Radio signal travels from the BS to an MS along different paths-some direct, some reflected and some deflected. If the worst case difference in the path length traversed by a signal is 2 km, what is the minimum value of guard time that need to be used? Assume the signal propagation rate of 512 kbps.
a. 1.415 bits
b. 2.415 bits
c. 3.415 bits
d. 4.415 bits
Answer: c
