System debugging
a. Before switching on the power supply, please confirm the AC power input is standard
value again. Antenna cable and tri band repeater are well connected. Indoor antenna
keeps more 12 meters on horizon and vertical range with outdoor antenna.
b. Switch on the power to start the device, the red indicating light of power supply on the
panel lightening indicates the power has been connected and the repeater has begun
working.
c. Making outdoor antenna in position, now downlink indicating lights lighten or twinkle.
Otherwise, it can change outdoor antenna installation place or tilting angle of outdoor
antenna until downlink indicating lights lighten or twinkle.
d. Please install the indoor antenna in the central point of coverage area. And you go on
cellphone test at every corner of coverage area. According to the test results, please
optimize the mini repeater parameter installation place further and also the syestem
holding priority of up link signal indicating light lightens or twinkles. Right now, it means
that cell phone signal is well and it is able to communicate normally.
e. After finishing the installation, please make sure of spectrum analyzer or other measurement
devices to test relevant parameter whether it is met design requirements, especially to check
the VSWR, receiving and transmitting antenna isolation degree, downlink receiving
filed intensity etc. If the receiving filed strength is too weak,you can adjust the angle
and direction of the outdoor antenna. If receiving filed intensity is too strong, you can
consider adding fixed coaxial attenuator in BS communciation port or adjusting pitch
angle so as to lower the receiving electrical level. You also can do attenuation gain
adjustment to lower amplifying function from repeater.
Attention Items of Installation
a. Donor antenna should be installed away from the service antenna, at least 12m, and
the position where is 2m higher than the ground.
b. Service antenna is ceiling antenna which can be installed in ceiling and directed the
axis vertically to the ground. Please select the proper position to make the signals
distributed equally to every corner. If you choose directional flatpannel antenna install
in ceiling or wall, put antenna panel directly point to coverage area.
c. After all the RF cable has been installed, you should have an overall inspection to
prevent open-circuit and short-circuit. Because if the cable happens open-circuit or
shor-circuit. one part will not be able to work normally under slight damage conditions,
but it will destroy main device under worse conditions.
