7. 4G | So, is LTE enough?
Not today
• Initial coverage limitations
• Limited spectrum, and spectrum is expensive
• Mobile data demand continues to exceed supply
Not in the future
• Build‐out can’t keep up with projected data demands
• Cost per MB is lower on Wi‐Fi

8. 4G | What role will Wi‐Fi play?
Wi‐Fi is becoming an increasingly important and
integrated component of today’s mobile network fabric
Mobile broadband is not a replacement for Wi‐Fi; rather,
the two technologies are complementary 1
Wi‐Fi will be more relevant in the 4G era than it was in 3G
Heterogeneous Networks (HetNets) is the clear industry
direction to increasing cellular capacity and coverage
