             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.


           Example senarios : Railway /airline reservation enquiry over SMS ...would usually be
                              beprone to congestion .....bandwidth etc.

                              constructions several services can be made accessible ...say PNR enquiry etc.

                              Similarly much on the lines of Maps(GPS) ...for such constructions
                              ...a internal map ...using downloadable maps ...say on the lines
                              of the HTML image-maps ...a sequences of such ...maps ...zooming in
                              offering directional guidance of services available with in such public
