2.3.5 Channel filter
FirstNet band can be configured by either single 10MHz LTE or 2 contiguous 5MHz LTE bands, and one of the
channels can be turned off.
Up to 32 non-contiguous narrow band channels can be selected for both PS700/PS800 band, and each channels
can be turned on/off by WEB GUI.
Both wideband and narrow band channels have been designed based on 3GPP and FCC regulation.
2.3.6 Spectrum analyzing
Spectrum display function is so useful usually for commissioning, or when troubleshooting is necessary due to
the wireless complexity around the site where PSR is installed.
Spectrum displaying can cover the range of ;
 DL input / DL output & UL input / UL output separately or at the same time
 FirstNet/ PS700/ PS800 separately or full span of PSR band at the same time
2.3.7 External backup battery monitoring
The charging voltage of a lithium-ion battery must be controlled very precisely, and it is essential to continuously
monitor the voltage, current, and residual amount of the battery. Battery system consists of 3 or 6 pieces of
battery modules, and each modules supports BMS(Battery Management System) that enables to monitor the
current status of the whole battery system.
BMS offers the features regarding battery management ;
 Charging status (Fully discharged/ Charging with percentage / Fully charged)
 Available battery capacity
 Residual number of charging
 Charging voltage and current
