COLLISION DETECTION METHOD

Abstract: a wireless device may receive packets according to a protocol, such as bluetooth, and may rapidly react to receive an interfering rf packet instead of dropping the first rf packet and the interfering rf packet, to decrease message delay due to collisions in high device density environments. when a received signal strength indicator (rssi) difference between the interfering rf packet and the first rf packet exceeds a threshold, the device may detect the interfering packet and resync a portion of its circuitry to lock on to and receive the interfering packet. the wireless receiver may detect the interfering rf packet by detecting one or more of: a specific resync byte sequence, an increase in rssi, or a phase shift. additionally, a wireless device may add the specific resync byte sequence to an rf packet of a standard protocol.
