LTE/SAE 1. 4G Experiences 3
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 11.5-12GB 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

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.

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 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
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

LTE Market Summary April 7, 2013 163 commercial networks in 67 countries 415 operators investing in LTE in 124 countries 361 operator commitments in 114 countries 54 pre-commitment trials in 10 more countries GSA forecasts 248 commercial LTE networks in 87 countries by end 2013 MVNOs are excluded WorldwideLTE subscriptions: 90.5 million Q1 2013. Forecast: 1 billion connections end 2017. 37
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
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
