2. You have a wireless channel occupying frequency spectrum from
72GHz to 95GHz. The SNR of this channel is 60dB. What is the
channel capacity in Gbps, according to Shannon Theory? (5
points)
3. Calculate the total time required to transfer a 384 KByte
file in the following cases, assuming an RTT of 16ms, and an
initial 2*RTT of handshaking before data is sent (7.5 points):
a) the bandwidth is 2.7 Mbps, and data packets can be sent
continuously. (2.5 points)
b) the packet size is 768 Bytes, the bandwidth is now changed to
1.8 Mbps, and after we finish sending each data packet we must wait
one RTT before sending the next. (2.5 points)
c) the packet size is now 2048 Bytes, the bandwidth is now
1Mbps, and after we finish sending each data packet we must wait
one RTT before sending the next. (2.5 points)
