FirstNet or FedNet as it should truly be called is another cellular telephone system with its emphasis on data rather than voice. What ATT rightly understood about the win to build the network is it will/has turned into a money sink for the users. Even with the ability to ruthlessly preempt other Band 14 users and access to ATT's other bands the envisioned bandwidth will not be available at the scene of a major incident. There are a little over 12 million "first responders" and another 18 million other emergency responders as defined by the Homeland Security Act of 2001. The present governance is almost entirely in the hands of law enforcement who don't always play nicely in the sandbox with fire and EMS. Don't even ask them if the utility companies deserve to be included, they are very much opposed. In a disaster situation the two things most needed are water and electricity and you can't get that from law enforcement, fire or EMS. If I sound a little bitter about it, it's because I spent a good many years arguing that no responder or class of responder does their job alone but was not truly heard by the first responders or the Commission. What the system lacks, and has been pointed out, is mission-critical voice communications. The cellular devices in use are a peer-to-peer connection while LMR or radio is a one-to-many. Say something on a channel and everyone on that channel in range hears that same message. That doesn't happen with cellular and, if and when it does come about it will be at the cost of the bandwidth needed for data.
