Abstract

A repeater device may be utilized to enable forwarding extreme high frequency (EHF) communication between EHF-enabled wireless devices. The repeater device may utilize polarization isolation to prevent and/or reduce interference between received and transmitted EHF RF signals in the repeater device. The repeater device may utilize signal gain control to maximize the transmit signal strength while forwarding EHF RF signals to enhance and/or enable polarization isolation between received and transmitted EHF RF signals. Received Signal Strength Indicators (RSSI) may be utilize to measure signal strength of transmit and/or received EHF RF signals to enable performing signal gain control. The repeater device may utilize control connections to enable communicating with the EHF-enabled wireless devices to facilitate performing signal gain control at the repeater device. Non-EHF interfaces, for example Bluetooth, may be utilized to establish the control connections.
