WHAT ARE HETEROGENEOUS NETWORKS?Heterogeneous Networks include a

combination of technologies:

› CDMA, WCDMA, LTE and Wi-Fi

› Different cell sizes

› Multiple Frequency Bands

› Multiple RBS types

› Different transport solutions

› Efficient methods for spectrum and

interference management

› One management view

› Low TCO – Self Organizing Networks

HetNet includes - but is far more than small cells!

USER BEHAVIOR IS CHANGINGTraffic is Moving Indoors and Into Venues

Provide a seamless experience! Think inside-out!

55-70%* of all mobile data traffic is generated indoors

Capacity is shared among users within each cell

Closeness to the antenna improves quality of the users experience

Closeness to the antenna improves quality of the users experience

True Mobile Broadband with “five bar” coverage

The user experience relies on the quality of the radio signals

The Office user

55-70%* of all mobile data traffic is generated indoors

The Venue user

Twitter recorded a new high of 12,233 TPS (tweets per second)

during Madonna’s Superbowl halftime show

The Starbucks user

Starbucks offers free songs, eBooks and other content

through your local Starbucks AT&T Wi-Fi network.
