For countries in which DFS is not enabled, the
Frequency Channel
list displays only the channels and
frequencies allowed for the selected country. See “Dynamic Frequency Selection” on page 82 for more
information.
Multicast Rate
The rate at which data is to be transferred. This drop down box is unavailable when DDRS is enabled.
The default data rate for the MP.11 is 11 Mbps; the default data rate for the MP.11a is 36 Mbps. The SU
must never be set to a lower data rate than the Base Station because timeouts will occur at the Base Station
and communication will fail.
Selections for Data Rate are as shown in the following table.

Antenna (Subscriber Units only)
Antenna displays the proper antenna port,
Internal
or
External
, for the wireless interface.
Antenna Gain (Base Station units only)
You can modify the sensitivity of the radio card when detecting radar signals in accordance with ETSI and
FCC Dynamic Frequency Selection (DFS) requirements. Given the radar detection threshold is fixed by ETSI
and the FCC and that a variety of antennas with different gains may be attached to the MP.11/a, you must
adjust this threshold to account for higher than expected antenna gains and avoid false radar detection
events. This can result in the units constantly changing frequency channels.
You can configure the threshold for radar detection at the radio card to compensate for increased external
antenna gains.
The Antenna Gain value ranges from 0 to 35. The default value is 0.
Satellite Density
The Satellite Density setting is a valuable feature for achieving maximum bandwidth in a wireless network. It
influences the receive sensitivity of the radio interface. Selections are
Large
,
Medium
,
Small
,
Mini
, and
Micro
. See “Satellite Density” on page 83 for more information.
Registration Timeout
This is the registration process time-out of an SU on a Base Station. Default is 5 seconds.
Network Secret
A network secret is a secret password given to all nodes of a network. An SU can only register to a Base
Station if it has the same Network Secret. The Network Secret is sent encrypted and can be used as a
security option.
