For a 3km wireless link, the data rate is 10Mbits/s and an idle AQR scheme is adopted. 1) If packets are sent in the size of N 4096 bits, calculate the link utlization efficiency where P 1x10 keep the same link utlization, how can you adjust the packet length 2) Assume channel becomes worse resulting in a Pb 1.5x 10-6. To N at this moment
