Problems solved by technology

Although this test scheme can comprehensively test the overall spatial RF radiation characteristics and receiving sensitivity of WLAN equipment, this method cannot simulate the characteristics of WLAN equipment in actual use. For example, the network performance we are very concerned about includes: connectivity, throughput, bandwidth and latency

Embodiment 1

[0059] This method is invented to use a good darkroom environment to formulate a test that can comprehensively reflect the overall wireless coverage performance of home wireless LAN access points.

[0060] see figure 1 , the present invention discloses a wireless local area network access point performance testing system, said system comprising: a throughput testing server 21, two gold machines 22, two adjustable attenuators 23, two measuring antennas 24, a throughput testing client11. Among them, the choice of gold machine is to choose a wireless LAN card with 802.11abgn and 2X2 MIMO characteristics that is widely used in the market and has passed the Wi-Fi Alliance certification as the gold machine for testing.

[0061] The throughput test server 21 is connected to two gold machines 22, and the two gold machines 22 are set to work in different frequency bands (such as one gold machine works in the 2.4GHz frequency band, and one gold machine works in the 5GHz frequency band)...

Embodiment 2

[0104] The difference between this embodiment and Embodiment 1 is that this embodiment also includes a RF conduction performance test process, an antenna radiation performance (passive and active) test process, and the like. The specific test method is as follows:

[0105] 【RF conduction performance test】

[0106] 1. Conducted emission power test

[0107] Purpose of the test: mainly to provide a basis for judging the results of other subsequent tests by testing the conducted emission power value as a basis.

[0108] testing process (such as figure 2 shown):

[0109] 1) Set the tested AP to work in 802.11b mode, the rate is 11Mbps, the channel is 1, 6, 11 in turn, transmit continuously and output the maximum power, and measure the output power of the tested AP with a vector signal analyzer.

[0110] 2) Set the tested AP to work in 802.11g mode, the rate is 6, 12, 24, 36, 54Mbps, the channel is 1, 6, 11 in turn, transmit continuously and output the maximum power, and use th...

Abstract

The invention discloses a system and a method for testing the performance of an AP (Access Point) in a WLAN (Wireless Local Area Network). The system comprises a throughput testing server, two gold machines, two adjustable attenuators, two measuring antennas and a throughput testing client, wherein the throughput testing server is connected to the two gold machines; the two gold machines are respectively connected to the two antennas through the two adjustable attenuators; and the throughput testing client is connected to a to-be-measured AP. The system and the method for testing the performance of the AP in the WLAN can test the wireless coverage performance on the whole, and comprehensively test the wireless coverage performance and direction performance of a product from point to surface.

Description

technical field [0001] The invention belongs to the technical field of wireless communication, and relates to an access point test system, in particular to a wireless local area network access point performance test system; meanwhile, the invention also relates to a method for testing the performance of the wireless local area network access point. Background technique [0002] With the rapid development of global Internet technology, wireless network technology is also developing rapidly. Among them, the 802.11 standard and wireless local area network technology (WLAN) are one of the main forces. At present, wireless local area network products have spread in every corner of people's lives, especially for ordinary households to access the Internet through wireless local area network access points, such as telecommunications and other operators' ADLS networks for Internet surfing. Although the wireless local area network makes thousands of households free from the trouble o...
