- Radio Spectrum Bandwidth: Two choices are available - Normal
(default setting) and Wideband. In the Normal mode, each channel
occupies 20 MHz of radio spectrum. In the wideband mode, each channel
occupies 40 MHz of spectrum.
If a radio is likely to be installed in an area with other 5.8 GHz radios
nearby, it is best to use the Normal bandwidth setting as this allows for
more non-overlapping channels. This is also the case if multiple radios are
to be co-located on a single tower or rooftop.
If maximizing throughput and distance is of primary importance, then it
may be best to use a Wideband bandwidth. At any given datarate (e.g. –
36 Mbps), the Wideband setting will attain a longer link distance as
compared to the Normal setting. The Wideband setting also allows for
higher data rate settings not available on the Normal setting.
After changing the Radio Spectrum bandwidth value, be sure to click the
Select button below.
The following is the table for available radio frequencies and data rates for
each option. (Note that the allowable frequencies may differ from the table
below depending on the country of operation)
QUARTER (5MHz)
Frequency (MHz) 4945, 4950, 4955, 4960, 4965,
4970, 4975, 4980, 4985
Data Rate (Mbps) 9, 6, 4.5, 3, 1.5
HALF (10MHz)
Frequency (MHz) 4945, 4950, 4955, 4960, 4965,
4970, 4975, 4980, 4985
Data Rate (Mbps) 18, 12, 9, 6, 3
NORMAL (20MHz)
Frequency (MHz) 4950, 4955, 4960, 4965, 4970,
4975, 4980
Data Rate (Mbps) 36, 24, 18, 12, 6
NORMAL (20MHz)
Frequency (MHz) 4960, 4965, 4970,
Data Rate (Mbps) 36, 24, 18, 12, 6
- Radio Frequency (MHz): the center frequency of the selected
frequency channel. In the Quarter mode, each channel is 5 MHz
wide. In the Half mode, it is 10 MHz. In the Normal mode, it is 20
MHz. In Tubo mode, it is 40 MHz.
- Data Rate: air transmission/receive data rates. Note that different
data rates are available for normal and wideband modes, as
detailed in the table above.
All radios on a given wireless network must use the same Bandwidth,
Frequency and Data Rate setting.
After changes are complete, click on the Update button. If a mistake
is made, you can restore the previous setting by clicking the Reset
button. To make changes effective, reboot the unit by clicking on
Advanced -> Reboot from the Navigation Toolbar.
Static Routing
There are two possible choices in configuring the unit as a router: Static routing
or RIP. The choice depends on your overall network consideration and your
preference. For details, consult any textbook on IP routing.
In order to activate Static Routing, go to the Configuration – Static Routes
menu option in the navigation toolbar to see the screen below
For each static route, you need to add the following information
• Network Address – Enter the network address of the static route.
• Network Mask – Enter the network mask of the static route.
• Gateway – Enter the gateway of the static route.
Once you have typed in the above, click the Add button to include the newly
typed static route to your static route list. Then, your static route screen will
look like the following:
