4G wireless technology: When will it happen? What does it offer?

Fourth generation (4G) technology will offer many advancements to the wireless market, including downlink data rates well over 100 megabits per second (Mbps), low latency, very efficient spectrum use and low-cost implementations. With impressive network capabilities, 4G enhancements promise to bring the wireless experience to an entirely new level with impressive user applications, such as sophisticated graphical user interfaces, high-end gaming, high-definition video and high-performance imaging. This paper will explore what 4G technology is, as well as some of the key factors that must be addressed to fully comprehend the benefits and challenges of successfully implementing 4G. Silicon level technology issues will be addressed, such as next-generation applications processing, modem technology, power management and integration. Finally, the trends and predictions for 4G network deployment will be discussed.
