Abstract
The quality of a communications channel carrying data packets is determined by establishing if a packet is received correctly or incorrectly. Check means provides a signal to a microprocessor for each correct reception event and each incorrect reception event. A value, held in a two byte counter is indicative of the quality of the communications channel. For each correct reception event the value of the counter is decreased by an extent dependent on the value already held in the counter. For each incorrect reception the value of the counter is increased by an extent dependent on the value already held in the counter. When the stored counter value exceeds a preset threshold value indicating poor channel quality, a comparator produces an output signal to initiate a handover operation to another communications channel.
