Re: [MCN-L] Tapping the MCN Brain Trust

[Nik Honeysett]

Thanks again for the thoughts and insights. This is a city park, and anybody on 
this list who works with a city on landmark spaces will know I'd have to offer 
up my first born to do any kind presence detection, they’re as bad as art 
museum directors when it comes to putting things into spaces where they 
shouldn’t be. How do you set up a line of sight wireless bridge when you can’t 
have anything in sight...

Right, zoning in on an accurate measurement is my goal, and that’s a good point 
about focusing on smaller scale situations that might inform the larger number.

I have a question, if you have visitorship numbers from other sources, is it 
possible to simply find out the error windows on those numbers?

You mentioned an event with 350K people. Hopefully there are other such events 
that have 'supposed" numbers associated with them. is it possible, on these 
smaller scales, to find out the deviation from wifi numbers? That would at 
least allow you to see if your numbers agree with or wildly deviate from the 
75% number from the UK survey.

Furthermore, can you use sampling tecniques to do this on the cheap? I'm sure 
you know more popular sections VS not. In fact, you could use existing wifi to 
tell you this. so, in certain areas to do the necessary leg work, but then use 
that to feed a larger model to validate and/or debunk your 12M number.

In all seriousness, if your goal is not production, but rather limited data 
collection, is it out of the question to put conventional (even battery 
powered) presence detection devices in a few key places where you have at least 
one other form of ground truth e.g. a camera?

My goal with any/all of these suggestions is to simply find out, eventually, 
which metric has higher accuracy.

I am happy to be wrong, but with that many "bags of mostly water", I just don't 
buy that a wifi-based counting system that relies on back-scatter and 
reflection counting, with some phase calculations thrown in, is going to be 
worth anything other than maybe order of magnitude.

Take care,
Sina

Sina - that took 3 minutes? You’re awesome. Many thanks...

Bruce - this is kind of thing I’m looking for - many thanks.

Obviously, my friend is me. The accepted park visitorship is 12 million - no 
idea where this comes from. Institutional attendance (museums and zoo) reports 
in at about 6.5 million but there is double, triple and quadruple counting 
hiding in these numbers. I’m interested in whether the 12 million is accurate, 
so yes, interested in the joggers, dog walkers and picnickers, etc. I’m 
inclined to think the 12 million is inflated significantly.

Its Ruckus equipment and we tried counting all devices in the area, but the 
differential between users on the wifi and devices wasn’t very big, so I didn’t 
trust it. However, if 75% of smartphone users are looking for free wifi (I 
thought it would be much lower), then maybe I should take another look at that 
number.

We serve an average of 100K users per month on the wifi and tomorrow and 
saturday is our signature event when we’ll “officially" see 350K people in the 
park - no idea where this number comes from either, but like to support it it 
or debunk it.

Thanks for the thoughts and data much appreciated. And while I’d love to use 
some drones, we’re on the SAN flight path and only a mile from the airport.

Nik,

This seems like a question that Google would give to you during a job 
interview! Fascinating to see the MCN Brain Trust put it’s thought process to 
work!
