Core Viewpoint - The rapid growth in Wi-Fi usage is leading to a potential exhaustion of the 6 GHz frequency band, which could negatively impact the performance of applications relying on Wi-Fi connectivity [1][3][10]. Group 1: Research Findings - CableLabs conducted a study simulating a 12-story residential building with 12 units per floor, analyzing Wi-Fi performance under peak usage conditions [1][5]. - The study found that approximately 30% of users in the simulated building experienced increased one-way Wi-Fi latency (over 10 milliseconds) and a packet loss rate of 2% or more [1][6]. - The analysis indicates that as demand for Wi-Fi continues to grow, the 6 GHz frequency band is at risk of being exhausted, leading to degraded performance for critical applications like video calls and online gaming [3][6]. Group 2: Policy Implications - CableLabs has been advocating for lawmakers to ensure the availability of more unlicensed spectrum to maintain Wi-Fi speeds before economic impacts arise from slow Wi-Fi [2][3]. - The organization emphasizes the urgent need to preserve current unlicensed spectrum resources and to allocate more to support the increasing demand for Wi-Fi in high-density environments [3][10]. - The findings highlight the importance of the 6 GHz spectrum for maintaining reliable Wi-Fi performance for consumers and businesses in the U.S. [10].
