phone 7 connections located on iphone?

[iMore Question]

hello can you help me tell me if you know where the connections for wifi,Bluetooth,gps are located on the phone 7 as I have just got an aluminium case & it interferes with connections & hopefully I'll be able to mod cut a hole in the case where condition points are to allow better connections.

Thanks

Hi, welcome to iMore.
Here is a tear down of the iPhone 7. You can see where all the antennas are.

But in my opinion, you would be better off with a case from any other material, really.
