The Cel-Fi Story

Several years ago, we started Cel-Fi because we were really frustrated at the lack of indoor mobile network coverage, and thought it was time to do something about it.

We realised that a completely new signal booster was needed and felt we could bring a better product to the market than traditional analogue-based signal boosters by creating a fully digital solution. A team of some of the industry’s best minds was assembled to work alongside operators to define a new concept.

Fast forward to today, Cel-Fi offer the all-digital, high tech mobile booster that we once dreamed of. Its performance keeps surprising us, so much in fact that even the network operators have adopted it. We've understood consumer needs for a legal mobile signal repeater and have strived to develop smart signal boosters that are accepted by UK regulators. We are proud to be the leading developer of indoor coverage technology and have worked hard to develop the third generation Cel-Fi signal booster.

Along the way, we have built a significant patent-pending technology portfolio and have leveraged advanced signal processing and intelligent antenna design to create a new market for self-configuring, environmentally aware indoor coverage systems.
