4.5.4 Radio Test Environment
The antenna efficiency, antenna gain, radiation pattern, total radiated power (TRP),
and total isotropic sensitivity (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:
Passive Tests

Antenna efficiency

Gain

Pattern shape

Envelope correlation coefficient
Active Tests

TRP: GSM, WCDMA, CDMA, TD-SCDMA, and LTE systems

TIS: GSM, WCDMA, CDMA, TD-SCDMA, and LTE systems
Figure 4-1 shows the SATIMO microwave testing chamber.
