onsider a broadband bus with a number of equally spaced stations with a data rate of 10Mbps and a bus lenght of 1km.
1) What is the average time to send a frame of 1000 bits to another station, measured from the beginning of transmission to the end of reception? Assume a propagation speed of 200 m/us
2) If the two stations begin to transmit at exactly the same time, their packets will interfere with each other. If each transmitting station monitors the bus during transmission, how long before it notices an interference, in seconds? In bit times?
