LTE concept
› 3GPP Long Term Evolution (LTE) is a standard for wireless communication of high-speed data – Specified in 3GPP, Release 8 (2008) – Not just a wireless access, but an end-to-end network architecture
› Enabling ubiquitous (mobile) broadband access: – Facilitating broadband access a universal human right – Facilitating equal opportunity to information access
› Enabling true global mobility: – Always connected anywhere – Voice and data services
LTE – the game changer

LTE Drivers
NETWORKED SOCIETY: – Ausgrid, Australia: Smart grid network to use LTE – Ericsson and Akamai: mobile cloud accelerator
TV BROADCAST and VIDEO SERVICES: – LTE used by TeliaSonera to broadcast the Swedish royal wedding – China Mobile broadcasts the World University Games, from Shenzhen via LTE – More than 20% of all mobile broadband traffic is YouTube related!
INTERNET ACCESS, MOBILITY: – LTE to bring fixed-wireless broadband to rural Australia
Coverage up to Everest base camp!

ON, Self Organizing Network
Continuously innovating and evolving
Why SON
– high OpEx in some RANs, costly O&M › LTE must be better – SON defines requirements for lower O&M › mainly based on automation
ricsson main driver of SON in 3GPP
– standardization required for multi vendor and IRAT (Inter Radio Access Technology) hand over capability
ON available from first commercial ricsson release of LTE
