Next-generation Cellular Technologies Combine Advanced Network
Topologies and Spectrally-Efficient Air Interface
Solutions for LTE-Advanced and Beyond
BARCELONA, Spain--(BUSINESS WIRE)--
InterDigital, Inc. (NASDAQ:IDCC) today announced the demonstration of
its "Fuzzy Cell" technology that improves cell-edge performance at the
2010 Mobile World Congress. The Fuzzy Cell technology is part of the
company'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.
"Many wireless operators and customers are experiencing a substantial
degradation of service quality caused by the ever-growing demand for
mobile data," said James J. Nolan, Executive Vice President, Research
and Development, InterDigital. "We are at the forefront of developing
solutions for more efficient wireless networks, a richer multimedia
experience, and new mobile broadband capabilities that support operators
to capture revenues from the boom in smartphones. The Fuzzy Cell fits
nicely within our much broader efforts on spectrum optimization,
cross-network connectivity and mobility, and intelligent data delivery
techniques."
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. It
is estimated that typical users experience this situation, known as
being in the cell-edge, more than 50% of the time. Advancements in HSPA
and LTE primarily increase peak data rates and only offer modest
improvements in average performance throughout a cell.
Fuzzy Cells is a novel approach for leveraging existing resources to
improve spectral efficiency and cell-edge performance. 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.
