9. In the WPA Reauthentication Period box, enter the frequency (in days) at which the
authentication process will be re-activated with new keys, if a WPA2 authentication
method was selected.
10. In the WPA EAP Login box, enter the case-sensitive identifier (from 0 to
63 characters) used to recognize the device when a TTLS or PEAP authentication
method was selected.
11. In the WPA EAP Password box, enter the case-sensitive password (from 0 to
63 characters) used to secure the authentication process when a TTLS or PEAP method
was selected.
12. In the WEP Key box, enter the case-sensitive identifier used to secure the RF
connection when the authentication method is None. The WEP key must be the same in
the S4200 and in the access point.
13. In the RF Band list, select the radio frequency band used by the device. The available
values are:
802.11a (5 GHz OFDM)
802.11g (2.4 GHz OFDM)
Public Safety (4.9 GHz OFDM)
14. In the Channel list, select the frequency channel, within the selected band, that the
wireless system will use. It is the master device of the S4200 that selects the channel.
However, you can specify an initial value for the roaming process by which the S4200
will find its access point; be aware that this initial channel may not be the one used by
the access point.
In a 4.9 GHz band context, the list of channels varies depending on the chosen
bandwidth.
15. In the Channel Bandwidth list, select the width of the frequency channel when the
4.9 GHz public safety band is selected. This parameter only appears for the 4.9 GHz RF
band. The values can be 5 MHz, 10 MHz, and 20 MHz (default).
16. In the Tx Bit Rate list, select the data rate at which the device operates. A high bit rate
reduces the effective distance between two functional devices. You can set the bit rate
in slave devices only.
When a slave connects to its master for the first time, it automatically receives the best
possible value (the Auto value), with a default RF margin set to 15 dB (to change the
margin, see page 75).
Note: A change to the RF band is automatically applied because it has an immediate
impact on other parameters.
