Qualcomm Says VoIP Will Work On Mobile Networks

Qualcomm announced Wednesday that it has successfully demonstrated that fully mobile VoIP calls can be carried out over multiple communications environments including mobile and fixed.

The tests, said Qualcomm, were conducted using its CDMA2000 1xEV-DO Rev. A technology and prove that a mix of voice and data can be delivered to mobile customers who will be able to access realtime audio, video, and data in a heightened multimedia experience.

Qualcomm said the tests will pave the way for network operators to conduct large scale commercial trials of the advanced technologies. Major users of Qualcomm's EV-DO technology in the U.S. include Verizon Wireless and Sprint.

Qualcomm said the field tests were conducted within a single 1.25 MHz channel and resulted in capacity gains 30 times greater than mobile analog voice. The firm said it used commercially available ICs in test handsets and networks.

The company noted that its tests used VoIP over EV-DO Rev. A, leveraging session initiation protocol (SIP).
