  1. TDM is better than FDM • FDM: each connection gets a channel. But the channel is broken into time slots (one slot for each packet for THE connection assigned to the channel) • TDM: each connection gets a time slot. And there are many other connections with other slots • In both cases, when a packet arrives, it has to wait until “its” time slot arrives • The slots are evenly spaced in both cases, so the waiting time is the same • But the transmission time is lower for FDM, and so TDM gives an overall lower delivery time (wait + transmission). Hence, TDM is better • Both approaches start the transmission at the same time, but TDM finished sooner
