As a part of the EU-FP7 R&D programme, the OMEGA project (hOME Gigabit Access) aims at bridging the gap between mobile broadband terminals and the wired backbone network in homes. To provide Gb/s connectivity a combination of various technologies is considered. Beside radio frequencies, the wireless links will use infrared and visible light. Combined(More)
Gigabit home access networks (HANs) are a pivotal technology to be developed if the European Union (EU) Vision of the Future Internet is to be realised. Consumers will require such HANs to be simple to install, without any new wires, and easy enough to use so that information services running on the HAN will be ldquojust another utility,rdquo as, for(More)
A home network represents an increasingly large portion of a household's electrical consumption due to the increasing number of digital home devices and the increasing complexity of the underlying communication infrastructure. Limiting a home network's power consumption is a priority for large institutions as witnessed by evolving regulation, and a priority(More)
Optical wireless communication link (OWCL) requires a good transmission channel characterization. We present a physical method that uses a reduced-size model in order to characterize the impulse response of the optical wireless channel in real indoor environments filled with furniture. High resolution and real time characterization are the advantages of the(More)
project aims at bridging the gap between home and access network and providing Gb/s connectivity to users. The project considers a combination of various technologies such as radio-frequency and wireless optical links operating at infrared and visible wavelengths. When combined with power-line communications (PLC), this enables a home backbone that meets(More)
Digital home business is a large potential market for which ACEMIND European collaborative project intends to provide a set of consistent solutions to enhance the local network management in home and small enterprises. These networks are typically constituted by some tens of devices connected to each other via a set of wired and wireless technologies. The(More)
In this paper, the link budget of Gbps wireless infrared indoor communication is analysed. We particularly focus on the receiver sensitivity and identify the most suitable wavelengths range. We show that an optical receiver operating at 1 Gbps will hardly achieve the shot noise limit, which is determined by the received amount of background light. Regarding(More)
By Transmitting unipolar positive signals, a novel association of Alamouti space-time coding to free-space optic (FSO) communication is presented. We examine intensity modulation (IM) based on electrical fast Fourier transform (FFT) design with Hermitian symmetry. The proposed technique aims at limiting signal fading due to scintillation. It maximizes the(More)
