Spectrally Efficient Air Interface Solutions for LTE-Advanced and
Beyond
KING OF PRUSSIA, Pa.--(BUSINESS WIRE)--
InterDigital, Inc. (NASDAQ: IDCC) today announced that the company will
present at the LTE World Summit 2010 to be held in Amsterdam,
Netherlands on May 18-20, 2010. Dr. Ariela Zeira, InterDigital’s
Vice-President of Advanced Air Interfaces, will provide an overview of
the company’s cellular technology roadmap and elaborate on advancements
in “Fuzzy Cell” technology that address inconsistent and non-uniform
performance across the cell. The Fuzzy Cell technology is part of
InterDigital’s comprehensive suite of “Next Generation Cellular” (NGC)
innovations that combine advanced network topologies and
spectrally-efficient air interface solutions for LTE-Advanced and
beyond. LTE (Long Term Evolution) technologies are under development
globally to support the next generation of cellular air interface
technology.
Building on the company’s legacy of inventing fundamental technologies
used in 2G, 3G, and LTE cellular systems, InterDigital is now developing
a new comprehensive set of advanced solutions that will drive future
wireless systems, including LTE-Advanced. Using a holistic approach to
solving network congestion, InterDigital is focused on three
comprehensive areas of bandwidth innovations: spectrum optimization;
cross-network connectivity and mobility; and intelligent data delivery
techniques, using the descriptive phrase “bigger pipes, more pipes, and
better pipes.”
“The wireless industry is facing one of its biggest challenges ever in
terms of providing mobile users with the necessary bandwidth to drive
all the applications people need and want on the go,” said William J.
Merritt, President and Chief Executive Officer of InterDigital. “Our
ambitious effort on Next Generation Cellular directly addresses this
impending bandwidth crunch and fits perfectly with InterDigital’s
reputation for solving the industry’s toughest technical problems.”
During her presentation at the LTE World conference, Dr. Zeira will
focus on the company’s roadmap for “bigger pipes” and elaborate on the
novel Fuzzy Cell approach for leveraging existing resources to improve
spectral efficiency and cell-edge performance. While cellular networks
have become virtually ubiquitous, users continue to experience
inconsistent and unpredictable performance when moving around. While
this degradation is often the result of network congestion or an
obstructed path of the radio waves, it is also inherent to traditional
cellular deployments, whereby signals degrade towards the fringe of any
given cell due to interference from neighboring cells. Typical users
experience a degradation of signal throughput, known as being at the
cell-edge, the majority of the time. Because of this, advancements in
HSPA and LTE, which primarily increase peak data rates at the center of
the cell, only offer modest improvements in average performance
throughout a cell.
In a traditional deployment, a device connects to one site at a time
(even if multiple sub-bands are used at each site) and all sites use the
same power levels and sector orientations for all sub-bands. In a Fuzzy
Cell deployment, a device may connect to multiple sites at a time
through the different sub-bands and continue to realize full system
bandwidth. The power levels and sector orientations of the different
sub-bands are optimized for best performance. In simpler terms, the
device exploits the best combination of base station support regardless
of its position, removing traditional limitations of cell or sector
boundaries. Importantly, Fuzzy Cell technology can also allow gains
indoors as it allows connection to more than one cell/sector at a time
as available. The Fuzzy Cell technology provides additional improvement
over Fractional Frequency Reuse (FFR) methods that are supported by
current specifications.
