Abstract: OTA test(test for antenna performance) is one of the vital test items in wireless device authentication test. Concepts of OTA and requirements made by relevant standards is introduced in this paper, in addition, three solutions of OTA test are analyzed in detail. The original field electromagnetic anechoic chamber, one of the schemes, is one of the popular solutions currently. However, some problems arise in this system, including huge investment, high difficulty in construction and unabling to test MIMO terminal without upgrading. While the reverberation chamber enjoys a high reputation with its high test speed, small size and the ability to test MIMO terminal. What’s more, this solution is authorized by 3GPP in 2011 December. Finally, constructive opinions are suggested in this paper, and shows that it is necessary to perform OTA testing for operators.
