that uses two 30 kHz simplex channels to provide full duplex voice and control channels.
Assume each cell phone user generates 0.1 Erlangs of traffic. Assume Erlang B is used.
(a) Find the number of channels in each cell for a four-cell reuse system.
(b) If each cell is to offer capacity that is 90% of perfect scheduling, find the maximum
number of users that can be supported per cell where omnidirectional antennas are used
at each base station.
(c) What is the blocking probability of the system in (b) when the maximum number of
users are available in the user pool?
(d) If each new cell now uses 120° sectoring instead of omnidirectional for each base station,
what is the new total number of users that can be supported per cell for the same blocking
probability as in (c)?
(e) If each cell covers five square kilometers, then how many subscribers could be supported
in an urban market that is 50 km × 50 km for the case of omnidirectional base station
(f) If each cell covers five square kilometers, then how many subscribers could be supported in
an urban market that is 50 km × 50 km for the case of 120° sectored antennas?
