Hi, we would like to create a kind of game using 2.4Ghz emitters . The 2.4Ghz USB Dongle emits and the mobile phone detects the frequency + embed unique ID/code so we confirm if the person has been there ;-). No cheating !
Attached is our concept so we would thank you if someone can confirm we have chosen the right hardware before to buy.
Many many thanks ! Giom
