Cel-Fi Systems are carrier-grade devices that are designed to eliminate in-building dead zones and work in harmony with the cellular macro network. Designed with smart antenna technology and onboard intelligence, Cel-Fi Systems continually seek out the best available signal and automatically adjust to any changes in the RF environment in order to maximize the signal gain to the user. Cel-Fi Systems are designed to protect the integrity of the wireless network while increasing the effective RF capacity of each base station. Cel-Fi Systems can more than triple the data rates experienced by wireless subscribers in their homes. Even the most non-technical subscriber can install a Cel-Fi System in a matter of minutes. No cables. No ladders. No drilling, No interference.
