Flat All IP Architecture for Cost Reduction and Performance Reduce CAPEX and OPEX Costs Higher Network Performance
Efficient IP routing - reduce Latency (20 ms e2e RTD) Increasing Throughput (Peak @ 100/50Mbps DL/UL) Fast state transition time (enhanced Always-on) Less than 50ms transition from dormant to active
What is LTE?
Peak Performance DL OFDM/OFDMA in the DL
Spectral Efficiency (2-5x Rel6) Resistant to multi-path interference
MIMO (Multiple Input Multiple Output) Antennas Doubles the throughput Deployment simplicity
Power Efficient UL SC-FDMA Lower PAR
Longer mobile battery life Larger cell coverage
Collaborative (Multi-user or Virtual) MIMO Simplifies mobile implementation 80% capacity gain in uplink

Verizon Selects LTE As 4G WirelessBroadband Direction, Nov 2007
We expect LTE to form a key part ofVodafones future technology strategy,Steve Pusey, Vodafone Global CTO.
The companys move toward a 4Gnetwork is driven by our vision ofpervasive wireless Internet connectivityand mobility,.......we believe LTE is thebest technology with global scale to deliveron the promise. Dick Lynch, CTO VerizonComms.
GSM Association votes to support LTE, Nov 2007
Rob Conway, CEO of GSMA, announced the association's backing of LTEduring a speech at the GSM Association's Mobile Asia Congress in Macau,China, and called on the International Telecommunication Union (ITU), theleading United Nations agency for communication technologies, to ensurethe industry wins the spectrum needed to offer mobile broadband.
GSMA said it will work with other companies and organizations developingLTE technology, and start working with the NGMN (Next Generation MobileNetworks) initiative.

Summary LTE will be ready for Commercial deployment
in late 2009 Many vendors will enable operator transition
to LTE in a progressive, scalable, and costeffective way protecting investments inexisting technologies
LTE will allow operators to deploy competitive,revenue generating applications costeffectively to all subscribers
Many vendors are focused on IMT-Advanced(4G) deployment options for seamless inter-and intra-technology mobility and real-timeapplications for converging network value
