Mobile handset interference cancellation chips

Supplier News

PHILIPS Electronics and Cingular Wireless have reached an industry first with a successful commercial network field trial of single antenna interference cancellation (SAIC) chips for next generation GSM/GPRS mobile phones.

This new semiconductor technology improves voice quality, decreases download times for data and increases the number of calls supported on the network for greater all-around efficiency.

The technology will be part of Philips' cellular semiconductor baseband and system solutions offered to cellular handset manufacturers globally. The Cingular trials were conducted on cellular prototypes from Philips.

Philips' technology enables mobile handsets to remove interference from undesired signals while efficiently focussing on the signals from the most appropriate base station.

It provides network operators with shorter download times over GPRS data channels and offers more robust GSM communications, including Adaptive Multi-Rate (AMR) speech channels which translate into higher spectral efficiency allowing operators to carry more calls per base station.

As a result, network capacity can be increased and service quality improved for cellular subscribers.
