3. (6 points) (a) In a CSMA/CD network with a data rate of 10 Mbps, the minimum frame size is found to be 512 bits for correct operation of the collision detection process. What should be the minimum frame size if we increase the data rate to 30 Mbps? Here we assume the maximal distance of two stations does not change (b) In a CSMA/CD network with a data rate of 10 Mbps, the maximum distance between any station pair is found to be 500 meters for correct operation of the collision detection process. What should be the maximum distance if we increase the data rate to 50 Mbps? Here we assume the frame size keeps the same
