Time division multiple access
Time division multiple access is a channel access method for shared medium networks. It allows several users to share the same frequency channel by dividing the signal into different time slots. The users transmit in rapid succession, one after the other, each using its own time slot. This...

TD-CDMA
TD-CDMA, an acronym for Time-division - CDMA, is a channel access method based on using spread spectrum across multiple time slots. It is shown that a mixture of TDMA and CDMA provides better quality of service for multimedia communications in terms of data throughput and voice/video...
