2.1.11.1 Functions and features
- Programmable sectorization can be supported by using H-STM-8x4.
- Based on programmed sector definition, DL output signals received from H-FEM are combined by each
sector and transferred to H-DTM, or H-HOM.
- Based on programmed sector definition, received UL signals from H-DTM, or H-HOM are distributed and
transferred to H-FEM.
- For each sector, controls Power Ratio for multiple H-FEM with same frequency band to share DL output
power at Remote Unit
- ALC function for DL/UL Path
- To minimize negative effects by unused input/output ports such as the degradation of VSWR or isolation
between ports, the unused ports can be switched into 50 ohm termination by user.
- When any one sector consists of remote unit less than 4, H-STM-8x4 can be connected to H-HOM-L directly
without H-DTM.
 In this case, the attenuator in the common path of H-STM-8x8 should add 15dB attenuation using web
based GUI to compensate the loss of H-DTM.
