hi, apologies in advance! (always a good way to start!)
i would like to track mobiles (creep status set to maximum), and i think i can do this through wifi. most people with smart phones have them set to normally transmit / receive.
[why would you wan to do that you creep?]
well, promotional tracking is one usage. my brain fart says that if i have a square room, and 4 tables. each table has an item on it and i want to know which item people are most interested in looking at. near each table is a (ready for the trademarked name?!) wifi pinger.
in my head, the pinger sends a request / ping out every 10 seconds, and the phones that return a ping (yes / no doesn't matter, just the existence) and records the output. after a few hours, the unit with the most pings sends a clear message about how many pings it receives (length of time) and unique pings (individuals)
(see not soooo creepy!)
can wifi ping, without interrupting peoples phones? not asking for handshakes, etc, but just to see if the ping is returned? can this return be identified individually? mac address / phone name etc? are there massive breaches of laws in this process?
anyway, thanks for listening to the brain fart!
