IHS INC. 
By IHS has identified a radio frequency microelectromechanical system (RF MEMS) device in a new Samsung cellphone, marking the first known use of such a part in a volume-shipping product-and sounding the starting gun for an RF MEMS market that is set to grow by a factor of 200 by the year 2015.
Samsung's Focus Flash Windows smartphone includes an RF MEMS device from WiSpry Inc., according to the at information and analysis provider IHS (NYSE: IHS).
RF MEMS devices like the WiSpry part can provide a range of benefits in cellphones, including the reduction of signal interruptions and dropped calls, faster data transmission rates and improved design and power efficiency. The Focus Flash has been shipping in the United States since November, 2011. This will pave the way for other cellphones to adopt RF MEMS, causing global sales of such devices to rise to $150 million in 2015, up from just $720,000 in 2011, as presented in the figure attached.
"RF MEMS have been promoted by suppliers as the next big thing in cellphones for nearly a decade," noted Jérémie Bouchaud, senior principal analyst. MEMS and sensors for IHS. "However, although they have been shipping since 2005 in low volume for instrumentation applications, interest among cellphone makers in the use of RF MEMS didn't pick up until mid-2010, when users began to report problems with signal reception with the iPhone 4 after they held the device in certain ways. This so-called "death grip" problem can be alleviated through the use RF MEMS. When combined with the other benefits delivered by RF MEMS, the market for these parts is set for rapid growth in the coming years."
