This work is carried out within the OMEGA project [1] where multiple transmission interfaces are intended to cooperate together. Multipath signature and link budget are investigated to carry out first assessment of the proposed WPAN hybrid system. Results are in favour to 60 GHz but advanced baseband processing for WO should provide similar performance as 60 GHz

This metric, denoted Green Link Budget (GLB) metric resorts from link budget assessments upon realistic and idealistic cases. Several architectures are proposed for set-up issues at the PHY/MAC and inter-MAC layers.This metric is promoted though different collaborative projects such as the ICT-FP7 METIS project and the ICT-FP7 Europe/Japan MiWEBA project.

The algorithm utilizes modulo operations and a turbo-based structure to optimize the frequency interleaving spreading over multipath channels. The algorithm undertakes a dynamic set-up (denoted Dynamic Interleaving Code, DIC) to fictively introduce a time-frequency diversity of the channel on the system. TheDIC provides gains up to 3 dB

While radio spectrum above 6 GHz offers contiguous high bandwidth resources for high capacity radio links; it gives rise to new challenges in terms of user mobility and reliability due to the harshness of the mobile radio environment, necessitating the deployment of highly directional links. To overcome these challenges, we propose architectural solutions based on tight integration of mm-wave RAT with RAT(s) operating in frequencies below 6 GHz with the intention to diversify the control plane and data split, and the duplication of the user plane. The paper outlines initial architectural concepts envisioned for 5G mm-wave systems designed to operate in frequencies between 6-100 GHz, and discuss some crucial aspects of its integration within the 5G networks. The proposed concepts include: i) network slicing to addres...

We have achieved very stable operation of the electron beam at 10 A through the EBIS trap. Ion injection of low charge gold ions from a LEVA [1] ion source and subsequent extraction of these ions with most probable charge state AU34+has been demonstrated with electron beams up to 8A. The total ion charge for gold measured on current transformer at the EBIS exit was 55nC after a 3Oms confinement period. This corresponds to-85°/0 of the theoretical ion trap capacity and exceeds our goal of 50'?40 neutralization. The collected ion charge is proportional to the electron current and the gold charge state scales with the electron current density. Details of the EBIS coni-lguration, total charge measurements, and TOF spectra are given

Multiple radio access techniques are one of the most promising paradigm safeguarding throughput increase and seamless connectivity in heterogeneous networks. Link adaptation metrics are then required to achieve radio link selection and multiple interface management. Following mobile network capacity increase trends, link adaptation metrics focused on spectrum efficiency maximization are implicitly sought, involving high network power consumption. This paper presents a novel link adaptation metric turned toward a power efficient radio link selection which warrants QoS and performs a fair comparison between independent air interfaces in a multiple radio access technique context. A procedure is proposed to practically evaluate the metric upon each air interface, thanks to the introducion of new normalized propagation selectivity parameters with respect to system parameters allowing a unified characterization of the propagation link reliability, tuning up the metric decision. Performance and transmit power gains resulting from the metric application are appraised upon wireless hot spot extensions covering 5GHz and 60GHz Wi-Fi technologies and mm-wave ultra-wide-band transmissions.

For Fixed HS (FHS), Time Reversal (TR) and Equal Gain Transmission (EGT) techniques are recommended and optimized under Multiple Input Single Output (MISO) deployments within the context of Wi-Fi HS extensions operating at 60 GHz. For Mobile HS (MHS) scenarios, adaptive and switching beamforming (BF) techniques are investigated and evaluated to track HS combining Long Term Evolution-Advanced (LTE-A) and mmWave transmissions using the IEEE802.11ad and IEEE802.15.3c standards. Link budget are performed for those scenarios, proving feasibility of mmWave and Wi-Fi backhauling for future fifth generation (5G) networks.
