Measurements Of The Emission Parameters Of A Wimax Bts Under Interference Conditions

Within this paper the authors intend to measure and evaluate the parameters of a WiMax BTS when different interference conditions are existing within its operating area. The measurements were performed in laboratory conditions, in the semi-anechoic chamber. The effect of variable intensity disturbance interference on the emission parameters of a WiMax base station were measured and analyzed. As a result of these measurements, several situations were analyzed and a number of interesting conclusions were drawn.These measurements have been developed in order to evaluate the effect of a of disruptive interference on the quality of the transmitted signal, as well as the importance of detecting, measuring and analyzing the interference effect on the transmitted signal in different use-case scenarios. The narrowband disturbance signal, with variable intensity, was generated on the 3.623 GHz frequency with the SHE 03 Rohde & Schwarz signal generator. Parameter measurements and spectral evaluations were performed with the Anritsu Master Spectrum 2723C spectrum analyzer, tuned to the frequency 3.623 GHz, using transmission and reception antennas in the respective band. An Airspan MacroMAXe-4RX base station, 3600-3700 MHz frequency band, with 5 MHz bandwidth, was used to perform the tests.
