4G + 5G Multi-band DAS

SDM 1735-SB

There are many types of DAS system for in-building service that has been developed in various forms according to the demands of the market, multi-band has become popular as the network evolves from 4G to 5G NR.

This is a DAS system that supports 6 bands of 4G and 5G NR TDD simultaneously and has a structure that allows a total of 128 SUs to be distributed in a building. RF signals received from 5G NG gNB are converted into optic signals through MU and finally transmitted to SU via EU.
