Unicast and Broadcast: Complementary for Unlimited Mobile TV

Unicast is communication between a single sender and a single receiver over a network. An earlier term, point-to-point communication,

Select the Technology that Fits You Best

is similar in meaning to unicast. Typically, current 3G networks are unicast, which means that there are as many mobile TV signals as there are number of viewers simultane- ously watching a given program.

By contrast, broadcast is commu- nication from one sender to all potential receivers in a given area/region.

To deploy and integrate a mobile broadcast overlay with your network for a truly mass-market mobile TV offering optimized for your market you must address many challenges:

•What spectrum is required?

•Which standard is most appropriate?

•How can you achieve your target coverage?

•Can you reuse your existing assets?

•What is the best way to combine services?

Alcatel-Lucent has addressed these and other technology challenges with the Unlimited Mobile TV solution. This solution makes optimal use of existing network investments and resources and combines them with the best technical capabilities of various technologies and spectrum options to deliver a complete end- to-end solution designed to be easily adapted to your needs.
