Macro Cell Expansion and 4G Upgrade– Build more marcocell site towers– Upgrade 3G to 4G LTE/LTE-Advanced
Small Cell Rollout and Expansion– Reduced cell radius increases user capacity Metro, Pico and FemtoCell deployment Remote Radio Head/Distributed Antennas
Leverage Wi-Fi Access for Mobile Offload– Use of non-licensed spectrum frees up 4G
spectrum for capacity elsewhere
Enabling Mobile Services Expansion
“39% of mobile datawill be offloaded by 2015” - Cisco VNI
Cell site expansion
drives 1G/10G optical access
Small cell expansion drives 50-100M ubiquitous access
Street level small cell deployments augment roof top macro cell coverage.

This is a lot more expensive than this
This was designed for voice and this was designed for data
So, carriers are devising ways to keep voice on the current cellular infrastructure and move all data sessions to available Wi-Fi infrastructure

• Small cell, centralized baseband processing, and Wi-Fi offload technologies must complement macro cell improvements to meet mobile broadband demand
• Backhaul architectures must evolve to support a mix of residential, enterprise, and mobile backhaul service delivery
• vWLAN along with new Wi-Fi standards (e.g. Wi-Fi Passpoint) provide the scalability, interoperability, and functionality required to integrate licensed and unlicensed spectrum solutions
