Beautifully thought architecture. Looking forward to work on this tech as soon as possible.

Hoang (Google) via LinkedIn 2016-01-21 10:04:13

Looks interesting.

Thank you for sharing

No doubt that Network Slicing will be a reality in the coming years... it´s the natural evolution path for Telcos to capture new IoT businesses

Nice one, looks very intresting.

Great slide !

Thanks for sharing. Should be interesting to see how equipment vendors implement 4G/5G interoperability.

Akhilesh (Cisco) via LinkedIn 2016-02-11 14:50:07

This is great slide

Many thanks for your efforts and guidence provided to all tech guys...great job

Good job! You may want consider the following modification for network slicing. I do not thik there will be separate radio AU for each service. Also the front haul is likely to be sereral baseband streams multiplexed using fibre optics. The cloud unit again is not multiple function but a single function that allocates resources and routs the baseband stream to the appropiate "slice" for

Nice approach...


I have question here,


Is it AU/CU will take the responisibility to identify the service ..as Voice/DATA/IoT and handle further processing accordingly ?

kamal 2016-12-21 23:43:08

Don't agree Wilson that the F.O to be the fronthaul, it will be IP based and that was tackled above under "save fronthaul cost" keping the latency critical functions at AU

Vinit Shandilya 2017-01-13 21:13:42

What is the functional difference between RU and AU?

suman sarkar 2017-02-22 22:52:20

what is CO ?what is denotes ?

Nicely showing the comparison in brief..
