Radio Bandwidth
This is the Bandwidth of the radio and it is factory set. It will be either 12.5KHz
(narrow band) or 25Khz (wide band)
(narrow band) or 25Khz (wide band)
Transmit Power Level
This allows adjustment of the radio power. Do not set the radio power above the
allowed setting for your country or radio license. You can reduce the power for
short range applications, or to allow the use of high gain transmitter antennas
while still complying with the emission requirements of your license.

Transmit Data Rate
The 450U-E can be configured for different radio transmission rates. Note:
reducing in the configured data rate may increases the reliable range of the
module (transmission distance).

Frequency Step Size
The Frequency Step size is the spacing between frequencies that you can select
when configuring the TX and RX frequencies. The steps sizes available are 5Khz or
6.25KHz.

Beacon Interval (AP only)
This interval is the period between beacon transmissions sent by an Access
Point. The default value is 15 seconds, and it may be adjusted from 1 to 60
seconds. Reducing the Beacon Interval will increase the amount of radio
messages in the system which could compromise normal communications.
Do not change unless advised by an Elpro Systems Engineer.

Fragmentation Threshold (Client Stations only). The maximum transmission unit (MTU) of data over the
radio. If more than this number of bytes is input into the module, it will be
transmitted in more than one message (or fragmented).
