Call over ultra mobile broadband network

Friday, 29 June, 2007

Nortel has claimed to achieve the industry's first live call over an Ultra Mobile Broadband (UMB) network delivering high definition video and VoIP.

The UMB call demonstrates the company's ability to deliver a personal wireless broadband experience over 4G networks with services such as videoconferencing, live video-streaming and VoIP.

Using 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.

MIMO is an advanced antenna technology that uses the OFDM modulation technique to carry heavy traffic across a wireless network even in surroundings where there are physical obstacles barring the way of the wireless signal, such as the clusters of tall buildings or mountainous terrain. These technologies can deliver fixed and mobile broadband services with minimal infrastructure.
