In a CDMA/CD network with a data rate of 10 Mbps, the minimum frame size is found to be 512 bits for the correct operation of the collision detection process. What should be the minimum frame size if we increase the data rate to 100 Mbps? To 1 Gbps? To 10 Gbps? Compare and contrast a controlled access protocol with a channelizing protocol. A network with one primary and three secondary stations uses polling. The size of a data frame is 150 bytes. The size of the poll, ACK, and NAK frames are 8 bytes each. Each station has 2 frames to send. How many total bytes are exchanged if there is no limitation on the number of frames a station can send in response to a poll?
