Cel-Fi Go Series REVIEW

[@flynx42]

Nice video David, thanks. Is it also true that the connection between the cellular device and tower is negotiated, so by using a "booster" the tower will see a stronger signal coming from you and potentially reduce its transmit power?

[@RFShop]

Thanks for the remark :) Yes, it's a smart repeater so there is network control involved. I'm not an expert on that side of it but you will be more efficient than just boosting power for the sake of boosting power.

Hi David, thanks - very informative. Could you please advise how a Teltonika router using Wi-Fi calling compares to an R41 for voice performance for rural/remote area travel by 4WD? The R41 seems expensive for limited capability. Many thanks in advance.

Hi Richard, to be honest I’ve had WiFi calling work perfectly fine for me on the Teltonika’s.

@@RFShop Thanks David, any antenna suggestions for bullbar mounting or do I need to go roof-mounted?

[@RFShop]

For Cel-Fi I think bullbar is good. For 2x2 modems I’d go roof mount

[@flynx42]

I am using roof-mounted EPNT-4 antennas on my teltonikas and they work great.

please translate that '100dB' Gain into 'mili-watt' unit?

[@RFShop]

Hi. The problem is that the 100dB is only a relative value. It means that you can get 100dB more signal than without the Cel-Fi. However, it is more tricky than that as well. 100dB is a combination of what the unit does in the uplink and the downlink, and also a combination on the output and input of the Cel-Fi.
