The Cel-Fi GO is designed to boost data speeds and lift voice quality on your mobile phone when out in remote areas. This unit (authorised by Telstra for use on its mobile network) works with Telstra’s 4GX and Next G networks. The Cel-Fi GO is claimed to not interfere with mobile networks or other users when it is in use, which is different to a regular vehicle repeater. It does this via monitoring power levels of nearby cell towers and adjusting its own output to suit. Because the unit operates within a set frequency band, this also helps eliminate potential interference. The Cel-Fi GO offers up to 70dB of gain with boost coming on once the signal dips below -80dBm on the 3G network, or -96dBm on the 4G network). It also includes a WAVE (Bluetooth) app for iOS, Android and PCs.
