New Femtocell Designs 'Sniff' Out Networks
By Paul Rasmussen
The arrival of self-organising wireless networks has taken a step forward following the announcement from picoChip that its new software reference designs provide the first integrated network listening (or sniff) capabilities for femtocells. The company claims its three designs will enable femtocells to detect WCDMA, GSM and TD-SCDMA networks.
According to Doug Pulley, CTO and co-founder at picoChip, the three new software designs target the company's single-chip femtocell device by automatically performing cell search and decode to enable self-configuration. In an all-3G context, they should permit handover between a femtocell and adjacent cells, and manage the handoff between a 3G femtocell and adjacent GSM base stations as users move in and out of range in a mixed 2G/3G network.
Separately the company's CEO, Guillaume d'Eyssautier, confirmed that it was about to close a fifth round of financing, having already raised US$71 million in four previous rounds from venture capitalists and other investors including AT&T, Intel and Samsung. d'Eyssautier did not reveal the size of the new investment, or whether the money was for a specific purpose.

Nokia Gains Patent Victory Over Qualcomm in Germany
By Lynnette Luna
As a key trial between Qualcomm and Nokia begins today over WCDMA patents, Nokia gained some ammunition in Germany. The German Federal Patent Court ruled that a Qualcomm patent pertaining to GSM phones was invalid and threw out Qualcomm's case against Nokia. The lawsuit was filed back in 2006, but delayed at Qualcomm's request.
"Nokia believes that this case is illustrative of the ongoing patent debate around open standardization. As an increasing number of technologies are integrated into new products some patent owners try to claim high compensation for patents that lack merit," Nokia said in a statement.
A U.K. court and the International Trade Commission have also ruled in Nokia's favor, saying Qualcomm's GSM patents are invalid. The GSM patent lawsuits between the two companies primarily stem from the impasse the two have over a patent agreement that expired in April 2007 pertaining to royalties Qualcomm charges for WCDMA chips. Both companies have filed a flurry of patent lawsuits against each other for both GSM and WCDMA in various U.S. states and across Europe. [FierceWireless]
