1.2 Hytera HRT X1p

Our "I-Phone" among the end-user units for digital voice communication is targeting to those, who are in essential need of a covered bearing in conjunction with a full functionality and usability. It already includes the options "mandown" and "GPS" and provides the same durability as the HRT PD-785. The highlight is the flat construction of the corpus with dimensions, which only one can find at smartphones. Therefore the user may bear it concealed under a jacket or a suit.

X1P

General Features:

Dust- and Waterproof to IP67
The X1p is reliable even in harsh operating conditions. It is waterproof and dustproof in accordance with degree of protection IP67, which means it is capable of withstanding a water depth of one meter for at least half an hour. The X1p also meets the requirements of the American MIL - STD - 810 C / D / E / F / G  standards and can therefore withstand even extreme mechanical loads

Versatile Features                                                                       The X1p providing complete data services and features e.g. text message, status reports, distress calls, mandown alerting (G version), loneworker, roaming, voice encryption, transmission of position data, many analog signalling protocols (5-tone, MDC-1200, PL, DPL)

Integrated GPS as Standard
With the aid of the integrated GPS module the X1p can send position information to dispatcher systems, for example. Dispatchers can evaluate this information and use functions such as geofencing, radio localization and GPS tracking. The X1p can also determine and display the distance and direction to other radios with GPS support in the DMR system.

Supports Hytera BT Headsets
 Wireless audio accessories from Hytera can be connected directly to the X1p. As such the radio can be carried conveniently without having to route cables through the clothing.

Different Digital and Analog Operating Modes
The X1p was developed in compliance with the ETSI Digital Mobile Radio (DMR) standard. It supports both conventional DMR operation (DMR Tier II), DMR trunking (DMR Tier III).  The X1p can also be operated in analog mode. Along with conventional analog radio it also supports analog trunking as per MPT 1327.

Calls to the Telephone Network
Provided the X1p is registered in a DMR Tier II system via a repeater, selective calls can be made from the radio directly to the telephone network via this repeater. Telephone subscribers can also call specific individual radios or also groups.

Upgradeable Firmware
Upgradeable software makes new features possible. By altering the firmware-software, other digital and analog operating modes can be enabled without the need for purchasing a new radio device.

Multiple Languages
The X1p supports various menu languages. T9 support for text entry is available.

Large Color Display
The X1p has a 1.8" TFT LCD display (65,536 colors) that can be clearly seen even in bright sunlight outdoors.

Digital Voice Encryption
Encryption with encryption algorithm ARC4 (40 bit) in accordance with DMRA or with optional algorithms AES128 and AES256 (128 and 256 bit) ensures secure communication.

Additional Operating Time
In comparison to an analog radio, the operating time can be significantly increased by using DMR TDMA. This means that an operating time of up to 10 hours is possible.

Direct Mode (DMO)
Like all Hytera DMR radios, the X1p supports the usage of both timeslots in the direct mode (DMO). In this way two calls can be made at the same time in the same area.

3. Digital Voice - Basise Station Transceivers/Repeater Stations (BTS/mBTS)

The base transceiver stations (BTS) or repeaters are representing the network/system infrastructure and with that are being an integral part of a digital radio network. The network infrastructure ascertains the radio coverage within larger regions, different territories located apart of each other or within larger, complex buildings, whereas it makes no difference, in which part of the globe a BTS is being installed.

The connection of the BTS among each other will be done by the so called "IP-Site-Connect" which makes use of an IP-basing network connection. In this way the user gets the opportunity to talk with another subscriber, who is located in a distant region (e.g. another city) or to talk with a remote long distance operation center (LDOC).

Certainly there is also a remote control and diagnostic tool for a BTS, which offers a complete overview of the most important parameters of it. In order to do that, a technically trained person will use a special software (RDAC) on his service notebook and check into the system, where also alterations within the radio network can be done.       In case of any malfunctions, the RDAC will omit a technical alert, that actions can be taken with immediate effect.
The PC-based application can be used to monitor, inspect and control the RD625. The software supports network access from multiple points and allows administrators to monitor the DMR radio network all the time.

All Hytera base stations having the opportunity, to be connected to VoIP phone switches, in order to provide a radio subscriber a link into the public telephone network. In such a way a radio subscriber may perform a telephone call to phone subscriber and vice versa.  Phone calls can be done as single/private call or group call within a certain talkgroup (TG)

The network may be secured against unauthorized use, also authorized subscribers may be limited to use only certain BTS in regional areas or establishing connections to a limited number of groups or call types.

For different types of deployments there are different BTS, which we want to introduce you in further.

 

3.1 Hytera BTS RD-985/985S

With 50 Watts output power, the BTS RD-985/RD-985S are the leading edge. They are predistined to provide radio coverage within larger regions and as well for in-building/in-house coverage within larger, complex facilities or where several antennas and combiners shall be used.

The RD-985 supports radio networks accordingly to Tier-II (RMO), whereas RD-985S is also supporting trunking networks accordingly to Tier-III or XPT (TMO) and in analog networks it may also support sumulcast operation.

Both BTS are made as 19" rack device and can be easily integrated into installation rooms or into 19" racks.

 

RD-985

 

rd985 rear


General Features:

Dual Mode and Automatic Change of Operation Mode
The RD985/985S can be operated both in analog and in digital mode and is completely compatible with the analog systems currently in use. The device can automatically change between digital and analog mode depending on the type of receiver signal and, thanks to the elimination of manually configuring frequencies and channels, both time and money are saved.

100% Efficiency
The BTS offers constant power (up to 50 watts) and therefore meets the high requirements of all conventional digital radio systems.

Flexible Installation Options
The BTS can be installed in a 19-inch equipment rack using an optional installation kit. Alternatively, you can easily install it on a rack, a mounting support or a work table. Thanks to the space intended for an optional duplexer inside the device, the device remains compact.

Efficiency in the VHF/UHF Range
Thanks to the TDMA technology, twice as many users can use the same channel, such as is the case with analog or digital FDMA systems. Due to the restricted frequency resources, this represents an important relief and reduces the expenses for system terminals and frequency licenses.

Secure communication
The RD985 repeater features an enhanced digital encryption function that protects your communication against enemy (or friendly) eavesdropping or monitoring.

High cooling capacity
Thanks to heat dissipation, the power amplifier can dissipate its heat exceptionally efficiently. In addition, the integrated fan system ensures stable and powerful operation.

Operation in Unmanned or Operator Mode
If the base station is operated on an analog channel, you can choose between operator or unmanned mode. In operator mode the base station can be used as a duplex transceiver.

High reliability
Since the repeater was designed according to military standards, it offers high reliability and excellent performance. Test results from independent laboratories have shown that the device can be operated for up to 100,000 hours without interference and it therefore meets the requirements for use in extreme situations. 

High Resolution 2"-LCD-Color Display 
Whether during regular operation or an ongoing maintenance: The large LCD color display will offer all relevant information.  

Professional Design 
The innovative illumination on the voloume knob provides additional usability. Thanks to the well designed menu and the large selection knob, the use of the BTS is very simplified.  

Informative LED-Display 
The 8 LED display on the front panel providing an easy identification of the current status.  

Ergonomic Design 
The slanted grips giving the opportunity of an easy installation or transport of the BTS.

3.2 Hytera BTS RD-625

The base transceiver station RD-625 is an "allrounder" among the network components for digital radio networks. It is designed for either deployment, for regional coverage and for in-house installation within complex facilities, such as stadiums, shopping centers, airports. Due to the extreme small dimensions, the BTS may be easily and concealed integrated in existing house installations (e.g. on a wall inside a building or on the rooftop near the antenna). With its 25 Watts the BTS can provide a good coverage within a city. Although the dimensions are very small, a duplexer still can be integrated within the corpus of the BTS and furthermore, all the functionalities of digital radio networks accordingly to Tier-II will be supported.  

RD-625

General Features: 

Dual Mode and Automatic Change of Operation Mode
The BTS RD-625 repeater can be operated both in analog and in digital mode and is completely compatible with analog systems currently in use. The device can automatically change between digital and analog mode depending on the type of receiver signal, saving both time and money by eliminating the need to configure frequencies and channels manually.

Automatic AC/DC Switchover
The integrated power supply of the RD625 automatically chooses between alternating current and direct current. This makes it possible to provide a fail-safe radio signal by connecting the repeater to an independent source of direct current (UPS) in addition to the normal supply of power. If the AC supply fails, the RD625 switches to the second power supply automatically.

Easy Installation
The RD625's well-engineered design makes wall mounting easy using the optionally available wall bracket. This makes it possible to install the repeater flexibly and conveniently in buildings.

Compact Design
The RD-625 combines transmitter and receiver components, the voltage supply and the duplexer (optional) in its compact corpus.

3.3 Hytera mBTS RD-965 (Mobile Base Transceiver Station)

The RD-965 is a very special product in the landscape of Hytera system components, as it is a mobile and portable base transceiver station (mBTS), which is even suitable for outdoor deployments. The mBTS is completely waterproof and provides -with a powerful battery pack- an autonomous power source. Of course, it may also be operated with an ordinary power supply, which is connected with the DC power grid.

All optional parts may be put into the optional backpack.

The RD-965 is specially designed for temporaray deployments in uncovered mission areas, where there is no radio network infrastructure available, whether during a special event or due to devastation during a natural disaster like a flood or an earthquake.

Certainly the RD-965 also may be operated as an in-house coverage network component.

Even that the mBTS is very small in regard of its dimensions, it is a big gun in regard of its features! It contains everyting, what the larger sister products are providing, only the maximum output power is limited to 10 Watts, due to its special mission it has. 

RD-965

General Features:

GPS
The GPS module enables emergency control rooms to monitor the location of a small radio network in real time if the repeater is being used as a mobile unit.

Small Backup Battery (optional)
The 10 Ah lithium-ion battery can support at least eight hours of operation at a duty cycle of 50% and boasts a high transmitting power as an emergency power supply for outdoor operation and mobile use. RD965 is compatible with the SMBus 1.1 standard and can monitor battery statuses, such as the estimated remaining capacity. Intelligent charging management enables the battery to be charged automatically for later use. The three-stage battery protection enhances the safety and reliability of the charging process.

Repeater Diagnostics and Control System
Using a PC-based application, it is possible to monitor, diagnose, and control remote repeaters (via the IP interface with a network connected) and local repeaters (via USB port). Hytera's RDAC software supports network access at multiple points and enables the administrator to monitor two way radios registered in the DMR radio network.

Voice input/output via dual timeslots: ideal for monitoring and voice recording
The device supports voice input and output via dual timeslots in digital mode and enables users to continuously record conversations.

Flexible networking
By connecting geographically distributed repeaters that run at the same or different frequencies to form an IP-based and location-independent wireless communication network, mobile radios can use voice and data services even when in roaming mode. The RD965 can be used with the RD-985 in a repeater network.

Outdoor operation and IP67 degree of protection
RD-965 fully complies with the standards MIL-STD-810 C/D/E/F/G and conforms to the IP67 degree of protection, ensuring exceptional performance even in harsh conditions.

Slim and Portable
With its compact design, the device measures a mere 52 mm high and weighs less than 5 kg, including the 10 Ah battery.

16 Channels
The repeater supports up to 16 voice channels. The user can switch between channels using the PC-based RDAC software, the channel selector switch on the front panel of the device, or the external interface on the repeater.

Upgradeable Firmware
New functions can be integrated easily and smoothly using software upgrades, meaning the user does not need to buy a new device. 

Digital/Analog Connection
Using a back-to-back-connection between two repeaters, analog radio networks can be connected to the DMR radio system, facilitating the smooth transition from analog to digital radio technology. 

User-Friendly Control Panel
The control panel has various indicators for the channel status, a button for the channel settings and a connection for a hand microphone or a remote speaker microphone.

Flexible Applications
The repeater can be mounted on tables and walls to provide mobile radio coverage within a building, installed in a mobile case or rack for emergency communication, or carried on your back for outdoor use. The RD965 repeater is also suitable for providing tunnels and underground facilities, e.g. underground parking lots, with radio coverage.
