Sensing City Strategies and Versa’s VX-VEB160G4 (V2) 300Mbps Ethernet Extender Kit

Memory fails as to who actually coined the phrase, but living in a smart home will eventually feel like living inside of a robot. The flow of life, work, and travel will become so tailored that we might begin to wonder how those who lived in earlier times survived. Imagine how much easier life would have been for Ben Franklin. “Alexa, dost thou know when thunder and lightning will overflow the skies?” “Okay, Ben,” Alexa replieth, “There’s a seventy percent chance of rain this afternoon.” “I thank thee.” “You’re welcome.” But, I digress. As our homes, workplaces, and cities become increasingly connected and smart, what technology will innovators rely on to drive this transformation? The answer is sensors. The “linchpin” to these “self aware” environments will definitely be the sensor. These devices will read our reality and supply billions of data points to super computers for analysis to help developers innovate. It’s going to be interesting to watch. Many of us have witnessed this phenomenon on our roadways. Street lights adjust to the flow of traffic. An announcement of an accident appears on a roadside marquee redirecting motorists to the fastest alternate route to their destination.Sidewalk Labs - Quayside Tech giants like Alphabet Sidewalk Labs have witnessed this. The Google parent company is tapping into sensors to find ways to improve city life. The team is immersed in a 12-block test project along the waterfront in the city of Toronto in Canada, to see how a sensing city can inform design and accessibility for the citizens there. The waterfront or Quayside project is going to be built from the ground up. Installers don’t always have that luxury. So how do organizations and cities “back-fill” getting sensing devices into the odd places they’re needed to collect data?

Solving the Problem of Remote Sensors

As an IT networking pro easing your way into the Internet of Things (IoT), you’re probably thinking about practical and effective ways you and your team will be installing sensors.
  • Around a client’s home
  • In an office or government building
  • On a college campus
  • Across municipal infrastructure like atop a bridge or cell tower
Whenever a remote installation is required, Ethernet extenders are able to provide a simple, one-cable solution.
Versa's VX-VEB160G4 (V2) is an Industrial, wall mounted, 300Mbps Ethernet Extender Kit. It’s our best in class, providing data rates of 190 Mbps downstream and 110 Mbps upstream via legacy copper lines.

What Is An Ethernet Extender?

Also known as a repeater, an Ethernet extender is an IEEE 802.3 compliant device that allows a connection to a local area network (LAN) that is beyond the standard cable distance of 100 meters [330 feet], the distance that data can travel over copper. An Ethernet extender is commonly used to connect remote devices, such as, CCTV cameras, sensors, wireless access points (WAPs), display screens, point of sales kiosks, and security access technologies like retinal scanners or badge readers. Ethernet extenders are used for copper Ethernet cabling solutions like twisted pair and 4-wire options. They help connect devices that would otherwise access a wireless area network (WAN) but do not have a clear sight line (wireless signal path).

Our Extender, The VX-VEB160G4 (V2)

The VX-VEB160G4 (V2) is a best in class PoE compliant device with the fastest speeds for this type of device anywhere. It can be deployed at distances of up to 9,000 feet (2,743.2 meters). It’s the perfect option to implement a remote sensor in a variety of settings and can weather temperature extremes between -40°C/F to 75°C (167°F). Essentially, the VX-VEB160G4 (V2) is a perfect option for that remote sensing device indoor or out, that needs to deliver data and power over one single legacy copper cable.

Where Sensing City Sensors Will Be Deployed

Smart cities and sensing cities are in varying degrees of development around the globe. Toronto isn’t the only place a sensing city is being implemented. Christchurch in New Zealand is another project. Sensing cities monitor flows of people, traffic, quality of water and other essential services. Some of the ways that sensors are collecting data are listed.
  • Electrical grid management
  • Smart parking facilities
  • Public safety management
  • Water quality management
  • Electric vehicle charging stations
  • Real-time scheduling and tracking of local transportation
  • Public information access points
  • Air quality control
  • Noise reduction management
All of these factors will be monitored and managed to make quality of life better for residents.

Sensing City Dashboard Simulation

To give you an idea of how this might be communicated to decision makers, here’s a sensing city dashboard simulation developed by MIT Portugal that shows an overhead grid and power consumption levels within different sectors of a city. Power consumption spikes indicate the presence of a local event or it could be an alert that informs authorities of infrastructure problems. This could save time and considerable amounts of money as it not only identifies location but could also diagnose problems and remove delays and guesswork as to the proper resolution.

Development in Toronto

Developmental Sequence for the Alphabet project in Toronto. Not surprisingly, infrastructure is the first layer of this project. You have to have the bones to support all of the services.

Quayside Sensing City Sidewalk labwSmart, Slow Development Over Time

It’s probably not realistic to think that a project like building a sensing city from the ground up has an end date. It’s just one of those things in life that will continue to evolve as needs become apparent and technology is developed. One of the reasons Rohit Aggarwala, the project lead for Alphabet Sidewalk Labs, is calling the Quayside a sensing city is that he feels the term “smart city” is obsolete. The term smart city is too closely associated with software products focused on wringing maximum efficiency out of cash-strapped city services. Makes sense. Sensing brings with it the idea that conclusions that are drawn and implemented in design will be based on empirical data from the sensors. It will remove human bias based on pre-conceived notions and stay true to fact.

Powered Fiber Cable Systems

Exploring Powered Fiber Cable Systems (PFCS)— Is it time for PoE to Divorce Power and Data?

Power over Ethernet (PoE) is known for its simultaneous transmission of power and data using twisted pair copper, but will the search for faster speed rates influence the separation of data and power? New Powered Fiber Cable System (PFCS) solutions introduce a new breed of PoE extension. The solution utilizes a powered fiber cable that insulates fiber and copper separately and assigns copper with one sole purpose—to transmit power.

Understanding PoE's 100 Meter Limitation

Each new 802.3 PoE standard tends to introduce higher power outputs. IEEE’s initial 802.3af PoE standard introduced compliance for 15 watts of power (12.95 with power dissipation). The standard was followed by 802.3at, also known as PoE+, and introduced compliance for 30 watts of power (25.4 watts of power). IEEE is currently studying 802.3bt, also known as PoE ++, a new standard that aims to provide up to 80 watts of power by using all four twisted copper pairs to transmit data and power. But though new standards seem to be improving upon output power, each new standard fails to improve the maximum supported distance of 100 meters—the standard Ethernet limitation. Receive a Complementary Consultation   Copper has the ability to transmit power to longer distances; however, the range of PoE is limited by copper’s inability to transmit data to ranges that exceed 100 meters. Optical fiber can transmit up to 100 Terabits per seconds.  Copper cables are able to transmit gigabit speeds and up to 10 Gbps with newer networking cables such as Cat6 and Cat7.  For the time being, 10 Gbps transfer speeds are sufficient for even the most data-hungry Internet users. Nonetheless, optical fiber easily surpasses 100 meter distances. Fiber cable systems with new powered fiber cables can achieve up to 3,000 meters.

Approximating Power over Fiber

Commscope has designed a new powered fiber cable that insulates the optical fiber cable and copper wire within their own separate jackets. The new design deviates from traditional hybrid optical fiber cables that insulate both types of mediums within the same jacket. Network installers can easily peel the cables apart for quick access. The new cabling requires no other special tools besides a wire stripper. These new types of powered fiber cables are quite flexible in comparison to traditional hybrid fiber cables. powered fiber cable system Though the solution can’t exactly be described as Power over Fiber, the optical fiber and copper cabling run alongside each other and leverages the same benefit that PoE provides—the ability to deploy powered devices at any location without having to rely on local power supplies. The ability to install devices without relying on local power supplies, along with its simple ‘plug-and-play’ installation, makes PoE an essential component of networking topologies. But PoE faces a standard 100 meter limitation which forces network administrators to rely on additional equipment such as PoE extenders and media converters to extend network connections beyond Ethernet’s standard 100 meter limitation. This new breed of PoE extenders will eliminate the need for additional extender kits and simplify network connections.

Leveraging the Power of Copper and Fiber—Separately

Electrical Engineer Bill Schweber observes that the effectiveness of powered fiber systems stems from separating optical fiber and copper. He remarks that the simultaneous transmission of power and data in standard networking cables “require significant "negotiation" and confirmation between the source and load, between intervening ICs and, in order to assure that power is available and acceptable by a peripheral, that there are no conflicts in hardware or software.” Powered fiber cable systems eliminate power negotiations and reserves optical fiber for data transmission and copper wiring for power transmission. The electrical engineer comments that “PFCS [Powered Fiber Cable Systems] seems to me to be a clever scheme, since it leverages the advantages of each medium (optical+copper, PoE) without either one getting in the way of the other one, and the associated complexity.” Schweber concludes “that by using the long run of copper just for power and not for data, the technical difficulties will be reduced while the performance will be more consistent and easier to manage”. Separating data and power allows copper to deliver power output ranges that exceed the current 802.3at standard of 30 watts. And optical fiber speeds will be able to deliver transmission speeds that surpass 10Gbps to future powered devices.

Additional Benefits of Powered Fiber Cable Systems

powered-fiber-cable-systems-use-cases-compressor According to Aruba Networks, Powered Fiber Cable Systems “Greatly speed up planning by eliminating DC electrical calculations for voltage/power drop over varying distances”. These devices can support up to 32 devices from a centrally located USPs. Powered Fiber Cable Systems essentially operate similar to long extension cords. It’s highly unlikely that IEEE will divorce Power from Data when it comes to PoE. PoE is ideal for home and enterprise networks, even with a 100 meter Ethernet limitation. And in the cases where powered devices need to be installed beyond 100 meters, there are a myriad of PoE extender options such as fiber media extenders, UTP Ethernet Extenders, and coaxial cable extenders for example, that effectively bypass the limited distance and preserve speed.
