Mobile Broadband Journey • Wireless is the most personal and pervasive mean to access Broadband Services • The Operator’s challenge is to continue enhancing the User’s experience Average Radio throughput per user Average Core throughput per user Average throughput per user 18 LTE 20 MHz 16 LTE 10 Mhz 3GPP Evolution 14 12 Low latency Avg contemporary users CN Simplification 10 Mbps Throughput 8 6 Ave # of contemporary user HSPA High latency 4 2 0 Bandwidth Time From Service to Experience through a harmonic and smooth evolution of the entire delivery chain Presentation title in footer
The E2E Data Delivery Chain Continuous Evolution Radio Capacity Core Capacity & Simplification Yesterday LAN Mobile NodeB RNC SGSN GGSN UMTS Improve performance, limiting investments Now FTTN and MW Ethernet Internet LAN Mobile NGME NodeB RNC Interconnected Networks SGSN HSPA+ Direct Tunnel Tomorrow Continuous performance improvement and network simplification VAS LAN Mobile eNodeB A-GW Personal/ Private Clouds MME LTE HSPA+, Direct Tunnel and an enhanced backhauling capacity pave the way to LTE, currently the best performing radio technology choice Technology Meeting
Why LTE • Enhanced network capacity • Architecture renewal with Full IP focus • Multiband scalable Radio Technology • Improvements on connection scalability • From Smartphone to the “network of the things” • Heterogeneous NW – from macro site to femto • Additional wireless resources • More Spectrum (multiband) more efficiently used… • Wide area pervasive coverage requires low bands (<1GHz) 4 Presentation title in footer 29 November 2014
LTE Radio Network: the Vodafone Approach • Network Simplification at the Edge of the Network • + • Best performing radio technology option • = • LTE over Single RAN RRH (Software Defined Radio) • RAN Technology Digital Revolution • Technology agnostic Base Station Box • Simplification • Flexibility • Full IP based • Radio Remote Head (RRH): Software defined Radio • Power efficient (“green” network) IP to CN Common Base band 5 5 Presentation title in footer 29 November 2014 29 November 2014
LTE-Advanced Wider bandwidth for higher performance Exploiting more sophisticated Radio Transmission schemes Self-Organising network to efficiently handle heterogeneous network Relay to boost pervasive coverage Beyond LTE: Never Stop Evolution 6 Presentation title in footer 29 November 2014
Conclusion • Mobile Broadband demand will put under stress of the available capacity • Technology will be the enabler of Mobile Broadband but its success is rapidly exposing its limits • Long-term success is not based on any one innovation and it is not based on any one company • It is based on a harmonic growth of the entire data delivery chain • It is based on how the industry works together • Network operators • Equipment manufacturers • Device makers • Software providers • Regulators Presentation title in footer
