Description
LoRa frequency bands are divided into multiple channels at a certain interval according to LoRaWAN Regional Parameters. On configuration pages about LoRa end-devices of many famous platform, you can often see the settings about using certain channels of a regional genre, like US915, EU868, etc. When working as network server, Milesight LoRaWAN gateways support not only settings for all end-devices, but also special frequencies for individual ones, and this article is about how to set them.
Requirement
Milesight UG6x LoRaWAN gateway with firmware version 60.0.0.37 and above.
Globel Setting
Navigate to Network Server -> General -> Global Channel Plan Setting, you can find a drop-down box indicating current channel plan of this NS, and its global channels. Since LoRaWAN regional plans vary on their numbers of frequencies, this chapter below will elaborate on each regional plan that UG6x supports. For UG8x gateways or UG6x gateways with firmware version 60.0.0.36-r13 and below, channel mask is represented by hexadecimal. For more info please refer to How to Configure Channel Mask in Milesight Gateway. For UG6x gateway with firmware version 60.0.0.37 and later, channel is represented by decimal index. Every index indicates a frequency point.

Individual Profile Setting
Only UG6x using CN470, AU915, US915 supports to set individual channel frequency for specific Profile.
Navigate to Network Server -> Profile -> [certain profile] -> Advanced, simply add the frequency you prefer, or shown as idle on Noise Analyzer. If left blank, it means this profile uses global channel plan setting.
Note:
- When using this feature, ensure your LoRaWAN device ADR is enabled;
- For US915/AU915 frequency, please add at least 2 channels, only one channel can not work.
