Problem 1: Suppose there is a 10Mbps microwave link between a geostationary satellite and its base station on Earth exactly below the satellite. Every minute the satellite takes a digital picture (of the earth) and sends it to the base station. Assume that propagation speed is 2.99x108m/s. a) What is the propagation delay? b) What is the bandwidth-delay product, R* dprop c) Let X be a the size of the photo. What is the minimum value for x that keeps the link continuously transmitting? d) If the pictures are half of such size, what is the maximum inter departure time between pictures that keeps the link busy? e) What is the average queueing time if l take a burst of 100 pictures of size S? What is the maximum S such that I finish transmitting them before the next scheduled picture is taken (60 sec) f) How wide is a bit over the channel? g) What is the size of a picture such that it starts to be received before the transmitter stops sending it? And what is the maximum amount of bits that can be on the channel at the same time? Problem 2: (cont from P1) Let's now suppose that the satellite takes pictures every Y seconds, with Y distributed as an exponential random variable, with mean one minute h) What is the probability a picture will be taken in the next K seconds? i) When, on average, the base station will start receiving the next picture
