: : : Hi : : : I'm completly new to both mobile tlf. tecnology and to WAP. : : : so, how to conect handheld device(mob.tlf.) : : : with the gateway, do I use tlf.nr, url or..?? : : : What do I need on the server/gateway side to be able to recive : : : the messages, must I conect som kind of antenna or what?? : : : Pleace fill me in with te-spoon : : Hello Tore : : I'll try my best to explain how wap works : : First of all, WAP is made to be as similar to the internet architecture as possible. : : All content that you access from your wap browser is stored on a web server. : : The content on the server is addressed using a url, e.g http://www.mobic.com/index.wml (does not exist, yet) : : Normally, a wap phone will be preset to load a standard page, the same way as an internet browser : : Initially I believe that the operator wap home page will be the default start page : : The startpage will then point to other services, using url's to address other services (on the same or another server) : : If you want to access other services, you will be able to choose another url. : : I suppose all wap phones will enable the user to manually input url's : : Entering a url from a phone is not easy, and I believe that most wap service providers will let you use the internet to personalise your services : : The result of the personalisation will then be available as a list of services on your phone : : When you use the service on the phone, you will not see the url's, only the service names and hierarchy : : To access wap services, you will use some communication to the wap gateway : : Wap supports many carrier technologies, among them are SMS and GSM data (and similar carriers for other wireless networks) : : If SMS is used, the browser will compress your request using WAP compression techniques. : : The request is then sent to the gateway, which translates the request to a standard http request, and send it to the web server using the url : : The response is sent back to the gateway, which encode the content using SMS, and send it back to the WAP phone, which displays the result : : If GSM data is used, a connection is established before the dialog between the client and gateway/server is started. : : On the terminal side of the gateway, wap protocols are used : : On the internet side of the gateway, standard internet protocols are used : : The data connection is set up automatically as a result of the request from the user. There will normally not be any manual setup. But, different terminals will handle this different. : : For GSM, there will be a packet network called GPRS coming into operation next year : : GPRS will be perfect for WAP, with GPRS you do not need to set up a connection, packets will be sent and received whenever needed. : : I hope this explanation answers some of your questions. : : I have added a link to a short system description of wap : : Regards : : Tore : : : Many regards : : : Tore
