The RF spectrum is limited, with mobile users demanding an increasing amount of capacity for video and other high-bandwidth applications. In environments such as stadiums and arenas, providing consistent and reliable Wi-Fi access can be challenging, especially as more mobile devices are packed into a confined area and high or nonexistent ceilings for access point installation. The 3500p is designed with custom configuration settings and narrow-bandwidth, high-gain external antennas to provide targeted coverage for high-density deployments. This special system of directional antennas and power settings allow an organization to deploy more access points closer together, enabling more capacity, lower co-channel interference, and a better user experience. Because of the unique antenna and power settings, FCC regulations require the Cisco Aironet 3500p Access Point to be installed by a certified professional.
