This is where LTE / SAE enters the game …

LTE (Long Term Evolution) designates the evolutionary path of WCDMA / HSPA defined by 3GPP towards the next generation of mobile cellular radio technologies.

SAE (System Architecture Evolution) designates a modified and simplified, all IP based network architecture optimized for packet data transmission.

Cost advantages compared to other systems

Due to:

• High radio bandwidth (20MHz compared to e.g. 5MHz)

• Flat IP based network architecture (2 rather than 4 network elements)

• Built-in IP backhaul connectivity (based on Carrier-Ethernet)

• Smooth network & service upgrade(Value proposition of NSN solution: SW upgrade of BTS to eNB)

Hot areas of interest for LTE today


The Digital Dividend for mobile broadband will bridge the Digital Divide

• Radio signal range @ 800 MHz significantly larger than @ 2100 MHz

• Less cell sites required to achieve area coverage

• Radio networks @ 800 MHz require significantly less investment

Intensive use of Self Organizing Networks

• Configure & optimize the network automatically• But allow the operator to be the final control instance

• Parallel operation of LTE with 2G and 3G networks• Large number and complex structure

of network parameters• Expanding number of Base Stations• OPEX reduction - Reduce human interaction

LTE / SAE will create new business opportunities and value chains in a dynamic market


Leading Mobile Network Operators have expressed their decision for LTE / SAE

LTE ist aus Sicht von Vodafone … die

bevorzugte Technologie für Mobilfunknetze der 4.

Generation. (Hartmut Kremling, Vodafone

Deutschland)

T-Mobile will LTE, sobald es marktreif ist, sofort breit anbieten. (Hamid Akhavan,

T-Mobile)

LTE brings the promise of bringing extra capacity, better spectral efficiency

at an enhanced cost factor. (Jaime Lluch,

Telefonica)

China Mobile, Verizon Wireless and Vodafone Trials Confirm LTE as a

Next Generation Candidate for Seamless Global Mobile Services

Verizon Selects LTE As 4G Wireless Broadband

Direction


LTE / SAE is supported by leading CSPs and manufacturer to form a large ecosystem

Many leading mobile network operators have decided to go for LTE / SAE(NGMN alliance)

All leading network manufacturers have their LTE / SAE programs
