and who pays for the fm licensing?
The transmitter are very low power and I think licensing issue will net be there (may be i am wrong).
this issue was discussed at length and it wont be leagul for us to do such a thing. and the problem from the point of views of audio interfacing is to see from which way a blind person is approaching the post and weather to give him a "go to left" or "go to right ". there are other problems too as such a fm system will not provide for any interaction. for example I want to decide out of the 10 places where exactly I want to go. regards.
The sample message will be, // Welcome to XYZ square. If you are coming from ABC then take left turn for DEF, right turn for GHI...
If you are coming from JKL then take left turn for GHI, right turn for DEF... And so on. //
Remember, cost is a major factor, for installation or the user.
Secondly this will be helpful for the other people (not blind) who are new to that area.
