The Cellular Signal Booster for Firstnet Emergency Communications

Cel-Fi is a member of the Safer Buildings Coalition, an independent organization focused on advancing policies, ideas, and technologies that ensure effective in-building communication capabilities for public safety personnel and the people that they serve.

With the introduction of the FirstNet network for Public Safety Communication Devices creates an amazing opportunity for reliable communication in emergency situations. But, legacy equipment does not support the FirstNet dedicated band. Because of this Cel-Fi has committed itself to engineering a cellular solution that works with FirstNet.

The Cel-Fi GO RED FirstNet Booster delivers cellular coverage in buildings for emergency communications from police, fire, and medical personnel. Cel-Fi GO RED with the Cel-Fi Antennas is the best way to ensure coverage in an emergency situation. Communication is not optional in critical times, rely on equipment that ensures the best coverage.
