Is Super Wi-Fi a subset
of Wi-Fi? Will White Spaces mobile devices become a reality in 2011?

‘5G’ Technology
Key concepts discussing 5G wireless communications are:
Networks providing ubiquitous computing: User can simultaneously be connected to
several wireless access technologies and seamlessly move between them.
802.21 - Standard supports algorithms enabling seamless handover between
networks of the same type as well as handover between different network types also
called Media independent handover (MIH) or vertical handover.
