Finalizing the plan
-

When all Base Station positions on the map are verified and the plan is in place, discuss

with the parties concerned whether, due to local traffic requirements, (see Chapter 5,

Section 5.2), extra Base Stations are needed in particular areas. Integrate these Base

Stations with the plan.

Thus a final Base Station plan is made and tested simultaneously.

Base Station Count Estimating

Base station counts may be estimated by using the approximation formula seen below. Enter the
total coverage area of interest as well as the anticipated radius of coverage.

N = number of base stations
Atotal = total coverage area
R = anticipated coverage radius
