Statistical TDM makes efficient use of the bandwidth only if the arrival pattern of the data stream is probabilistic. TDM requires the transmitter and receiver to be synchronized periodically. TDM performs efficiently if the arrival pattern of the data stream is probabilistic. Statistical TDM is efficient if the data stream is deterministic.
