4. First PriorityTM
The only network that offers First Priority™ - a 24/7/365 priority and preemption solution for voice, text and data
First Priority™ is always on and will provide primary users with an evolving set of QoS, priority and preemption that will exceed anything previously available to first responders
FirstNet users are exempt from throttling in the country
Extended primary users can be uplifted to First Priority™ status on the FirstNet core
Top-level “incident priority” supersedes all other users on a temporary basis
Primary users have the ability to pre-empt all other users (except calls)
You have priority network access and preemption capabilities – every day on every call with First Priority™. This is not like priority being offered by a popular commercial network that says you’ll have it “when you need it”. First Priority is always on and because there are no speed limits on voice, text and data your network has no throttling – ever. Plus, you are always in control, so you manage both the levels of priority access and the elevation of other public safety users to higher levels when you need a hand.
First Priority included by default and mandatory on all FirstNet orders for Primary Users
provides the priority and preemption experience they require on the network
No level is subject to preemption
No additional costs to Public Safety
Supports Command infrastructure for Public Safety Organizations to allow to differentiate users based on
