LTE and 5G
LTE: Foundation LayerAnchor users on LTE control channels
Pre-5G Fixed Broadband: Carrier Aggregation on top of LTE5G is NOT a stand-alone mobile network
5G Mobile Broadband: Carrier Aggregation on top of LTEBands below 6 GHz will be importantMigration will happen over time

Conclusions
5G Spectrum cost must be lower than 4G
Radios will transmit high power and will run hot
CPEs will be outdoors/in windows
mm-wave 5G will be highly targeted
Sub-6 GHz 5G will work better for mobile service
