Abstract

The present invention is a system and method to provide a scientific and quantitative measurement in finding optimal locations for placing new micro or pico cells. Signal strength information of a test transmitter measured by mobile stations is reported to a base station serving a macro cell via call quality messages that the mobile stations are located. A post-processing tool 330 counts the number of call quality messages having a signal strength level measured from the test transmitter above a threshold during a measuring period indicating that a call can be offloaded to the new micro or pico cell. The estimated offloaded traffic volume is then calculated, preferably in Erlangs.
