====== 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):
