We've had the solution live in stores for years without any issue. Our algorithms can clean up and filter out unreliable data, based on all of the other data we have, from other APs, from previous data etc..

If they re-fit the WiFi, which they might spend a month doing once every 5-10 years, it would need a re-survey, which could take 1-2 hours. But thankfully no new infrastructure.
