OMEGA

10-12 May 2010 | Barcelona, Spain

SCOPE:

The aim of FP7 OMEGA project is to integrate various appropriate technologies into a converged heterogeneous network, improving the quality of service, reliability and throughput. Gigabit radio frequency and optical links, combined with more robust local area radio frequency and visible light communications (VLC) will provide wireless connectivity within the home and its surroundings. The combination with power line communication (PLC) backbone will lead to a home network “without new wires.” From user perspective the goal is to provide ubiquitous and self-configurable networks, with simple installation and management. In order to realize this vision, substantial progress is required in the fields of optical wireless and RF physical layers, in protocol design, and in systems architectures.

In this session, technical presentations of advancements with respect to wireless technologies, seamless access and seamless convergence for home networks will be given. The focus will be on radio communications and wireless optics. For Gbps radio in-home networks, the considered radio technologies comprise state-of-the-art systems like WLAN IEEE 802.11n, emerging systems based on WPAN UWB (WiMedia) and systems at development stage like WPAN 60 GHz (IEEE 802.15.3c, IEEE 802.11ad, ECMA-387, WirelessHD, WiGig). The special session covers the necessary adaptations and enhancements of the PHY and MAC layers to provide Gbps for future ultra-high rate applications. Improving the coexistence and cooperation between the different systems is a necessity for reliable communication within the home network. Convergence at the radio layer will consequently be a main topic of the special session. Further important topics include cross-layer algorithms to make efficient coexistence possible and achieve the required performance, cooperation to realize interference mitigation, self-organization to avoid any user effort, multi-user MIMO, link adaptation, advanced power management, distributed scheduling and efficient spectrum sharing.

Regarding the optical wireless part of the special session, physical layer approaches for infrared (IR) transmission and visible light communication (VLC) are presented. IR hotspots will provide high speed (Gbps) line-of-sight links. VLC will be used to broadcast data at bit rates of 100 Mbps by using the interior LED based lighting. Since the modulation bandwidth of these LEDs (which provide the illumination as well) is limited to about 20 MHz, advanced techniques such as discrete multitone modulation are required to mitigate dispersion effects. One presentation discusses an alternative approach which is based on single-carrier block transmission with frequency domain equalization. Since optical transmission relies on intensity modulation and direct detection, major differences compared to similar RF approaches will occur. A major challenge regarding wireless IR transmission is the link budget. The OMEGA approach favours transceivers which split the wide angular range to be covered into several sub-sectors. Assuming line-of-sight, this ensures not only a transmit and a receive gain − it enables also space division multiple access. With respect to IR transmission, the choice of the wavelength will also be discussed where it can be concluded that the near IR range (about 750-850 nm) is still a good choice for data rates of up to 1 Gbps. However, data rates well beyond 1 Gbps demand a wavelength range between 1300 and 1550 nm.
