EST P/N AA107-Horizon
HORIZON FREQUENCIES OF OPERATION
In a wireless Ethernet network all of the ESTeem Horizon must be set to the same radio frequency of operation (channel) and
bandwidth. The following table shows the channels and corresponding frequencies of operation for each model of ESTeem. The
frequency of operation is selectable when configuring the mode of operation of the Horizon (reference Chapter 3).
Figure 1: Radio Frequency Channel Selection
RF COMMUNICATIONS DATA RATE
The RF data rate of the Horizon can be programmed for operation at multiple data rates. The RF data rate can be set for a fixed
rate or a specific range that is dynamically scaled by the Horizon from monitoring the received signal quality. Dynamic scaling
means that the Horizon will operate at the highest RF data rate that is programmed into unit. If the received data quality drops
below the required minimums for reliable communications, the Horizon will reduce the data rate to the next lowest step to increase
signal quality. Conversely if the signal quality increases above the minimums the Horizon will increase the RF data rate the next
highest level.
The ESTeem Horizon is set at the
factory to operate at maximized
scaling speed data rates and should
not need adjustment. The RF Data
Rate is programmed in the Horizon
through the
Advanced
Menu>Wireless LAN
Settings>Wlan0 Device
and the
value for
wlan0_OPRATES:
. In the
example shown in Figure 3 the RF
Date Rate is programmed to dynamic
scale all data rates to 54 Mbps
(recommend factory default setting).
To set the values for the data rate,
check the box next to the listed data
rate to enable this rate for operation.
