Rockchip Launches Lowest Power WiFi Technology

Rockchip Launches Lowest Power WiFi Technology

Rockchip has announced at COMPUTEX Taipei that it has launched the world lowest power WiFi technology RKi6000 jointly developed with a third party. This technology makes WiFi power consumption equal to that of BT4.0 LE (Low Energy). The receiving power consumption is around 20mA during use, which is 85% lower than state-of-the-art WiFi devices for the Internet of Things (IoT), setting a benchmark power consumption level that should renew the standard for WiFi power consumption in IoT smart hardware globally.
