Problems solved by technology

However, this method does not work for wireless LAN equipment. Since the wireless LAN equipment is a time-division device with the same frequency, its uplink and downlink share the same frequency, so the uplink and downlink cannot be completely separated. For the radiation power test, if the frequency is tested by the receiver The sum of the power under the test cannot reflect the actual power of the EUT (device under test), and the same rea

Description

technical field [0001] The invention belongs to the technical field of radio frequency testing of wireless communication products, in particular to the design of a testing system for wireless local area network equipment. Background technique [0002] With the development of modern industry, the electromagnetic environment is deteriorating day by day. All kinds of wireless communication equipment can only guarantee the quality of communication service if they have good radiation radio frequency characteristics and receiving characteristics, that is, the total radiation power (TRP) must be large, and the total receiving sensitivity ( TIS) should be high, that is, the air interface OTA (over-the-air radio frequency test) performance of the product should be better. Especially in the 2.4 / 5GHz license-free frequency band, the wide application of various wireless products makes the electromagnetic environment of this frequency band extremely harsh. The wireless communication equi...
