I have a question about the RAK2287 product

I have a question about the RAK2287 product.

It is a RAK2287 product and will be used as a gateway device by connecting it to a Raspberry Pi.

Looking at this product, it says that it supports 8ch.

Does the story that this product supports 8ch as a specification mean that it can receive multiple LORA messages of different frequencies at the same time?

Or does it mean that I can receive multiple LORA messages on the same frequency?
