During the past decade, a major development in the telecommunications industry has been the explosive growth of the cellular telephone market. There are currently over two billion subscribers world-wide. In the US alone, the cellular service industry generates an annual revenue in excess of one hundred billion dollars. Even though the demand for cellular phone service shows no sign of slowing down, the industry is preparing for the next wave of innovation which includes wireless services such as high-speed data, audio/video streaming for web conferences, news, lectures, music, movies, etc. These different applications require inherently different Quality of Service (QoS) levels. The challenge is to design systems capable of supporting applications which are both appealing and affordable.

在过去十年中，电信工业的一个主要发展是蜂窝电话市场的爆炸性增长。目前全球有超过20亿用户。仅在美国，蜂窝服务产业产生的年收入就超过1000亿美元。尽管对蜂窝电话服务的需求没有显示出放缓的迹象，但该行业正在为下一波创新做准备，这些创新包括无线服务，如高速数据、用于网络会议的音频/视频流、新闻、讲座、音乐、电影等。面临的挑战是设计能够支持既有吸引力又负担得起的应用程序的系统。
