CEL-FI GO Smart Signal Repeater
Your mobile solution to improve 3G/4G voice and data coverage



Good things do come in small packages.

Cel-Fi GO is a 3G/4G mobile signal amplifer that provides up to 70 dB of signal gain -30x more powerful than a standard antenna/cradle set-up. All the while unconditionally protecting the mobile network



Provides Coverage For Automotive Application

Simply install Cel-Fi GO inside your vehicle and enjoy having great 3G or 4G mobile reception. No longer will you need to stop or drive to a particular spot to be able to make and receive phone calls. Your Cel-Fi GO can be configured to improve the mobile coverage for all types of vehicles from cars to trucks, to farm machinery and caravans, all with only a change in antenna


Increases Mobile Data Speeds

Slow internet speeds on your mobile device are often caused by low signal. If you suffer from low signal on the go, you will be able to relate to the frustration of trying to access email or the internet. Cel-Fi GO will amplify the available LTE or HSPA mobile signal and increase your data speeds dramatically. Email, internet, video and social networking speeds can achieve up to 4x improvement. Note: The 4G/LTE bands can only be utilised for data (not calls) unless both the smart phone and the local network support Voice over LTE (VoLTE).

Extends Mobile Phone Battery Life

Mobile phones use a lot more energy when in poor signal areas. The phone adjusts its output power to compensate in an attempt to boost the poor signal. As a result the phone will consume a lot more battery power. Using Cel-Fi GO, your indoor mobile signal should be high and the battery will last noticeably longer for you to work and talk while on the move

Eliminates Dropped or Missed Calls

Never miss or lose an important call while on the move because of coverage issues again. Cel-Fi GO will provide improved coverage in your vehicle so you can be
contacted when required. No longer do you have to put up with calls dropping out or terminating during conversation while on the move.

Improves Voice Quality    

The quality of a voice call is usually determined by the phone’s signal strength and nearby interference. With improved signal strength inside your vehicle, Cel-Fi GO mobile version will provide crystal clear voice quality for your cell phones.
