Nextivity Cel-Fi RS2 3G Coverage Booster Review

Before we get straight into it, we had better explain that there are two units that come included. One is the window unit and obviously sits by the window, while the other is a coverage unit and should be placed at the opposite side of the building to give the very best boosted signal to your mobile device.

Lets start by taking a look at the window unit which is the larger of the two units and incorporates a stylish white design with a Nextivity logo upon the front. There is a small LED panel which shows how much signal the unit has picked up. Obviously you will want to attempt to get five bars but depending on your area, this may not always be possible. Once this has received the signal, it will output and boost the signal to the coverage unit, which we will look at shortly.

The whole unit is white, with a grey base, which features a rubber foot in each corner. Next to the feet, we can see that the unit can be mounted from the bottom, onto a wall with ordinary screws of the right size. The included power adapters plug into the bottom and there is a small button if needing to flash the unit.

Also on the bottom is space for the programming flash card, which simply inserts with ease, though from our use of this unit, we have had no need to install this.

The other unit is branded as the “coverage unit” and is simply for doing what it says on the tin. It gets the coverage directly from the window unit and outputs it to your building. The unit is a little bit smaller than the window unit and incorporates a slightly different design in terms of what is on the front. We find a panel with a diagram of a building which notifies you as to when it is in range or out of range. There is also a number digit display which goes from 0 to 9 to determine the best possible location. By utilising this, you can move the unit into the prime location to obtain the best possible signal and aim to get an 8 or 9 on the display.

The back of the unit has ventilation slats, much like the bottom of the window unit to allow any hot air to escape. In terms of operation, the units are both nigh on silent, but just requires that little bit of room to breathe.

The bottom of the unit has a connector for the included power adapter, a button for flashing the device and also a connector, which is also for use when flashing the device. As you can see from this angle, it’s quite a lot slimmer than the window unit.
