Why LTE? the demand for new MBB services
Over 10 million articles and over 6 million registered contributors on Wikipedia globally
45% of US and European workers are away from their desk more than 20% of their time
Over 4 billion songs,125 million TV episodes and 8 million movies have been purchased and downloaded from iTunes
412.3 years = Time it would take to view all of the material on YouTube.
More than 100 million video views are generated on YouTube every day.
The number of text messages sent and received each day exceed the population of Earth.
If Facebook is larger then Russia, with over 150 million active users.

Why LTE? traffic growth in the USA
Source: “Managing Growth and Profits in the Yottabyte Era”,Chetan Sharma, July 2009. One Terabyte is 1000 gigabytes.
Ericsson's researches say that of the estimated 3.4 billion people who will have broadband by 2014, about 80 percent will be mobile broadband subscribers – and the majority will be served by High Speed Packet Access (HSPA) and Long Term Evolution (LTE) networks.

What does LTE mean?› LTE is an acronym for Long Term Evolution and refers to the recent Work
Item in the 3GPP standards body concerned with the evolution of the Radio Access Network.
› The evolutional course that has lead to LTE includes GSM/EDGE, WCDMA and HSPA Evolution (a.k.a. HSPA+)
› The LTE standard was first released in 3GPP Release 8.

What does sae mean?
› SAE is an acronym for System Architecture Evolution and represents the set of 3GPP specifications regarding the evolution of the Mobile Core Network.
› The objective of the SAE specifications is to define the future core network needed to support the services furnished by the LTE access network with a simplified architecture (with respect to the current 3G core network.)
› LTE and SAE are two aspects of the same evolution of the next generation mobile radio network.
