TI, Semtech Among Chip Companies Supporting Amazon Sidewalk Protocol

Amazon Sidewalk will bring connected devices together for a “seamless user experience,” blogged Texas Instruments Product Marketing Manager Casey O’Grady, after Amazon’s Sidewalk announcement (see 2009210032). The sub-1GHz long-range, low-power network will enable a sensor “that lets you know when it’s time to water" the backyard garden. TI devices for Sidewalk include wireless controllers supporting sub-1 GHz and Bluetooth Low Energy (BLE) and a wireless microcontroller with an integrated power amplifier for extended range. Developers can use the TI devices to build apps supporting the Sidewalk protocol; BLE allows “easy commissioning or over-the-air firmware updates,” she said. Semtech’s LoRa supports a long-range, low-power wide area network to connect a range of home devices or sensors, said CEO Mohan Maheswaran.
