Abstract

The invention relates to a test method of the mobile terminal near filed radiation and the device thereof; wherein, the device includes a spectroanalyzer (51), a RF cable (32) and an electromagnetic wave receiving detector (52). The method includes the steps of: connecting the spectroanalyzer and the detector (52) via RF cable (32); configuring the spectroanalyzer (51), collecting the near field radiation continuous interference high frequency energy received by the detector (52); 1.4) adhering to and scanning the surface of the mobile terminal (14) by the electromagnetic wave receiving detector (52) till all the region is scanned over. In the method and the system thereof, the screening chamber replaces the microwave non-reflection dark chamber, and the trial test is carried out for product before the formal radiation continuous interference test so as to provide a favorable condition according to the conversion relationship of the near/distant field of the radiation electromagnetic field. The cost is saved, and the development period is shortened.

Description

technical field [0001] The invention relates to mobile terminal testing technology, in particular to a mobile terminal near-field radiation testing method and device thereof. Background technique [0002] At present, the number of digital mobile subscribers in the world has reached 1.3 billion, and with the issuance of 3G licenses in China, this number is expected to double in the next few years. It is predicted that in 2008, the global communication industry will present a huge market of up to 2 billion mobile users. [0003] Global mobile services and applications are growing in three main directions: voice, multimedia and enterprise applications. Mobile data services will have an increasing share in the mobile market. As of September 2003, the number of global mobile data service users reached 100 million, accounting for 7.7% of the world's 1.29 billion mobile users, an increase of 14% compared with the statistics in June 2003. By 2007, the proportion of mobile data se...
