We compare 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 but also other subjects including range extension, low power and minimal 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 optimal candidate and development strategy.

Candidate Technologies

Cognitive Radio (CR)

Ultra-wide Band (UWB)

WiFi with MIMO

60GHz (Ultra High Frequency)
