Description varix 200/varix 14 (DECT)
2 Planning a cordless communications network
Hand-over is initiated when the sensed value drops to -76 dBm.
In the display, the field strength is indicated by a bar, the height of which varies with the field
strength.
Please observe: a signal field strength of 5 in the overall wireless loop is not always suffi-
cient! Field strength 7 supports a better and more reliable connection.
The maximum length of the bar display is 10 characters. While the bar is being displayed,
the reference base station transmits a continuous tone which permits you to assess the con-
nection subjectively (speech transmission quality). To conclude monitor mode, switch off the
portable part. When you switch this on again, it is switched back to normal operating mode.
Please observe:
in order to verify the footprint you should carry out the tone test mentioned
above; a positive result for the test together with a field strength of at least 7 (bar display)
signifies a good field strength.
- symbol
indicates that the portable part is within reach of a base station
- symbol
indicates the status of the wireless link:
- blinks
= connection is being established
- on
= connected
- off
= no connection
After you have determined the range of the base station at the first location, plot the results on
the building plan and select the location for the second base station. At this location, repeat
the whole procedure, and so on.
