COUNTRIES INVESTING IN LTE*
Eastern Europe
• 37 commercial network 7 thousand
launches in 21 countries 0.18%
USA/Canada
Western Europe
• 185 network commitments in 3.3 million Asia Pacific
103 thousand
66 countries 392 thousand
2.71%
10.34%
• More than 103 commercial
networks by the end of 2012

BEYOND THE DEPLOYMENT OF LTE MACRO BTS
EMERGING NETWORK CONCERNS
• Macro cells are spaced for good
“overall” performance; weaker at the
cell edge
• Numerous factors make it difficult to
place new macro cells; zoning
restrictions, real estate, expense, etc.
• Certain bands are inherently better
performers than others
Heterogeneous Networks Address All of These Needs

WIRELESS DEPLOYMENTS
KEY UNDERLYING NORMS
EXAMPLE HEAT MAP BASED ON LARGE US CITY
• 2%-3% users generate 40%-50% Traffic:
of mobile data traffic
• 60% - 70% mobile data generated
by nomadic users, indoors
• 1 sector often carries the bulk of
the traffic
Small Cells and DAS are Specific Solutions for Specific Problems
