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
