This page compares the candidate technologies for advanced wireless communications for multi-giga bits transmission. In the future wireless devices are expected to require basically ultra high rate (UHR) for ultra high definition video delivery as well as other subjects including range extension, low power processing and seamless mobility adaptation. The following state-of-art technologies can satisfy some conditions but not all for future wireless networks. Therefore, we compare the advantages or disadvantages to choose the optimal candidate and development strategy.

Cognitive Radio (CR)[]
Cognitive radio provides a method to sense a signal in the primary user band and allows for secondary use to use that band if it is not used for a moment.
