Wireless Broadband (WiBro) is an alternative to WiMAX. It was developed in South Korea and even there by the Telecommunications Technology Association (TTA) of Korea standardized. As WiBro mobile the same approach as IEEE 802.16 persecuted and had a development advantage, the IEEE committee the WiBro project into the development process for 802.16e. This flowed certain developments in the mobile WiMax, particularly the transmission SOFDMA.
In 802.16e is a radio service for broadband, mobile access is defined, more or less for the mobile, wireless Internet.
Specifications of WiBro
WiBro supports with data rates between 20 Mbps and 50 Mbps It is distinguished by the handover and may, at speeds exceeding 100 kph received. The WiBro wireless cells have a radius of one to five kilometers. As the transmission frequencies using the Koreans and Japanese, a 100-MHz band at 2.3 GHz. Technically WiBro transmission works with scalable SOFDMA with 2,048 subcarrier.
WiBro offers service (QoS), making it even for streaming media and VoIP is interesting. In conjunction with the handover, it can also as an alternative to the techniques of the 3rd mobile Generation (3G) such as UMTS will be considered.
In order for the wireless broadband technologies, WiBro and WiMAX later mutually compatible, have well-known chip manufacturer and Korean firms, the WiBro project have developed for compatibility issues asserted
