Site Planning - Avaya D100 Installing And Administering

Site planning

Prior to deploying a base station and installing repeaters at a site, you must ensure that the site is
prepared to support the D100 and its DECT equipment. You must choose a location for the base
station that is central to the users and the coverage area. The best method to determine the
location of the DECT equipment is to use a floor plan. See
You can perform a DECT site survey using the handset to confirm that the DECT RF spectrum is
not already fully in use by other equipment in the area. See
page 29 and Performing a base station survey
Empty site survey results differ from those of the same site once occupied. Perform the survey
during normal business hours in order to assess the areas of usage and the effect of operating
and moving equipment.
Repeater installation
If you want to extend the range of the base station by using repeaters, you require repeaters for
each base station in use. You should register repeaters prior to deployment to avoid unnecessary
travel between the base station and the repeater after the repeater is mounted.
The system supports handset roaming and hand-off between a base station and its repeaters. A
repeater must be within the cell radius of the base station to which the repeater registers, and
subsequent linked repeaters must be within the cell radius of the previous repeater.
A repeater can handle up to four channels, and you can register up to six repeaters to each base
station. Note that a chain of linked repeaters is also limited to four channels, since all channels are
carried by the first repeater in the chain.
You must place the repeaters in a location that maximizes the number of available channels, while
placing the initial repeater within the cell radius of its base station. Note that you can only link up to
three repeaters in a row and that each repeater must be within the cell radius of the other
repeater.
Repeater installation scenarios:
• Long and narrow coverage
In a situation where you are attempting to cover a long and narrow area with equal coverage,
you must place the base station in the middle of the coverage area and extend repeaters in
both directions outward. This reduces the amount of linking. If you find that you require too
many repeaters, or you have more than eight active channels, you might install an additional
base station.
For example,
- Scenario 1: RP3 — RP1 — BS — RP2 — RP4
is far preferable to
- Scenario 2: BS — RP1 — RP2 — RP3
because in the second scenario you can place, on average, only one channel per repeater,
whereas in the first scenario, you can place, on average, two channels per repeater.
• Broad coverage
