The LoRa Alliance announced that LoRaWAN now seamlessly supports Internet Protocol version 6 (IPv6) from end to end. By expanding the breadth of device-to-application solutions with IPv6, LoRaWAN’s addressable IoT market is also broadened to include internet-based standards required in smart electricity metering and new applications in smart buildings, industries, logistics, and homes. The new IPv6 adaptation […]

How many types of radar are there?
Radio detection and ranging (radar) uses reflected radio waves to detect and determine the distance, angle, and velocity of objects relative to the radar system. A basic radar system consists of a transmitter producing electromagnetic waves in the radio or microwave spectrum (these can be pulsed or continuous), a transmitting antenna, a receiving antenna (often […]
What is characteristic impedance?
We speak of 50- or 75-Ω coaxial cable. The novice wonders if these numbers apply to a given length, say 100 ft. Could you connect an ohmmeter to one end of the cable and expect to get that reading with or without the conductors shunted at the far end? The answer is absolutely not. The characteristic impedance […]
Wireless modules support two or three radios
The MAYA-W2 series from u-blox provide wireless connectivity with Wi-Fi 6, Bluetooth LE, and 802.15.4 radios.
Trace/debugger helps analyzer high-speed Wi-Fi streams
Clarinox Technologies announced the addition of ClariFi Insight, a non-intrusive trace, and debugger that enables customers to debug their systems that including ClarinoxWiFi or ClarinoxBlue. ClariFi Insight traces the behavior of a system, enabling developers to more easily identify and correct errant application behavior by capturing high-speed events. This has been successfully tested at speeds […]
MOSFETS feature low on resistance for high power density
STMicroelectronics’ STPOWER MDmesh M9 and DM9 N-channel super-junction multi-drain silicon power MOSFETs are ideal for switched-mode power supplies (SMPS) in applications from data-center servers and 5G infrastructure to flat-panel televisions. The first devices to be launched are the 650V STP65N045M9 and the 600V STP60N043DM9. Both have very low on-resistance (RDS(on)) per unit area, which maximizes power density and permits compact system dimensions. Each has the […]
What is “orthogonal”? (Part 1): mechanical design
The phrase and concept “orthogonal” is widely used in engineering, but it is also often misunderstood. I was chatting the other day with a non-technical friend and said something like, “Oh, that won’t happen. Those two things are orthogonal.” My friend looked at me and replied with a “huh?” and he was right to do […]
Omni outdoor antennas cover 5G low bands
Fairview Microwave Inc. has just released a new series of 5G outdoor-rated omnidirectional antennas that cover 4G, 5G, LTE, and CBRS bands. These small form factor omni antennas are the perfect solution when broad coverage is required but traditional base station antennas are too bulky or expensive. They support 6, 7, 8, and 10 dBi…
Small dual-band antenna for IoT optimized for 868 MHz and 915 MHz
Antenova Ltd launches a new low-profile antenna displaying strong performance on both Europe’s 868 MHz bands and the US 915 MHz bands. The new antenna is named ‘Lama’, part number SRFI065. It was developed for small connected devices operating on the LP-WAN networks including LoRa, Sigfox, Wi-SUN, and MIoTy. This antenna uses the ISM frequencies […]
Brooklyn 6G: Sustainability is the goal
NYU brought its wireless symposium back to life, now called Brooklyn 6G. This 2½ hour virtual symposium focused on sustainability as the most important topic in next-generation networks.
