WiBro
Wireless Broadband, or WiBro, is based on the same standard as WiMAX, 802.16, but WiBro continues to work in motion and is therefore sometimes referred to as mobile WiMAX. WiBro is promoted as bringing mobile broadband access speeds to levels until now seen only on fixed-line networks.
WiBro-enabled cellphones allow always-on connections to the Internet, eliminating connection delays and permitting a service similar to that of a broadband fixed-line connection. Samsung developed WiBro in South Korea, where the commercial rollout is scheduled for the coming months, and the technology is now making inroads in the rest of the world.
Telecom Italia Mobile and Samsung tested Europe's first WiBro network in Turin during the Olympic Games in February. Telecom Italia Mobile has said it will begin selling WiBro phones at the beginning of next year, when it will make the WiBro service available. Source
