I wouldn’t be sure about this. I have firstnet on a work phone (EMT) and it’s rarely any better than my regular ATT device. While it does have low latency (sometimes 1ms) speed is not any different. I’m actually kind of mad because my department had Verizon before like your link, and it was way faster and worked in more places.
The wireless side of this is band 14, which is shared with regular consumers but FN customers get priority and the band can be restricted to FN only customers.
AT&T snags FBI business from Verizon with $92M FirstNet contract just days ago
FirstNet system is a unified communication platform to connect all levels of government and collect information during times of crisis.
Was created in 2012 after the Boston bombing.
Government agencies all are going to be linked through this system top to bottom.
This is basically a much faster private parallel internet that the public wont have access to.
very dangerous.
Who ever did this may be pointing this out
