With more switching point cleverlylocated, the T1 and T2 (and T3, T4) phases could be interlaced in time. That is, the hops would still bedivided by means of time division albeit interlaced, but the delay between the first time the RS receivesthe data, and the first time the MT receives that data would be smaller. The more switching points, thesmaller delay, although the overall time for receiving all data would remain the same.Page 35 (121)
