The third screen of the wizard is devoted to the radio and modem configuration. You can enable
or disable the RSSI LED on FODU housing and specify the antenna size you are using for the link. This
step also allows specifying the main radio parameters – Tx power (depends on frequency band and
the capacity chosen) and Tx channel. Available channels can be checked using “Spectrum analysis”
page.
Modem configuration allows choosing appropriate mode comprising channel bandwidth (10 or
30 MHz), capacity at maximum modulation and E1 or T1 channels.

Note that Tx power should not exceed equivalent isotropically radiated power (EIRP) limitation.
The final screen allows checking the selected settings and applying them. The optional settings
are as follows:
–
Clear cfg file before the new settings will take place – resetting all the other parameters,
not mentioned here, after configuration execution
–
Set local machine time – uses the time of your laptop
–
Save this configuration into cfg file – configuration is automatically written in
configuration file
(!) In the table below please see interdependence between antenna used and allowed SAF
FreeMile Tx output power range.
