4 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 for users on 3G. Vodafone (Germany): LTE usage almost all via dongles, is about GB a month, which is similar to its fixed-line usage. Dongle usage is a lot higher than smartphone usage, but Vodafone Germany s experience shows that speed and usage amounts are closely linked. 4

12 LTE FDD and LTE TDD TDD/FDD and Devices 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. LTE devices Routers 36% Dongles 24% Modules 15% Notebooks 5% Smartphones 14% Tablets 5% PC cards 1% LTE FDD 700 MHz MHz MHz MHz /1800/2600 MHz 36 LTE TDD 2300 MHz MHz 17 12

13 Examples of 4G LTE devices currently available in other markets 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.

18 LTE replacing home internet Verizon LTE good enough to replace your home internet? 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. 18

22 Driving Factors to Increase Data Usage 22

23 US Market example Higher traffic demands from LTE users LTE users more use video streaming than non-lte users in US market. 23

24 Specific Behaviors of Each Subscriber Group 24

25 Benefits identified by US businesses using 4G LTE 25

26 Advantages of 4G LTE over 3G and Wi-Fi 26

27 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 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 27

28 Benefits 47% of early LTE adopters report resultant cost savings 39% report increased sales. The creative, hotel and leisure, healthcare, IT and automotive and transport industries have benefited most widely. 28

38 LTE FDD and LTE TDD Most LTE commitments and deployments are based on thefdd mode. LTE TDD mode for unpaired spectrum is 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. 38

39 LTE FDD and LTE TDD 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). Operators deploying LTE FDD are expected to achieve 63% of the total LTE market, while LTE TDD operators are estimated to 37% percent share worldwide. 39
