Future Wireless Communication Networks

无线通信网络已经彻底改变了我们的通信、信息检索和分发、娱乐和社会互动的模式。今天，全球蜂窝电话用户的数量超过50亿，行业收入在1万亿美元的范围内。未来数年的快速流量增长将受到新应用程序的推动，如移动的网页浏览、视频流、多人在线电子游戏和社交媒体。设计和运行一个网络，以资源有效的方式支持如此广泛的应用程序是一个艰巨的挑战。还有许多其他替代/补充无线产品和服务。这些网络包括局域网、个域网、城域网和区域网。这种广泛的选择满足了不同应用程序和部署方案的个性化需求。预计无线网络将在许多令人兴奋的新应用中发挥重要作用，例如个性化健康服务、远程医疗以及实时位置和上下文感知服务。

Wireless communication networks have revolutionized our modes of communications, information retrieval and distribution, entertainment and social interaction. To-day, the number of cellular telephone subscribers worldwide exceed five billion and industry revenues are in the one trillion dollars range. Rapid traffic growth in the coming years will be driven by new applications such as mobile web-browsing, video streaming, multi-player online e-games and social media. The design and operation of a network to support such a wide range of applications in a resource-efficient manner is a daunting challenge. There are also many other alternative/complementary wireless products and services. These include local area networks, personal area networks, metropolitan area networks and regional area networks. This wide choice caters to the individual needs of different applications and deployment scenarios. Wireless networks are envisioned to play important roles in many new exciting applications such as personalized health delivery, telemedicine and real-time location- and context-aware services.
