Interesting that it's the US-wide one; there are local and regional safety systems, too, which are heavily bid up by folks including Motorola.
Here in Seattle ever few years we approve another quarter billion dollar emergency network project. If our local cost is a quarter billion, $6.5B for a country-wide network seems like a deal in this day and age.

- SigmundA 10y agoThis is not typical public safety trunked radio stuff that Motorola usually does. This is basically a special LTE band (14 - 760mhz down, 790mhz up). Standard LTE tech using one of the lower frequency bands for better range and penetration but lower speed. Also the public safety modems in device will go up to 1 watt transmit instead of just 300 milliwatts of your typical LTE device. Most public safety agencies in US already using cell networks heavily for their in vehicle laptop / dispatch systems having contracts with Verizon or ATT this will just give them a dedicated band the public isn't using so it should stay up better even when the rest of the cell system is hammered due to a unexpected event. Probably includes dedicated backhaul bandwidth from the towers and static ip's for devices etc. Interesting note you can get a legal LTE booster that goes to 1 watt transmit to match FirstNet transmit power. Cradlepoint already has a FirstNet modem, thier routers are used in public safety vehicles already along with Sierra Wireless and Pepwave: https://cradlepoint.com/content/whats-new/band-14-module-public-safety-firstnet https://cradlepoint.com/content/whats-new/band-14-module-pub...
