped with Shelley upgrade components was deployed onto the mainnet. By the month’s end, on July 29, the changes will be implemented on Cardano’s network through a hard fork.
The new Shelley upgrade has had a significant impact on the ADA price because of its staking system. Cardano is a proof-of-stake network, which means there are no miners. Users, who run nodes, maintain the network by staking ADA. In return, users benefit from the reward system of Cardano.

have a Cyber Cell?
The prefix ‘Cyber’ typically relates to computer hardware,
software & networks (including internet) and to flow of information
or communication. The world today is experiencing unprecedented
growth in the number of users of computers & of internet.
There exist over 1 billion internet users the world over. India,
with its 55 million users, ranks 4th in the world. The plummeting
prices of PCs/Laptops/Palmtops and availability of cheap, high
speed internet access shall further drive the growth in the number
of computer users. A parallel development has been the telecommunication
revolution with the advent of the mobile phone technology. India
already has over 100 million mobile phone users and the number
is expected to rise further with falling call tariffs and availability
of cheap handsets. The two areas of information flow are getting
integrated over time with internet providing PC-to-PC call facilities
and with mobile phones providing mobile access to internet.
This rapid development in the area of information technology today
poses new challenges for the police department. The use of internet
and computer systems has led to new types of ‘Cyber Crimes’
like malicious emails, fraudulent electronic transfer of money,
misuse of stolen credit cards etc. Similarly, the introduction
of the mobile phone technology has destroyed the competitive edge
that the police department had enjoyed by having the exclusive
right to use wireless communication. Today, the criminal elements
enjoy an equal access to mobile communication. The incidence of
theft/snatching of mobile phones is rising rapidly. The criminals
today, are increasingly using mobile phones for effecting different
kinds of crimes such as making extortion calls, detonating IEDs
etc. There is a need to have a specialized group with the requisite
technical skills to assist and guide the investigative arms in
overcoming challenges posed by recent technological advances in
the sphere of information technology.
What shall the Cyber Cell do?
Cell of Mewat Police has been established as the nodal agency
for providing all possible technical assistance to the different
investigative units in matters pertaining to mobile phone technology
and internet. The cell is rapidly developing expertise in areas
like call monitoring, tracking down of stolen mobile phones etc.
The cell is being equipped with sophisticated hardware. Assistance
from software experts is also being solicited in order to upgrade
the computer skills of Mewat's Cyber Cops.

Additional resources for 4G LTE/LTE-Advanced for Mobile Broadband
Mobile-communication systems should preferably be designed to be able to take advantage of such scenarios – that is, they should be able to offer very high data rates within a limited bandwidth when the radio conditions so allow. A straightforward means to provide higher data rates within a given transmission bandwidth is the use of higher-order modulation, implying that the modulation alphabet is extended to include additional signaling alternatives and thus allowing for more bits of information to be communicated per modulation symbol.
A second drawback of multi-carrier transmission is that, similar to the use of higher-order modulation, the parallel transmission of multiple carriers will lead to larger variations in the instantaneous transmit power. Thus, similar to the use of higher-order modulation, multi-carrier transmission will have a negative impact on the transmitter power-amplifier efficiency, implying increased transmitter power consumption and increased power-amplifier cost. Alternatively, the average transmit power must be reduced, implying a reduced range for a given data rate.
11. This is often expressed as a one-tap equalizer being applied to each received subcarrier. 11). To be able to do this, the receiver obviously needs an estimate of the frequency-domain channel taps H 0 , …, H N c Ϫ1. The frequency-domain channel taps can be estimated indirectly by first estimating the channel impulse response and, from that, calculating an estimate of Hk. However, a more straightforward approach is to estimate the frequency-domain channel taps directly. 12. Using knowledge about the reference symbols, the receiver can estimate the frequency-domain channel around the location of the reference symbol.
