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.

Blueprint for a future wide areamobile broadband network

Open initiative driven by vendors and operators Objective

Promote LTE/SAE as NGMN technology NGMN and 3GPP requirements taken as input to LSTI

Promote industrialization of LTE/SAE Stimulate development of LTE/SAE ecosystem

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
