In the Gigabit era in Wi-Fi connectivity, upgrading to the 802. 11ac standard represents the next step in wireless evolution. Many enterprises looking to break the 1-Gbps Wi-Fi speed barrier face the challenge of replacing existing 802. 11n access points. While 802. 11n operates on both 2. 4 GHz and 5 GHz frequency band, 802. 11ac predominantly uses the 5 GHz band which by its nature traditionally reduces coverage when compared to 2. 4 GHz. This led to costly and time consuming efforts for installers to ensure that sufficient APs were installed to give complete coverage.
