• Max Transmit Power (Remote Only)—Sets/displays maximum RF
power output level in dBm of the Remote. Power level is still
controlled by the AP, but it is limited to the maximum level set
here. This setting should reflect local regulatory limitations and
losses in antenna transmission line. (
See “How Much Output
Power Can be Used?” on Page 167 for information on how to
calculate this value.) [
0—30; 30 (900 model) 0—23; 23 (3650 model)
• Receive Power (AP Only)—View/set the receiver gain setpoint
for the expected strength of incoming signals from Remotes.
This setting indicates at what level (in dBm) the AP expects to
hear the Remote stations. A setting of -70 would set the AP
receiver’s gain to a relatively low level, while a setting of -85
would be a comparatively high gain setting. [
-100 to -20; -75]
• Frequency Control—Opens a submenu where you can view or set
frequency mode bandwidth, channel and other parameters as
described in
Frequency Control Menu below.
•
Advanced Configuration—Opens a submenu where you can view
or set modulation, protection/hysteresis margins, data compres-
sion, ARQ settings, and other parameters as described in
Advanced Configuration Menu on Page 72.
•
Receive Diversity (900 MHz Remote Only)—Allows enabling or
disabling the RX2 antenna port for receive operation. The use of
two antennas allows “diversity” reception which helps mini-
mize the effects of fading due to multipath reception of signals.
Frequency Control Menu
The items shown on this menu vary depending on the Frequency Mode
Selection (
Single Channel, Static Hopping, Hopping w/Hand-offs). Examples
of all three screens are provided below, followed by a description of the
menu items.
