Abstract
Abstract A method and system for enhanced data transmission within a cellular telephone system having multiple assigned voice channels separated by adjacent buffer voice channels. A data processing terminal is utilized to divide the data stream into multiple relatively short data packets which are then sequentially transmitted within alternate adjacent buffer voice channels. By switching from one adjacent buffer voice channel to a subsequent adjacent buffer voice channel, in a predetermined and repetitive order, as each data packet is transmitted, the amount of interference experienced in any one assigned voice channel is minimized. Synchronization between adjacent data packets may be achieved by either utilizing adjacent buffer voice channels in a predetermined and repetitive order or by concatenating an indication of the next buffer voice channel utilized with each data packet. A synchronization packet may also be included with each data packet to permit synchronization between adjacent data packets at the receiver.
