I need basically a set of PCBs and related software. PCB involves catching the GSM/CDMA pilot signal from mobile phone(no GPS system)- detecting the exact location of mobile. This will be used in shopping malls(big book shops, shopping malls, lodgings hotels ) . When a customer enters the place. his presence is detected(the point of entry and exit, i.e. the point from where the dection of his location starts and ends can be set up during installation). His location is constantly updated. When he enters the shop,his mobile gets an SMS "Welcome to shop" and "menu of services the shop provides." the user can browse through services and enter his requirements in mobile. when user enters his requirements, then the message is transmitted from mobile to PCB, from PCB to win32 system. (The windows system knows the location of each item where it is placed. This database will be updated by shopkeeper on regular basis) on receiving the product query from mobile, the Windows server searches the product in database and its location, in which corner and rack and communicate the details to PCB. PCB can guide the mobile to the item, whwere it is placed.
1> book shop- the mobile gets sms, we have "categories" of books. browse your category. when he enters a particular book, he guides where the book is.
2> Similarly in shopping malls
3> lodgings- mobile gets sms "we have this types of rooms and rent for them, select category". when he selects category room is locked for him. then he is guided to payment counter. after making payment, he is guided to room. in the room he gets aan sms for room service facilities- menu. he can select from services any time
4> restaurants: once mobile user enters the restaurant- he gets menu of food items. he chooses the menu . places an order. the system knows where exactly person is sitting, table. he gets his order intable
