ABSTRACT:
A collision detection mechanism includes a transmission protocol which locates a gap in a station's transmission, of fixed duration and position, relative to start of transmission. Collision detection is enhanced since random timing of collisions normally results in filling in the gap. This condition is more readily detectable than detecting the simultaneous presence of energy from two transmitters. The transmission protocol is followed unless the transmitting station detects a collision, in which event gap creation is inhibited. The gap detecting equipment may be located at a network head end.
