Today it competes directly with WiMAX Technology, But some specialists minimize incompatibilities, The WiMAX Technology is still growing, and different techniques deviant a day coexist.
The WiBro (Wireless Broadband) provides eventually flow down between 1 and 3 Mbps and between 128 and 512 Kbps for upstream. The response time is around 150 milliseconds.
The Ministry of Information and Communications Korean published in late July 2004, the national technology WiBro (Wireless Broadband) and appointed in late August 2004, operators who can take the adequate radio spectrum. Korea Telecom (KT) to deploy broadband band wireless in Korea last year.

In late August, an appeal was launched by the government from operators. Three of them replied, SK Telecom, Hanaro Telecom and LG Telecom. In January 2005, the three operators have obtained license rights against some 86 million euros. This year, laptops bimodes WiBro-3G should appear on the market, followed in 2006 by various services.
