RF Channel
1. RF Channel：
Code
Frequency (MHz)
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.
