Concepts for IP-based radio interface in the BRAIN framework

Considering that mobile communications systems and the Internet are key technologies for the development of the information society, one objective of the European IST project BRAIN is the design of a mobile broadband IP radio interface. This radio interface is based on the ETSI HIPERLAN Type 2 standard with some enhancements necessary to optimise the system for the delivery of IP broadband services with high QoS and mobility requirements. The project is working on optimising layer 2 algorithms and protocols for IP mobile services such as adapted schedulers, optimised handover procedures, handling of a standby mode and specifying a dedicated LP Convergence Layer able to transport efficiently IP version 4 as well as version 6 packets over the air and interworking with LP mobility and QoS functions.
