Broadcast Radio Access Network (BRAN) is a project launched in 1997 by the European Telecommunications Standards Institute (ETSI) for a broadband wireless access area. The aim of the project is to develop new standards for broadband wireless access areas operating at transmission rates of 25 Mbit/s and higher in the microwave range between 3 GHz and 60 GHz. The BRAN concept relies on licenseable and license-free frequency ranges.
The "ETSI Project BRAN" is the successor of the Sub-Technical Committee RES10, which developed the specifications for Hiperlan. The ETSI BRAN specifications refer to the physical layer and the link layer in order to ensure the interworking of the broadband radio-based system with existing wireline systems based on ATM or TCP/IP protocols.IEEE 802.11, IETF, ITU-R.currently based on three wireless technologies: Hiperlan/2, a mobile broadband access network for the short range, Hiperaccess for wireless point-to-point connectivity in the access area, and Hiperman, a wireless access network operating below the 11 GHz range.
In addition, there is Hiperlink for fixed wireless connections with transmission rates of 155 Mbit/s.
