    The growing demand for increased data rates and the surging volume of data traffic volumes have been behind the main push for the evolving 3GPP cellular standards. In order to meet those stringent network demands, the UE will need to evolve in the future to support the different 3GPP HSPA and LTE configurations required. Ultimately, 3GPP Rel-10 LTE-Advanced or True-4G enables peak data rates exceeding 1Gbps. This presentation will focus on reviewing some current 3G mobile platforms, then discussing key system challenges which the evolved UE configurations will impose on future cellular mobile platforms, and last but not least, some new RF architecture concepts going forward.

    Future Smart Grid systems will intelligently monitor and control energy flows in order to improve efficiency and reliability of power delivery. This monitoring and control requires low-delay, highly reliable communication between customers, local utilities and regional utilities. A vital part of future Smart Grids is two-way communication links between smart meters at the customer sites and a (decentralized) command and control center operated by the local utility.

    To enable two-way communication links, powerline communication (PLC) systems operating in the 3-500 kHz band are attractive because they can be deployed over existing outdoor power lines. Power lines, however, have traditionally been designed for one-directional power delivery and remain hostile environments for communication signal propagation.

    In this presentation, we review signal processing approaches to model channel impairments and impulsive noise and mitigate their effects in PLC systems in 3-500 kHz band. For impulsive noise, we show that the dominant component has a cyclostationary distribution, and that the secondary component follows a Gaussian mixture model. We examine ways to improve the communication performance based on current and emerging PLC standards.

    IEEE LCSC’12 is a competition among senior projects (graduation projects, capstone projects, or final year projects) from different universities in Lebanon on topics that have a communications component including wired and wireless communications, mobile apps, mobile networks, peer to peer and social networks, communications and network security, and related areas.

    Thirty teams from twelve universities across Lebanon competed on the basis of their final year projects that included a communications component. The teams were divided among three groups, based on their project theme: Mobile Applications and Mobile Devices; Systems, Devices and Hardware; and Algorithms, Simulations and Software. About a hundred people attended the event.

    IEEE LCSC'12 was successfully organized thanks to the platinum corporate support from Alfa, the first Lebanese mobile operator managed by Orascom Telecom, and silver corporate support from National Instruments Arabia, in addition to the collaboration of the Lebanese Association for Scientific Research (LASeR) and the AUB IEEE Student Branch.

    Intelligent Transportation Systems (ITS) have been attracting an increasing attention from car manufacturers as well as transportation authorities and communications standards organizations. ITS were identified as a key technology to promote increased safety, improve the national transportation infrastructure, and provide sophisticated information service to road users. Since numerous information (i.e. emergency messages, rich media content, infotainment data, etc) is exchanged between vehicles and roadside infrastructure, Vehicle to Vehicle Communications (V2V) and Vehicles to Infrastructure communications (V2I) become two important components of the ITS.

    Several wireless network technologies will pave the way to the communication system of the ITS. While IEEE 802.11p is the proposed standard for physical and MAC layer of V2V communications, High Speed Packet Access (HSPA), Long Term Evolution (LTE), and IEEE WiMAX /802.16e are advocated for V2I communications.

    However, due to the characteristics (high mobility) of the vehicle and several factors like quality of service requirements of real-time traffic, the provision of reliable data transmission and low-latency wireless communications is challenging for the network operator.

    In this tutorial, we will highlight wireless access standards in vehicular environment and discuss the quality of service methods and mobility protocols adopted in order to meet the road drivers’ expectation and increase road safety.
