I am looking at creating a device within regulations for a medical environment with two Txing antennas, BLE (cypress FCC certified module) and 915MHz ST Spirit1 FCC certified module.
I have found multiple sources on the usage of the 915MHz band and other ISM bands. But I believe there is/are regulation(s) about the distance required between these two ‘co-located’ antennas, ie 915&2.4GHz in this case, but I cannot find the specific regulation. Has anyone had any experience with this or able to point me in the right direction?
Any help would be greatly appreciated!
Think what I may be after is ‘Section 15.212, Modules, Module Certification’
This is to do with modules, which will probably be used but a custom PCB config. maybe be used.
