Smart power optimization for wireless transceivers

点击翻译按钮获取中文摘要

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.
