A system and method for avoiding collisions between packets transmitted in a wireless network ( 100 ). A first node ( 102, 106 or 107 ) in the wireless network ( 100 ) can transmit a packet to a second node ( 102, 106 or 107 ) in the wireless network ( 100 ), such that packet includes a header that is transmitted with a higher processing gain than the data, therefore, may be received and processed by a third node ( 102, 106 or 107. This allows the third node ( 102, 106 or 107 ) to detect the transmission of a packet by the first node ( 102, 106 or 107 ), which can cause the third node ( 102, 106 or 107 ) to avoid transmission of a packet during the transmission by the first node ( 102, 106 or 107 ) to avoid collision between the packets. The system and method further enables the nodes ( 102, 106 or 107 ) to determine whether they can transmit to another node ( 102, 106 or 107 ) based on estimates of interference conditions that can be experienced due to the presence of other nodes ( 102, 106 or 107 ).
