The WPlus license is suitable for environments using OfficeExtend Access Points (OEAP), which allows employees to work from home with a seamless connection to the corporate wireless network. The WPlus license enables features such as advanced security and increased scalability for remote workers. References:

For a high-density WLAN environment like a 10,000-seat auditorium, placing APs under the seats can take advantage of human attenuation and maintain the aesthetics of the room. Human bodies absorb Wi-Fi signals, and placing APs under the seats helps in mitigating this effect by having the signals emanate from among the audience, rather than from above where the signals would have to pass through the audience, resulting in signal degradation.

When conducting an outdoor bridge site survey, weather and the Fresnel zone are critical criteria to consider.
Weather can affect signal propagation and the reliability of the wireless link, while the Fresnel zone relates to the elliptical area around the line-of-sight path between transceivers, which must be clear of obstacles to ensure a strong signal.
