Basic requirements of WLAN shielding box

Author:admin   AddTime:2021-03-14

RF input configuration, RF isolation, test interface, calibration, test limits, and packaging effects are all important issues to be considered during the test process to ensure effective and accurate measurements. It is the basic requirement of WLAN shielding box to be able to effectively and accurately test the various capabilities of WLAN equipment. WLAN equipment uses a pair of antennas for diversity reception and sometimes also for transmission. In order to perform this test, the controller must have a method to select an effective antenna on the DUT, which can be achieved by the internal switch of the DUT. Therefore, the controller should be able to configure the DUT to select one of the antennas and use it for relative power measurement.



In the WiFi test environment, the first step is to select the measurement method. There are two main options: a test system based on the so-called "reference device (golden radio)" and a test system based on standard test equipment. Both systems have their own advantages and disadvantages in terms of complexity, performance, and equipment price. In addition, the selected test system architecture will also affect the throughput, test limit tolerance, test range, and flexibility of the test system to adapt to the new design.
