As existing celluar towers are updated, and new ones are erected to provide or improve service, I can see most of the LMR users migrate to the RF bands that will be interconnected between these towers.
I see the main effort will be to develope a way to manage site loading, when you have users travel away from the home area they talk onto the system, a remote area, and drag their talk-groups and not overload the traveled to areas RF channels.
What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
