Wi-Fi 7 Moves Forward, Adding Yet Another Protocol
By Karen Heyman - 17 Jul, 2023 - Comments: 1

The latest generation Wi-Fi protocol brings better speeds and data handling, but it does little to bridge various communications technologies. That, in turn, makes it more difficult and more expensive to design chips because they must integrate and support multiple wireless technologies, including different versions of the same technology. Wireless communications technologies are often victi... » read more

What’s Next In Wireless Standard Adoption?
By Chen Chang - 27 Apr, 2023 - Comments: 0

By Chen Chang and Alejandro Escobar Calderon Although each generation in wireless technologies often introduces enhanced capabilities, the broad adoption of any new technology requires both technical and business viability. For 5G, solving for technical challenges such as path loss and radio front-end efficiency has led to massive innovations in network design, semiconductor packaging, and t... » read more

Test Gets Ready For Wi-Fi 7
By Jan Ermert - 07 Mar, 2023 - Comments: 0

New test solutions are emerging to address the test challenges associated with the forthcoming Wi-Fi 7 standard. Wi-Fi 7 covers the (so far, for Wi-Fi) unused frequency range between 6 GHz and 7.125 GHz, using up to 4096-QAM modulation schemes and up to 320MHz channel bandwidth (see figure 1). Fig. 1: Wi-Fi band ranges are shown here, including the 3x increase in bandwidth enabled by a... » read more

The Future Of Connectivity Is Higher Data Rates And Micro-Positioning
By David Vondran - 11 Oct, 2022 - Comments: 0

These days, we tend to take global wireless connectivity for granted. Whether we’re in a coffee shop, a hotel room, or a plane at 35,000 feet, chances are that we’ll be able to enjoy Internet access at reasonable speeds. But despite this constant connectedness, we still manage to misplace our keys and forget where we left our smartphones. New connectivity technologies are promising to ha... » read more

What follows are excerpts of that conversation. SE: Renesas has acquired a number of companies over the past several years. What's the goal? Chittipeddi: The goal very simply is to create an industry leading solutio... » read more

Our Wireless World: How Wi-Fi 6 Will Seamlessly Integrate With 5G To Help Keep Us Connected
By David Haynes - 19 May, 2022 - Comments: 0

Most of us have a good understanding of what 5G is by now. Buzz around the fifth-generation wireless technology has reached a fever pitch – and for good reason.  It offers significantly greater bandwidth, faster connectivity, and lower latency, enabling it to power a much broader range of digital applications than its predecessors. 5G is ushering in a new wave of business and societal trans... » read more

Securing Short-Range Communications
By John Koon - 15 Dec, 2021 - Comments: 0

Short-range wireless communication technology is in widespread use and growing rapidly, adding conveniences for consumers while also opening the door to a whole range of cyberattacks. This technology is common across a variety of applications, from wireless key fobs to unlock a car and start the ignition, to tags used to help drivers find misplaced items such as car keys. RFID also is starti... » read more

Grappling With Smart City Security Issues
By John Koon - 02 Sep, 2021 - Comments: 0

Security concerns are rising as cities seek to modernize services by connecting them to the internet and to each other, creating a widening attack surface that is a potential target for everything from disruption of services to ransomware demands. The goal of smart cities is to apply technology and intelligence to a variety of services to enable independent operation, real-time response, as ... » read more

Securing 5G And IoT With Fuzzing
By Synopsys - 04 Aug, 2021 - Comments: 0

5G will revolutionize many industries, with up to 100 times the speed, 100 times the capacity, and one-tenth the latency compared to 4G LTE. But in addition to providing superior performance, 5G expands the attack surface of apps and IoT devices that rely on this next-gen network. In addition to known security exploits, we’re bound to see unknown, novelty attacks. Fuzz testing (or fuzzing)... » read more

Electrically connected spin-torque oscillators array for 2.4 GHz WiFi band transmission and energy harvesting
By Technical Paper Link - 27 Jul, 2021 - Comments: 0

Researchers at the National University of Singapore and Tohoku University developed a device that uses spin-torque oscillators (STOs) to harvest energy from 2.4GHz Wi-Fi signals and wirelessly power an LED without need for a battery.   Technical Paper Link: Abstract "The mutual synchronization of spin-torque oscillators (STOs) is critical for communication, energy harvesting ... » read more
