LTE usage compared with 3G

› NTT DoCoMo: LTE Smartphone users consume nine times more data than 3G users› MetroPCS (US): 40% of all MetroPCS gross additions in September were made up of 4G subscribers› SKT (South Korea): average LTE data usage in South Korea is higher than on 3G, with LTE users consuming 2.9GB of data on average a month compared with 1.2GB

4

2.9GB of data on average a month compared with 1.2GB for users on 3G.› Vodafone (Germany): LTE usage almost all via dongles, is about 11.5-12GB a month, which is similar to its fixed-line usage. Dongle usage is a lot higher than smartphoneusage, but Vodafone Germany’s experience shows that speed and usage amounts are closely linked.

948 LTE User Devices – July 5, 2013 (GSA report)

� Most LTE commitments and deployments use the paired spectrum(FDD) mode,

� LTE TDD: almost all countries have trials on networks operating in TD-LTE,

� LTE1800: several LTE terminals can operate in 1800 MHz.

• Many devices primarily aimed at consumers• Increasingly used in the workplace and often belong to employees.• Trend: ‘bring-your-own-device’, or BYOD.• Ex.: Samsung produces a version of Galaxy S3 for corporate use. It incorporates business features such as enhanced security, improved Virtual Private Network (VPN) connectivity and enhanced collaboration and calendaring.

• ….download the file nearly twice as fast

– What amazed us most here was that, not only did Verizon’s 4G LTE download the file nearly twice as fast as our home internet connection, but it also uploaded at over 10 times the speed.

Driving Factors to Increase Data Usage

Higher traffic demands from LTE users

LTE users more use video streaming than non-LTE users in US market.

Benefits identified by US businesses using 4G LTE

25

Advantages of 4G LTE over 3G and Wi-Fi

26

Experience and usage of LTE

• Experience in markets where 4G LTE has been launched suggests that widespread adoption by businesses requires five essential ‘enablers’: device availability and choice; reasonable pricing; clear awareness of LTE’s capabilities; applications that use its capabilities; and widespread network coverage. These are, or will soon be, in place in the UK.

• In South Korea (100% coverage within 9 months) 4G LTE penetration reached 18% of subscribers two years after launch

27

penetration reached 18% of subscribers two years after launch vital ‘enablers’:

1. Broad choice and availability of LTE-enabled devices

2. Extensive network coverage

3. Reasonable and attractive pricing

4. Awareness of LTE’s performance and applicability

5. Applications that capitalise on the capabilities of 4G LTE

Benefits

• 47% of early LTE adopters report resultant cost savings

• 39% report increased sales.

28

• The creative, hotel and leisure, healthcare, IT and automotive and transport industries have benefited most widely.

• LTE TDD mode for unpaired spectrum is

complementary.

38

complementary.

• LTE TDD is an evolution for TD-SCDMA (deployed in

China).

• Part of the 3GPP standards with commonalities

with LTE FDD and offers comparable performance

characteristics and same high spectral efficiency.

• LTE FDD subscribers: from 12 million in 2011 to more than 264 million

in 2015 (most in Western Europe, Japan, and the US);

• LTE TDD subscribers: from 6 million in 2011 to nearly 158 million in

2015 (leading operators in Asia/Pacific and North America, including

China, India, Korea, Malaysia, Australia and the US).
