You earlier had developed feature for CUCM-CER product line, in category of location based services, wherein , Cisco WLAN controller were configured in CUCM system and a sync service will infer access points ( AP ) deployed and configured at physical location of office space.
Voice call ( originating from VoIP phone(wireless) ) going via AP helped in tracking precise physical location of caller , thereby making emergency res ponders quickly get to the incident site.
A white paper of its deployment , and best practices recommended by Cisco can be found here, towards the last pages

This feature is way back in 2016.
This is good starting point of thinking in terms of solution deployement from hardware perspect.
Now in 2020, people are talking about SDN - Software Defined Networks.
Before jumping into new technology, lets see

Analogical thinking
(a)
Similar to virtualization jargon ( Iaas,Paas,SaaS,AaaS ) now SDN can be thought of as
NaaS - Network as a Service
SDN is for network routing protocols aware engineers; who can evaluate (service level argeement) SLA and mapping to network (quality of service) QoS parameters for the enterprise applications.
Over the week, was reading of LiFi networks and spatial modulation and network segregation . So one catapulting use case in near future would be to have separate networks, for
a) having a separate network for IoT traffic
b) having a separate network for enterprise app traffic
c) having a separate network for secure /confidential data traffic
(b)
Network administrator role is maturing to be called infrastructure specialist and probably a SDN specialist in near future.
(c)
One of NSO objective in CWM project , would also be to automate the provisioning of switches and routers and have better control on packet routing and paths in production environment, which also maps to the basic theme here.
