While down in the valley, I maintained 3 or more bars constantly with the Cel-Fi (in 3G mode), where people in other vehicles dropped down to 1 bar, often where it shows 1 bar of signal but would not make a call. Interestingly, following the completion of this test, I decided to drive down into a valley back towards Lithgow, following some of the guys from Unsealed 4X4 on a bit of a drive. Additionally, I’ve included the Telstra coverage maps for 3G and 4G in that area. We expressly had a switch installed to be able to turn the power to the Cel-Fi on and off, and I’d highly recommend this because it is useful if you want to leave it running with the car off, but also prevent it from draining the battery unnecessarily. I started in an area where I knew I would have reception, and then tested and recorded the signal with and without the Cel-Fi on. For that reason, I decided to drive to an area where I knew I would eventually lose reception, and then measure approximately every 500m the signal I could get with and without the Cel-Fi on. It was important to me to be scientific in my testing. To give you an idea of the amount of signal boost this provides, 100dB is 1000x stronger than the standard signal. We had the Trucker pack installed in the HQGU, which provides up to 100dB of gain. You also need to register the device with the carrier using a smartphone app. Note: The Cel-Fi is carrier specific, so you need to buy the one that is designed to connect to whichever mobile network you are using. Your phone obtains the boosted signal from the GO to improve voice and internet connectivity.
It works by receiving the network signal, amplifying it and then re-transmitting it within the vicinity of your vehicle.
Intrigued about the concept, we decided to put it to the test to see how well it worked.Ĭel-Fi GO is a mobile repeater station for your vehicle. If you haven’t heard about this thing, basically it is a mobile repeater, which can improve mobile reception in your vehicle. Recently, we got a Cel-Fi GO installed in the Mobile HQ GU.
