Chosen Solution
Need to replace the third antenna on the i pad pro 9.7 who nobody knows what I am talking about,its on top left between speaker and camera,meas.4 1/2”,passes through the box underneath it and connects to the logic board below the top right speaker
Based on the teardown, wifi version has 3 antennas, which could be 3x3 MIMO wifi, integrated Bluetooth or 2x2 MIMO + 1 Bluetooth. Cellular model has even more complex layout. Don’t have the device so can’t test whether it is 3x3 or 2x2+1. Update, judging from the front end components, 2 at the bottom has the same capabilities and the top one seemed to be different. The wifi chip has 2 RF ports, one will split to the 3rd antenna at the top. So it is likely to be 2x2+1, not sure if it is based on features or bands though. Teardown: iPad Pro 9.7" Teardown
