CTPhone 1900 System Planning
Pre-installation Tasks
Several factors affect the quality of service for a CTPhone 1900 system:
• location of base stations
• number of CTPhone handset users within base station range
• obstructions between base stations and CTPhone handsets
• coverage area
• the desired grade of service and quality of coverage
The purpose of this section is to provide you with information and explain
tasks that you should complete to ensure the best operation of your sys-
tem.
Site Survey
1 Obtain building blueprints.
2 Note the construction materials used in walls (including insulation) and
floors between multi-story buildings, and note window coatings and
coverings. Also note any large metal objects, such as equipment,
doors, and fluorescent lamp shades.
In general, signals are attenuated to some degree when they have to
pass through any barrier, however, some materials such as metal,
attenuate to a much greater degree.
3 Note high traffic areas, such as conference rooms, cafeterias, and
manufacturing floors.
4 Note office locations and numbers of CTPhone handset users within
the site.
Determining Base Station Requirements
To determine the number of base stations you need in a system, you must
consider base station broadcast range and your traffic requirements.
