How do the Signal Boosters WorkThis article applies to Plug-n-Play units (Cel-Fi PRIME, Cel-Fi DUO, Cel-Fi PRO). Please read the relevant product pages for boosters that require installation like Cel-Fi GO X.
The Cel-Fi mobile phone Signal Boosters are legal to use and extremely easy to install:
- The fully wireless system works by placing the Window 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 a reasonable distance apart (normally in the centre of the building) and works to create a bubble of stronger signal distributed across approximately 13,000 sq ft. (for the DUO and PRO models) or 1-2 rooms (for the PRIME model)
- 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.
|Differences of gain||Cel-Fi signal booster||Traditional analogue booster|
|Gains in dB||100dB (or 1,000 times the most powerful conventional boosters (70dB))||Most boosters: 60dB. The more expensive boosters provide up to 70dB, or 1,000 less gain than Cel-Fi|
|Coverage||Up to 13,000 sqft||Most boosters: 3,000 to 6,500 sqft. The more expensive boosters that provide up to 10,000 sqft need complex indoor antenna installation.|
