SAN DIEGO—Qualcomm Inc. said it successfully demonstrated fully mobile Voice over Internet Protocol calls over its EV-DO Revision A technology.
The announcement is notable as Sprint Nextel Corp. has announced plans to launch EV-DO Rev. A technology by next year. Industry watchers have previously discussed the potential for VoIP over EV-DO Rev. A networks.
Qualcomm said it showcased Internet-based voice calls over mobile, pedestrian and fixed environments using commercial-ready, application-specific integrated circuits in prototype handsets and networks. The technology could enable carriers to migrate voice services to IP-based platforms, thereby creating a common service platform for voice and data, Qualcomm said.
The field tests involved 62 simultaneous calls conducted over CDMA2000 1xEV-DO Rev. A networks within a single 1.25 MHz channel.
“Operators globally have committed to the rapid deployment of CDMA2000 EV-DO Rev. A,” said Roberto Padovani, Qualcomm’s chief technology officer. “These tests prove EV-DO Rev. A’s capability for delivering high-capacity, high-quality VoIP over 3G mobile broadband networks.”
