Amplitec S33T series
digital mobile signal repeater is used to extend mobile providers' networks.
These repeater are cellular solutions
with easy installation, which enable operators to improve signal coverage
without establishing new BTS. The repeater is adjusted strictly to the
bandwidth at which mobile provider performs. It support 3 sub-bands and up to
12 channels per customer’s request. In case it’s necessary to change the band
frequency, the user can easily do it thanks to the SDR technology in the
digital repeater.
The repeater has Digital IF SAW filter technology. Support 3 sub-bands and each bandwidth
is with maximum 24MHz.
It can upgrade the
underlying FPGA code with the help of the upper software to change the
frequency-selecting and band-selecting mode, and it also can make a flexible
configuration to the parameters, such as the operation bandwidth and so on.
It can be controlled and
monitored, via RS232 connecting PC for local control, via GSM modem connecting
PC for remote control, set the frequency and ATT of UL or DL, check the output power
of UL or DL, and check the temperature alarm and ALC alarm via the OMT.
