A team of researchers at the University of Southern California collaborated with Samsung to develop a model that interprets how fast wireless devices can capture and store energy to demonstrate that complex networks can be run on renewable energy sources.
Necessity But Insufficiency of Interoperability Measures to Assure Smooth Operation of the Wireless Networks
Wireless alliances like Wi-Fi and ZigBee certify wireless devices for interoperability which to the end user provide a confidence level of smooth operation between these devices from different manufacturers. For instance this level of interoperability is necessary (but not sufficient) to ensure communications on WLAN Wi-Fi segments containing an Access Point (AP) and a number of wireless client cards. The same concept applies to ZigBee networks where interoperability gives a confidence level for ensuring operation of devices such as a light bulb and a switch, an RF4CE remote control and paired TV, DVD player or set top box, but also insufficient to assure seamless operation of the network over time and under variable environmental conditions especially in demand-response time critical scenarios.
