my friends from hivenetworks are doing that sort of thing. they
are doing much more but they could also create such a simple
here an excerpt from this text
On 10 light poles in the centre of Southampton on Above Bar
street weather proof little boxes have been mounted which
contain repurposed commercially available hardware. The unique
hard- software combination implemented by Hivenetworks is
playing soundfiles in a loop on FM radio on 89.0 MHtz. The very
low powered USB FM transmitters are said to have a range of
about 10 to 15 meters. Thus, around each lighhtpole in a radius
of 30 meters approximately you can hear one particular radio art
piece created by me with excerpts from the Oral History Archive.
The boxes also scan the surroundings for mobile phones with the
bluetooth function on. Asking the carrier of the mobile phone to
accept a message first, a short bluetooth text message is
transmitted announcing the node, the frequency and its content.
If you want I can get you in touch
