The integration of the Radio and Antenna is making the OTA Lab a Mandatory part in the air interface test in 5G era. The OTA lab is responsible for two types of tests: 

- the pre-test for the algorithm

- Verifying the actual performance of Massive MIMO in live network. 

ZTE 5G OTA lab is consisted of three parts: two air interface chambers, one is Near-field chamber, another is Far-field chamber, and one console controls the test process and makes the analysis automatically.

Besides, ZTE also incubate some innovative solutions: 3D Broadcasting beam with: SSB 1+X, ATG (AIR TO GROUND) and promoting the commercial use of millimeter wave, greatly extends the deployment scenarios.
