Latest Patents
One of Gehrke's latest patents is a communication system with a controlled talk around mode. This innovative method allows for talk around in an OFDMA communication system by sending a talk around request from a subscriber unit to a base unit. At the subscriber unit, a received signal strength indication (RSSI) of a signal received from the base unit is determined and sent back to the base unit. The base unit then compares the RSSI to a predetermined window. If the RSSI is above the window, the request from the subscriber unit is denied. If the RSSI is within the window, a sub-channel of the OFDMA communication system and a power level are assigned to the subscriber unit, allowing it to enter talk around mode. If the RSSI is below the window, the subscriber unit does not respond and instead goes into a direct communication mode independent of the OFDMA communication system.
