Use of location information in multi-radio devices for mmWave beamforming
A system and method are provided for using location services available from other radios in a multi-radio system to assist a beamforming mechanism, particularly in establishing and maintaining mmWave communication link. A majority of wireless client devices for use in a mmWave communication link are equipped with multiple radios. Many of the “other” radios include technologies that support location based services, including GPS, Wi-Fi and cellular communications. One or more non-mmWave in one device is used to provide relative location information regarding the other device with which the mmWave communication link is to be established. The relative location information is used to derive a direction for communication, and to compute beamforming parameters, in a limited set of transmit/receive sectors where the destination device is likely to be found, in order to streamline the beamforming process.
