The Cel-Fi product line is the best solution on the market for addressing the universal challenge of poor cellular coverage in the office or at home. Unconditionally network safe, with an exceptional coverage footprint and Carrier approved for 3G/4G/LTE voice and data.

Cel-Fi GO X

The Cel-Fi GO X has a rugged design to withstand harsh conditions including dust and water exposure. Cel-Fi GO utilizes nanotechnology to produce a thin film coating across the entire PCB assembly. This coating, combined with an industrial design for harsh conditions, enables the device to support weather conditions that include water, dust, and dirt.

Cel-Fi Go can also be used to support new Push-to-Talk over Cellular (POC) radio systems where poor signal strength indoors inhibits the system.
