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, ...

ST is aiming at secured Bluetooth, Zigbee and other 2.4GHz comms with a wireless MCU family. Called STM32WBA6x, the controllers have a 100MHz Arm Cortex-M33 core with floating-point and DSP extensions, backed by up to 2Mbyte of flash and 512kbyte of ram. The flash memory is dual-bank. “Thread, Zigbee, Matter and Bluetooth are naturally low-bandwidth protocols, [which] means that downloading the ...

Nordic Semiconductor will be demonstrating the forthcoming space comms capabilities of its nRF9151 low power System-in-Package (SiP) at GSMA’s Mobile World Congress (MWC) in March. Specifically, the 3GPP compliant, low earth orbit (LEO), Non-Terrestrial Network (NTN) connectivity capabilities of the system. These will be made available by a future firmware release. The company will be highlighting its role for IoT, ...

For Mobile World Congress, MediaTek has announced a high-end AI phone modem for 3GPP Release 17 and forthcoming Release 18 – after announcing three mid-range phone processors this morning. The 5G modem, called M90, supports 12Gbit/s downlink and Release 17 2T-2T uplink Tx switching. “This new modem supports sub-6GHz FR1 with up to 6CC carrier aggregation and mmWave FR2 with ...

To be announced at Mobile World Congress in Barcelona, MediaTek has filled out its latest generation of phone processors. Positioned under its flagship Dimensity 9400 and premium 8400, the new 7400 and 7400X are optimised for gaming and AI camera processing. Built on TSMC’s 4nm process, both 7400 chips have an octa-core CPU: 4x 2.6GHz Arm Cortex-A78 cores and 4x ...

Increasing dependence on wireless devices highlights the need for comprehensive RF radiation emission level testing, says Jon Kenny. As dependence on wireless devices that emit RF radiation continues to grow, so do the complexities of those devices and their international regulatory requirements. Specific absorption rate (SAR) testing plays a crucial role in assessing and ensuring the safety of such electronic ...

Panasonic has picked Nordic’s nRF54L15 around which to build its latest Bluetooth and Matter module: the 10.35 x 9.8 x 1.9mm PAN B511-1C. Equipped for Bluetooth 6 and 802.15.4, its embedded microcontroller is a 128MHz Arm Cortex-M33, backed by 1.5Mbyte of non-volatile Rram and 256kbyte of ram, and the module has a built-in antenna. Scheduled for production in Jun, output ...

The Z-Wave Alliance – the standards body for smart home and IoT wireless comms – has published its Z-Wave 2024B Specification Package for improved device interoperability and security. The organisation has also introduced a new level of Z-Wave Alliance membership. The Z-Wave 2024B Specification covers changes to the Z-Wave Certification program, updated Z-Wave Command Classes, and new tools to support ...

U-blox has introduced Bluetooth LE modules with PSA Certified Level 3 security, based on Nordic Semiconductor’s nRF54L family of wireless mocrocontrollers. The modules “are qualified against Bluetooth Core 6.0 that includes Channel Sounding, enabling tracking and locating use cases”, according to  U-blox. The multi-protocol 2.4GHz radio can also handle Thread, Zigbee, Matter, Nordic’s proprietary 2.4 GHz protocol and Amazon Sidewalk. ...

Silicon Labs has announced a pair of Bluetooth-enabled microcontroller families, to be available in Q2 this year: BG22L (diagram right) devices are aimed at asset tracking tags and personal healthcare devices, and support Bluetooth 5.4 and Bluetooth Direction Finding. Processing power comes from a 38.4MHz Arm Cortex-M33 processor with up to 352kbyte of flash and up to 24kbyte of ram ...
