The issue of 6GHz interference has garnered significant attention in recent years with the introduction of WIFI 6E. This presentation explores the tangible impact of 6GHz microwave links' performance in the wake of WIFI 6E's launch. It underscores the urgency to proactively predict and address the potential degradation of link fade margin, rather than adopting a wait-and-see approach.

The significance of 6GHz microwave links within critical communication networks cannot be overstated, making any interference-induced performance decline utterly unacceptable. This study delves into creating WIFI 6E radio and antenna data files, adhering to their specifications, to assess the interference levels transmitting from WIFI 6E routers.

Key takeaways:
See select real-world case studies in highly populated Tampa Bay area.
Review a few scenarios involving WIFI 6E routers surrounding a 6GHz microwave site with multi-directional microwave radios.
Understand that the outcome of the interference calculation significantly impacts the performance of 6GHz microwave radio links.
Examine how these practical instances serve to reinforce the findings and implications of the study.
