Field Area Networks based on IP over radio with the bandwidth necessary to support multiple applications over a common radio infrastructure are now common in utility networks. IP based SCADA products bring protocol, security, and management needs that drive expectations for radio system capacity and latency requirements with LTE and NB-IoT radio technology often seen as ideal. LTE systems both public and private, provide many of the needed characteristics to address utility needs but care is needed in considering the actual applications to be supported as capacity, latency, cost, and security must all be considered. Alongside LTE, private point multipoint private narrowband radio is complementary technology for field networks with certain advantages and a history of reliability, redundancy, and resilience. This presentation will review LTE, industrial IoT, and private radio solutions as well as the equipment specifications necessary for utility critical infrastructure including dual SIM operation, IEEE 1613, and IEC 62368-1.
