The electrical engineers at the University of California San Diego have developed a new ultra-low-power Wi-Fi radio integrated into a small chip for the IoT devices. It consumes only 28 microwatts of power, which is 5,000 times lower than standard Wi-Fi radios. The ultra-low chip can transmit data as far as 21 meters at a rate of 2 Mbps, which is enough for decent quality video. The chip will enable IoT devices to run for a longer time and work wirelessly in some cases.
The new transmitter will significantly increase the operating time on a single charge of various Wi-Fi battery sensors and IoT devices, including portable video cameras, smart voice speakers, and smoke detectors.
