From slide number 1-37, how did we get value 0.0004? Show all your work. Describe the most popular wireless Internet access technologies today.
Compare and contrast them. What is the key distinguishing difference between a tier-1 ISP and a tier-2 ISP?
How long does it take a packet of length 1,000 bytes to propagate over a link of distance 2, 40 km, propagation speed 2.4*108s m/s, and transmission rate 2 Mbps?
More generally, how long does it take a packet of length L to propagate over a link of distance d, propagation speed s, and transmission rate R bps?
Does this delay depend on packet length? Does this delay depend on transmission rate?
