1 4G (LTE) Roaming Experience_ Mobile World Congress 2014
2 Telefonica offers to customers of multiple partner operators in more than 15 different countries and during MWC in Barcelona in anticipation of the commercial LTE Roaming: 2 2
3 The Mobile Broadband Reality 1 Everything connected Internet on our daily life Mobility Broadband becoming a necessity 3
4 LTE has reached the entire world GSA forecasts 350+ commercial LTE networks by end % of commercial LTE networks have deployed LTE LTE user devices launched (by 132 suppliers) WORLDWIDE NUMBERS 268 LTE networks commercially launched in 100 countries! 56% more countries with LTE service since Ghana, Peru, Zambia and Cambodia are the latest nations to launch LTE service! million LTE subscriptions worldwide total: Q Source: INTERIM GSA Evolution to LTE report - February 5,
5 Telefonica s vision: end-to-end virtualization DEFINITION HOW IT WORKS? Roaming is the ability for wireless customers to automatically make and receive voice calls, send and receive data, or access other services when travelling outside the geographical coverage area of their own home network, by means of using a visited network. Both networks have a International Roaming agreement in place to permit this, once all testing and technical implementation are completed. Roaming IN: Usage by foreign customers of the Telefónica network Roaming OUT: Usage by Telefónica customers of other operators networks abroad Through the GSM Association standards have been set for seamless roaming constantly updated by the introduction of new services or technologies. Operators want to be able to offer the same services abroad as at home and same quality E2E. Roaming services have therefore evolved from basic GSM, to GPRS/EDGE, 3G/ HSDPA to now LTE. The introduction of new services or technology requires new network (IREG) and billing (TADIG) tests. Operators apply wholesale charges to each other. Every operator sets its own roaming tariff plans for its own customers. Within Europe, roaming has always been an easy target for common policy. Roaming regulation applies from 2003 and has become more restrictive over the years. Latest proposals head at the complete abolishment of roaming tariffs 5
6 Customer Benefits If the customer has usually LTE service does not want to fall back to 2G and does not want to fall back to 3G when is abroad GOOD OPPORTUNITY TO TELEFÓNICA TO PROVIDE BETTER SERVICE TO THEIR CUSTOMERS Telefonica is conducting several roaming tests with international operators currently and that it is looking primarily to partner with tier one operators. We are starting to sign commercial agreements SAME SERVICES ABROAD AS AT HOME AND SAME QUALITY End-To-End 6
7 Experience Scope TIME PLAN Special LTE Roaming Service will be offered during MWC COVERAGE Barcelona downtown and surroundings LTE Coverage Feb 2014 (1800 GHz) Additional LTE coverage in 2600 MHz in hot spots Rest of Spain with own LTE coverage of Movistar, mainly Madrid as first door for entrance to MWC. CUSTOMERS Media & Analysts: Authorities and Regulators Telefonica Executives & other partners Executives and Delegates 7
