Site Survey and Planning:
Performing a Site Survey
We cannot give precise recommendations for a site survey as every site will vary. However a site survey is a prerequisite
to installation in all cases. The correct and effective placement of base stations will prevent problems and maximize
coverage.
Site survey kits are available from Avaya. These contain a specially adapted base station that is able to operate
independently. The kit also includes handsets and necessary chargers.
· While performing a survey you will require the following information:
· Building Layout
Accurate building plans are an essential aid to both the site survey and also for later fault analysis. Ensure
that you have an accurate plan of the customer premises, including the locations of mains power outlets and
network connection points.
· The area of coverage required?
Which areas within the plans the customer expects to be covered. Do they expect coverage outside the
building and or in buildings separate from the main building.
· The number of simultaneous users within different areas?
Each base station can support up to 8 simultaneous calls.
· Perform the survey during normal business hours. The movement of large items of machinery such as lifts will
then be observable during the survey.
· Ensure that you have read this documentation and understand the importance of base station clusters and the
need for wireless synchronization between base stations within a cluster, including the need for redundancy.
· As the survey takes place, note whether additional network connection points will be required and or mains power
outlets. Consider the use of Power over Ethernet, if possible in order to simplify base station installation.
· As a general objective, the signal strength from one base station location to another should not drop below -70
dBm.
Using DECT Handsets for a Site Survey
This function puts the phone in the 'site survey mode'. While in this mode the phone can also receive a call to allow
audible checking of the call quality as you move around the survey area. .
1. Press Menu.
2. Enter R***76#.
3. Select Site Survey.
4. Press OK.
5. Press Esc.
6. The phone displays the IP Base Stations and the actual field strength of the receiving signal in dBM.
· RFPI
This line shows the PARK number of the IP DECT system to which the phone is connected.
· FE
This line shows the frame errors detected by the portable part (PP = the phone) and the fixed part (FP = the
base station to which it is connected). Occasional framing errors are acceptable.
· -dBM and RPN
These two lines show the signal strength (-dBm) and the Base Station ID (RPN) of the base station providing
each signal. The Base Station ID's match those shown on the IP DECT Base Station screen when accessing the
ADMM web configuration. Note that the signal strength is in negative numbers, for example 70 is a weaker
signal than 50.
7. To leave site survey mode, switch the phone off and on again.
