The present invention provides wireless aps method for testing performance and detecting system in a kind of WIFI of the test based on RSSI.The wireless signal of the consistent standard of intensity is formed in this method around wireless aps antenna to be measured, RSSI value during by showing that wireless aps receive the wireless signal of this standard, and the RSSI value intensity is compared, wireless aps to be measured meet the requirements if in critical field, otherwise undesirable.To say that method of the invention is more succinct, and system is simpler with the system of measurement handling capacity at present.
Description
Technical field
The present invention relates to wireless aps method for testing performance and detecting system in WIFI.
Background technology
Test WLAN（Wireless Fidelity, abbreviation WIFI）It is by wireless access node (Access
Point, abbreviation AP) and wireless network card composition wireless network.AP is commonly referred to as wireless access node or network bridge, and it is
As the bridge between traditional wired local area network and WLAN, therefore any one individual that wireless network card is housed
Computer（Personal Computer, abbreviation PC）AP is both transparent for go to share the wired local area network even money of Wide Area Network
Source.It is that data are transmitted by wireless signal between wireless aps and network interface card, weighing the leading indicator of wireless aps signal strength is
Signal intensity and handling capacity that network interface card end is shown.Therefore, when carrying out factory testing to wireless aps, it is necessary to detect wireless aps performance
When, the signal intensity and handling capacity shown generally by detection network interface card end.
At present, the system of test wireless aps wireless performance quality, industry common practice is between test AP and network interface card
Handling capacity.The method of testing based on IP device is generally used, with applied in network performance test instrument (Iperf.exe instruments to test).
Iperf.exe is a TCP/IP and UDP/IP performance measurement tool, using the teaching of the invention it is possible to provide network throughput information, is needed during test
It can be accessed mutually between two PC, and this two PC, Iperf.exe is separately operable on this two PC, with client kimonos
The form at business device end occurs, and thus tests out the handling capacity between this two PC by Iperf.exe.Iperf can test maximum
TCP and UDP bandwidth performances.Iperf has many kinds of parameters and UDP characteristics, can adjust as needed.Iperf can report band
Width, delay jitter and data-bag lost.
When testing the handling capacity of wireless aps, such environment has been used, 2 PC, 1 AP, one with netting twine.By wireless network
Card is arranged on PC1, and a PC2 is by netting twine and AP connections in addition, and such PC1 just connects upper AP by wireless network card, so that
Access PC2.Then the program iperf.exe of test handling capacity is separately operable on PC1 and PC2, gulping down for PC1 to PC2 is tested out
The amount of telling, such as Fig. 1, so test to the handling capacity between PC1 to PC2 be actually handling capacity between wireless network card and AP, that is,
The handling capacity of wireless aps.If handling capacity meets the requirements, then it is assumed that the wireless aps performance meets the requirements, and can dispatch from the factory.
In above-mentioned detecting system comprising shielded box, main test computer PC1 and from test computer PC2, equipment under test AP and
With measurement equipment STA.Wherein main test computer PC1 and equipment under test AP is linked together by Network transmission line, from test computer
PC2 is with accompanying measurement equipment STA to be linked together by Network transmission line.Test is completed by running Iperf.exe instruments, simultaneously
It is required that the testing time is more than 1 minute, the quality of the performance of equipment under test is judged by test data stream size.
Although test above can test AP handling capacity, the corresponding relation of test handling capacity is that signal intensity is better, is gulped down
The amount of telling is higher.But said system needs to be tested in the environment of a shielding, it is impossible to there is other wireless signals to be done
Disturb, therefore, the systematic comparison that the AP methods are used is complicated.
The content of the invention
The present invention measures the side that wireless aps performance is used in WIFI using the method for test AP handling capacities at present to overcome
Need to carry out in the environment of without Electromagnetic Interference during method, the more complicated deficiency of the detecting system used is based on there is provided one kind

Interior, if judging that described wireless aps to be measured meet the requirements in normal range (NR), otherwise described wireless aps to be measured are not inconsistent
Close and require.
Further, in above-mentioned WIFI in wireless aps method for testing performance：Described standard radio signal is by setting work(
The wireless network card transmitting of rate, the wireless network card and the distance of described wireless aps to be measured are certain.
Further, in above-mentioned WIFI in wireless aps method for testing performance：The wireless network clamping of described setting power
When receiving the wireless signal of described wireless aps to be measured transmitting, RSSI value is shown.
Further, in above-mentioned WIFI in wireless aps method for testing performance：Described normal range (NR) be tester according to
Design it needs to be determined that scope.
In addition, the system that the present invention also provides wireless aps performance detection in a kind of WIFI, including be connected with wireless aps to be measured
Master computer, be provided with accompany survey wireless network card STA；
It is described to accompany the transmission power for surveying wireless network card certain, described accompanying survey the antenna of wireless network card with it is described to be measured
The distance of wireless aps is certain；
Described accompanying is received including the wireless aps to be measured described in display survey wireless network card transmitting in described master computer
Wireless signal when RSSI value module.
Further, in above-mentioned WIFI in the system of wireless aps performance detection：Display institute is provided with described STA
Accompanying of stating surveys the module of RSSI value when wireless network card receives the wireless signal of described wireless aps to be measured transmitting..
Using the detection method and system of the performance of the WIFI wireless aps of the present invention, received by using wireless aps to be measured
When providing wireless signal, in RSSI signal strength values whether the mode within the scope of defined, it is not necessary to test environment is entered
Row shielding, makes test simpler, it is not required that carries out throughput calculation, makes test speed quicker.
The present invention is described in more detail with reference to specific embodiment.
