Confidea Wireless System Installation and User Manual

5.3.2. Use of multiple Confidea
wireless systems
When the Confidea wireless system is set to
automatically select the carrier frequency, the
Confidea carrier frequency will be dynamically set to
another channel if another Confidea wireless system
occupies the same channel. This dynamic frequency
allocation ensures that each Confidea wireless
system will be set automatically to different
frequencies.
When the Confidea wireless system is set to
manually select the wireless carrier frequency, you
must make sure the Confidea wireless carriers of the
different rooms do not overlap each other.
5.4. Max range of WCAP
A single WCAP has a range of 30m in “open field” .
However the max range can be significantly less
depending on the positioning of the WCAP itself and
direction of the antennas in relation to the position
of the delegate units.
See chapter 5.5 for detailed info
Note :
Wifi access points and use of 5gHz
band
Some wifi accesspoints which support
IEEE 802.11n may also use 5gHz band
when they are configured in DualBand or
Backhaul mode!
Note :
Manual or automatic frequency
selection?
If more than one WCAP or Wifi
accesspoints are in the same room or
within 30m. range , it is strongly advised
that not more than one of them uses
automatic frequency selection , to avoid
that the frequencyscanning is disturbed
by the other accesspoint(s) . If multiple
accesspoints are used within each other’s
reach, manual frequency selection based
on frequency planning is strongly
recommended .
Note :
Selecting frequency
When using manual frequency selection
in 5gHz band , ideally the frequency
selection is done in such way that
between 2 used frequencies , there is a
40Mhz “distance” to avoid interference
by RF sidebands.
Attention:
Certain buildingmaterials like concrete ,
or metal may absorb part of the RF
signalradiation, resulting in a reduction
of the max distance between the access
point and units.
