Welcome to the IEEE San Francisco site. Please take
a look at the different tools and links that bring the exiciting world
of the Internet and Network Engineering to you. In addition we have
a large number of past speakers of our events and their biography
information listed below. Thanks for coming and enjoy the show.
IEEE San Francisco Communications Society and the Distinguished Lecture
– Future Radio Access LTE is rapidly emerging as the dominating 4G standard
throughout the worlds, taking mobile broadband to unprecedented performance
levels. The latest version of the LTE standard, known as Rel-10 or LTE-Advanced,
by a wide margin fulfills the IMT-Advanced requirements and is one of two technologies
approved by ITU as IMT-Advanced compliant. Currently, 3GPP is focusing on Rel-11,
taking LTE further beyond the IMT-Advanced requirements.
The talk will provide an overview of the main technology components of LTE-Advanced – enhanced
multi-antenna transmission, relaying and carrier aggregation – as well
as components such as CoMP and dynamic TDD considered for future LTE releases.
In addition to these techniques, meeting future demands for even higher data
rates requires a denser infrastructure, for example in the form of a heterogeneous
deployment where low-power nodes complement the basic coverage provided by
a macro cell.
Such deployments are expected to become increasingly important in the future
and may call for enhancements in e.g. inter-cell interference management,
as well as further stress the importance of energy efficiency given the large
number of nodes. The increasing usage of machine-type communications, where
the challenge often is the enormous amount of devices connected rather than
the data rates themselves, is another focus area for future radio access.
The presentation will discuss these challenges, as well as others, and some
technologies for addressing them.
Stefan Parkvall is currently a principal researcher at Ericsson
Research, working with research on future radio access. He is actively participating
in 3GPP physical-layer standardization and is one of the key persons in the
development of HSPA, LTE and LTE-Advanced radio access. Dr Parkvall is a
senior member of the IEEE and co-author of the popular books “3G Evolution – HSPA
and LTE for Mobile Broadband” and “4G – LTE/LTE-Advanced
for Mobile Broadband”.
In 2009, he was co-recipient of the prestigious “Stora Teknikpriset” (Sweden’s
major technology prize) for his work on HSPA. He received the Ph.D. degree
in electrical engineering from the Royal Institute of Technology in 1996.
His previous positions include assistant professor in communication theory
at the Royal Institute of Technology, Stockholm, Sweden, and a visiting researcher
at University of California, San Diego, USA.
The Public Utilities Commission is on the corner of Van Ness and McAllister
diagonally across from City Hall. There is a parking lot on Franklin
between McAllister and Golden Gate and underground lots at Opera Plaza
on Golden Gate between Franklin and Van Ness and at Civic Center Plaza
on McAllister between Polk and Larkin. Parking under the PUC is not
open to the public. Parking meters west of Van Ness are inactive after
6:00 PM. Any bus running on VanNess will stop on the corner.
Coming from the East by BART or Metro,
it is best to transfer to a No. 5 Bus going west at the Powel Street
Station. Alternatively, it is a 5 to 10-minute walk from Civic Center
Station and about the same from Van Ness Station.
Coming from the West by Metro or bus, transfer
to a bus going North on Van Ness.
There are two entrances to the building. One is under the state
seal at the top of the steps on the corner of Van Ness and McAllister.
The other is on Golden Gate between Franklin and Van Ness. The
gates for both entrances close at 5:30 pm. It is better to use the Golden
Gate entrance because the meeting room is just inside.
