In the practical application, some repeaters are too weak for large indoor coverage. Very high power repeaters are expensive.
Trunk amplifier is also a special repeater with 20dB gain both link and 20dBm output power in downlink.
In some site, we could add one or more trunk amplifiers in one project link to achieve a quite large coverage.
Each line amplifier will provide an additional 20dBm power level, enough to cover between 1000~3000 square meters.
And if the capacity of donor signals are sufficient, more than 20 trunk amplifiers can be deployed, thus a quite large coverage can be achieved.
In some special solution, the cable maybe runs too long and it will loss much signal. We could add a trunk amplifier into the main cable line to boost the signals again.
