The role of DMR in improving worker safety.
Trunked radio networks provide demonstrable advantages for worker safety. Locational information can be another key element of worker safety, but there must be a solution to prevent data and voice interference. Several examples are given about how DMR makes a difference by improving worker safety.
Here's an excerpt from the full transcript of the above video.
Member: When we designed air trunk system, when I worked at North Anem, which is a nuclear power station redundancy was the key. Redundancy upon redundancy. If this goes down, then it goes to here. And if that went down, then somewhere else. What I did there, and it was a Motorola SmartNet system, and what I have done for the Tait system, is that I put in RF base stations. And in every dispatch center. I do not rely on any wires on the backup. It is all RF. It is just a desktop unit. It is a mobile unit attached to a 12-volt power supply. You can talk from there to the network just like you would a truck. Because if you go on the assumption, that if you lost all of your IP connectivity, the network was down, then that also means that all of our outage management, all of that is going to be down to the districts also, because all of that resides in our corporate office. So you are going to be opening up the districts for outage control anyway. You go back to the old maps. You go back to cards, [manually] keeping track of everything that you are doing. You put a guy on the radio, and he controls the crews from that one radio. So, yeah, it gets very simplistic, but you've got communications in the field.
Moderator: I think the use cases are absolutely everything. If you are talking about -- whose communication when the network goes down do you really want to have staying up? And then, what is the backup network for them? And I know that even if you are not talking about maintenance networks, that you are just talking about, say, SCADA networks, some of the utilities that I visited in the Middle East actually backed up these: the radio was the bottom line backup, but they had copper wire. They also had fiber, and all of these were fallback positions. So when we put a radio system in, it was really just one of the backup systems, or backup networks...
