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.


Speed– Competition driving the demand for higher

bandwidth services– GPON, P2P Ethernet and Bonded VDSL2 w/

system level vectoring emerging as leading access technologies to deliver these bandwidths

Convergence– Leverage wide-scale FTTx broadband access

networks to serve residential, business, and mobile networks

– Increase reach of high-capacity Ethernet services to high-value enterprise and mobile services

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
