The Challenge of Consumer Communications
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
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
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
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)..
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. Prior to Beceem, he was an associate professor at

multi-channel wireless networks.
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
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.
