If multiple CSs cover the same area, the phone connection may become noisy or the number of possible
simultaneous calls with PSs may decrease due to interference between the CSs. For details, refer
to "3.11.5 Site Survey—Testing the Radio Signal Strength".
The required distance between CSs may vary depending on the environment of the installation site and
conditions in which the wireless system is used. Conduct a site survey to determine the appropriate distance.
