21	21	The single channel gateway has limitation to use with standard LoRaWAN sensor. In single channel gateway, the gateway can only set to work at one frequency and one data rate. A standard LoRaWAN Sensor can works in different frequency (3~~72 depends on the frequency bands) and different data rates. So Single channel gateway will lost most of packets because the frequency and data rate mismatch.

Some other LoRaWAN sensors, when work with Single Channel Gateway. we need to do some special configure like: Below set up instruction or [[Video Instruction to set End node to work in Single Frequency & Fix Data Rates>>url:https://www.youtube.com/watch?v=32eLnlYoLoI]] For a general LoRaWAN sensor, please see if similar setting (Set to work in single frequency and fix data rate) is possible. Otherwise, there will be problem for communication due to the limitation.
