Hardware preparation and installation
Performing a DECT site survey
You can use the following procedure to confirm that the DECT RF spectrum is not fully used
by other DECT equipment in the area. Perform the site survey if there is likely to be a number
of other DECT systems in the area. Also, it is recommended that you perform the survey during
normal site operation.
The handset can measure the RSSI of all channels within one slot. If the RSSI value calculated
is under –60dBm for at least one channel, that slot is determined to be a clear slot. This process
is repeated for all slots, after which the handset displays the number of clear slots.

Note:
The base station and its repeaters must be no closer than 17 feet (5 meters) from
other DECT base stations and repeaters, including other D100s on the same IP
Office.
The repeaters registered to a particular D100 base station must be at least 35
feet (10 meters) from the base station, and 35 feet (10 meters) from other
repeaters. This range limitation is particularly important in multi-floor
deployments.
