Rx configuration

The gateway cannot listen to all frequencies simultaneously. Up to 8 frequencies can be configured in Configuration ⇒ Rx configuration ⇒ Rx configuration.

To understand how the frequency configuration works, it is necessary to know that the Wirnet gateway hardware contains two RF front-ends. Each of these front-ends has a 0.8 MHz Bandwidth. Thus, all 8 channels must be contained within these two 0.8 MHz intervals.

To properly configure the Rx channels, the center frequencies of the front-ends must be defined.

Once the center frequencies are defined, each channel can be configured.

Here are a few rules/information to configure the frequencies:

• Both front-ends are not necessarily used.
• Both front-end's bandwidth can overlap.
• Channels can overlap.
• All 8 frequencies can be contained within one single front-end's bandwidth.
• Not all 8 frequencies are necessarily used.
• Avoid the use of the front-end center frequency as a channel.

Example of a typical configuration for 868MHz band (868.1MHz, 868.3MHz and 868.5MHz are mandatory in most countries using 868MHz end-devices):

Example of all 8 frequencies contained within one 0.8MHz interval:
