Product Description
DS-9300 Digital Repeater ("DS-9300") is the new generation of repeater developed by Hytera. Using
optical fibers to transmit signal, DS-9300 effectively makes up for the signal decline between base stations
(BSs) and radios.
Featuring low transmission loss and easy wiring, DS-9300 delivers long distance transmission of
multicarrier signals and strong and dynamic signal coverage. It is an ideal solution to blind zones such as
populated urban areas, large exhibition halls, stadiums, campuses, tunnels, metro stations and etc.
DS-9300 has two types of configurations, including low configuration and high configuration, which have
the same appearance but different features.


Flexible monitoring
DS-9300 provides remote monitoring (through IP network) and local monitoring (through RS232 serial
port). Users can manage all devices through the network management system, or remotely query,
configure and upgrade a single device.
 Excellent hardware performance
DS-9300 has low intermodulation noise, strong out-of-band rejection, low interference and great
interference resistance.
 Software-Defined Radio (SDR) Technology
DS-9300 achieves uplink squelch, delay compensation, carrier rejection, digital multi-carrier and etc
with the SDR Technology. It supports multiple network topologies such as star, chain, ring and hybrid
topologies.

