In this paper the cellular aspects of a concept will be investigated that introduces a new element called forwarding mobile terminal (FMT) to the HiperLAN/2 (H/2) world. The FMT is designed to extend the area of an H/2 access point and provide users in uncovered areas with access to the fixed Internet by providing an intermediate hop. The FMT is a modified(More)
The BMBF founded project COVERAGE investigates broadband access to the IP core-net in public or semipublic hot spot scenarios for mobile users. The basis for our investigations are OFDM-systems (Orthogonal Frequency Division Multiplex) like H/2 (HiperLAN/2) or IEEE802.11a which provide data-rates up to 54 Mbit/s. Main topic of COVERAGE are multihop networks(More)
Abstract: In this paper a concept will be presented that introduces a new element called forwarding mobile terminal (FMT) to the HiperLAN/2 (H/2) world. The FMT is designed to provide users in uncovered areas with access to the fixed Internet by providing an intermediate hop. The FMT is introduced in a way that it is backward compatible to existing H/2(More)
This work presents a concept and the related analysis of the traffic performance for a wireless broadband system based on fixed relay stations acting as wireless bridges. The analysis focuses on the important performance indicators end-to-end throughput and delay, taking into account the effects of an automated repeat request protocol. An extension to a MAC(More)
This paper provides a comprehensive overview of the development of performance critical communication systems such as HiperLAN/2(H/2), the corresponding timing concepts for H/2 Mobile Terminal (MT) and Access Point (AP) protocols and the protocol implementation in a hard real time system. Moreover, the paper introduces some concepts to optimize the(More)
