Product Description
FirstNet is a high-speed, nationwide wireless broadband network maintained by AT&T for public safety communications. This network has dedicated cellular frequencies for law enforcement, firefighters, ambulances, and other first responders and public safety agencies.
The Uniden UM50 FN cell phone signal booster helps you stay connected and experience fewer dropped calls, undelivered texts, and missed email messages at all times, including during emergencies. It amplifies FirstNet band 14 and AT&T band 12.
Stay connected farther from cell towers and experience fewer dropped calls, undelivered texts, and missed email messages. Data-driven navigation and other apps will perform better in remote areas with weak cell service and obstructions between your car and the cell tower.
The Uniden UM50 FN is the only mobile cellular booster that works with AT&T’s FirstNet network for first responders.
Installation of the Uniden UM50 FN can be completed in about 30 minutes. (See Documentation, below, to download the installation guide.)
