Determining which Wi-Fi channels are available:
Use a Smartphone (or PC) App such as
Wi-Fi Analyzer
to analyze the wireless
network environment, scan which WLAN frequency bands (e.g., Wi-Fi) are being
used for the Wi-Fi channels in the local vicinity. For example:
As illustrated in the screenshot from
Wi-Fi Analyzer
below, several Wi-Fi signals
are being used for specific Wi-Fi channels (i.e., channels 1, 6, and 11).
Determining which
ZigBee
channels do not overlap with the available Wi-Fi
channels:
By referring to the corresponding Wi-Fi and ZigBee channel table below, based on
the IEEE802.15.4 standard, the ZigBee transmission frequency can be adjusted in the
range from 2405 MHz to 2480 MHz, separated into 5 MHz sectors, providing 16
channels. In the table below, it can be determined that ZigBee channels 4, 9, E, and F
and Wi-Fi channels 1, 6, and 11 do not overlap. In this case, RF channels 4, 9, E, and
F can be selected.
