IRVING, Texas-Nokia Mobile Phones has developed a new feature called Acoustic Echo Cancellation designed to eliminate echo in wireless phone calls without sacrificing other voice quality factors like tone and volume level.
The advanced feature for Global System for Mobile communications 1900 MHz networks will be available as a software upgrade to Nokia’s existing infrastructure software. The system requires no additional hardware or operation and maintenance work, and it automatically recognizes data and fax calls, said the company.
“The Acoustic Echo Cancellation gives us the opportunity to offer higher voice quality than what we were able to do with the existing landline equivalent,” said Rob Rowe, director of engineering at Aerial Communications. “We have done extensive testing of this feature in our test laboratory, implemented it in our network, and the results are very positive.”
