Way Beyond Wireless: Planning for 5G

By on • ( Leave a comment )

5G enabled devices in the IoT will allow huge numbers of sensors and devices to gather incredible amounts of data and transmit the data at remarkable speeds over wide distances. We are going to see a new wave of information enabled in government and industry. Instead of your phone or laptop acting as the processor, it will sit inside the edge of the 5G infrastructure. This will allow things like driverless vehicles and telemedicine.5G will provide the digital infrastructure that will shape the quality of life of most of the earth’s population. Yes, it will load web pages and play videos on your phone 10 to 20 times faster than 4G. Mobile devices will spend less time processing data, which will consume less power, which will result in extended battery life. But these are little advances compared to what is possible.

Fiber. Great In Your Diet. Costly In Your Data Center

Let’s say you’re in charge of a data center and your boss reminds you that streaming video and IoT devices are all the rage and if you don’t keep up with bandwidth demand, you’re toast. You have 10G links that use 10G SFP+ SR transceivers at the aggregation layer. You upgrade your switches or linecards to ones that have 40G QSFP ports like the Nexus series switches.You now have a couple of choices for the QSFP ports: You could use QSFP SR4 transceivers, which requires ribbon fiber. That means you’d have to install more trunk fiber and modify patch panels to handle the MPO (Multi-Fiber Push On) connectors. Or you could use the QSFP BiDi transceiver, which, by the way, costs less than the SR4 transceiver. All you have to do is unplug the dual fiber MMF (Multi-Mode Fiber) cable that you already have in place, and plug it right into the BiDi. No hassle. Boss happy. Seems obvious, doesn’t it?

The Internet of the Future – What Happens Behind the Scenes?

By on • ( Leave a comment )

The Internet of Things (IoT) is at the beginning of its golden age. Forecasts note that the number of connected devices could exceed the 20-billion mark by next year and could reach 50 billion by 2022. For all this, we are basically using just one network protocol. The still-dominant IPv4 standard uses 32-bit addresses, only making around 232, or 4.3 billion different addresses possible. Luckily, a new 128-bit format has existed in principle since 1998. This IPv6 standard offers an address space of 2128, or around 340 sextillions, eliminating any concerns. However, DE-CIX measurements show that currently, only around 5 percent of traffic corresponds to the new standard.

Cybersecurity’s Path in the Future of BACnet

No system out there is impenetrable. But BACnet, an ANSI/ASHRAE and global ISO standard that covers a rage of IoT, IP and operational technology devices, is exploitable. The more than 25 million BACnet devices — which include HVAC, lighting controls, ACS, mart meters, elevator controls, UPS and other building automation systems — are easy points of entry even for a novice hacker.

Belden’s Digital Electricity Cables reach distances and wattages that PoE can’t

By on • ( Leave a comment )

Belden’s Digital Electricity Cables are available in copper for power-only applications, and in hybrid copper/fiber constructions to transmit power and data over long distances in a single cable run.
The transmit up to 20 times more power or 20 times more distance than PoE: up to 2,000W or up to 2km reach in indoor and outdoor applications. Digital Electricity Cables support Internet of Things (IoT) and convergence in venues such as airport terminals, convention centers, hospitals, high-rise hotels, stadiums and office towers.

University of Washington units share three-year NSF grant to make ‘internet of things’ more secure

By on • ( Leave a comment )

Several University of Washington schools and offices will team up to research how organizational practices can affect the interagency collaboration needed to keep the “internet of things” — and institutional systems — safe and secure. Devices connected to the internet of things, now becoming standard components in new buildings, can increase energy performance while reducing costs. But such highly connected sensors can also bring potential security vulnerabilities.

Luminescence Thermometry on the Route of the Mobile‐Based Internet of Things (IoT): How Smart QR Codes Make It Real

By on • ( Leave a comment )

Quick Response (QR) codes are a gateway to the Internet of things (IoT) due to the growing use of smartphones/mobile devices and its properties like fast and easy reading, capacity to store more information than that found in conventional codes, and versatility associated to the rapid and simplified access to information.
