Smart power optimization for wireless transceivers

无线通信的发展遵循两个不同的方向：一个侧重于星形网格架构，具有昂贵的基础设施和“低成本”移动终端（例如4G蜂窝网络）；另一个基于廉价的点对点通信设备（例如WLAN、无线传感器网络（WSNs）和RFID）。蜂窝通信是过去十年中最具活力和最富有成效的市场之一，2011年的手机销量超过170万部，预计2012年的销量将达到类似水平。与此同时，无线传感器网络代表了为自动化和环境监测量身定制的新一代无线通信，预计在未来10年，2021年将从4.5亿美元增长到20亿美元。

The evolution of wireless communications follows two different directions: one focused on star-mesh architectures, with expensive infrastructure and "low cost" mobile terminals (e.g. 4G cellular network) and one based on cheap devices for peer-to-peer communications (e.g. WLAN, Wireless Sensor Networks (WSNs) and RFID). Cellular communication represents one of the most dynamic and fruitful markets of the last decade with more than 1.7 million of mobile phones sold in 2011 and similar volumes expected for 2012. Alongside this consolidated reality, Wireless Sensor Networks represent a new generation of wireless communication tailored to automation and environmental monitoring, with an expected growth from 450M$ up to 2B$ in the next 10 years 2021.
