Abstract

The invention discloses an OTA test system and method for NB-IoT equipment, wherein the system comprises: a darkroom; a rotating platform arranged in the darkroom and used for placing to-be-tested equipment which is narrowband IoT (Internet of Things) equipment based on a cellular network; an annular antenna support frame which is vertically arranged in the darkroom and on which a plurality of antennas are distributed; a control terminal; and a comprehensive test instrument which is connected with the to-be-tested equipment and the control terminal and is used for measuring transmitting performance and receiving performance of the to-be-tested equipment under control of the control terminal. The OTA test system and method provided by the invention solve a technical problem that the OTA test system for the NB-IoT equipment is absent in the prior art.

Description

technical field [0001] The present invention relates to the field of OTA testing, in particular to an OTA testing system and method for NB-IoT equipment. Background technique [0002] At present, more and more attention is paid to the test of the radiation performance of the whole device in the radio frequency performance test of the wireless terminal, and the radiation performance reflects the final transmission performance and reception performance of the wireless terminal. At present, there are mainly two methods for testing: one is to judge from the radiation performance of the antenna, which is a relatively traditional antenna test method, called passive test; the other is to test the radiation power and reception of wireless terminals in a specific microwave anechoic chamber. Sensitivity is called active test, and OTA (short for Over The Air) test belongs to active test. At present, the active performance of the whole machine is more and more valued by terminal manufa...
