Scope of the PoC is to demonstrate the MW model in context ofmmWave products:

- Reference model (TR-532):

• https://login.opennetworking.org/bin/c5i?mid=4&gid=0&rid=5&k1=2088

- Reference architecture /functional:

USE CASES (proposed)

eNB extensibility

P2MP µW/mmW model

Ethernet; L2VPN

IP/MPLS; L3VPN

Self-backhauling

1588v2 TC (phase & freq)

Adaptive QoS

Network Slicing*

* Network slicing uses the

same network infrastructure,

but a “slice” is created for a

particular industry for a

particular need at a particular

time
