Based on wireless network card testing apparatus provided by the invention, can realize radio-frequency (RF) index, the network interface card flow, the test of OTA, before testing, need the wireless network card testing apparatus, wireless network card, system simulator connects into a complete test link, as shown in Figure 2, wireless network card to be measured is plugged on the wireless network card interface module that the wireless network card testing apparatus externally provides, after powering on, the wireless network card testing apparatus automatically performs system initialization, after finishing, initialization enters wait state, after pressing the networking button, wireless processing module in the wireless network card testing apparatus automatically performs web search, and the test link of automatic foundation and system simulator, after test link foundation finishes, can begin the index performance, the test of aspect such as flow and OTA.
The test of radio-frequency (RF) index:
When adopting wireless network card testing apparatus provided by the invention that the radio-frequency (RF) index of wireless network card is tested, require the radio frequency part of wireless network card to be measured to have radio frequency test interface, for network terminal analogue devices such as connected system simulators, as shown in Figure 3, concrete testing procedure is as follows:
Step 301: connect wireless network card testing apparatus and network interface card, system simulator is placed test position, make it can form complete test link physically, as shown in Figure 2;
Step 302: open system simulator and wireless network card testing apparatus, system simulator and wireless network card testing apparatus are after the initialization of finishing separately, automatically enter test mode, system simulator is waited for connection request, and when receiving the connection request that the wireless network card testing apparatus sends by wireless network card, Radio Link between foundation and the wireless network card testing apparatus is to make whole link be in normal operating conditions;
Step 303: the downstream signal of system simulator is set, the parameter of reference channel and propagation channel;
Step 304: switching on and shutting down parameter, initiation parameter, networking parameter of wireless network card testing apparatus etc. are set.
Step 305: system simulator continues with the maximum power transmission instruction, with the average power of test network interface card;
Behind UNICOM's network, system simulator continues with the maximum power transmission instruction, after the wireless network card testing apparatus receives instruction, can return instruction give system simulator.From this signalling interactive process, network has carried the received power of network interface card and has given system simulator, and system simulator reads each power, draws average power according to the measuring and calculating of inside.
Step 306: every radio-frequency (RF) index of test network interface card, as transmitting power, switching on and shutting down power, spectral characteristic etc.
The value of the switching on and shutting down power of network interface card for measuring in the moment of startup and shutdown.The spectral characteristic of network interface card can be read from system simulator.
Step 307: interrupt as networking, the wireless network card testing apparatus proposes break warnings, and carries out from being dynamically connected network function.As successful connection, then forward step 306 to; As automatic networking failure, then forward step 302 to.
The network interface card flow rate test:
Step 401: connect wireless network card testing apparatus and network interface card, system simulator is placed test position, make it can form complete test link physically,
Step 402: open system simulator and wireless network card testing apparatus, make whole test link be in normal operating conditions;
Step 403: the downstream signal of system simulator is set, the parameter of reference channel and propagation channel;
Step 404: system simulator continues with the maximum power transmission instruction, and sends data with the maximum stream flow of network interface card nominal;
Step 405: the flow that system simulator statistics network interface card receives.
Step 406: interrupt as networking, the wireless network card testing apparatus proposes break warnings, and carries out from being dynamically connected network function.As successful connection, then forward step 405 to; As automatic networking failure, then forward step 402 to.
The test of OTA (Over The Air):
Step 501: wireless network card to be measured is inserted the wireless network card testing apparatus, do the as a whole antenna darkroom that places, determinand integral body is linked to each other with system simulator;
Step 502: open system simulator and wireless network card testing apparatus, make whole test link be in normal operating conditions;
Step 503: the parameter of setting and Adjustment System simulator,
Step 504: system simulator continues to send instruction, integral body to tested network interface card and wireless network card testing apparatus formation averages radiant power (Total Radiated Power, TRP), average radiation sensitivity (TotalRadiated Sensitivity, test TRS);
Step 505: interrupt as networking, the wireless network card testing apparatus proposes break warnings, and carries out from being dynamically connected network function.As successful connection, then forward step 504 to; As automatic networking failure, then forward step 503 to.
Because the energy consumption of wireless network card testing apparatus is less, and built-in big capacity rechargeable battery or charging electroplax, so can support the testing time of sufficiently long TRS, need not consider standby time and cause the problem that test is interrupted, also need not consider owing to having connected the rotation inconvenience that external power supply causes, the problem of influence test.
Because the capacity of network interface card carrier is very little, in the test wireless network card, need not existing test macro is improved.
The above is preferred embodiment of the present invention only, is not to be used to limit protection scope of the present invention.
