2.3.5. Co-Existing with 802.11b Networks
In some cases, if a WIT2492-based network is located in close proximity to an 802.11b
network, the WIT2492-based network can interfere with the 802.11b network. To avoid
causing this interference, the WIT2492 radio supports a selection of hopping patterns that
avoid the various 802.11b direct sequence channels. These limited band hopping patterns
allow WIT2492-based networks to be used with 802.11b networks without impacting the
performance of the 802.11b networks. The hopping pattern is selected using the pe
command. Please refer to the section 5.3 Protocol Commands for details.

Use of the WIT2492 within the European Union is limited to a maximum transmit power
including antenna gain of 20dBm. If gain antennas are to be used, the low power setting
of the WIT2492 must be selected. This setting sets the transmit power at the antenna
connector to 10dBm. In this setting a maximum of 10dB of antenna gain may be used. To
select low power mode, at the > configuration mode prompt enter:
