The “RF Channel”
parameter specifies the actual radio frequency channel to be
used by the RFU-2400 module, and must be set to the same channel if the
module is in the same communication group as other RFU-2400 modules.
-
Channel Selection:
As the 2.4 GHz ISM band is a globally available frequency range, a significant
number of devices operate within this band, which may, of course, generate a
high possibility of signal interference. Consequently, the selection of a suitable
channel is an extremely important consideration when implementing an
RFU-2400 network. The most ideal solution would be to select an RF channel
that is not occupied by other devices, as this will improve the efficiency of
wireless transmission.
-
Channel Selection Method:
The best approach when attempting to identify a suitable RF channel for use by
the RFU-2400 module is to employ a WiFi Analyzer application on a smartphone
or other WiFi enabled device to scan for WLAN channels that are currently
occupied by other devices within range of the RFU-2400 module, thereby
assisting in the detection of wireless signals in the vicinity and allowing an
analysis of the WLAN to be performed.
