b) Assuming two 1 Mbps Ethernet LANS (LAN Y and LAN Z) are connected by a bridge. An application in LAN Y sends 32 packets per second to LAN Z. Each IP packet has total size of 1480 bytes (excluding the preamble and cyclic redundancy check (CRC)). Assuming the inter-frame gap (IFG) is 9.6us, determine: i) The total size of the frame. ii) The time taken for the frame to send through LAN Z.

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 1 Compute the transmission time of each packet (on the air) for Option1 and Option2 if the packet size is L bits.
