It’s worth reaching out to these folks:
<http://www.ece.ucsb.edu/~ymostofi/HeadCountingWithWiFi>>. They may be able to
give you the coarse estimator that you’re looking for even if they’ve patented
their refined version.
Aside from that, This survey out of the UK in 2014.
<http://purple.ai/latest-survey-people-use-wifi-public-places/>> did a survey
which indicates ~75% of people are looking for & using wifi. (mileage may vary,

carrier network traffic will be offloaded to Wi-Fi. And Pew Research last year
indicates that 68% of adults have smartphones.
(and another study that I can’t find at the moment suggests that 90% of
smartphones have Wifi which seems low to me, but we’re quibbling at this point).
So. 2/3 of the population have smartphones, 75% of those smartphone users are
looking for free wifi, stringing together a few studies and looking at some
That gets you somewhat close for estimate purposes.
And then validate with a small tracking study and / or the UCSB folks in the
