InterDigital's Fuzzy Cell Technology a Hit at Mobile World Congress


InterDigital, Inc., a developer of wireless technologies, demonstrated its “Fuzzy Cell” technology that improves cell-edge performance at the 2010 Mobile World Congress.

 
InterDigital’s (News - Alert) Fuzzy Cell technology, as stated, is a part of the company’s comprehensive suite of “Next Generation Cellular” innovations that combines advanced network topologies and spectrally-efficient air interface solutions for LTE (News - Alert)-advanced and more.
 
“Many wireless operators and customers are experiencing a substantial degradation of service quality caused by the ever-growing demand for mobile data,” James J. Nolan, executive vice president, research and development, InterDigital, said. “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.”
 
According to the company, advancements in HSPA and LTE primarily contribute to the increase in peak data rates and offer modest improvements in average performance throughout a cell. The company’s Fuzzy Cells is a technology that is said to address this and contribute to improve spectral efficiency and cell-edge performance.
 
In a Fuzzy Cell deployment, a device is said to connect to multiple sites at a time through the different sub-bands and continue to realize full system bandwidth. Here, the power levels and sector orientations of the different sub-bands are optimized for best performance.
 
Additionally, Fuzzy Cell technology also improves performance in indoors as it allows connection to more than one cell/sector at a time as available. It is said to deliver additional improvement over Fractional Frequency Reuse methods that are supported by current specifications.
