Abstract:To promote research on wireless and mobile communications, 2009 Huangshan Symposium on "Green Wireless Technology and System" was held during 12~13 June, 2009 in Huangshan, Anhui. At the symposium, five major speeches by professors from famous universities analyzed the cooperative distributed MIMO system to efficiently reduce transmitting power as a novel scheme of green networks, proposed an idea of green wireless network, especially content aware soft real time (CASoRT) transmission design, for reducing cost and saving energy, expounded on BS reconfiguration based on the cognitive technique for remarkably saving power, discussed the change from achieving highest transmitting data rate to seeking best power efficiency for future wireless and mobile communications, and advanced an environmentally friendly efficiency function for assessing cellular network design for green communications. These discussions reflect the research and development results and ideas for green wireless and mobile communications.
Keywords:green wireless networks  wireless and mobile communications  distributed cooperative communications  content aware soft real time  cellular design for saving environment
