Two-way radio communications have been the standard for mission-critical wireless communications for nearly a century. The land mobile radio (LMR) systems of today are highly evolved and are very capable of providing reliable and secure mission-critical communications. However, these LMR systems have significant drawbacks. They are highly complex and expensive to deploy. The radio frequency (RF) spectrum in which they operate is crowded. And their ability to perform high-throughput data communications is almost entirely lacking.
The last drawback is particularly vexing for electric-power utilities. The critical nature of electric-power utilities has long been recognized and most are continually improving reliability in many areas. Critical needs for robust and efficient data-communications networks have emerged as utilities pursue increased reliability of electric-power delivery in their fast-changing environments. These include the smart grid, digital transformation, distribution automation, and advanced meter reading. New challenges have emerged as well, related to the quickly growing renewable energy sources, the expected exponential growth of electric vehicles, and new forms of energy storage.
