| Developed in South Korea, WiBro (Wireless Broadband) is the newest
variety of mobile wireless broadband access. WiBro is based on the same
IEEE 802.16 standard as WiMax, but is designed to maintain connectivity
on the go, tracking a receiver at speeds of up to 37 miles per hour (60
km/h). WiMax is the current standard in the United States, offering
wireless Internet connectivity to mobile users at fixed ranges of up to
31 miles (50 km) from the transmitting base. However, WiMax is not
designed to be used while the receiver is in motion. WiBro can be
thought of "mobile WiMax," though the technology and its exact
specifications will change as it undergoes refinements throughout its
preliminary stages.
Korean-based fixed-line-operators KT, SK Telecom and Hanaro Telecom
were awarded licenses by the South Korean government to provide WiBro
commercially. According to Asia Media News Daily, the Korean Times
reported a glitch in the initial excitement of WiBro, as published 31
August 2005. Hanaro Telecom gave up its license for WiBro after
concerns that the considerable investment required would not see a
return, while SK Telecom was also said to be hanging back. Only KT
remained enthusiastically committed in the push to make WiBro a
reality. Meanwhile Samsung has shown great interest in providing
devices with WiBro capability.
WiBro is expected to be widely deployed in South Korea by the middle
of 2006. As it may become the 4G (4th Generation) wireless standard,
the global market will be watching. WiBro will operate in the 2.3
gigahertz band and is interoperable with WiMax.
South Korea is one of the most connected nations in the world.
Broadband Internet access is widespread via DSL, cable and WiFi. South
Korea also led the world market in quickly commercializing 3G (3rd
Generation) cellular services like CDMA2000, a faster version of the
Code Division Multiple Access network. Like the United States, South
Korea is one of the few nations to use the cellular CDMA network more
prominently than the more widespread GSM (Global System for Mobile
communications). With its great enthusiasm for wireless technology,
Korea promises to provide a solid testing ground for WiBro.
