Strange channel plan for china deployment

Hi there,

In a work project, it is planned to deploy Lora devices using a non-standard frequency plan.
Here it is :

The weird stuff is :

  • The “Lora” channel is not on a standardized frequency and is between 2 standard channels
  • The RX2 channel is not the recommanded one by the Lora regional parameters
  • The “Lora” channel use a SF7 250 khz bandwith which is not in the Lora standard

We were told this frequency plan is not standardized but commonly used. The big problem for us is it is not compliant with standard.

Is anybody has already seen such a weird channel plan ? And if it is the case, how it was dealed with ?

Many thanks.
