CEL-FI GO is a 3G/4G cellular signal amplifier that uses Nextivity's award winning technology to provide up to 100 dB of signal gain (1000x that of traditional boosters), while unconditionally protecting the Operator's network. CEL-FI GO has two options available: as a Mobile Kit that includes a 12V cigarette lighter style power adapter, or as a Stationary Kit that includes an AC Adapter. Once installed, CEL-FI GO intelligently and automatically senses and adapts to its environment — including Operator network changes, or those caused by other nearby CEL-FI devices or boosters
