Smart Digital-Analog Switch 
This repeater supports digital and analog modes. It can smartly select the right one based on the type of received signal, allowing you to enjoy digital delights with ease. 

Advanced TDMA Technology 
The application of Time Division Multiple Access (TDMA) technology greatly enhances spectrum efficiency, which allows twice the user compared with that of traditional FDMA. Obviously, this can not only save your cost in base station and frequency license, but also relieve the pressure of increasing shortage in spectrum resources. 

128-bit Digital Encryption 
 The advanced 128-bit encryption technology can secure your communication from being eavesdropped. 

Outstanding Heat Dissipation 
The unique cooling design combining a built-in heat pipe and a temperature-controlled fan ensures quick heat dissipation, enabling the repeater to work normally even with full power. 

Handy Management Service
With the management software, you can remotely monitor and diagnose a repeater. In addition, you can either record or play back the audio freely in digital mode. 

 Innovative LED Design
The innovative LED and the 2.0“ HD color display would deliver you the repeater status clearly, as well as a pleasing visual experience. 

 

Accessory Expansion
RD988supports third party to develop accessories expansion via front and rear port of the Repeater. This is achieved via the signal streaming and pin control through the repeater ports.

Repeater Diagnostic And Control (RDAC)
RD988 supports Remote (via IP port to connect to internet) and Local diagnostic (via USB) PC applications to monitor, diagnose and control the repeater status, thus increasing the maintenance efficiency. Hytera’s developed RDAC is able to support multiple master network connection to allow radio administrator to monitor multiple radio network upcoming!

 

Dual Slot digital audio streaming
RD988 supports streaming of both the voice slots via the rear port accessory pins, allowing third party for capability expansion.

 

Analog Digital Autoswitch
RD988 supports Analog and Digital channel auto switching, allowing efficient frequency sharing between Analog and Digital users during the digital migration.


IP Multi-site Connect
RD988 supports network interconnect via the IP port of repeater to form a private radio network, allowing wide area coverage to meet dispersed locations data and voice communications.

 

50W high power
RD988 supports maximum repeating power of 50W, and thus increasing the system coverage with lesser setup equipments.

 

16 channels
RD988 supports maximum of 16 channels, allowing efficient radio network control at different scenarios. The channel change can be performed either via RDAC PC tools, via the repeater's front panels channel knob and via the channel steering from the repeater's rear port.

 

Analog/Digital Operating mode
RD988  supports operating mode of Analog and Digital.

 

Analog/Digital back to back interconnect
RD988 supports different operating mode of Analog and Digital to interconnect for voice cross patch, allowing Analog users to communicate to the Digital users and vice versa. This has allowed the smooth migration for Analog users to the digital world!

 

Analog Repeater Knockdown
RD988  supports repeater knockdown, that when activated via the repeater's rear accessory pin, will disabled the transmit path of the repeater.

 

Multi-tone Decode
RD988  supports decoding up to maximum of 16 CDCSS/CTCSS in Analog channels, allowing repeating of different Analog voice users from various groups.

 

Analog Scan
RD988  supports Analog voice and signaling scan, allowing repeating of different Analog voice users from various groups.

 

Repeater Access Management
RD988 supports radio users access control to the repeater, allows better security to prevent un-authorized users from accessing the radio network.

 

Analog/Digital Telephone Interconnect (via DTMF signaling)
RD988G supports simplex voice communications between radio and telephone users. It allows a radio user to make a telephone call; or a telephone user to make either a Group or Private call to radio users. This feature utilizes the Commercial Off The Shelf (COTS) Analog Phone Patch boxes and a Plain Old Telephone Service (POTS) line to connect the Repeater to the Corporate Office Phone System (PBX) or Public Switched Telephone Network (PSTN).

 

Continuous Wave Identification (CWID)
RD988 supports Analog transmission of the repeater identification in Morse code format.
