Cel-Fi Mobile Signal Boosters for Business
Fix weak mobile signal inside your office, warehouse or vehicle. We survey, supply, install and support Cel-Fi signal boosters that bring clearer calls and better data indoors.
Why mobile signal drops indoors
Thick walls, metal roofs, tinted glass and distance from the tower weaken mobile signal inside buildings and vehicles. A signal booster picks up the outdoor signal, strengthens it and re-broadcasts it inside.
Cel-Fi boosters are made to work with the mobile network, with options for a single carrier and for larger sites where several carriers are needed.
We survey your signal, recommend the right system, install it and check it performs.

Cel-Fi questions
Plain answers about signal boosters.
What is a Cel-Fi signal booster?
It is a smart mobile signal booster that picks up an outdoor mobile signal, amplifies it and re-broadcasts it inside a building or vehicle.
Does a booster work for every carrier?
Different models support different carriers. We recommend the right model, or a multi-carrier solution, for the phones your team uses.
Will it help if there is no signal outside?
A booster needs some outdoor signal to amplify. We survey the site first and tell you if it will work.
Can I use a booster in a vehicle?
Yes. Vehicle boosters keep drivers and crews connected on the road and at remote work sites.
Are signal boosters legal to use?
Yes, when you use approved equipment that is installed correctly. We supply and install compliant systems.
