Consequences of band fragmentation

for LTE devices

• Vodafone experiences and plans for LTE devices

• Providing superior LTE devices while

accommodating the battery and multi-band

requirements of LTE networks

• FDD vs. TD-LTE – accommodating both variants in

mobile devices

• Vodafone band requirements for devices

Experience from initial device launches

Positive Surprises : • Impressive user experience • High data rates • Low latency • Stable and reliable • Surprisingly few interworking issues

Learnings: • Complete new system, significant impact

on e2e chain (SIM, device, radio, transport, core, IT systems, process)

• Inter system mobility complex, requires integrated network with upgrade of all legacy networks

• Significant testing effort, esp. Mobility • CS-FB works, call setup time acceptable,

but limitations

Open Issues: • Device Cost • Battery Life • Fragmented voice solutions • Spectrum Fragmentation

Informa Telecoms LTE survey shown on last year in Amsterdam

Why are there so many LTE frequency bands ?

• Value of spectrum

• Regulation, different bands in different regions

• Legacy – e.g. military use, analogue TV

C1 – Public | 24 May 2012 11

What will customers expect from LTE devices ?

Let‘s take an example of a 3G product

today, with world-wide compatibility:

iPhone 4s supports:

• 4x HSPA

• 2x CDMA

• 4x EDGE

To achieve similar global compatibility and roaming,

6-8 LTE bands required in addition

Spectrum

Vodafone foresees a convergent FDD/TDD scenario in an

increasing number of our markets

• We have acquired 2600 MHz TDD spectrum in Germany, Spain and

Portugal

• LTE service using FDD in Germany since December 2010, Portugal since

March 2012

Chipsets

• All major chipsets manufacturers support both FDD and TDD in hardware today

• Full commercial availability of TDD chipsets typically lagging FDD by ~1year

Devices

• Commercial TDD devices available

• Some devices declare FDD & TDD capability

Features

• Handover between FDD and TDD not yet available

• Co-existence FDD/TDD on same device yet to be proven commercially

• FDD/TDD Carrier aggregation not currently on roadmaps

% Band support existing LTE terminals

Source: GSA website, January 2012

•Today converged FDD/TDD terminal support is limited.

•We need to continue to drive converged FDD/TDD terminal availability

How is the ecosystem evolving to support FDD/TDD convergence in the devices?

Vodafone LTE frequency band requirements

24 May 2012 *) Bands, which might or will be required, but timeframe unclear Note: All Timelines are indicative, subject of change

2010 Band 20 (800 MHz): Deployed in Germany

2011 Band 7 (2600 MHz): Deployment in Portugal and Germany

Italy, Spain, SFR in France acquire LTE spectrum

2012 Band 3 (1800 MHz) : Spectrum available in many markets,

re-farming from 2G in 2012

2013 Band 13 (700 MHz): Roaming to US, Verizon Wireless

2014 Band xx (700 MHz): FDD for Asia-Pacific region

2015 Band 38, (2600 MHz): TDD for Europe including FDD–TDD convergence:

FDD and TDD on the same device, including handover and co-existence

Uncertain *)

Band 8 ?

Band 1, EU, roaming Japan ?

TDD: Band 40/41 roaming to China, LTE in India ?

Vendors, which enable LTE Multiband & Multimode devices will be most successful

Conclusion

• LTE will require Multiband devices, to facilitate economies of scale

and global roaming

• HSPA+ and EDGE support on devices required for coverage

• Solutions need to be cost effective and small

• No Compromise on RF performance

• Current focus is FDD, but FDD+TDD support will be required,

including co-existence and interworking
