In the problems below, the rate expressed in bits per second is written as bps and the rate bytes per second as Bps.
Data transmission between your smartphone and antenna tower. A powerful antenna tower transmits data down to your smartphone at a rate equal to 300 Mbps, while your less-powerful smartphone transmits data back up to the tower at 75 Mbps. Assume the band-widths and noise levels are the same in each transmission direction. How are the signal energies at the tower and cellphone related? (Hint: Use the channel capacity equation and ignore the +1 in the log2 term.)
