Abstract
A system, apparatus and method are disclosed for communicating between a short range wireless (WLAN) user device, such as a wearable, phone, or tablet, with a base station. Traditional low power communication (e.g., WLAN, WiFi, Bluetooth, cellular links, etc.) involve an inefficient amplification process of a signal from the WLAN user to the base station, whereby significant power must be expended in the WLAN user device making it unsuitable in many applications. A reflector link paradigm is disclosed in which the user device communicates by modulating the extent of signal reflected back to the base station. An enhanced reflector is also disclosed which overcomes adverse effects of ambient reflections.
