The present invention provides a kind of test environment of household radio product anti-interference ability, examines the anti-dry of household radio product
Immunity energy.The present invention manufactures various intensity, Ge Gexin according to the air interference data collection and analysis of numerous typical home environment
The static state in road, dynamic disturbance source simulate the practical domestic environment of wireless product, set up a stable interference source and test environment,
The tests such as performance and interference game experiencing are tested the speed by interference through-wall performance, interference to examine the anti-interference ability of wireless product.
It can be widely applied to the test of the anti-interference abilities of products such as wireless router, wireless terminal, wireless aps (wireless access point), examine
Survey the performance and stability under wireless product interference environment.
As shown in Fig. 2, in step sl, room number is 4 in the shielding house, room 3, the room being respectively arranged successively
Between 2, room 1 and room to be measured.Wherein, household radio product to be measured is placed on room to be measured, that is, the DUT (quilt of this example
Measurement equipment) room position D.A, B, C point are respectively the wireless client that the tested household radio product of distance wears 3,2,1 wall
Position.
In step s3, this example the first dynamic disturbance source and static interference source are placed on E point in room to be measured position, and described
F point position is arranged in room 2 in two dynamic disturbance sources.
All rooms and extraneous shielding are avoided extraneous wireless signal from increasing the interference of this test environment, caused by the present invention
Environmental fluctuating is tested, test data is unstable.The layout in room, the distribution of interference source, the putting of position, the design of test point are all
It can be adjusted or rebuild according to user's application scenarios.
The present invention is suitable for building for all wireless networks, such as current 2.4G wireless network and 5G wireless network.With
Under be described in detail by taking the 2.4G wireless network of current main-stream as an example.

It realizes: being analyzed according to the signal number of acquisition, signal intensity profile, design the dry of multiple interference sources and different interference intensity
Disturb source environment.
In step s 2, it is analyzed according to the annoyance level of the distribution situation of interference source channel and different channels, selection is dry
It disturbs most some channels and multiple interference sources is respectively set, and distribute different interference intensity grade, it is quiet by different proportion distribution dynamic
State interference source and different channel width is configured to each interference source.
This example according to interference source channel distribution analyze, the 1st, 6, the amount of interference of 11 channels it is most, so in the 1st, 6,11
Channel respectively designs 2 interference sources and is distributed in three interference strength class, and according to the pro rate dynamic interference source of 1:1.6
With 40/20MHz bandwidth.
In order to test the balance that environment interferes different channels, by for the 1st, 6, in some channel reselections of 11 channels
The heart or adjacent frequency channel are the second dynamic disturbance source, and this example selects the adjacent frequency dynamic disturbance source of second gear interference strength dynamic as second
State interference source, to guarantee that these adjacent frequency interference sources cause different degrees of overlapping to interfere the bandwidth of each tested channel.This example
Respectively it is arranged 1 pair in the 2nd, 7,12 channels, as the adjacent frequency dynamic disturbance source of second gear interference strength (- 60~-80dBm), to protect
It demonstrate,proves these adjacent frequency interference sources and respectively causes the overlapping of 17MHz/19MHz/19MHz bandwidth to interfere the 1st, 6,11 channels.
This example is dry at the static state that interference strength is -80dBm weak signal below in the smallest channel design of channel utilization rate
Disturb source, make each channel respectively by the interference of different multiples, such as distribution 1,1,2,3,4,5+1,6+2,6+8,7,8,9,10,11,
11,12,13, make the 1st, 6,11 tested channels by 5.3-5.5 times of interference, this example makes the 1st, 6,11 channels are respectively by about
5.41 times/5.45 times/5.36 times of interference.
This example can voluntarily adjust interference strength class and strength levels according to environmental requirement.This example is in step s 4, described
Interference strength is divided into third gear, respectively first grade of interference strength, second gear interference strength, third gear interference strength, wherein first
Decaying is not added in shelves interference strength, interference source；Second gear interference strength, interference source add 40dB to decay；Third gear interference strength, interference
Source adds 60dB to decay.The interference strength of this example can be arranged according to the wireless power of self-control attenuating plate adjustment interference source.
The first dynamic disturbance source of this example and the quantity in the second dynamic disturbance source are respectively 3 pairs, each pair of dynamic disturbance source it
Between mutually with different rates transmit data, simulation interference source occupy wireless channel, the working channel of equipment under test is interfered.
This example be set as each pair of between mutually with 1Mbps speed rates flow.
Static state is zero load, and the static interference source of this example is only reported with the management message such as beacon frame and probe response frames and control
Text causes static interference to equipment under test.The quantity in this example static interference source is set as 19.
The present invention uses stable interference source, and test data is more stable, more acurrate, and easy to maintain；Occur in product different
In normal situation, the problem that is more advantageous to quickly is checked and positioning.Test environment and method of the invention closer to user's application scenarios,
Keep product performance under user environment more preferable, more stable.
In the case where the present invention tests environment, the interference through-wall performance of wireless product can be tested, interferes test the speed performance and interference ring
Border webpage, video, game experiencing.
1, through-wall performance is interfered
Wireless performance under the interference environment of each channel of wireless product and different bandwidths can be tested under environment of the present invention,
Interference environment wireless product through-wall performance can be tested simultaneously；It can verify that wireless product wirelessly arrives wired transmission, reception, two-way handles up
Amount, the delay of PING packet loss, radio connecting rate and signal strength.
2, the performance that tests the speed is interfered
For wireless product by intelligent acess internet, it is each that wireless client using the online tool of testing the speed can test wireless product
Bandwidth availability ratio through walls under a channel, each bandwidth and interference environment.
3, user experience is interfered
Game on line, Online Video and net under each channel of wireless product, each bandwidth and interference environment through walls can be tested
The experience of page opening speed tests it and wears stifled, two stifled, three walls a game on line experience under interference environment, and record is wireless
Situations such as client plays the delays of various games on line, Caton, goes offline.
It is as follows that the present invention tests the performance data comparison of testing the speed of environment and existing interference environment bandwidth:
Show that disturbed test environmental testing data of the present invention are more steady than existing environmental testing data according to the above test result
It is fixed, it is easier to judge radio stability under wireless product anti-interference ability and interference environment, while stable interference environment is easy to
Problem under product abnormal conditions is quickly checked and positioning.
