Published:

This essay has been submitted by a student. This is not an example of the work written by our professional essay writers.

A web application is an application that is hosted in browser-controlled environment over a network such as the internet or intranet. they consist of static web pages or they can be more advanced and consist of JSP files, Java servlets other web resources that include image files, compressed archives. Web applications are deployed within a web server, such as Resin. Each web application has a corresponding URL. URL has a unique name or path that identifies it within the server. The URL begins with the part needed to identify the server, followed by the web-app path each server has one webapp that is the default, it is the one that is used when no webapp-name is provided.

Mobile applications are developed using WML, WMLScript and WBMP with a server. For dynamic WML applications, developers used ASP, JSP, PHP, etc. Still these applications serve WML. The Mobile Devices includes Cell Phones, Palm Pilots, Pocket PC's. Few of these devices support WML,or HTML and few support both WML and HTML.

Microsoft introduced a revolutionary application .NET framework. It includes ASP.NET for Web development. It supports traditional Web clients such as IE and Netscape as well as mobile clients such as Phone.com, Pocket PC's. ASP.NET applications can be developed on any .NET enabled language such as VB.NET, JScript, Managed C++, C#

2. OVERVIEW AND BACKGROUND OF 3G TECHNOLOGIES

3G stands for third Generation the term used to describe the latest generation of wirless mobile services including fast data ,improved quality voice and, access to the Internet and multimedia services. The ITU is working with industry bodies from around the world, has defined standards for 3G systems under the IMT-2000 (International Mobile Telecommunications-2000) program.

The first-generation phone was GSM with EDGE; the second generation phone added UMTS with 3.6 Mbps HSDPA; the third generation adds support for 7.2 Mbps HSDPA downloading but remains limited to 384 Kbps uploading as Apple has not implemented the HSPA protocol.

The AT&T 3G network uses HSDPA/UMTS technology which offers variety of rich wireless services.3G wireless technology is perceived as accomplishing higher speeds for file downloading, web browsing, or performing other wireless Internet-related tasks. The family includes technologies recognized by consumers such as GSM, EDGE and WiMAX.

Including many 3G network enabled phones, iphone has been a breakthrough in 3G enables devices by introducing a innovative mobile phone, a widescreen iPod, and an advance Internet device. It is a smartphone designed by Apple Inc. It works as a digital camera, a PMP which similar to video ipod, and an internet client with email, web brwosing and WiFi connectivity, and landscap keyboard

3. USES OF 3G WEB TECHNOLOGIES

If you're not within a clear line of sight to a GPS satellite, iPhone finds you via Wi-Fi. If you're not in range of a Wi-Fi hotspot, iPhone finds you using cellular towers.

7.TECHNICAL APPROACH

The main objectives of the 3Gweb are to:

7.1 Improve Usability of European Mobile Web Platform:

Making Web access from a mobile device as simple, easy and convenient as Web access from a desktop device. Web access on a mobile device should be as natural as using a mobile device for making a telephone call.

7.2Improve Interoperability of European Mobile Web Platform:

To eradicate the problem of European mobile web systems incompatibilities, often caused by lack of standards conformance.

7.3Improve Integration of Mobile Web Applications with Networks

Work package1 (Outreach): Serves to disseminate the results of W3C's "Mobile Web Initiative" to a European audience. The dissemination plans include press releases relating to the "Mobile Web Initiative". W3C organized European seminars, talks by W3C team members at events as well as the development of information brochures and posters. The effectiveness of the outreach efforts will be tracked by collecting press clippings that mention results of W3Cs "Mobile Web Initiative", as well as by tracking and analyzing the type of attendees at 3GWeb funded events and talks.

It has a tremendous impact on the realization of the goals of the 3Gweb as it provides a level-playing ground for ensuring improved interoperability of European Mobile Web platform, usability of European Mobile platform, and integration of Mobile Web Applications with Networks.In this way, ideas gathered from major stakeholders in this area, are incorporated and documented to become a standard that every stakeholder must conform to.

8. SUMMARY

With mobile access, approaching diffusion in many European countries,operators are relying on data services to generate growth. Mobile operator around the world are upgrading 2G GSM network to 3G networks to provide faster data services with higher speed. 3GWeb has considerably enhance, reliability , usability, integration of European mobile Web technology.

iPhone is one of the provider of 3G wireless web which has come up with its innovative ideas by integrating mobile and 3G network on one platform,its is providing including fast data ,improved quality voice and, access to the Internet and multimedia services. Apple iphone. It works as a digital camera, a PMP which similar to video ipod, and an internet client with email, web brwosing and WiFi connectivity, and landscap keyboard. In the analysis of the 3G web, a consideration of the system requirements is paramount. This comprises the functional requirements, non-functional requirements, and domain requirements of each of the sub-system( web application, operating system, and hardware). The mind blowing functionality is supported by iPhone OS(Operating System) which is a powerful tool for serving a platform for Safari web browser to integrate the web application with 3G networks including WiFi.

Based on Wideband CDMA (WCDMA), which has emerged as the 3G technology of choice for GSM network evolution worldwide. Integrated with W3C's Mobile Web Initiative, 3GWeb will perform activities, training and development bringing together mobile Web stakeholders beyond 3G.
