Opportunity: Radio frequency (given the context of range) exploit for Query ...enquiry services
             ...a publicly accessible medium.


             Given that most modern mobile handsets offer selection of a network (RF)
             and also can handle FM radio kind of services ...utilization of a spectrum
             low-range for a range of services ...understanding of WLL also the wifi in
             the context would be helpful.

             refer to the document "Opportunity_ticketing_reservation_systems.txt"


           Example senarios : Railway /airline/cinema/auditorium/stadiaa reservation enquiry 
                                     over SMS/IVR systems ...would usually be beprone to congestion 
                                     ...bandwidth etc.

                              Several or a range of services can be made accessible within the
