Qualcomm Offers QChat Technology for Mobile Phones Using VoIP Architecture on 3G CDMA Networks

date: January 11, 2002

The QChat software application is a product within Qualcomm Internet Services (QIS), a division of Qualcomm Incorporated, and was publicly announced today.

QChat handset and server software allow users to almost instantaneously connect with other QChat users on 3G Code Division Multiple Access (CDMA) systems anywhere in the world with the push of a button. It provides half duplex communication between QChat-capable phones. It enables one-to-one (private) and one-to-many (group) calls over 3G CDMA networks.

QChat uses standard voice-over Internet protocol (VoIP) technologies. This means sending voice information in digital form over IP-based data networks (including CDMA) in discrete packets rather than the traditional circuit-switched protocols of the public switched telephone network (PSTN).

When offered by a wireless carrier on its 3G CDMA network, QChat allows PTT functionality for subscribers of QChat-based services on their BREW-enabled wireless phones.
