In order to ensure that the wireless communication devices manufactured by various manufacturers have a certain level of compatibility and stability, wireless communication devices must pass the tests established in accordance with the wireless communication protocol standards, and each of the Rosers before shipment. Quality testing, etc., so how to simplify the test and reduce the cost associated with the test 'is the problem that each manufacturer wants to solve. For example, a wireless communication module used in a conventional wireless communication device generally needs to test the electrical characteristics and functional characteristics of the wireless communication module. In terms of electrical characteristics, the spectrum analyzer is used to detect the antenna center frequency or RF power value used by the inductive wireless communication module, or the ammeter is used to detect the maximum current consumption value of the inductive wireless communication module, in order to wirelessly communicate. The electrical characteristics of the module are in compliance with electrical compatibility safety regulations. In addition, in terms of functional characteristics, the wireless communication module to be tested is usually placed in an outdoor open space, and the antenna test equipment is used to actually verify the long-distance transmission condition and the magnitude and range of the received signal sensitivity. However, due to the increasing complexity of the existing space and the surrounding environment due to the development of wireless communication, there are various sources of radiation interference sources or barriers during signal transmission. It is necessary to find a place where there is no interference. #difficult. In addition, 'outdoor testing must be limited by weather conditions' due to unstable weather conditions, resulting in wireless communication module detection 201108643 results will cause errors due to environmental changes. Therefore, existing wireless communication devices usually use the Anechoic Chamber used by the external testing laboratory to perform simulation tests in open space. The electric darkroom can mainly shield external electromagnetic interference, and on the other hand, it can shield the emission source without causing electromagnetic interference to the outside world. In terms of the structure of the anechoic chamber, in order to achieve the above objectives, that is, to achieve high absorbing and high barrier properties, conventionally, absorbing materials are added to the six walls of the anechoic chamber to prevent internal signal reflection and increase the degree of isolation from the outside. . In order to simulate the anechoic chamber into an outdoor open test site. In the actual use of the anechoic chamber test of the wireless communication module, the first anechoic chamber is first used to detect the electrical characteristics of the wireless communication module, that is, the static electrical characteristics such as the antenna center frequency, the RF power value, or the current consumption, and then the first The second anechoic chamber performs dynamic functional characteristic detection such as reception sensitivity. However, the above-mentioned conventional test procedure must be performed in stages and sub-items to make the overall test time longer. The space required for the anechoic chamber is large and the installation cost is high. In summary, the prior art has the following disadvantages: (1) The test anechoic chamber is expensive, the test time must be reserved in advance, the test equipment takes up a large space, and the test takes a long time. (2) The noise floor measurement system (Noise floor) is limited to verifying the extent to which the antenna layout is disturbed by the system noise. It is impossible to fully verify the impact of the wireless communication device on the communication quality after the overall assembly. 201108643 (3) The test equipment is too large to be used in the production line products (OQC, Out-going Quality Control), that is, it cannot correctly and effectively screen the problems caused by the assembly of the production line.
