Abstract

The invention provides a system for testing the aerial performance of a wireless USB modem and comprises a darkroom, a rotating floor that is arranged in the darkroom, a testing antenna and a computer, wherein, the wireless USB modem is connected with the started computer through a USB wire, and the computer is fixed in the top end of a rotating shaft that is vertical to a plane of the rotating floor; the USB modem is arranged in a proper position of the darkroom for implementing the great circle test of the USB modem. The invention further provides a method for testing the aerial performance of the wireless USB modem. Therefore, the invention can better utilize an OTA testing darkroom of existing cellphones, the hardware system of the rotating floor and the software system, and a three-dimensional directivity diagram and TRP and TIS data which are acquired from the testing can reflect the radiation and receiving characteristics of the antenna.

Description

technical field [0001] The invention relates to a wireless USB Modem over-the-air performance testing device and method, in particular to a USB Modem over-the-air (Over The Air, OTA) performance test in the wireless communication field. Background technique [0002] With the development of the second generation (2G) and third generation (3G) wireless communication systems, the capability of high-speed transmission of wireless data services is constantly improving. Wireless USB Modem is one of the wireless communication terminal products. It uses a USB cable to connect to a laptop or a desktop computer, and performs high-speed data transmission through a wireless communication network, such as a general-purpose modem under the Global System for Mobile communications (GSM). Packet Radio Service (General Packet Radio Service, GPRS for short), Enhanced GPRS (Enhanced GPRS, EGPRS for short) under GSM, Wideband Code Division Multiple Access (WCDMA for short) network under 3G commu...
