== 5G is integrating verticals == 
* 2G
* 3G
* 4G
* 5G - 2020 Every vertical connected

* 5G needs to incorporate different characteristics and requirements of the vertcials

* Ratio of uplink to downlink in Bytes x propagation

* 5G empowering verticals
* Factors of the future
** IoT
** narrow cells
* Energy
** Smart grid
* eHealth
* Automtive
* Media & Entertainment

 	romper todo o tipo de soluções que não passem pela operadora

== 5G design principles == 
<br>

* Radio
** Leverage spectrum
** Enable cost-effective dense deployments
** Coordinate and cancel interference
** Support dynamic radio topology
* Network
** Create common composabel core
* Operations & Management
** Simplify operation and management
Cross:
Embrace flexible functionn and capabilities
Support new value creation
Build in security and privacy
