Channel Selection
WI-MOD-E-G modem (2.4 GHz 802.11b/g)
Selection is done by picking one of the channels from the drop down "Channel" list. If Auto is selected the modem will
select the best channel based on signal level and channel density. Channel can also be manually selected by picking the
channel number from the list. Available channels 1-11 are 20MHz, channels 41-51 are 10 MHz and channels 21-31 are
5MHz. Turbo channels can are also be selected depending on country.
WI-MOD-E-A modem (5GHz 802.11a)
You can select an individual channel from the list keeping in mind that the channel will have some transmit and/or DFS
constraints as indicated in Section 3.1 - "Selecting a Channel" and "APPENDIX C - ".
If using the Auto mode you will need to select the appropriate groups that you wish to use and the modem will
automatically select an available channel from within the selected groups.

level. E.g. selecting 54 Mbps fixed data rate will reduce the transmit power
from 400mW down to 125mW. This is to comply with 802.11 regulations.
This interval is the period between beacon transmissions sent by an Access
Point. The default value is 100 milliseconds, and it may be adjusted from 50 to
4095 milliseconds.
Configure the maximum distance the radio signal is expected to travel. This
allows the modem to compensate for the flight time of messages as they pass
from the transmitter to the receiver, and as the acknowledgement messages
are returned. Setting this value larger will cause a small reduction in
throughput. Setting this value too small will cause communications problems
over longer distances. Default distance is 5km
This should be used to prevent unwanted eavesdroppers from detecting the
radio network System Address (SSID) by passively listening to beacon
transmissions from the Access Point. When disabled, Access Points will not
transmit the System Address openly in Beacon messages. This is particularly
useful in unencrypted radio networks.
Allows compatibility with Layer 3 Bridge devices. See section 3.6 - "
Compatibility"
