I have an open wifi hotspot and a web server and I'm trying to set up a kind of proximity marketing. Basically I'd like to adjust the content of the web pages sent by my web server providing specific information according to the geographic position of the device that is running the web client.
This should allow a user to connect his device and surf to a static URL and then, when walking around the hotspot area, read special contents each time he walks near some places (i.e. a statue).
As I said, I have full access and can manage both the wifi infrastructure and the web server, but I need to accomplish this using wifi only (i.e. without involving bluetooth, umts or other technologies).
I've heard about WPS but I can't understand how that works.
Any pointer or suggestion is really appreciated.
Thank you!
WPS may not be useful, as it only works within 10-20 meters.
Have you considered QR codes? There is a local museum that uses them very effectively for a guided informational tour which may be close to your application. You could serve adds in addition to whatever info you are providing.
You could also rent tablets with QR capability that are preconfigured for your network. It could possibly generate revenue for your exhibit and might provide you with sponsorship opportunities.
