Deskripsi ] Repeater Digital Hytera RD-988

Repeater Digital Hytera RD988 adalah Repeater Hytera yang dapat diupgrade dengan mode ganda 50W, DMR (Digital Mobile Radio) dan Analog yang dapat bekerja dalam mode konvensional analog dan DMR. Repeater RD988 Hytera dapat ditingkatkan ke mode trunking atau simulcast oleh perangkat lunak saja. Paket upgrade satu langkah memudahkan pengoperasian dalam mode yang berbeda, analog konvensional, MPT-1327, DMR konvensional, trunking DMR dan siaran DMR hanya dengan satu platform perangkat keras.

 

Digital Repeater Hytera RD988 mendukung Remote (melalui port IP untuk terhubung ke internet) dan aplikasi PC diagnostik lokal (via USB) untuk memantau, mendiagnosis, dan mengontrol status repeater, sehingga meningkatkan efisiensi perawatan. Hytera yang dikembangkan RDAC mampu mendukung beberapa koneksi jaringan master untuk memungkinkan administrator radio memonitor beberapa jaringan radio yang akan datang.

 

Analog Digital Auto switch

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

 

Analog/Digital Back-to-Back Interconnect

Digital Repeater Hytera 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!

 

Dual Slot Digital Audio Streaming

Digital Repeater Hytera RD988 supports streaming of both the voice slots via the rear port accessory pins, allowing third party for capability expansion.

 

IP Multi-site Connection

Digital Repeater Hytera RD988 supports network interconnection via the IP port of repeater to form a private radio network, allowing wide area coverage to meet dispersed locations data and voice communications.

 

Analog/Digital Telephone Interconnect (via DTMF signaling)

Digital Repeater Hytera RD988 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.

 

Analog Scan

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

 

Multi CTCSS/CDCSS Decode

Digital Repeater Hytera RD988 supports decoding up to maximum of 16 CDCSS/ CTCSS in Analog channels, allowing repeating of different Analog voice users from various groups.

 

Upgrade to DMR Trunking Transceiver

DMR trunking Lite 2 carrier BS, including Power Distribution Unit, 2 Transceivers (Digital Repeater Hytera RD988) & Transceiver Power Supply, Switch, BS PSU, Base Station Controller, 2-channel RF System.

 

Open Standard

DMR Trunking Lite is based on DMR tier III standard, defined by ETSI in 2005, which is a digital radio standard for professional radio users. With dedicated control channel, DMR Trunking Lite can achieve versatile functions.

 

Smooth Migration

DMR Trunking Lite transceiver supports smooth migration from analog to digital, from conventional to trunking. Multi-modes provide you different choices for continual investment.

 

Integrated RF System

Intergrated 2-carrier RF system, significantly reduces the space and cost for divider, combiner and duplexer.

 

Non-centralilzed Structure Design

Non-centralized structure is only used for less than 5 base stations. It will ensure a cost-effective and flexible networking especially suits for small scale of network.

 

Upgrade to DMR Simulcast Transceiver

DMR Simulcast Single Carrier BS, including Built-in Router, Synchronized Expansion Unit, Transceiver (Digital Repeater Hytera RD988) & Power Unit & Duplexer.

 

Smooth Roaming and Handover

In simulcast system, the radio is capable of roaming and handover seamlessly between different BSs , the ongoing communication can continue normally during handover.

 

Dynamic Voting

Simulcast system can provide good voice performance in overlap area as radios in overlap area can always receive the best voice frame through dynamic voting. As a voting center, MSO is used to analyze each voice frame received from Base Stations in real time. The best voice frame will be extracted and sent to radios.

 

Analog/Digital Self-adaptive

Simulcast Base Station channels support working both in analog and digital mode, to ensure smooth migration from analog to digital network. Digital or analog mode is automatically selected based on the incoming signals.

 

Smart Subnetting and Patching

According to management requirements, DMR simulcast system can be divided into different subnets by Base Station or by time slot of channel unit in each Base Station. Each subnet can work as a independent simulcast system. Different subnets can be patched to make a larger subnet temporarily according to the requirements.
