The Wireless Broadband Alliance (WBA) today invited all organisations in the Wi-Fi ecosystem to join WBA OpenRoaming and become part of a globally available Wi-Fi federation that offers an automatic and secure connection of billions of devices to millions of Wi-Fi networks. WBA OpenRoaming provides a new global standards-led approach, removing public-guest Wi-Fi connectivity barriers […]
The microstrip antenna, Part 1: Basics
The microstrip antenna is a convenient, planar, easy-to-fabricate antenna with some attractive attributes and features, as well as some distinct limitations. The passive antenna is a critical part of any wireless communications link, for both transmit and receive sides. Depending on the application, the same antenna may be used for both roles, or radically different […]
SDK adds accurate distance measurement capabilities to BLE SoCs for covid distancing needs
Dialog Semiconductor plc announced a new Wireless Ranging (WiRa) Software Development Kit (SDK) that adds highly accurate and reliable distance measurement capabilities to its DA1469x family of BLE SoCs. The need for more accurate and reliable distance measurement and tracing technology has become even more critical in the wake of COVID-19. With businesses across the […]
LoRaWAN smart vibration sensor address industrial automation applications
The development of smart manufacturing relies on sensors, which acquire data, which automate the manufacturing process and thereby enable predictive maintenance. To meet the future needs of the industrial automation market in North America, Europe, Japan, and Southeast Asia, Advantech has collaborated with global semiconductor solutions provider Semtech to launch a LoRaWAN smart vibration sensor. […]
Quad-channel, wideband RF transceiver handles 3G/4G/5G macrocell base stations, M-MIMO, small cell system apps
ADI has announced a new member of our industry-leading RadioVerse family, the ADRV9026 quad-channel, wideband RF transceiver. Designed to support base station applications (including single and multistandard 3G/4G/5G macrocell base stations, massive MIMO (M-MIMO), and small cell systems) this wideband RF transceiver offers quad-channel integration with the lowest power, smallest size, common-platform solution. The highly…
Economical vector signal generator features 40 MHz bandwidth
The VSG60A vector signal generator offers the performance and agility of a serious vector signal generator at a fraction of the cost. A low phase noise, agile local oscillator with a 200 μsec switch time enables frequency hopping spread spectrum testing, and a dual 14-bit DAC runs at 2x or 3x the I/Q symbol rate […]
e-Book: Wireless and Wearables
by David Somo, ON Semiconductor It may seem far-fetched to suggest that “Star Trek fashion” will be in style with people walking around wearing amped-up watches, eyeglasses, rings and bracelets. But then again, years ago it seemed futuristic to think that people would use their smartphone to email, surf the web, play games, watch videos, […]
MEMS chip combines accelerometer with high-accuracy temperature sensor
The STMicroelectronics LIS2DTW12 combines a MEMS 3-axis accelerometer and a temperature sensor on a single die for use in space-constrained and battery-sensitive detectors such as shipping trackers, wearables, and IoT endpoints. The sensing accuracy of 0.8°C offers precision comparable with stand-alone standard temperature sensors. In addition to enhanced temperature compensation, leveraging the sensor’s superior accuracy, the accelerometer […]
Understanding wireless across the spectrum
Waves are part of our world as both waves in the ocean and radio waves coming in from the Sun’s corona share fundamental properties.[i] Wireless communication was born from the science of waves and how they travel. After more than a hundred years of study, we’ve organized waves into a large electromagnetic spectrum (EM) that […]
RF-sampling transceivers enable multiantenna wideband systems
Texas Instruments has introduced two new RF-sampling transceivers that are the first in the industry to integrate four analog-to-digital converters (ADCs) and four digital-to-analog converters (DACs) in a single chip. With the industry’s widest frequency range, highest instantaneous bandwidth and 75 percent smaller design footprint than a discrete solution, the quad-channel AFE7444 and dual-channel AFE7422 […]
