4.5.4 Radio Test Environment

The antenna efficiency, antenna gain, radiation pattern, total radiated power (TRP),
and TIS can be tested in a microwave testing chamber.
Huawei has a complete set of OTA test environments (SATIMO microwave testing
chambers and ETS microwave testing chambers). The testing chambers are certified
by professional organizations and are applicable to testing at frequencies ranging
from 380 MHz to 6 GHz. The test items are described as follows:
