I agree that weBoost Connect 4g is not an a solution.
Most of booster design to have antennas on both sides. So
if you connect device directly to booster you broke them.
Exist amplifiers that are design to be connected to IOT/M2M device directly. For example
It is design to connect directly IOT/M2M. But it is design for US market. US marked use 3G/4G bands diffs from EU has.
I can’t install IOT/M2M device near antennas.
Currently device are 12meters far from Antennas. So I loose a lot off antennas gain.
For better maintenance tasks I must move device to another location, so I receive additional 12meters of cable.
So my us case is Antenna <12mCable> amplifier <12mCable><1:2 splitter>PepLink
if amplifier have gain +15dBi I never oversubscribe input of Peplink.
In case Antenna <12mCable><1:2 splitter>PepLink maximum signal I see was -40dBm…
with +15dB I will have -25dBm, I don’t think that I broke device in even in this case.
