Abstract:
Wireless access architectures employing femto- and pico-cell base-station/access point can reduce power consumption and enhancing wireless spectrum utilization by shortening the links and exploiting cooperative and cognitive mechanisms, but co-ordinations between base-stations or access points may incur large overheads. We present a novel architecture that exploit wireless-optical convergence for next generation broadband wireless access employing fibre-connected massively distributed antennas (BWA-FMDA). In this architecture, a large number of distributed antennas are connected via radio over fibres (RoF) to a centralized processing entity to minimize the communication overhead of system co-ordination. The coverage area of the proposed BWA-FMDA system can range from a few tens of square meters in homes and office environments, delivered via IEEE 802.11a/g/n or femto-cell hotspot solutions, to several square kilometers supporting last-mile technologies such as WiMAX, LTE, and LTE-A using pico- and micro-base-stations. This new architecture leads to many new research problems, including the fundamental performance limits of massively distributed antenna systems, improved measurement-based channel models involving massively distributed antennas, advanced radio resource management and access control schemes that approach the performance limits in realistic propagation environments, and improved opto-electronic transceivers designs for low cost active optical cables suitable for RoF applications. In this talk we demonstrate the potentials of BWA-FMDA architecture by considering its application in license-free and licensed wireless systems. We present the cognitive WLAN over fibre (CWLANoF) system, which applies the BWA-FDMA architecture in the license-free ISM band for cooperative spectrum sensing, interference avoidance/mitigation and dynamic channel assignment. BWA-FMDA can also be applied in licensed bands to create coordinated multiple point (CoMP) operations of femto-cells, which provides higher spectral efficiency (bps/Hz) and higher energy efficiency (bits/Joule). Simulation results and address potential research issues are presented for each scenario. We conclude with a short discussion on our current effort to develop and deploy a BWA-FMDA testbed based on commercially available equipment.

Abstract
Spurious emissions of wireless devices, intentional radiators, deteriorate the equipment performance and interfere with other services and equipment. In this presentation, the broad impact of high frequency spurious emissions from wireless devices on low power and high power equipment are discussed first. After a brief review of the regulatory requirements on spurious emissions of licensed wireless equipment, how to measure both the conducted and radiated spurious emissions is addressed. Finally the suppression techniques of spurious emissions are presented.

Title:
Evolution of IP Multimedia Subsystem (IMS)

Abstract:
Commoditization of voice service has reached such a state that anyone with a server to provide registry and addressing (identification) functions can offer it to the Internet community using the voice over the Internet protocol (IP) or VoIP technology. Traditional client-server model has evolved to peer-to-peer and cloud models for near-real-time voice and multimedia (gaming, video, etc.) sessions.

Voice mail service is being replaced by Instant messaging (for presence-announced users), use of Star codes for advanced call/session feature activation is being replaced by Web based service-provisioning interface, and so on. Similar revolution is also happening in the areas of IP-based Television (IPTV) service development and distribution.

These are only a glimpse of what is possible with the new/emerging converged services paradigm. However, many issues related to reliability/availability, security/privacy, mobility, service provisioning and continuity, regulation, operations, and quality of service and experience (QoS/QoE) still remain open.
In this discussion, we will explore the current activities of the traditional service providers to find implementable and operable solutions to these problems in the evolving Next Generation Networks (NGNs). The objective is to support VoIP, IPTV, and other multimedia services /seamlessly /over a variety of interconnected networks using the emerging IP multimedia subsystem (IMS) and service-oriented architecture/network (SOA/SON) based standards.

Bio:
Dr. Bhumip Khasnabish is a Distinguished Lecturer of the IEEE Communications Society. He has authored numerous patents and publications in a variety of areas related to converged services and new generation networking. He recently authored a Book Chapter (Chapter 4) entitled "Next Generation Technologies, Networks, and Services," for publication in "Next Generation Telecommunications Networks, Services, and Management," Edited by T.

Please mark your calendars for this special event.

If you are tired of designing your software with a whiteboard, but you hate UML, then textual modeling might be for you. Ever wanted to 'just write some code' but didn't want to actually build the whole product? Just need a prototype, but want it to actually be stable? Then 'M' might be for you. Bill will eschew the slides, fire up ye old text editor and design a piece of software from his upcoming Wrox book on textual modeling. You will learn what 'M' is, what it isn't, and how it is going to help you design better software.

This special event is with Bill Sempf a well-known author of several programming books.
