Imagine a scenario where I have more than 30 APs, each about 60 feet average part, mounted at about 35 ft high (ceiling is 40 feet and the APs will be lowered 5 to 6 feet) and 5GHz power set to medium and 2.4GHz power set to low. Can I expect some kind of conical / inverted soccer type of coverage? With no DFS channels available in North America, we only have 9 channels of 20MHz width. The primary use case is Smartphones in a marketplace.And I have no idea as to how the radiation pattern looks like for these APs so as to minimize the energy being sent higher up space. I will assume that as it is standard with most built-in antenna designs these days, Tplink antenna also have built-in electrical or mechanical down-tilt to help steer the coverage downwards.
If indoors EAP225 was available withe external antenna, I would have gone for patch antenna to restrict the coverage to smaller area and to help better uplink signal from the smartphones.
Anyone having installed APs on high ceilings, please share your experience.
