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



Good things do come in small packages.

Nextivity’s Cel-Fi GO is a cabled 3G/4G mobile signal amplifer that provides up to 100 dB of signal gain – 30x more powerful than antenna options. All the while unconditionally protecting the mobile network.



Provides Coverage For Custom Application

Cel-Fi GO Stationary version is more flexible for advanced installations. It is ideal for high 5Ghz areas and those venues where you need a cabled solution to ensure great 3G/4G mobile reception. No longer will you need to move to a particular spot to be able to make and receive phone calls. Your Cel-Fi GO Stationary version can be configured to improve the mobile coverage for many types of applications from dongas to caravans, small marine vessels to school demountables.


Increases Mobile Data Speeds

Slow internet speeds on your mobile phone are often caused by low signal. If you suffer from low signal, 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/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 power output 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.

Eliminates Dropped or Missed Calls

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

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 building, the Cel-Fi GO stationary version will provide crystal clear voice quality for your cell phones.
