5G: Key challenges
Peak data rate of 20 Gbps
User data rate of 100 Mbps Area Traffic capcity of 10Mbps/sqmtr
Higher data rate
Front-, Mid-, Back- haul
5GC <Backhaul> CU<Midhaul>DU<Fronthaul>RU
X-haul
1-10ms for eMBB
Low latency
5G may not get GPS connectivity at many sites and will be primarily dependent on transport layer
Timing (GPS less RAN)

9. Network Slice IoT (mMTC) Slice Broadband (eMBB) Slice
A network slice :
could span across multiple parts of the network infrastructure (e.g. terminal, access network, core network and transport network)
could also be deployed across multiple operators.
comprises dedicated and/or shared resources, e.g. in terms of processing power, storage, and bandwidth and has isolation from the other network slices.
IoT (mMTC) Slice
Broadband (eMBB) Slice
Low latency (uRLLC) Slice
Slicing will other verticals like automotive, residential, industrial robotics to build application in their domain after having got access to a slice with required characteristics like low latency, high user density etc.
Net-neutrality Slice
Infrastructure Layer

10. Application of Slice for Automotive (EV) vertical
V2X Slice (Visited)
V2X Slice (Home)
Slice Roaming
V2X Slice
Slice Analytics
IIoT Slice
Slice roaming will ensure that once you move from Karnataka to TN, your V2X slice also moves into the new geography seamlessly with you. If suppose the V2X slice of your car can help you to find the nearest pump in TN on the way and drive you autonomously there as soon as you run short of petrol and can take you to the nearest service centre in case your headlight for damaged and within in the factory move you to an automated IIoT area where a robot will replace your headlight while you take a nap!!!

Conclusion
Tower, power, space and location advantage can enable Discoms to generate addition revenue from telecom operators
Discom can have a key role in 5G
Discom should become a converged communication and electricity provider
Discom as a converged infra player
