Everything goes mobile –
today mobile voice, tomorrow mobile data
• Today, Mobile is replacing Fixed
Networks for Voice
• In some markets mobile voice
minutes already exceed fixed
voice minutes
• However, the real game is data:
In fixed networks, voice is only a
fraction of the overall data volume
• Customers are getting used to
bandwidth-demanding services,
e.g., “YouTube”, MySpace, …
• And they want to have it anytime,
everywhere – on the move

Our aim for the next decade
2010
• Be prepared for the uptake of mobile data
• One mobile network for voice and data
2020
• Fully consistent broadband user experience (DSL as benchmark)
• ‘Always on’ experience without significant network overhead or
reduced terminal battery life
• Make Internet/user the limiting factor – not the access system!

Some history: The GSM success story
• GSM: 2.1 billion subscribers across 920 networks in 222 countries & regions
• GSM was driven by Governments as show-case for the European Union
– created momentum to challenge many previously national regulations & processes
– Terminal/infrastr. testing, approval, and certification were unified on European level
 Important prerequisite for the free circulation of mobiles
• GSM offered a truly new & important feature: Roaming
– Service obligations from the beginning: same service everywhere
– Frame for billing: revenue insurance for operators
• Standardization was done by operators, vendors and EU government
 Operator's view was considered sufficiently

Some history: Lessons learned from UMTS
• UMTS still based on legacy core network
 Stated promises for high-speed data transfer could not be fulfilled
• Standardization mostly driven by vendors
 Operators' view was not considered sufficiently
• Targets and business model not clearly defined
• Sufficient quality of standards only reached after long period
• Mobiles were too late: market penetration & quality did not meet expectations
– Too many options resulting in high integration and validation effort

Next Generation Mobile Networks (NGMN)
• Initiative of a group of leading mobile network operators
• Vision:
– Provide a technology vision for broadband wireless service delivery beyond 3G
• Mission: Create an ecosystem for next generation mobile networks
– Address all key factors for success (Business, Service, and Technology)
– Bring together all members of the mobile ecosystem: network infrastructure,
terminal, and chipset vendors, test system manufacturers, regulatory bodies,
application developers, and service providers
• However, as a lesson learned from UMTS, operators speak first
– Drive standardization by setting targets well in advance ( NGMN white paper)
– Drive industry by articulating not only technical but also business vision

Operator's key requirements
• Cost-efficiency requirements
–
–
–
–
Efficient reuse of existing assets (sites, antenna systems, spectrum)
Equipment sharing between network operators (e.g., access network sharing)
Standardized Operations & Maintenance (O&M) platforms, increased automation
Transparent Intellectual Property Rights (IPR) regime
• Functional requirements
–
–
–
–
–
–
Best-in-class radio performance & well-engineered network architecture
Optimized end-to-end Quality of Service (QoS) architecture
Seamless mobility
Efficient always-on support
Roaming and interconnection for IP-based services
Security

Intellectual Property Rights (IPR)
• Today, IPR accounts for up to 20% of the 3G terminal price
(with any new radio technology adding on top)
Background
• IPR has become a strong business asset for some big players
• New role "Patent Pirate":
Smuggle patent into standard and retrieve royalties
• IPR situation even more complex due to intransparent cross-licensing
("I don't charge you if you don't charge me!")
NGMN requirements
• Successful NGMN ecosystem requires predictable and limited IPR costs
• IPR costs have to be known prior to any technology decision

• Improved spectral efficiency – 2-4 times higher than HSPA
• User data rates: up to 100 Mbit/s in downlink and 50 Mbit/s in uplink
• End-to-end latency less than 20 ms
• Efficient support of IP Services (incl. VoIP)

High level system architecture
• Access-agnostic packet-only core network
– Serves a variety of radio technologies
– In the beginning, co-existence with
CS-segments of today's 2G/3G networks
(the latter will phase out over time)

Spectrum for NGMN
• Existing spectrum (e.g., 900/1800/2100 MHz in Germany)
– Spectrum can be shared by NGMN and legacy systems, but only with lower
bandwidth options of NGMN
– Increasing 3G traffic will saturate UMTS core band spectrum (2100 MHz)
 More spectrum with higher bandwidth required
• Most likely frequency bands for NMGN 20 MHz carrier
– UMTS extension band (2500 -2690 MHz)
– UHF-Band 470-860 MHz (Digital Dividend)
• Allows for efficient wide are coverage
• Usage for mobile has to be agreed by ITU-R World Radio Conference (WRC)
