ABSTRACT:
Apparatus for improving the signal to noise ratio in wireless communication systems through message pooling including hardware, software and protocol contained within a packet data communication system which enables a wireless communication system, for example an electronic display system, to adapt communication techniques to meet customer based accuracy requirements independent of changes in the signal to noise ratio of the communication channel and methods of using the same. Communication having low signal to noise ratios are improved using intelligent retransmissions of the communication signals and statistical detection or demodulation. Such techniques are particularly useful when used in wireless communication in unbalanced systems, such as electronic display systems.
