Hot Spots - Samsung DECT 500 Installation And Programming Manual

Part 1: Site Survey and Overview of DECT Systems
The RSSI value can be measured with a Samsung D-5000 handset. Note that when
carrying out measurements, the handset must be off-hook.
During measurement it is necessary to take into account the effect a human body
has on the radio signal. This is done by either holding a hand over the antenna of the
handset or by turning the handset and body away from the Base Station in a way that
causes a "worst case" scenario, i.e. a position which results in the lowest RSSI value.
Approximately RSSI 65 / Q52>54 should be measured at the broken line. The Q
value should be stable.
Figure 1.2
The permanent Base Station should be placed in the position (position 3) in which
the RSSI value is 65 and has a stable Q value of 52 from the measured survey and
the demonstration Base Station in positions 1 and 2. Then the survey and demon-
stration Base Station can be moved to positions 4 and 5. The measuring process can
be repeated and the permanent Base Station is placed in position 6.

Hot Spots

It is possible to have four simultaneous calls on one DECT 1500 Base Station. If the
radio coverage in an area is OK, but users require more than the allowed number of
simultaneous calls, this is called a "Hot Spot". In a Hot Spot area, additional Base
Stations can be installed.
One or more additional Base Stations can be placed next to the existing Base Sta-
tion. In this way, small overlaps between the coverage areas of the Base Stations are
avoided.
