This paper studies the impact of receiver selectivity mask selection on interference estimation for fixed microwave receivers operating at 6 GHz band. We consider 802.11 wireless LAN (WLAN) as the interferer and fixed microwave receiver as the victim. Two receiver selectivity models, such as Nyquist filter and ideal brickwall filter were compared with more conservative case when transmission mask are used as a receiver selectivity. The comparison has been done based on the numerical estimations of maximum transmission power for WLAN such that the level of experienced interference-to-noise (I/N) ratio at the victim receiver does not exceed the predefined threshold. Numerical estimations show that selecting the proper receiver selectivity model at the victim receiver may have critical impact for per megahertz power estimation compared to the channel-based option. As expected, selecting Nyquist filter model leads to more realistic and less conservative results compared to brickwal and Tx mask models.
