Learn how to set up private LoRaWAN channels on RAK gateways for custom frequencies, TTN, ChirpStack, and region-specific IoT deployments.
Overview
This feature allows RAK gateways in Packet Forwarder (PF) mode to support user-defined LoRaWAN private channels, offering flexible frequency and parameter configuration. It enables integration with custom regional frequencies or proprietary server-defined bands outside standard LoRaWAN regional specs.
In real-world deployments, LoRaWAN networks often require custom channel plans due to:
Region-specific frequency regulations not fully covered by standard LoRaWAN regional profiles
Custom frequency plans used by servers like ChirpStack or The Things Stack that fall outside LoRaWAN regional defaults, requiring the gateway to match those exact frequencies
Private or closed networks isolating devices on non-standard frequencies to reduce interference
Alignment with existing spectrum allocations in mixed-network environments (e.g., utilities, mining, agriculture)
How It Works
Private channels can be configured directly through the WisGateOS2 Web UI, allowing you to define a custom set of channels that the gateway will use for LoRa® communication.
Once configured, these private channels replace the default regional channel plan. The gateway will then operate only on the selected frequencies for both uplink and downlink.
This approach ensures:
Full compatibility with LoRaWAN servers that use custom frequency plans, such as ChirpStack or The Things Stack.
Flexible deployment in non-standard or region-specific frequency environments.
Private Channel Setup
This section explains how to configure private channels on a RAK gateway.
Preparations
Before you begin, complete the following steps:
Obtain the exact frequency plan from your LoRaWAN network server.
Verify configuration alignment. The gateway's private channel settings must exactly match the server-defined frequency plan to ensure proper uplink and downlink communication.
This guide uses The Things Network (TTN) Israel 917~920 MHz plan, covering channels 1-4 and 11-14, as an example.
Check official references. Detailed frequency information can be found in the LoRaWAN Frequency Plans for The Things Stack.
Confirm gateway registration. Make sure the RAK gateway is already registered in TTN with the correct frequency plan selected.
RAK Gateway Configuration
Private LoRaWAN channels can be enabled only when the gateway is running in Packet Forwarder mode. Make sure the gateway is in this mode before configuring the channels.
Access the RAK gateway's web UI.
Navigate to LoRa > Configuration.
- Under Frequency Plan, click to expand the View detailed regional parameters of the frequency plan dropdown.
- Set Conform to LoRaWAN to OFF and confirm the action.
- Click Edit under LoRa Concentrator.
- Manually configure the frequencies based on your server's plan.
Click Confirm to apply channel configuration.
Click Save changes to store the configuration.
Verify Gateway Status in TTN
- Open the TTN Console.
- Navigate to your registered gateway.
- Verify that the gateway status shows recent activity (e.g., Last activity 5 seconds ago).
RAK gateways automatically connect to the TTN EU1 cluster when operating in Packet Forwarder mode. To connect to other TTN clusters (e.g., US1, AS1) or to different network servers such as ChirpStack or a private LNS, you must update the gateway’s packet forwarder settings with the correct server address and port.
Troubleshooting
| Issue | Possible Cause | Suggested Solution |
|---|---|---|
|
No uplink packets visible |
Incorrect server address or protocol |
Make sure that the gateway is set to Packet Forwarder mode and verify that the server communication settings are correctly configured for your LNS |
Frequency plan mismatch |
Check the frequency plan used by your server and ensure that all channels are correctly entered in the gateway UI. |
FAQs
1. Can I use private channels with any network server?
Yes. RAK gateways in Packet Forwarder mode can work with any LoRaWAN network server that supports manually defined channel plans, such as The Things Stack (TTS), ChirpStack, and private LNS deployments
2. Will the network server automatically sync channels to the gateway?
No. Private channel configuration is entirely manual. The server will not push frequency plans to the gateway.
You must ensure full alignment between your gateway's private channels and the server's expected frequencies.
3. Do I need to configure anything on the node (end device)?
Yes. Your LoRaWAN end device must use the same uplink channel set as the gateway. If using a fixed Rx2 frequency, it must also match the gateway's configured downlink frequency.
4. Can I use both LoRa Concentrator 0 and 1?
Yes. Each concentrator (and its sub-radios) can monitor different frequency blocks. Use both if your channel plan spans a wide frequency range.
