eMBMS Training | evolved Multimedia Broadcast Multicast Service

eMBMS Training, evolved Multimedia Broadcast Multicast Service training

eMBMS training discusses this 3GPP standard and covers how it enables mobile networks to offer rich broadcast/multicast services. eMBMS Service was introduced in Long Term Evolution (LTE) networks supporting distribution of broadcast and multicast digital content and services such as streaming video for real-time services, broadcasting live events, TV programs, live streaming, sporting events, concerts, online interactive gaming, mobile TV, rich media services such as multiple cameras, replays, statistics, and popular events to multiple users simultaneously.

eMBMS training will give you an overview and a detailed technical background on eMBMS architecture, logical nodes, operations, air interface, eMBMS channel structure, resource allocation for eMBMS, service Reception in eMBMS and implementation options.
