Qualcomm Says VoIP Will Work On Mobile Networks

Qualcomm announced Wednesday that it has successfully demonstrated that fully mobile VoIP calls.
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).

"The full mobility success of these VoIP field tests represents another step toward the convergence of IP and mobile data services with landline wide area IP networks," the firm's announcement stated. "Operators will be able to efficiently merge their wireless and wireline networks based on IMS… operators are able to use their network capacity in a much more flexible manner through the dynamic allocation of capacity to an ever-increasing array of 3G services."
