News & Analysis
WiMAX won't grab the brass ring as the technology that defines 4G cellular systems but it is likely to capture a healthy minority stake in that emerging sector and could help bring Internet access to a new-gen of consumer devices.
With the Unified Display Interface's demise, a new battle to crown a convergence digital display interconnect will play out over the next few years.
Developers for the consumer market should worry less about wowing users with gizmos and features, and more about how consumers actually use the devices.
At the IRRR Radio and Wireless Symposium held in January, academic researchers presented concrete examples of advanced wireless data and sensor networks.
Middleware specialists are exploring new ways to optimize existing architectures for SDR applications.
Bent on carrying out Moore's Law, Intel announced in January that it has scored another achievement in transistor design with the use of high-k and metal gate for the insulating walls and switching gates of its 45nm transistors.
