1. A 4-cell reuse cellular system is being rolled out into an operation area and you are the engineer taking charge of this project. The subscriber density for the operation area is 400 people per km2. The average traffic load generated per subscriber is 0.15 Er. You are required to deploy 7 clusters of cells in the operation area and provide a Grade of Service of 0.5% to the subscribers using the blocked calls delayed model. You found out that the total number of trunk channels available for the system is 100. Assuming that fixed channel assignment is used, compute: a) The traffic load that can be offered to the operation area. b) The cluster area that can be supported by the system. c) Based on the cluster area determined in part (b), what would be the proposed operation area?

Question

1. A 4-cell reuse cellular system is being rolled out into an operation area and you are the
engineer taking charge of this project. The subscriber density for the operation area is 400
people per km2. The average traffic load generated per subscriber is 0.15 Er. You are
required to deploy 7 clusters of cells in the operation area and provide a Grade of Service
of 0.5% to the subscribers using the blocked calls delayed model. You found out that the
total number of trunk channels available for the system is 100. Assuming that fixed channel
assignment is used, compute:

a) The traffic load that can be offered to the operation area.
b) The cluster area that can be supported by the system.
c) Based on the cluster area determined in part (b), what would be the proposed
operation area?
