Mikroe has introduced a narrowband LTE IoT communication development board in its ‘Click’ format. It is called ‘NB IoT 6 Click’, and its active wireless module is the BC65 from Shanghai based Quectel, a low-power (4μA) device compliant with 3GPP Release 13 and Release 14, supporting LTE bands B1, B3, B5, B8, B20 and B28 across 700MHz to 2.2GHz. LTE ...

Antenova has created a PCB antenna for 5G comms that includes band 71 (617 – 698MHz) for T-Mobile in the USA. “SR4L104 is future-proofed as it covers the most common current 4G & 5G bands globally, ranging from 617 to 7,125MHz frequency, including the new 5G bands,” said the company. It will “bridge 4G/LTE networks as 5G becomes the new global ...

Leankon has announced a 40 x 5 x 1mm surface-mount antenna intended to support 4G LTE and GNSS globally. Called LK1830201, it covers three bands simultaneously through a single 50Ω port: 698 – 960MHz: <-6dB return loss, <3 VSWR, >60% av efficiency, 1.4 dBi peak gain 1,710 – 2,690MHz: <-7dB return loss, <2.6 VSWR, >65% av efficiency, 3.5dBi peak gain ...

Siglent has created a multi-instrument mobile 5G signal analyser for 5G NR/LTE with 9kHz to 7.5GHz range and 110MHz real-time analysis bandwidth. “Combining spectrum analysis, vector network analysis, cable testing and antenna testing into a single portable platform, the SHA860A delivers versatility for base station deployment, maintenance, and on-site troubleshooting,” according to the company. Its 5G NR over-the-air mode demodulates ...

Mikroe has introduced a dual-mode LTE-M and NB-IoT tranceiver in its ‘Click’ board circuit prototyping format. Called ‘LTE IoT 10 Click’, it is built around Sequans’ Monarch GM02S IC, which supports global 617MHz to 2.2GHz operation. The board is 3GPP LTE Release 14 compliant, and can be upgraded to Release 17, according to Mikroe. Transmission is at up to +23dBm, ...

Digi International and SparkFun Electronics have designed a development board that adds peripherals around a socket for Digi’s XBee wireless modules. Called ‘SparkFun Digi XBee development board’, it is designed for prototyping cellular IoT applications using one of several Digi’s XBee wireless modules – the socket footprint is Digi’s 13 x 19mm XBee 3 micro form factor – in particular ...

U-blox is sampling a module that combine LTE-M cellular communication (23dBm output) and GNSS for precise location finding. SARA-R520M10 is the super-set device, combining on-board an LTE-M and NB-IoT IC (v2 of UBX-R5) with the company’s M10 GNSS receiver IC, allowing concurrent communication and location-finding in a 16 x 26 x 2.2mm package. Cellular coverage is global, and the module ...

A tethered drone has been used to demonstrate a pop-up large area private 4G LTE cellular network. “This allows the drone to act as a mobile tower in the skies, granting connectivity across expansive areas, covering up to 28km2 for 4G and even further for P25,” according to Simoco Wireless Solutions, which provided P25 radio equipment for the proof-of-concept. “Imagine ...

U-blox’ LARA-R6 LTE Cat 1 and LARA-L6 LTE Cat 4 cellular modules have been certified to Radio Equipment Directive (RED) cybersecurity, having passed RED article 3.3 d/e/f requirements using ETSI’s EN 303 645 standard. “As cyberattacks and privacy concerns grow, there’s an urgent need for wireless devices and products to feature enhanced security. With stricter regulations on the horizon, manufacturers ...

For coastal and mountainous terrain, Anritsu has added an up-link interference measurement to its some of its portable 5G and LTE TDD testers. At issue are stray signals carried long distances into cells where they interfere with the TDD up-link. The company explained: For 5G networks with a coastal or mountainous terrain, RF down-link transmissions readily become subject to atmospheric ...
