Planning For Multiple Systems - Nortel Meridian Companion Reference Manual

• Learn where the users need service. If all of the users do not need to go
everywhere, the audio quality of the service can be maximized.
• Avoid overlapping systems. If you must overlap systems, minimize the
number of overlapping cells.
• Keep all users in the same area on the same system. If users in the same
area must be on different systems, keep most of them on one system.
This strategy minimizes the required number of Base Stations and
maximizes audio quality.
• Where possible, group the cells of each system together on the floor
plan. For example, system A serves the east side of a site and system B
serves the west side.
• To determine the anticipated number of portables per cell, use the total
number of cells of the systems to which a user is registered.

Planning for multiple systems

1. Gather site information. Include the system recommended by the sales
group.
2. Survey the site as if it is a single system. See either "Covering a single
floor indoor area" on page 29 or "Planning a multi-floor coverage area"
on page 57, as required for your site.
3. Do traffic calculations for the entire site as if it is a single system to
determine the number of Base Stations for each cell (this is an estimate),
then add the number of Base Stations for the entire site (see
"Determining the number of Base Stations per cell" on page 37).
4. Use the appropriate Companion installation documentation to determine
the number of systems required to serve the site based on the users'
movements.
5. Divide the site into the number of required systems based on the users'
movements.
6. Recalculate the number of Base Stations required for each cell for each
system (see "Determining the number of Base Stations per cell" on
page 37). If required, include the number of additional users and Base
Stations a system can support.
