LONDON Icera Inc. (Bristol, England), a developer of soft modems for mobile broadband, has announced the availability of IceClear, the company's "interference-aware" receiver technology.
IceClear uses signal processing algorithms implemented in software, to cancel the effect of interference from other cells, to deliver up to triple the previous user data rate, where it is poor, and improve cell site network efficiency.
Interference-aware receiver technology has been known to achieve substantial user throughput and cell capacity gains for some time, but until now has been expensive to implement. Because IceClear is implemented in software there is no additional silicon cost. "No other mainstream HSPA chipsets have delivered interference cancellation technologies in production products to date," the company said in a statement.
Until now, the mobile broadband user experience has tapered from the high headline rates achieved when the user is close to the base station, to much lower data speeds at the cell edge. Previously, the data throughput has been further seriously limited at the cell edge due to interference, referred to as dominant interference power, from signals of the same frequency and of similar strength, transmitted by adjacent cell sites.
In testing of conditions where one dominant interfering cell limits user throughput to a few hundred kilobits per second, IceClear multiplies the throughput by a factor of up to 3.6.
"Mobile network operators are focusing on and differentiating themselves through the quality and consistency of their mobile broadband services. They can now look forward to delivering dramatically improved user data rates on their existing networks in a matter of weeks," said Steve Allpress, chief technology officer of Icera, in a statement.
IceClear is included in the latest version of Icera's Adaptive Wireless soft modem providing a significant enhancement to customers with what is already independently recognized as the industry's top-performing HSPA mobile broadband technology.
