LTE Concept


A common evolution path…

Long Term Evolution (LTE) is the next generation broadband wireless technology for 3GPP

and 3GPP2 networks

What is LTE ?

OFDMA

MIMO

Flat IP

Robust modulation in dense environments

OFDMA (DL) / SC-FDMA (UL) Increased spectral efficiency. Simplified Rx design Cheaper UE

Scalable - go beyond 5 MHz limitation

A taste of 4G… …based on highly efficient technologies

Enabling new applications, lowering cost

Peer to peer applications requiring high throughputOnline gamingFlat fee trend

Increased link capacity

Multiple-input, multiple-output UL& DL. Collaborative MIMO (UL).

Overcome multi-path interference

Flat, scalable

Short TTI: 1 ms (2 ms for HSPA). Backhaul based on IP / MPLS transport.

Fits with IMS, VoIP, SIP

* Orthogonal Frequency Division Multiple Access
