3G / 4G / LTE Mobile Phone Signal Boosters

Do you struggle to maintain a mobile phone signal in your home or office? Does your mobile phone line break up during an important phone call?

There is an OFCOM approved solution to boost poor mobile signal strength at home, the office, industry and enterprise. Cel-Fi’s mobile phone signal booster strengthens indoor signal by up to four times, providing clear voice conversations and greater data throughout – there’s no need to restrict mobile conversations to outside. Cel-Fi mobile signal boosters are available in PRIME for small homes, SOLO for larger residential properties and commercial properties, GO M for vehicles, GO X for indoor/outdoor industrial and QUATRA for medium to large enterprises. Cel-Fi UK offers legal mobile phone signal boosters for 3G, 4G and LTE voice and data for all UK mobile networks: O2, Vodafone, Three and EE (and all virtual network operators, e.g. BT, Giffgaff, Virgin Mobile, Sky Mobile etc.). Cel-Fi is designed and produced by Nextivity.

How it works

  • The fully wireless system works by placing the Network Unit in an area of the building with the strongest signal (normally on a window sill).
  • It takes this signal, as little as 1 bar, and amplifies it to up to 5 bars.
  • The Coverage Unit is then placed in an area of the building with poor reception and works to create a bubble of stronger signal distributed across approximately 13,000 sq ft.
  • The system works wirelessly with all phones that operate with 3G or 4G signal – there is no need for an internet connection or to pair your device with the Cel-Fi unit.
