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
Capacity is shared among users within each cell
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.

INDOOR COVERAGE ENHANCEMENTS = BRAND PROTECTION
COST CHALLENGES = ADD CARRIERS, TECHNOLOGIES
› HOST NEUTRAL DAS = EXPAND, MONITOR, MAINTAIN
› OEM’s = NEVER A COMPLETE SOLUTION
› WiFi = VENUE DEMAND, NETWORK PLAY, CONTROL?
LONG TERM ISSUES
› NETWORK DENSIFICATION = HETEROGENOUS DEPLOYMENT
› 150,000 SMALL CELL NODES + 100,000 INDOOR VENUES = PLAN?
