3.5 CONFIGURING RADIO
PARAMETERS
There are two primary data layers in the MDS entraNET
network—radio (RF) and data. The data layer is dependent on the radio
layer to work properly. The
Radio Configuration Menu is the primary
menu used to set radio parameters. This screen includes the Skip Zone
Options Submenu .

•
RF Output Power
—( We recommend that you review this setting. )
Use this selection to set the RF output level of the transceiver.
Settings are displayed in dBm, and must comply with regulatory
limitations for your area. See
Table 2-1 for default settings and
range. [
20-30; 30
]
•
Dwell Time
—Duration of one hop on a particular frequency in the
hopping pattern. This field is only changeable on an AP;
Remotes get their value from the AP upon association. Dwell
time is the same as hop time. [
7, 14, 28 msec; 14 msec
]
•
Contention Window Min
—Sets the number of random contention
slots to use on first attempt. [
0-15; 2
]
•
Contention Window Max
—Sets the maximum number of random
contention slots to use. [
0-15; 10
]
•
Broadcast Repeat Count
—Because broadcast messages are not
acknowledged, noisy environments can prevent some Remotes
from receiving a broadcast. This parameter sets the number of
times that point-to-multipoint messages are transmitted by the
AP. Higher values increase the reliability of communications,
but also increase over-the-air congestion. [
