Abstract:
A method of determining RF coverage area in a point-to-multi-point RF transmission system and creating model maps showing serviceable business addresses within a given region. The method includes selecting a standard design signal strength level required to provide suitable service; obtaining field measurements of received signal strength from base stations at various points in the region under investigation; creating a model map of received signal strength having a signal strength level greater than the system standard signal strength level and excluding areas whose field strength measurements do not indicate suitable service; and creating a model map having a signal strength level smaller than the system standard signal strength level. The method is capable of providing more than 90% accuracy, and prevents needless dispatching of installation crews to a customer premise that is outside the effective RF coverage of the system.
