Realistic and Representative Environment: Real House, Real Client Devices
A lab environment with an anechoic chamber may sound like the best option to run Wi-Fi performance tests, however, it was already proven many times that Access Points that score the best in a lab environment do not always score as well in a real life environments. To obtain realistic results, Excentis runs all tests in a real house.
Performance results may also differ heavily depending on the type of client device that is used for the testing. Again to obtain representative results, Excentis uses a mix of real client devices (representing the majority of client devices that is currently using Wi-Fi):
- Apple (iPad, iPhone, MacBook)
- Android based tablet and smartphone
- Windows laptop
The performance is measured by using special apps that work together with our ByteBlower traffic generator/analyser. The measurements are done with the client devices on different locations and with different orientations, chosen as such to have a coverage ranging from very good to very poor. For half of the measurements the Access Point is not on the same floor as the client devices, so the effect of the ceiling/floor is also being assessed.
To allow performance comparison between devices, even when there was a long time gap between the measurements, it is of utmost importance to do the tests in a long-term static environment.
Our test environment is interference-free: there are no other houses in the neighbourhood that may cause uncontrolled interference!
Long-term static test environment: nobody lives in the house, the furniture doesn't move, which is crucial to have reproducable measurements with Wi-Fi
The measurements are fully automated and done by a robot, this to remove the influence of human presence and to avoid human errors. Fully automated measurements also allow to do sufficient measurements in a cost effective way.
