Nortel Able to Deliver High Bandwidth Multimedia Over Any Major 4G Technology

Nortel said it has achieved the industry’s first live call over an Ultra Mobile Broadband (UMB) network delivering high-definition video and VoIP. With this demonstration, Nortel is the first in the industry to complete live calls using MIMO advanced antenna technology in each of the major 4G technologies - WiMAX, Long Term Evolution (LTE), and UMB.

The UMB call demonstrates Nortel’s ability to deliver a personal wireless broadband experience anywhere, anytime over 4G networks with high-quality services such as video-conferencing, live video-streaming, and VoIP. Using Nortel’s IP Multimedia Subsystem (IMS) and UMB technologies, crisp and clear voice conversations can be delivered with other high bandwidth applications running simultaneously on the network. Voice calls can also be maintained across multiple networks, meaning users can roam from UMB coverage to 2G without interruptions in their conversations using Nortel’s VoiceCall Continuity (VCC) based handover.
