Gsm/Wcdma Antenna Requirements; Radio Test Environment - Huawei MU509 Series Hardware Manual

HUAWEI MU509 Series HSDPA LGA Module
Hardware Guide
On the user board, there are various interference sources, such as the LCD, CPU,
audio circuits, and power supply. All the interference sources emit interference signals
that affect the normal operation of the module. For example, the module sensitivity
can be decreased due to interference signals. Therefore, during the design, you need
to consider how to reduce the effects of interference sources on the module. You can
take the following measures: Use an LCD with optimized performance; shield the LCD
interference signals; shield the signal cable of the board; or design filter circuits.
Huawei is able to make technical suggestions on radio performance improvement of
the module.

4.6.4 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 6GHz. The test items are described as follows:
