The document discusses the need for a dedicated operational technology (OT) networking infrastructure in buildings separate from the information technology (IT) network. It notes key differences between IT and OT like the types of communications, users, planning processes, and bandwidth needs. The document recommends best practices for an OT network including separating it from IT, designing for coverage, performance and scalability, using VLANs and subnets, dedicated VPN access, Power over Ethernet where needed, and management by OT integrators.
