In the world of electric utilities, privately owned communication networks remain the vehicle of choice for interconnecting assets in the Field Area Network (FAN). Public wireless technologies, such as cellular on the other hand, are not as widely used. By industry estimates (Navigant SGNC 2014), 80% of communication devices shipped to North American utilities in 2016 will fall under the private wireless category, while only 8% will be cellular based. This, in part, is due to common adoption barriers for cellular among electric utilities, which include misconceptions around the lack of security, reliability and performance. This paper will address those concerns by showcasing how cellular and private wireless technologies compare.
