WHAT ARE <strong>HETEROGENEOUS</strong><br />
<strong>NETWORKS</strong><br />
Heterogeneous Networks include a<br />
combination of technologies:<br />
› CDMA, WCDMA, LTE and Wi-Fi<br />
› Different cell sizes<br />
› Multiple Frequency Bands<br />
› Multiple RBS types<br />
› Different transport solutions<br />
› Efficient methods for spectrum and<br />
interference management<br />
› One management view<br />
› Low TCO – Self Organizing Networks<br />
Coverage<br />
Speed and<br />
low latency<br />
Capacity<br />
Low TCO<br />
HetNet includes - but is far more than small cells!<br />

USER BEHAVIOR IS CHANGING<br />
Traffic is Moving Indoors and Into Venues<br />
The Starbucks user<br />
True Mobile Broadband with “five bar” coverage<br />
Starbucks offers free songs, eBooks and other content<br />
The user experience relies on the quality of the radio signals<br />
through your local Starbucks AT&T Wi-Fi network.<br />
The Venue user<br />
Capacity is shared among users within each cell<br />
Twitter recorded a new high of 12,233 TPS (tweets per second)<br />
Closeness to the antenna improves quality of the users experience<br />
during Madonna’s Superbowl halftime show<br />
Provide a seamless experience! Think inside-out!<br />
The Office user<br />
55-70%* of of all all mobile data traffic is is generated indoors indoors<br />
Networks evolve to HetNets to provide a consistent user experience<br />
