A wireless communication system with one or more remote transceivers for transmitting a wireless data signal at an actual frequency that is different than the expected frequency and a base transceiver that can automatically adjust to receive the actual frequency. Each remote transceiver is adapted to initiate a wireless data signal at a selected time that is unique to that remote transceiver. The expected frequency is sequentially pre-determined in a pseudo-random sequence with each remote transceiver having a unique sequence. The base transceiver can respond to the remote transceiver at the actual frequency. Both the remote transceiver and the base transceiver can convert the wireless signals in a single step to baseband.

Wireless communication system for adapting to frequency drift

A price display system for a store includes spread spectrum radio broadcasting of UPC and price data from a transmitter in the store to a large number of receivers. Each receiver is connected to one or more LCD displays attached to the store shelves, and each receiver provides the relevant information to each of the connected displays. The displays and receivers are battery powered.
