Experimental Assessment of Wireless Performance Under an Elevated Noise Floor

Debugging wireless communication problems in a field installation is difficult, disruptive, and costly. Roaming problems reported after the installation of wireless access points are hard to reproduce since the radio-frequency (RF) environment at an end-user facility such as a data center, hospital, industrial environment, etc. can be uncontrolled, dependent on the radio traffic, the time of day, the location of potentially mobile scatterers, etc. This disclosure describes techniques to reproduce the RF environment found in a given real-life scenario in a controlled RF environment such as a semi-anechoic chamber or a reverberation chamber. Experiments can be easily conducted in order to determine the root cause of failures and to develop and test = solutions
