This research report analyzes the expanding competitive landscape of fixed wireless internet and its impact on traditional wireline providers across the United States. While fiber and cable companies historically dominated suburban markets, fixed wireless has emerged as a significant rival, particularly in areas where high-speed physical infrastructure was never built. Data reveals that this technology now provides a new choice for 44 percent of American addresses, often breaking up existing monopolies in both rural and densely populated urban centers. However, the study notes that the competitive threat of wireless service is currently limited to the 100/20 Mbps federal benchmark, as it often fails to match the higher speeds offered by cable and fiber. Ultimately, the source serves as a strategic guide for internet operators to identify where their market share is most vulnerable to wireless alternatives.
