overview how it works future applications for researchers

Obtaining better speed faster connections, faster delivery of information is a driving force behind wireless communication technology. Manufacturers are beginning to reach the physical limits of what they can do with ordinary silicon-based materials, which are the traditional building blocks for most consumer and business wireless products, such as cellular phones, wireless Local Area Networks, and direct-to-home satellite services.However, a new semiconductor technology from IBM provides a significant breakthrough, allowing silicon technologies extension into wireless technology.
