Phone repeater for mobile and home

While Kondinin Group engineers saddle up to test mobile phones again early in 2017, among the dozen or so handsets, they will also be taking with them a newly released carrier-approved repeater designed specifically for cars.

The Cel-Fi Go is available in two specifications; for vehicles and for stationary applications including homes or sheds.

To maximise coverage when driving in regional areas prior to the introduction of the Cel-Fi Go, a hard-wired patch lead from an antenna to the handset was required. Usually this was housed in a dedicated car-kit cradle or a passive connection cradle which are made specifically for each handset.

Hard-wired connections are always best, but most mobile phone handsets no longer support patch-lead ports. Passive connections also work, but are not always successful or efficient with the additional signal strength gained using the antenna. 

Typically losses in signal strength of around 3dB of gain are usually experienced through a passive connection. The CelFi Go will effectively provide all passengers in the vehicle with a boosted 3G and 4G signal regardless of handset make and model.

Plugged into an external antenna, the 12-volt powered unit uses a secondary antenna mounted inside the vehicle cabin to distribute the repeated signal. But connectivity doesn’t come cheap, expect to pay around $1,000 for a CelFi Go mobile unit (excluding antenna) with the stationary unit costing a little more at around $1,100 including GST.
