We need to develop a location-aware application using wireless technology and PDAs. The end product would be a prototype that would enable users who own PDAs and who are within various hotspots in Singapore to obtain information and comunicate The application would allow users to log on and sleect the kind of information such as market information, product information they wish to receive. #Some example qns: 1.) What kind of devices or in fact what do i need (hardware, software..etc.) so that I can locate the position of the users.. Like for example, let's say that user's are at orchard road.. they would like to be sent information about the hottest furniture deals in orchard road and stuff.. But the question is how am I to know that the users are at that place? Do we need to implement GPS at all? Please be more specific about the devices needed and stuff. 2.) I personally am very confused about HOTSPOTS and GPS.. The thing is that.. sinc we set hotspots.. don't we already know the place where the customer is, even without GPS??? 3.) What kind of language can be used to develop this application? Will the application work on all PDAs? What langauge would you recommend to program such an application and why? And what sort of application would be required with the development of the application using the language you specified. 4.) Database, where should the database reside. What kind of database would be used for PDA application typically? SQL? ORACLE?? 8.) Give me an example on a typical scenario(step by step) in which the users get location-based information on their PDAs. For example(i don' t know if this is right): 1.) connect to the GPS receiver 2.) connect to the wireless lan 3.) login to the system, system will communicate with GPS to retrieve current cords, send cords to the web application. 4.) Web application will send back information near the user's location. I must have missed some other steps.. so just give me a typical scenario. 9.) Do you have any information or diagram that I can refer to so that I can be clearer of what you mean and so that I can have a better understanding on wireless technology and PDAs. Thanks Aaron
