The shortcomings of earlier Wi-Fi generations in high-density settings will be addressed by Wi-Fi 7 (IEEE 802.11be), which is poised to transform wireless communication. Wi-Fi 7 delivers previously unheard-of performance lower latency and more dependability thanks to new modulation methods a broader channel bandwidth and upgraded features like MultiLink Operation (MLO). In this paper author discusses about Wi-Fi 7 seeks to address the particular issues of congestion and interference that arise in high-density settings like stadiums, conference centres, and smart cities. The technological developments of Wi-Fi 7 its effects on high-density network situations and its possible real-world applications are all examined in this study
