Events
InterMAC demonstrator
The demonstrator will show Omega InterMAC usage based on FPGA based hardware, simulating a meshed network containing:
- an Omega Gateway, injecting web data and video content into the Omega network
- some Omega devices, like the ones connected directly to the FPGA boards, ready then for Omega QoS / QoE information display
- some non-Omega devices (legacy devices), connected to FPGA boards through regular Ethernet, demonstrating the scalability of Omega network
- mobile Omega devices for simulating the handover feature. The demonstrator will be completed with extra schematics for highlighting the advantages of InterMAC.
VLC demonstrator
OMEGA will demonstrate a novel technology that is expected to constitute a building block of future high-speed home-area networks: visible-light communication (VLC). The salient idea behind this technology is to rapidly modulate the illuminance of light emitted by, e.g., ceiling lamps. Hereby, the modulation frequency is chosen so high that the naked eye cannot resolve the light variation.
In our final demonstrator (November 2010), 16 white LED spot lights will be integrated in the ceiling of the showroom at Orange Labs in Rennes. Besides illuminating an area of about 10 m2, the lamps will also broadcast data at 100 Mbit/s. For the showcase at this Open Event, data will be transmitted and modulated by a receiver on a desk. The data rate demonstrated is high enough for the parallel transmission of several high-definition video streams.
Optical wireless system demonstrator (video)
In this video demonstration we will present the operation of a 1.25Gbit/s line of sight indoor optical wireless system. This is the fastest system of its type, and transmits bi-directional Gigabit Ethernet traffic over a range of 3m or so. The system is based on angular diversity transmission and reception and switches between three bi-directional channels according to the alignment of the two terminals. In this demonstration we will show the major features of the system, transmission of data traffic, and discuss future directions for this work.
UWB Multi-Gigabit Wireless Software platform (video)
This software demonstration is based on a film using signal captures issued from link level simulations and advanced software platform to illustrate Multi-Gigabit receiver and transmitter signal waveforms passing through a software channel simulator. The demonstration shows performance of optimized Multi-Gigabit Wireless Systems (MGWS) operating at 60 GHz and in UWB bands and exhibits real time constellation points and associated sliding averages of BER. The PHY layer system combines Turbo FEC with Turbo Interleaving techniques to increase performance and radio coverage. The system encompasses multiple UWB interfaces considering ECMA-368, an optimized Multi-Band UWB Multi-Carrier PHY layer system and modified IEEE802.15. H.S.I modes implementing Turbo-Codes. A novel algorithm intended to dynamically select WPAN air interfaces is presented and applied to UWB and WB WPAN systems operating at 5 GHz, in UWB spectrum mask {3.1-10.6} and in {57-66} GHz bands. This algorithm involves a novel layer 1 metric intended to be integrated into the OMEGA Inter-MAC management process.
