Problems solved by technology

[0005] 1) In order to meet the requirements of test accuracy and repeatability, there are certain requirements for the test environment. For example, indoor far-field testing requires a darkroom of a certain size; while outdoor far-field testing is easily affected by weather and external interference signals. This will bring problems in terms of test cost and test efficiency;
[0006] 2) Each test requires a large amount of data support, and it takes a long time to get the results;
[0007] 3) For some test items of AAS, such as the reliability test in the CE certification ex

Embodiment Construction

[0076] In order to facilitate the description of the present invention, the implementation of the technical solutions of the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined arbitrarily with each other.

[0077] The AAS wireless index test proposed by the present invention is mainly divided into two parts: AAS space characteristic test and AAS radio frequency index test. The specific test process is described as follows:

[0078] 1. AAS space characteristic test

[0079] The AAS spatial characteristic test can inherit the traditional base station antenna test environment and needs to be carried out in an antenna test field such as a darkroom. Mainly test the spatial characteristics of AAS, AAS spatial characteristics mainly include: AAS beam contro...

Abstract

The invention discloses a test method and a device for wireless indexes of an active antenna system. An over the air (OTA) test is used for testing spatial characters of the active antenna system and a near field coupling mode is used for testing radio frequency indexes of the active antenna system. The invention also provides a near field coupling test device which is a radio frequency testing cover. By the aid of the near field coupling test device, the radio frequency index test can be conducted to the active antenna system which is an integral device of an antenna and a multi-channel transceiver under the condition that any extra test interfaces are not required to be added. According to the comprehensive test method, the advantages of the OTA test and the near field coupling mode are combined fully, the defects and the problems of the OTA test and the near field coupling mode are overcome, and the test efficiency and the test cost are optimized.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a method and device for testing wireless indicators of an active antenna system. Background technique [0002] Active Antenna System (AAS) is a base station communication subsystem integrating multi-channel transceiver and base station antenna. It is an integrated device of antenna and multi-channel transceiver. The interface between them is an internal interface. Engineering It is difficult to directly test the RF port on the Internet, which brings challenges to its test. [0003] At present, the test of traditional base stations is generally divided into base station antenna test and base station equipment test. [0004] Most of the base station antenna tests currently use the OTA (Over The Air, spatial radio frequency) test method. This method can also be used for AAS testing. It is a method that can comprehensively test the wireless performance of AAS, includi...
