WiMAX - WiBro-wireless broadband internet - WiMax

WiBro is better than WiMAX?

The cumbersome and time-consuming negotiations and tests for the WiMAX technology could possibly be the alternative technique to an unexpected WiBro give up. That at least is speculation from the market researcher ABI Research indicates. During the WiMAX Forum is still with compatibility problems and the possible introduction of the IEEE 802.16e substandard employed, the Korean founder of the once dismissed WiBro technology even further: WiBro is already in a position to data on fast-moving equipment to pass. In tests succeeded a broadband connection to a mobile device that is 60 km / h and moving between two base stations to pass.

In Asia, demand for mobile technology is particularly high. Therefore, preparation are already in, two telecommunications companies in South Korea on the large-scale are launching WiBro wireless networks. Sections commend at the beginning of the year 2006. Even Japanese government is the very open and interested in Mobile technology

International Worldwide Interoperability for Microwave Access.

Forum (WiMAX) had official tests of the WiMAX standard IEEE 802.16-2004 for the month of October 2005. WiMAX, which stands for Worldwide Interoperability for Microwave Access. There is a new standard (IEEE 802.16e) for regional radio networks. With theoretically up to 50 km range and a data transfer rate of up to 109 Mbps (at 28 MHz bandwidth) than WiMAX the current WLAN technology, the outdoor use on-3-6 km range. WiMAX wireless LANs can transit voice data, for example voice over Ip protocol (VoIP). This is a special Quality of Service (QoS) mode planned. The WiMAX technology enables broadband connections in those regions were DSL services can not provided.

WiBro is a Korean standard. These Wimax variant is mainly the broadband data with onboard devices support. According to the company's Samsung WiBro allows Handovers for up to 120 km / h and thus as an alternative to mobile technologies of third generation (3G) UMTS as relevant.

For development outfitters WiBro and the Korean Electronics and Telecommunications Research Institute (ETRI)are working together. It had the Korean government in 2002, a frequency band of 100 MHz in the 2.3GHz spectrum for WiBro was released. In June 2004 the standard Phase 1 of WiBro allows a data throughput from 20 to 30 Mbps in cells whose radii of one to five kilometers amount.
