===== How Can I activate the Class-B on my Wirnet iBTS gateway? =====

\\
//Class-B is disabled by default on firmware 4.0.x// \\

<note important>**Your end-devices must be class-B compliant to make this feature functional. \\
Note that the class-B configuration does not apply to such gateways (Wirnet iFemtocell and Wirnet Station) since they have no GPS.**
</note>

You can activate the feature by clicking the  ''Support class B Enable'' checkbox in the Radio Configuration menu of your gateway:

  - From the dashboard, select Management > Gateways
  - select your gateway EUI
  - select Configurations > Radio

In the bottom of the page (scroll the page down), you should see: \\

If this feature is not visible, you must check your radio configuration:

  - select "USE RAW EDITOR" button in the right side of the page below the graph
  - insert the following piece of code at the end of the configuration file (don't forget the first coma!):

<code>
    ,
    "gateway_conf": {
        "beacon_enable": false,
        "beacon_period": 128,
        "beacon_freq_hz": 869525000,
        "beacon_freq_nb": 1,
        "beacon_freq_step": 0,
        "beacon_datarate": 9,
        "beacon_bw_hz": 125000,
        "beacon_power": 14,
        "beacon_infodesc": 0,
        "ref_latitude": 0,
        "ref_longitude": 0
    }
</code>
    
This piece of code must be customized according to your country. Refer to the LoRaWan Regional Parameters specifications that you can find here: [[https://lora-alliance.org/resource-hub/lorawanr-regional-parameters-v102rb]]
    
Your page should look like as following:

Then, perform the following steps:

  -  Submit the changes to your gateway by selecting the ''SEND'' button. The gateway will reboot and apply the new radio configuration. \\
  -  Select the "USE VISUAL EDITOR" button (just below the graph in the right side of the page) \\
  -  Check that the feature "Support class B" is visible \\
  - Check the box to enable class B feature \\
  - Click the ''SEND'' button once again. The packet forwarder will restart applying the B-class configuration.
