The industrial internet of things is a term that we’re getting more used to seeing. But do we really know what it means and the effect it will have on business?
It’s been called the fourth industrial revolution and promises to disrupt and ultimately improve the way we as humans interact with machines and big data.
Google tells us that:
The IIoT is part of a larger concept known as the Internet of Things (IoT). The IoT is a network of intelligent computers, devices, and objects that collect and share huge amounts of data.
The Internet of Things
The internet of things connects machines, product diagnostics, software and analytics so the businesses can operate more efficiently.
The best example of this is with smart heating systems.
Companies like Nest give consumers control over their heating through linking up via mobile devices. We can turn them up, down, on and off from our mobile phones away from our homes.
Some devices can even tell if you and your smartphone have left the house and will turn the heating off automatically, or set it to turn off when it’s a sunny day.
The benefits of these types of systems in our home are obvious, we are becoming more economical with our resources and have more control over our lives and our homes.
Wearable tech is also becoming mainstream with people exercising; wearing smartwatches of wrist bands to monitor their heart and distance travelled.
And it’s not stopping at our home, there is talk of smart cities, where traffic signals monitor use and bins signal when they need emptying.
The Industrial Internet of Things
The Industrial internet of things (IIOT) is where industry starts to utilise this technology to increase efficiency, eliminate waste and improve health.
· Manufacturing is furthest ahead with the organisation of tools, people & machines; tracking stages and process.
· Farming is starting to use sensors to manage crops and cattle to boost production and the health of their animals.
· Healthcare is also expanding with smart pills and monitoring patients health through wearable tech. Intel created a smart band which tracks how much a person shakes with Parkinsons and Sonamba monitors activities of older and ill people.
The driving force behind all this tech is that ultimately smart machines are better able to consistently and accurately capture and communicate data.
The downside could be that as we become more reliant on tech, breaches of security become more of an issue. And some companies have been accused of treating staff like machines, monitoring toilet breaks with workers being squeezed for more productivity.
Here are 5 facts you need to know about the IIOT from The Manufacturer
1 – This growth in the Industrial Internet will increase manufacturing profitability by 21%
2 – There are 1.5 trillion objects on this planet. Only 0.6% of them are connected.
3 – In 1822, Charles Babbage designed the first automatic computing engine and Ada Lovelace created the first computer programme in 1843. By 2022, there will be over 50 billion objects connected to the internet.
4 – The biggest impact of the Industrial internet will be in manufacturing.
5 – The digital transformation will boost business. GE estimates the Industrial Internet could be a £174bn market by 2020.
Industrial Internet of Things at G2 Innovation
The IOT is not new to G2, we’ve developed our own products and worked with clients to develop theirs. We’ve produced hardware, software and the packaging and enclosures to make products user friendly and accessible.
When we’re not developing IOT tech, we’re also teaching it. Tom and James both teach Arduino programming at our local HackSpace.
We'd love to hear from you if you've got a project you're working on that we could support you with. Feel free to get in touch.

[MWC16] Oppo announces a bunch of innovations
Oppo is more of an innovation factory than a regular mobile OEM. Oppo launched the first full HD smartphone. They introduced rotating camera on a mobile. They have a endless list of innovations in their kitty. The proprietary technology for fast charging is called VOOC. The VOOC charging technology can charge a mobile from 0 to 75% in 30 minutes. It is currently available in about 5 models from Oppo.
Super VOOC Flash Charging
At the MWC, Oppo has not introduced any new mobiles this year. Instead they have announced a couple of innovations that will be featured in their future models. The next version of VOOC is called the Super VOOC. The Super VOOC can charge a 2500 mAh battery from 0 to 100% in 15 minutes. It can charge it to 45% in 5 minutes. Super VOOC requires a new flash charger and a special cable along with military grade connector. But the connector can be of USB-C or microUSB type. The charging adapter holds the key to this technology. It has a special intelligent chip to enable super fast charging. The adapter circuit ensures safety with its five level protection system. Also Oppo promises that the temperature of the smartphone, during charging will be significantly lower. Though the technology is in experimental phase, Oppo promises to bring it to its future lineup.
SmartSensor Image Stabilization technology
Oppo also unveiled its latest innovation in photography. Oppo introduced the SmartSensor Image Stabilization technology. Mimicking the stabilization techniques used in mirror-less camera, the SmartSensor Image Stabilization technology moves the sensor to compensate for vibrations. In a typical camera, lens or a mobile, only the lens sits on the image stabilization system. Oppo claims that moving the sensor as opposed to the lens enabled a faster stabilization system. Sony R7 MII camera offers 5 axis compensation and with this technology, Oppo mobiles can offer 4 axis stabilization.
On another note, Oppo has filed a patent for mobile to change themes based on your outfit colors. This is very similar to Chameleon color picker app found on Gionee mobiles.
With such innovations around the horizon, Oppo is definitely a key player in the future of mobiles.


Despite the new hype neighboring IoT, there is a risk that IoT technology isn’t a protected enough platform for your info. These linked devices can be used to eavesdrop on your own home and intercept your personal information. Luckily, there are solutions to protect your network and keep your data safe.
One of the most common ways to protect your network is usually to install anti-virus security program. These reliability products support detect and block malicious efforts to connect to your IoT gadgets. You can also apply antivirus reliability software to monitor the network with respect to suspicious activity.
Another important net-software.info/how-to-delete-backup-files-in-windows-10/ step you may make to protect your network should be to check with the manufacturer to see if you may download a downloadable secureness patch. This will help fix virtually any bugs that will be affecting your machine.
While you’re in it, you have to ensure that your router is set up with a secure security password. If your router actually secured, a malicious attacker can connect to the IoT products without your understanding.
The best way to protect your network right from a web attack should be to segment your network. Segmenting your network will help you prevent having jeopardized devices connect with your primary network. This is a common practice in the corporate and business world nonetheless it’s also a smart idea with regards to IoT products.
Another thing you should do is to establish a electronic LAN. This will help isolate your IoT gadgets from your most important network. This will also offer you an extra level of security.

Do your employees move to and from their desks—or the back warehouse? With SIP cordless phones, they can do just about everything on a cordless handset that they can do on a deskset—hold, transfer, conference, and even intercom between other handsets.
Communications trends don’t affect just your business—they touch all SMBs and enterprises. Technology surrounds us and continues to evolve, especially when it comes to communications. We've compiled a list of seven trends, which play into the decisions you'll likely consider when moving to VoIP.
More and more SMBs choose to migrate to VoIP, and replace their premise-based legacy phones with SIP phones. Until recently, only large enterprise companies had the budget to move telephony to the cloud. But now, this technology has become more cost-competitive, making it accessible to smaller business.
When considering SIP phones, it’s important to have a broader perspective of why you’re moving to VoIP and the benefits your business will experience.
Current statistics forecast millennials overtaking baby boomers as the nation’s largest living generation by 2019, with projected numbers climbing well over 73 million. Examining today’s workforce reveals a similar trend. Millennials have already surpassed baby boomers, making up 35 percent of today’s employees. Yet as businesses adapt to the shifting demands of a new generation of workers, they can’t neglect the needs of current employees. Luckily, the modernization of key infrastructure can address the needs of these two different populations. One modernization includes communication tools.

Native Network is a beta feature.
A native network allows you to communicate between different ROS environments as described in the following scenarios.
Native networks eliminate the need of creating a separate routed network for the local communication and significantly decreases the latency as the communication doesn’t involve a cloud bridge for individual ROS environments for communication.
In case of native network, multiple ROS environments (all ros nodes sharing the same ROS_MASTER_URI are considered a single ROS environment) can discover each other (these could be filtered based on the list of topics/services provided) and the communication happens in a peer-to-peer manner. Each ROS environment has its own ROS master and the rapyuta.io platform uses a sub-component based on the open-source FKIE multimaster to achieve it.
for tf topic: if you don’t add tf_prefix, don’t expose the topic as there is a possibility of mixing of tf.
Compression, QOS, and Service Timeout are not applicable in the case of native networks.
For the use case, let’s take an example of 3 ROS packages:
We want to establish communication between these 3 ROS packages. To simplify this communication, you can use a native network that serves as the best medium for communication.
The result is as follows
We can establish this communication by using a cloud routed network. However, using a routed network involves cloud bridge for each ROS environment that adds latency when service/action/topics are being called in the same local area network.
Communication through a native network is happening in a peer-to-peer manner that means the subscriber directly makes a connection with the publisher thereby eliminating the latency in each hop-on of messages as in the case of a routed network via cloud bridge. This results in low-latency communication.
You can see the list of publishers whitelisted in your package components in your rostopic list command.
Native network is very similar to the local single ROS master environment.
When you subscribe to a topic from a different ROS environment, this subscriber information is kept locally and only shared if a topic is whitelisted in a package component.
When you deploy a native network to the cloud, it is considered as a cloud native network. Any compute resources (CPU/memory) consumed by this native network deployment count against your cloud deployment hours quota.
When creating a cloud native network, the Resource limit field defines the memory allocation and computational capability of the native network. These resources are reserved in the platform for effective ROS communication. You can choose the resource limit of a native network based on the following requirements.
You can connect your deployments to more than one cloud native networks for redundancy.
When you deploy a native network to a device, it is considered as a device native network. This allows for ultra low latency peer-to-peer connections between ros nodes in a Local Area Network(LAN) i.e ONLY deployments on devices on the same LAN can bind to it.
Native networks can be deployed to devices that fulfill the following requirements:
To use device native networks the user needs to re-onboard the device (to install and enable the new services). Also ensure that cpuset and memory cgroups are enabled.
For instance use native networks with a Raspberry-Pi consider adding the following in /boot/cmdline.txt.
cgroup_enable=cpuset cgroup_enable=memory cgroup_memory=1
On reboot, devices configured using DHCP may boot up with a new IP address and the network configuration of a deployed native network becomes invalid. This can be avoided by assigning a static IP to the device you intend to deploy a native network to esp in production systems.

You may be eligible for the government gigabit voucher scheme which saves you up to £2500 off the price of the leased line price we quote online, please contact us today to see if you are eligible once you receive our quote by email. The discount is only available for leased lines above 100Mbps speeds.
LeasedLineCompare.co.uk are one of the UK’s leading Leased Line providers, we are part of a larger group of companies owned and managed by Stride Communications Ltd . We have massive wholesale Leased Line purchasing power and can offer great Leased Line pricing to small, medium and large businesses. We will look at all types of dedicated internet access available to you from all providers and get you the best ethernet deal available for you in your location. Download our brochure by clicking on this link
With a leased line the service is dedicated to your business. This means the bandwidth is uncontended so purely for your use meaning the speed will not fluctuate during peak times unlike with other services such as standard copper or fibre broadband. You can be guaranteed that if you buy a 100Mbps leased line that you will get 100Mbps available for you to use. This is particularly important when you use bandwidth reliant applications such as VoIP, cloud applications or if you have a sizeable user base.
With a leased line you get the same upload speed as download speed. This is also known as symmetrical or synchronous bandwidth. Traditionally the upload speed is much lower than the download speed on standard copper or fibre broadband connections so you will see a vast improvement with synchronous speeds. The upload speed is critical even for web browsing as you have to upload your request to view a website before you can download the website, everything on the internet is a two way conversation with both upload and download required. This is even more critical for applications like VoIP, cloud applications, remote users and enables you to send and upload large files quickly.
Leased lines do not come with any usage cap, it is a truly unlimited service and there are no fair usage policies.
99.999% uptime guarantee – leased lines come with the best service level agreements which cover features such as uptime, speed, availability, jitter, latency and packet loss. Service providers have a matter of hours to fix a circuit in the event of a total failure. If they ever failed to meet these guarantees then they would have to pay financial penalties.
You can choose between a managed circuit or a wires only circuit. Managed circuits come with free use of a managed pass through router, this also enables 24/7/365 active line monitoring of your circuit to detect any faults instantly so the providers can work on fixing them straight away. You will put your own router on top of this to provide DHCP and a firewall etc. Alternatively you can opt for a wires only circuit where you provide your own router to connect to the end of the leased line.
Because a leased line is the best business grade internet service, it comes with the best business grade support. You can contact us 24 hours a day, 7 days a week, 365 days a year to report a fault should things go wrong.
Static IP addresses are used to operate certain services such as VPNs, email servers etc. Usually you receive a block of 4 Static IP addresses. If you need more you can request this, we will just need a justification for the IP addresses.
If you need extra redundancy we can provide a fully managed, automatic ADSL2+ or FTTC (if available) backup. These seamlessly failover in the result of your leased line circuit going down also keeping the same IP addresses then automatically switch back to your leased line when this is back up.

If your tech enthusiast probably were wondering about upgrading to WIF 6 router. So before upgrade to WIFI 6, we also need the clients to support wifi6 to take advantage of the features.
Now we shall dive deeper into what WIFI 6 offers.
1) The WIFI 6 router offers higher bandwidth starting from 1.5Gbps to 9.6 Gbps, And we can identify the bandwidth by the name. i.e. my router name contains AX 1500, So AX represents the alliance standard and the numeric 1500 represents the total bandwidth, so my router has 1.5 Gbps of bandwidth
2) Improved MU-MIMO, typical WIFI 5 router could connect with 2 to 4 streams and WIFI 6 routers could have 4-8 streams, So even the legacy devices could make use of this.
3) Improved frequency modulation from OFDM(Orthogonal frequency division multiplexing) to OFDMA (Orthogonal Frequency Division Multiple Access).
So in plain simple English. The 5 GHz spectrum divided into multiple channels and further shared between multiple users as sub-channels so the single link can be used by multiple users,
This process is referred to as FDM(frequency division multiplexing).
So in OFDM Orthogonal signal is used to achieve higher bandwidth and less interference, OFDMA extends to communicate with multiple clients at the same time so theoretically more client at a given time. but again needs wifi 6 client.
4) Improved power efficiency on the clients by using target wake time TWT (wifi6 client needed)
5) Higher data bandwidth using new 1024-QAM modulation (wifi6 client needed)
These seem like a lot of improvements but how does it work for an average user.
Frankly speaking, I have almost 15+ devices in my network and 8+ devices are constantly active, out of 15+ devices only 2 devices are WIFI 6 devices.
So these are the improvements I was able to notice after upgrading my router.
1) Saw almost 10% of battery improvement on my phone which is on WIFI 6, And I was able to notice this improvement when the phone is idle and has an active WIFI connection.
2) Due to improved hardware, connections on the legacy device were stable. not just because of wifi6
3) On WIFI 6 devices, I was could notice very low latency, and higher bandwidth especially sharing files over WIFI. And more stable internet speeds.
4) On my TVs I was able to see less buffering during streaming,
maybe because of improved bandwidth or because of MU-MIMO (not a WIFI 6 device).
So to conclude upgrading to WIFI 6 router is worth when:
1) when the internet speed is more than 500 Mbps and has a client to make use of the bandwidth.
2) Huge benefit when the connected client is WIFI 6 compatible
3) useful for small offices when the laptops are WIFI 6 compatible
4) will help if you are into gaming coz of lower latency during the multiplayer gaming session.
wait till you have at least 5 or 6 devices are wifi6 compatible, or when there are 15+ devices, WIFI 6 devices will be benefited from a stable connection

EcoG – Pioneering the Megawatt Charging System and working with the truck and bus industry on interoperability
- EcoG offers the technology necessary to kickstart the development and market introduction of the Megawatt Charging System (MCS), which will be essential for charging electric trucks and buses.
Munich, June 9, 2023 – EcoG has an MCS starter kit and controllers available at EVS36 Sacramento 11th-14th June 2023 – Stand 10, Booth 509.
EcoG (ecog.io/) is a technology company allowing businesses to rapidly develop reliable and interoperable charging stations for electric vehicles (EVs) globally. As an established market leader and innovator, EcoG is pioneering Megawatt Charging System (MCS) technology that will boost the sustainable commercial vehicle industry and open up electrification to larger, high-power vehicles.
The EV industry is pivotal to reducing carbon emissions and vehicular pollution over the next decade, as part of humankind’s last chance to prevent a 1.5C global temperature increase. MCS is the next significant infrastructure advancement in electric mobility, addressing the need for sustainable charging solutions for commercial vehicles. MCS extends the core technologies of Combined Charging System (CCS), which are used to charge all of today’s passenger and light-duty EVs, for an even faster charging solution for electric trucks and buses.
EcoG’s charge controllers and reference architectures allow EV charging station manufacturers to kickstart their charger development for heavy-duty electric vehicles, with a short lead time to market. EcoG also helps conduct early interoperability testing with manufacturers of electric trucks and buses.
EcoG is driving the development and rollout of an MCS standard capable of reaching up to 3MW charging speed. As a core member of CharIN, the leading industry association for developing charging technology standards and EV interoperability, EcoG is working alongside cross-industry stakeholders to build a standard charging connector for commercial vehicles. EcoG has been a driving force in defining the MCS standard that will act as the foundation of this technology. The European Union and US Department of Commerce have also publicly recognized and supported efforts to create an international MCS standard for electric heavy-duty vehicles.
EcoG is pleased to be one of the first companies in the industry to be testing MCS communications interoperability according to the new ISO 15118-20 standard. These tests include multiple projects with the leading charging station manufacturers as well as the premier commercial truck and bus manufacturers. EcoG has engaged with more than 60 component partners, including converter and charging connector manufacturers, to help charging station manufacturers kickstart their MCS charger series launches.
To optimize and improve the robustness of control interfaces, which EcoG has been a market leader in developing, EcoG has collaborated with REMA EV Connections during MCS development and standardization. “We are pleased to have partnered with EcoG on this development work and are excited that the REMA MCS Charging Coupler is integrated into the EcoG MCS reference architecture and the EcoG starter kit” comments Tim Rose, Managing Director of REMA EV Connections.
EcoG simplifies the development of MCS chargers by integrating all necessary components into a tested and interoperable MCS charger interface reference architecture. This allows the truck and bus manufacturers to quickly test their vehicles against the new standard and facilitates the entry of new players into the market. “The collaboration between i-charging and EcoG achieved the remarkable feat of setting up and providing MCS charging solutions interface within just two months.” states Pedro da Silva, CEO of i-charging, and emphasized the significance of this accomplishment, stating, “Lead time to market and adaptability is crucial for us, and the vehicle interoperability is key in the booming market with MCS solutions, for which we are developing a groundbreaking solution targeting MW level charging.”
The Inflation Reduction Act (IRA) is incentivising consumers and businesses to adopt EVs en masse, including through tax benefits, as the US looks to mitigate its largest polluter: transportation. According to The White House, there are three million EVs in the US serviced by only 130k charging stations. Accessible infrastructure including high-powered charging stations will be essential to scaling EVs for commercial and personal use in the US and beyond.
Joerg Heuer, Founder and CEO of EcoG, comments, “The demand for EV charging stations is only increasing as consumers and businesses look to make more environmentally-conscious transport decisions. With the Inflation Reduction Act, the US is looking to lead the way in developing commercial EVs. As the market leader in EV charging reference designs, EcoG is supporting businesses to rapidly step into the market, and build charging stations at scale that will meet the increasing demand for Megawatt Charging Systems necessary for electrified trucks. In the next five years, we’ll see MCS facilitate the electrification of commercial transportation, including city logistics, long haul transport and even maritime applications.”

Recent advances on the cell phone technology has allowed more people to take advantage of the cell phone’s utility even if they are living in remote, far flung area whose network signal reception is weak. Many people who experience low network reception are constantly inconvenienced even in their own home as a weak signal reception vanishes completely when in an enclosed location such as a bathroom or a kitchen. The use of the cell phone booster allows for an increase in cell phone signal even when using it in enclosed locations. With its use, many cell phone users are assured that they will not be missing those important calls anymore. A cell phone signal booster is a simple technological solution to a complex network problem.
The use of the cell phone booster has reduced the number of interrupted calls due to bad network signal. IPod and business phone users can now use their units to their intended use simply because it has been rendered effective by this device. Your cell phone’s battery life is also increased since your unit consumes more energy just by trying to find the right frequency. The cell phone signal booster has made this utility possible.


|Have you ever ridden a wave in the ocean? Ocean waves travel on the surface of the water. You can see them and you can feel them. As you swim through the water, you can even make your own waves.|
Have you ever seen a flag on a windy day? The wind creates waves in the flag. Both the waves in the flag and the ocean waves are waves that you can see. There are other kinds of waves. We cannot see these waves, but we experience them every day. These waves are called electromagnetic waves.
[IMAGE OF ECHO w/Echolocation]
Sound is also a type of wave that we cannot see. Like ocean waves, sound waves something to travel through like waves through the ocean or through a flag. Sound can travel through air because air is made of molecules. These molecules carry the sound waves by bumping into each other, like dominoes knocking each other over. Sound can travel through anything made of molecules – even water! There is no sound in space because there are no molecules there to transmit the sound waves. Electromagnetic waves are different from sound waves because they do not need molecules to travel. This means that electromagnetic waves can travel through air and solid materials – but they can also travel through empty space. This is why astronauts on spacewalks use radios to communicate. Radio waves are one kind of electromagnetic wave.

While computers are fantastic tools, what takes them to the next level is their ability to communicate. By itself, a computer is a fancy typewriter, calculator, and (limited) gaming system. But when we connect computers to other computers, we get the glory and grandeur of the internet!
The word internet is a shortened form of the U.S. Defense Department's internetwork, where inter- means "between." So, our beloved internet means between networks. And it is that magic that happens between all our networks. But part of those networks is our networks. Our phone providers' cellular networks. Our work networks. Our home networks.
Today, we are going to look at our networks and the infrastructure that makes these possible. Since we all use computers, understanding how these devices connect to each other and the internet affects us all. Since you are reading these words, you must be on a network right now. So, let's explore how these words entered into your network and ended up on your screen.
For this journey, we'll start with the modem. Then we'll move on to the router, switch, access point, and (finally) your computer. Of course, we'll touch on all the wires in-between, as well as how data travels wirelessly. We will also explore all-in-one versions and even firewalls. Along the way, you will learn about what you can do to maintain a network properly or even upgrade your network infrastructure.
Before diving into our network infrastructure, let's take a moment to talk about these abstractly. What is a net? No, not The Net, the 1995 Sandra Bullock classic film. A net. Like a fishing net. A net is a collection of interlocking threads, strands, ropes, etc. Together these form a mesh. In the context of the network, the word -work is used like in the phrase "a work of art." Work here means a creation. As such, a network is a mesh-like creation.
That is what computer networks are: They are these net-like structures formed by various wires running between several points. These can be the telephone wires of our DSL provider or the coaxial wires from our cable-internet provider. They can even be fiberoptic lines. And these are just external networks. Our home and business networks are filled with ethernet cables running from one device to the next. This crisscrossing of our patch cables forms the net of our network.
And what is the largest network? The world wide web! And why is it a web? Because it's a network and networks resemble spider-webs. Hence why the bots Google uses to explore and index the internet are called spiders: They crawl all over the web.
But what about that infrastructure part? Infra- means "below," and structure is an organization or construction. As such, the infrastructure is the underlying organization. It is the unseen foundation that allows everything on top of it to function. Think about government infrastructure like roads. This foundation allows us to get to and from our works, homes, store, and more. Furthermore, it facilitates our goods to go from production to the warehouse to the store. Without the foundational support of infrastructure, nothing could go anywhere.
This web-like substructure in our homes and businesses is how our computers connect to one another. It is from this interconnection that something wonderful happens! From this connection, we can shop at Amazon, learn from Wikipedia, and watch videos on YouTube. It's not the devices themselves but the connection between them—much like our brains. As Neuroscientist Kimberley McAllister explains, "That’s because it’s the connections between those cells that make the brain so amazing."
Alright, let's talk about core network components. We'll start with the internet side coming through our internet service provider. And we will finish with the device you are using now to read this now.
The internet enters our residences and businesses via telephone line, coaxial cable, fiberoptic, or something else. Those wires then go to a device that we tend to call a modem. The word modem is an abbreviation of MOdulate DEModulate, the process of converting from digital to analog and back again. As such, we only have an actual modem if we are using telephone-based technologies such as DSL. For coaxial and fiberoptic, what we call a modem is instead a media converter. It takes the digital signal from one medium and transforms it into another.
But for simplicity's sake, let's just call all of these modems. The modem receives the signal from the internet, converts it, and pushes it out to the router.
Router's divide up our networks. Often, a router separates the external wide area network (WAN), the internet, from our internal local area network (LAN). However, it is possible to divide up internal networks into separate LANs using multiple routers. Similarly, the internet itself is divided up into various networks via routers. In all of these cases, because they set the border between two networks, routers have two ports.
Across these networks, routers communicate with one another via internet protocol (IP) packets. Because they use IP addresses, routers operate on the network layer (or layer 3) of the Open Systems Interconnection (OSI) model. These packets have both a receiver and a sender's IP address. These addresses tell all the routers along the way where a packet is coming from and where it is trying to go. Routers know where to send these packets by using routing tables.
The routers on the internet use public IP addresses to send information, while our private networks use private IP addresses. As such, one of the coolest tricks a router can do is to convert a public address to a private one and vice versa. Once converted, the router can then pass this information off to a switch.
Switches (and Hubs)
While a router has two ports, a switch often has four, eight, 16, 24, or more. It is common to find one or more 48-port switches in many businesses—and all of these ports are in use! Regardless of the number of ports, a switch creates links between devices on the network. For example, one workstation sends an email, which the switch will route to the router. The switch directs another workstation to the server to access a shared file. The switch creates a link between a third workstation and the network printer to print off a document. All at the same time. A 48-port switch could simultaneously make 24 connections between 48 different devices. And when one device needs to switch to another, the switch switches the connection.
Switches function like telephone operators. They create links between different devices and then create new links between other devices. In this way, any device on a network can communicate with any other device on the same network. While routers use IP addresses, switches know which device is which because of their media access control (MAC) address. Since they use MAC addresses, switches operate on the data link layer (layer 2) of the OSI model. Once they have switched to the right device, the switch forwards the signal down patch cables to its destination.
Before we had switches that could intelligently direct signals, we had hubs. Hubs didn't care about MAC addresses. Instead, they took a signal in and then rebroadcast it to every port. Every device connected to the hub gets the signal, but unless it is directed to this device, they ignore it. As such, with a hub, there could only be one message at a time. The message comes in one port and is rebroadcast to every port. The next message comes in and goes to every port. So, while a switch can have any number of ports, a hub would just be more and more bogged down with every additional port.
Patch Cables and Patch Panels
The net part of our internal network is overwhelmingly made up of patch cables. Most patch cables are made up of four sets of twisted-pair copper wires. Sometimes these twisted pairs are shielded from magnetic interference (STP). More often though, they left unshielded because of the cost (UTP). These are then numerically rated based on their technological capabilities, from 5 (or lower) to 8 (or higher).
Our homes may have only a few of these wires. However, our works are often overflowing with them. The plug, known as an RJ45 port, looks like (and is) a fat phone jack. The modem has one of these RJ45 ports, which is connected to one of the two RJ45 ports on the router. The router's other RJ45 connects to one of the switches via another patch cable. And then several or even dozens of patch cables explode out of every RJ45 port on the switch.
To bring some semblance of organization to all these wires, the ports on the switch are often connected to a patch panel. Attaching patch cables to a patch panel is a relatively easy task. And then, patch cables of any length can be run throughout the ceiling, floors, and walls. These will then often wind up terminating at a wall plug throughout the building. It is from here, that we will plug in our computers, VOIP phones, printers, access points, etc. Because they connect physically everything, patch cables are on the physical layer (layer 1) of the OSI model. If your computer is hardwired to the internet, then these words have traveled this path to your screen.
While it is possible to have an entirely wired network, many of us like the convivence of wireless technology. Like a modem converting from one medium to another, an access point (AP) converts from copper wires to radio waves. The signal comes in via the patch cables and is then broadcast to nearby wireless computers, tablets, smartphones, etc.
Unlike a switch, which knows what device should be receiving a message, APs are more like hubs. They simply send the signal out to everything. And like a hub, each device receives all the signals, but just ignores anything not addressed to it.
You may recognize most or all of these devices from your work. However, many of you might be saying that you don't have most of these at home. Instead, you have a router. To you, I say, your "router" is much more than a router. Like a modem (which is rarely actually a modem), a router is only a router if it has two ports. Any more, and it's a router/switch. And if it has built-in WIFI, it's a router/switch/AP.
These all-in-one devices can be fantastic. They do it all. But they do it all, so you can't upgrade them. You can't add more ports to this device. And if the built-in AP is using an old wireless standard, you aren't going to be able to make it new.
That said, it doesn't matter. The great thing about networks is that they are expandable. If you have even a single port, you can add a switch to it. And you can add a switch to that switch. I've gone into businesses where they have racks with three 48-port switches. Remember that each of these has to end up at the singular router port, so one switch plugs into another. And you know what's really cool about switches? They're intelligent! You can plug anything into any port on any switch and it will just know what it is. So yes, a switch knows when it is plugged into another switch and will behave accordingly. (Just don't be tempted to plug in two or more ports from one switch into another unless you turn on spanning tree protocol.)
Now, let's say you want to upgrade your AP, just add another AP to your switch. Done. Not only does this work for upgrading the wireless technologies that are available to your network, but this also works when you want to increase the coverage to your home network. Is WIFI not great in a part of your space? Just run some patch cable out toward that area and place an AP nearby, preferably attached to the ceiling.
If you have to set up two APs though, take the time to ensure that they are not interfering with one another. WIFI is broadcast over radio waves. So, if two or more devices try to use the same or similar channels, they will both interfere with one another. This issue isn't a big deal in the 5.0 GHz range but can be a real problem with 2.4 GHz. By the way, this is also true if you live in a place with multiple competing wireless networks, such as apartments or condos. If you live in such a place, you need to get ahold of a wireless spectrum analyzer and see which channels are being used the most.
And on the off chance you are still using a hub, you've got to replace that with a switch now.
We spend so much of our time trying to fortify our computers. However, we often forget to protect our network infrastructure. While our systems are set up to not trust anything outside, they blindly trust everything on our private network. So, if any element of our network is compromised, everything in our network is compromised.
As such, here are some ways to secure our network infrastructure:
For those wanting to dive deeper into networking infrastructure, there are many opportunities to learn more.
Network infrastructure is composed of the same elements. Information comes in from the internet comes into our house or business via a modem. This information crosses from one network to another via a router. It then travels over a switch toward a particular endpoint. And if the endpoint is using WIFI, the information will head out via an AP. At our work, each of these steps will be through distinct devices. At our homes, some or all of these might be combined into one device.
Knowing this, you are now armed with ways to improve both the quality and security of your network. Whether it is your home or business, you know how to recognize what you have. Furthermore, you should have some ideas on where you'd like to go next.
And if you want some help with your journey into a network that is better, stronger, faster, we're here for you.

 Some devices are referred to as a Layer 3 switch because they function on both the network and data link layers of the OSI model. However, this is really a misnomer. As James "Professor" Messer explains, inside these devices are separate routers and switches that are combined in the same chassis. As we'll talk about later, it's possible to have one device that combines these with a modem and AP, and more.


One of the most frustrating issue with remote work is when the internet connection is stopping you from working.
It’s an important issue for those who use a lot of video conferencing.
For example, you are giving online singing classes via skype and you or your student are experiencing the following voice or video problems :
- Voice or video is shredded or frozen for a long time
- Voice or video is in a very poor quality
Eventually, you and your caller end up exchanging back and forward the same question “can you hear me ?” and you are not able to continue your work.
What is happening ?
There are two main internet quality indicators that you can check to see if the internet connection is a problem:
- Internet speed is how fast the data travels between your computer and the internet. You need faster internet if you want to send and receive high quality video (high volume video or large video).
- Internet connection consistency is how many errors the data encounters along the way through the internet. Its often called PING. Internet data is carried around in small chunks called packets and your connection could be experiencing packet loss. Packet loss causes a decrease in audio/video quality.
Test your internet quality (TEST #1)
To check your internet quality you can go to https://www.speedtest.net/ and make a test of your internet connection. Let me give you an example with a test that I’ve conducted with a public Wi-Fi hotspot.
How to interpret the results :
PING. The lower the better. Since it means how many errors the data encounters along the way going from your computer to the internet and back, its better to have fewer errors.
From my experience, I start to experience some voice and video conference problems from PING around 20 (on my or my caller computer).
DOWNLOAD internet speed. The higher the better. It means how fast the data travels from internet to your computer. For example. Higher the speed, better the video and voice quality you can receive in your video call meetings. UPLOAD internet speed. The higher the better. It means how fast the data travels from your computer to the internet. For example. Higher the speed, better the video and voice quality you can send in your video call meetings.
From my experience, I start to experience some voice and video conference problems below 2 Mbps download / 1.5 Mbps upload.
It is important to test the internet quality on both ends of the connection (yours and your caller). So if you encounter any issues, conduct the test on your computer and your caller computer and compare the results.
Internet stability is key => TEST #2
I highly recommend conducting another test which will help you to understand how you PING is stable in time. You can do it using https://ping.canbeuseful.com/.
In this way you can see that my PING went very high during a couple of seconds and that is why my video conference call was not working. I usually conduct this test on my computer and ask my callers to do this test to check if the problem is coming from their side.
What can you do to make it better ?
Below you will find a list of tips of what you could try to do for you and your caller internet connection problems :
- Close other applications that use the internet, especially those playing music or video
- Cancel any internet file transfers in progress
- Disconnect other devices using your internet connection (your neighbor or coworkers are connected to the same internet connection)
- Reset your modem and router. Unplug your modem/router. Wait about 10 seconds, plug in the modem/router
- Reduce the quality of the video that you are sending via the video conference application (in Facebook video call service you have this option)
- Be closer to your Wi-Fi modem/router. Sometimes when your modem/router is far in the office/apartment the signal is weak. Especially when the signal is going through walls.
- Turn of the video in your conference call
- Try to use another internet connection (ex. try to make a hotspot from your mobile phone if your 4G or 3G is better than your current connection)
- Check your computer for virus that slower down your internet connection


The prime aim for sound attenuation in HVAC systems and equipment is to ensure that the acoustical environment in a given confined space is maintained. Sound is created by a source, transmitted along one or more paths, and eventually reaches a receiver. Treatments and modifications can be applied to some or all of these elements to achieve an acceptable acoustical ambiance, although it is usually the most effective and least expensive method to attenuate noise at the source.
In HVAC systems, the source of sound is mainly associated with the building, mechanical and electrical equipment. Sound sources are the components that either intrinsically generate noise as in electric motors, or when air passes through them, like dampers or diffusers. Sound receivers are generally the occupants of the building. The noise control engineers are most often constrained to modify the sound transmission paths as a means of achieving the desired sound levels in those areas of a building which are inhibited. As a preliminary approach to control noise it is well worth to examine the source of noise, the sound transmissions path and the receivers.
The noise control is achieved by means of selective sound absorbing material by absorption course. Silencers or attenuators used in HVAC installation are for treating air borne noise. For better attenuations in mid and high frequency range (0.5 kHz – 8 kHz) sound attenuators are to be in absorptive type design. The acoustic energy propagating through the silencer is effectively absorbed by the fibrous absorption material and converted into heat energy.
The selection shall be on the basis of maximum allowable pressure drop at rated flow and the silencing
criteria. Flow area throughout a silencer must be sufficient to accommodate the air flow without imposing excessive restriction. Efforts to controls noise and vibration in a wide range of mechanism and devices inevitably require the use of passive acoustical materials. It not only requires the right choice of materials but also understanding the properties of the how acoustical materials work, their installation procedure and most appropriate location to install them which in turn is vital to achieve the greatest performance.
