Talk outline:

The Challenge of Consumer Communications and Networking


Consumer networking presents a technological challenge - it is a tough distributed pervasive computing problem. Typical platforms for networked Consumer Electronics (CE) are resource-starved; users tend to be highly mobile; network access, if available, tends to be highly opportunistic. Users desire high degree of connectivity and desire communications with peers and access to content as well as sharing content and exchange services among each other any time, anywhere, by anybody. In this, consumers do not need to depend on service providers beyond opportunistic IP bearer service. Applications can be left to the market place and not managed by the infrastructure/service providers. We present consumer-desired application scenarios and devise an approach to realization of a true Peer-to-Peer consumer-networking paradigm. We illustrate deployment scenarios of Peer-to-Peer Multimedia applications, based on P2P protocols. Critical enabling mechanisms like session control, presence and location management, security and others are based on P2P principles; employ P2P SIP and its extensions.

 Highlights of ComSoc Technical Activities–Supporting Competitive Research

 For the past several years our industry exhibited shortened “time-to-market” cycles for new technologies. Often applied research is conducted simultaneously with development and in synchronism with standardization. “Just in time inventions” became a way of life. In order to operate in this environment ComSoc must evolve from a strictly scholarly group catering mostly to pre-competitive research into a “full service” society that facilitates all stages of the technology value chain: from basic research to standards. Dr. Gelman will present ComSoc current standards portfolio and the methodology by which we can impalement standardization projects and facilitate relevant to standards research

February 8th, 2007: "Using Ultra Wideband for Whole Home distribution of digital content over wireless and wired media"
By: John Santhoff, Pulse~Link Founder and Chief Technology Officer



 Talk outline:

The talk will be divided in two halves. During the fist half of the talk, John Santhoff will focus on Ultra Wideband (UWB) applications and 802.15.3.

During the second half, John Santhoff will talk about the technical details of Pulse~LINK design philosophy and requirements when they designed their chipset.

The use of UWB technology opens new applications for UWB over both wireless and wired communications channels. By using a hybrid network consisting of both wireless and wired medias, this technology is able to extend and expand the delivery of HDTV, multi-channel Audio and High Data Rate digital data seamlessly throughout the home. At short-range, it achieves Gigabit data rates enabling unprecedented connectivity of "video-centric" technologies such as wireless 1394b and HDMI/DVI. Pulse~LINK is a pioneer on implementing this technology.

During the presentation John Santhoff will discuss briefly on the Pulse~Link C-Wave platform and how they have been able to utilize multi-Giga sample DAC's and ADC's thus reducing physical layers to software abstractions for both wired and wireless communications. Their chipset solution is the first step towards a Software Defined Cognitive Radio (SDCR) architecture, seamlessly bridging and integrating one platform for both wired and wireless devices to communicate throughout the home.

We are privileged to have a distinguished speaker like Dr. Louay Jalloul give us a talk on IEEE 802.16e (WIMAX)..



 Talk outline:


The past decade has witnessed an unprecedented growth in the use of wireless communications. While most of the current usage has focused on voice, high speed data seems to be the driving force behind the recent development of the wireless communications standards. We now see an emergence of a nation wide deployment in the United States of 1X-EV-DO, Europe’s 3GPP/wideband CDMA (HSDPA, HSUPA, and the long-term evolution) as well as the IEEE 802.16e standard which was completed at the end of 2005.


In this talk we focus on the WiMAX profile (which is a subset of the features standardized under 802.16e). Several key features in WiMAX system are addressed in this talk, namely orthogonal frequency division multiplexing (OFDM), adaptive modulation and coding, multi-user scheduling, and the use of multiple-input multiple output antenna (MIMO) systems. We follow a systems approach in evaluating the performance of a WiMAX system in a single frequency reuse multi-cell network deployment. System performance is described in terms of spectral efficiency, sector throughput, user throughput, range and coverage.





Louay M.A. Jalloul has been a senior director of technology at Beceem Communications Inc. (Santa Clara, California, a leading Silicon Valley start-up offering semiconductor solutions for the broadband wireless communications market) since September 2005.

We have been privileged to have a distinguished speaker like Prof. Nitin H. Vaidya give us a talk in the exciting field of multi-channel wireless networks.



 Talk outline:


Wireless technologies, such as IEEE 802.11a, provide for multiple non-overlapping channels. Typical multi-hop wireless network configurations have only used a single channel for the network. The available network capacity can be increased by using multiple channels. However, the number of interfaces per node is expected to remain smaller than the number of channels, and therefore a single node cannot simultaneously use all the channels.


In this talk, we present the capacity of general multi-channel networks wherein the number of interfaces per node may be smaller than the number of channel. Under this scenario, we show that for a random network of n nodes, there is no capacity degradation even with only one interface per node, as long as the number of channels is less than O(log n).


Thus, in theory, multiple channels can improve network capacity significantly even with a small number of interfaces per node. However, in practice, many challenges have to be addressed before the capacity improvement can be realized. We present practical protocols for utilizing multiple channels that address many of these challenges. One set of protocols has been designed for the scenario where each node may have only one interface. Another set of protocols has been designed for the scenario where each node has multiple interfaces. We will present results from simulations that demonstrate the effectiveness of our proposed protocols in significantly increasing network capacity. The talk will also discuss our work on implementing selected protocols on a wireless testbed.


This talk is based on joint research with graduate students Pradeep Kyasanur and Jungmin So.
