2011년까지는 Voice가 Data보다많은 Traffic을 전송할 것임

1. Dominance of voice is still all-

encompassing for now

2. 2011 will be the watershed year

that data overtakes voice traffic as

networks undergo transformation

3. Operators must learn to cope with

the repercussions of the move to

a data-dominated world as traffic

and revenues become uncoupled

LTE Overview

• LTE Background & Concept

• CISCO LTE Strategy


The LTE Revolution

Radio Side (LTE –Long Term Evolution)

Radio 장비에서의 User throughput, latency 향상

Radio Network에 대한Simplification

Packet 기반 서비스 들에 대한 효율적 support: Multicast, VoIP, etc.

Network Side (SAE –System Architecture Evolution)

–Core 장비에서의 latency, capacity, throughput 향상

– core network simplification

–IP Traffic/Service에 대한Optimization

–다양한 access망 접속 허용

–Evolved Packet Core (EPC)
