Recently becoming the international 3G standard, WiBro gains ground again in the 4G market, as its 2.3㎓ frequency band is allocated for common 4G spectrum.
The World Radiocommunication Conference 2007 (WRC-07) held in Geneva, Switzerland selected 2.3㎓(2.3~2.4㎓, 100㎒) as a common spectrum band for the use of 4G service, announced the Ministry of Information and Communication of Korea. Accordingly, WiBro achieved the status of the international standard and the world common frequency band at one time.
According to ITU, 4G mobile communications, mostly multimedia data services, will require the minimum speed of 100Mbps on the move and 1Gbps for the standing device. The total bandwidth is likely to grow five times from current 330㎒ for 3G communications to 1,280~1,720㎒ by 2020.
Korea's information ministry expects the decision of WRC-07 after the ITU's approval of WiBro as the international 3G standard will enable WiBro service users to roam around the world, and thereby promote WiBro technology in the global market and boost the export of WiBro equipment.
