In-Building Communication When You Need It Most

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

FirstNet is a new network being rolled out for Public Safety Communication Devices. This high-speed, nationwide wireless broadband network will have dedicated bands for public safety agencies and first responders. Legacy equipment does not support FirstNet dedicated band.

Remote Communication Kits are a standard tool for Public Safety Equipment, as not all areas have good Cellular. Cel-Fi GO RED can be delivered as the core of a FirstNet portable communication solution.

Buildings of 30,000 Square Feet and above may require Public Safety Equipment, across 8 million US buildings. Cel-Fi GO RED can work alongside existing equipment that works with legacy devices, so that FirstNet service is available at transition.
