Mobile Development › key terms and concepts Unstructured Supplementary USSD works on all existing GSM phones. It provides session-based Service Data communication, enabling a variety of applications. (USSD) World Wide Web W3C have been the leaders in web standards and best practices for a long Consortium (W3C) time and have now expanded to include the mobile web. This refers to the most often used modern day keyboard layout. Regarding mobile phones, it refers to devices with a full keypad. The name comes QWERTY from the first six keys appearing in the top letter row of the keyboard which together spell QWERTY. 6.3 history There was a time when browsing the Internet using a mobile phone was as pleasant as submitting tax returns. Mobile browsing and development has progressed in leaps and bounds, with contemporary phones capable of handling features normally reserved for desktop browsing. Although the first mobile browser was developed in 1994 - as PocketWeb for Apple Newton - it was only in 1998 when Wireless Application Protocol (WAP) became the industry standard that mobile browsing truly took off. Very few mobile handsets actually supported WAP, and even fewer websites were formatted for mobile browsing. So, the concept of anytime, anywhere Internet access became firmly entrenched in the developing mobile community as the first generation of access (1G) was born. Using the Global System for Mobile Communication (GSM) network, developers quickly began formatting websites for mobile devices. Applications like MXit , launched in 2003, took advantage of low data costs to transfer instant messages. At the same time, phones started looking less like construction bricks and more like the standard numerical keypad phones used in the majority of countries today. In the early 2000s, feature and smart phones began utilising the newly launched Enhanced Data rates for GSM Evolution (EDGE) network as part of 2G technology – a technological expansion of the original GSM network. Developers also began utilising EDGE for content heavy websites and small file downloads. As the use of 2G phones became more prevalent and people began to utilise mobile phones in their daily lives, it became clear that the demand for data services would soon need overhauling.142
