Problems solved by technology

[0007] 1. In order to set up the antenna, it is necessary to move the ground absorber to provide space for the floor antenna stand, which will destroy the uniformity of the full anechoic chamber
[0008] 2. Every time the throughput test is performed, the antenna frame needs to be moved into the anechoic chamber for antenna erection. After the test is completed, the antenna frame is moved out of the anechoic chamber so that the anechoic chamber can be tested for other projects, which will cost a lot of mo

Abstract

The invention provides a full anechoic darkroom comprising a test room, a test rotary table and an antenna frame device. The test room comprises an outer wall provided with a hole; the test rotary table is arranged in the test room; the antenna frame device comprises an antenna frame, a pipe and a driving device; the interior of the pipe is used for arranging the antenna frame, and one end of the pipe is communicated with the test room; and the driving device is connected to the antenna frame and used for controlling the antenna frame to enter into and exit from the pipe and controlling the test rotary table. The invention has the advantages that the antennal frame is not required to be manually moved, the height of the antennal frame can be fixed, the driving device can control the antenna frame to enter into and exit from the pipe, and errors caused by manual operation is avoided.

Description

technical field [0001] The present invention relates to an anechoic chamber, in particular to a fully anechoic chamber. Background technique [0002] In order to detect the throughput capability of the wireless network card, it is necessary to test the throughput of the wireless network card. The transmission of wireless network card data is divided into two parts: sending (Tx) and receiving (Rx). Sending and receiving are related to data transmission rate and bandwidth. The most common 802.11 transmission protocol is 802.11a / b / g, and 802.11n provides a higher transmission rate. 802.11a high-speed wireless local area network (WLAN) protocol uses the 5GHz frequency band (Frequency Band), the maximum transmission rate is 54Mbps, 802.11b / g uses the 2.4GHz frequency band, the highest transmission rate of 802.11b is 11Mbps, and the maximum transmission rate of 802.11g can reach 54Mbps transmission rate. When performing a throughput test with a higher transmission rate, a highe...
