GDK-20W DIGITAL WIRELESS KEY TELEPHONE SYSTEM
52
A list of possible configurations will help the customer to decide exactly what is required. A specification of where base
stations should be placed. This can be marked on the survey map, but additional information such as height and fixing
instructions should be included where appropriate.
A specification of the areas that will be covered by the base station and the areas that may cause problems. This can be
useful when testing the system.
The theoretical maximum number of overlapping cells is 10, if all time slots and frequencies are used. If not all time slots
and frequencies are used, this value is higher. However this is unlikely to be reached in practical situations.
For a large site where a thorough survey has been impossible, it may be prudent to add additional base stations to the
product offer to allow for unforeseen problem areas.
