Following the WINNER vision of a ubiquitous radio system providing wireless access for a wide range of services and applications across all environments, D3.4 has continued the evolution of relay-based deployment concepts presented in D3.1 and D3.2 towards an understanding of the best deployment concepts for the envisioned WINNER scenarios. Continued work(More)
The deliverable is the first output of WINNER II Task 5 which is aiming to provide answers to the question on how relaying is implemented in the WINNER system concept, what performance can be expected by the relay based WINNER system concept and what gain in terms of cost can be expect from a relay-based solution in the different Concept Group (CG)(More)
An approach by the IST FUTURE project to make packet based multimedia services feasible in a satellite based UMTS environment. Different QoS guaranteeing mechanisms are presented exploiting the terrestrial UMTS specification in order to achieve an integrated T-S-UMTS. The focus is set on mechanisms for the access network, while the core network is only(More)
The huge growth in wireless communication has led to a wide range of technologies each addressing a particular scenario or need. The goal of the WINNER project is to develop a single new ubiquitous radio access system concept to address the whole spectrum of mobile communications scenarios. This paper surveys the challenge of providing ubiquitous operation(More)
Sporulation vs. competence provides a prototypic example of collective cell fate determination. The decision is performed by the action of three modules: 1) A stochastic competence switch whose transition probability is regulated by population density, population stress and cell stress. 2) A sporulation timer whose clock rate is regulated by cell stress and(More)
