I’m currently in a situation where I’m responsible for optimizing the Wi-Fi network in a moderately sized office. The challenge is that some areas have weak or no signal, and we suspect there are dead zones. We need to precisely identify these areas to improve our network coverage.
What vendor Wifi are you using? Most controllers have the ability to import floor diagrams, place APs on the diagrams, and then it’ll give you a pretty accurate heat map. You can then use apps on phone/tablet/laptops to do a site survey and confirm.
