5. A wireless Base Station (BS) is serving N users with a single channel having a capacity C bits/second. The BS has two options for serving the users a) Option1: BS divides the channel into multiple sub-channels using FDMA and assigns a dedicated sub-channel to each user and process his traffic in a separate buffer. b) Option2: BS put the traffic from all users in one buffer and transmits all traffic packet- by-packet on the same channel in a first-come-first serve order Compute the transmission time of each packet (on the air) for Option1 and Option2 if the packet size is L bits.

A wireless Base Station (BS) is serving N users with a single channel having a
capacity C bits/second. The BS has two options for serving the users
a) Option1: BS divides the channel into multiple sub-channels using FDMA and assigns a
dedicated sub-channel to each user and process his traffic in a separate buffer.
b) Option2: BS put the traffic from all users in one buffer and transmits all traffic packet-
by-packet on the same channel in a first-come-first serve order
