1.2 TETRA NETWORK OVERVIEW

A short overview of the TETRA radio communication system, adopted reference standards, network infrastructures and user terminals are reported in this chapter.

TETRA stands for TErrestrial Trunked RAdio (Trans European Trunked Radio). The TETRA standard relies on a thoroughly digital technology and it is able to offer services and performances not yet available on alternative technologies. By using TETRA Networks it is possible to obtain a greater data transmission rate thus more information can be sent in a shorter time. This means that you can send longer messages to all the TETRA terminal users or that a greater number of these can be served under the same system resources. A typical TETRA application is the management of a great number of mobile radio units involved in voice and data communications. In TETRA systems, Voice and Data transmission services are supported by a radio transmission interface which has the following main parameters:

• Channel spacing: 25 kHz or 12.5 kHz;

• Modulation: π/4 DQPSK;

• Gross channel rate: 36 kbits/s (25 kHz channels) or 18 kbits/s (12.5 kHz

channels);

• Access mode: TDMA with 4 timeslots (25 kHz) or with 2 timeslots (12.5 kHz);

• Transfer rate: 7.2 kbits/s per timeslot;

• Max transfer rate: 28.8 kbits/s (unsecured transmission);

• Transfer rate (secure transmission): up to 19.2 kbits/s.

An example of a TETRA system architecture is shown in Fig. 1.1. The main system elements are:

• Radio base stations (covering the whole network);

• Switching and control units;

• Network management system;

User terminals are divided in:

• Hand-held radio;

• Vehicular radio;

• Fixed station (desktop).

1.2.1 TETRA network equipment

In this paragraph the main characteristics of the TETRA radio communication system are briefly described (see Fig. 1.1). Both the infrastructure and the terminals are taken into consideration.

1.2.1.1 Radio Base Station (BS)

The Radio Base Station (BS) is a network element used to provide the electromagnetic coverage of a certain cell and the radio connection with the user terminals. Each base station is able to manage many RF carriers; each RF carrier manages four channels.

The radiating system of the Radio Base Station is suitably configured depending on the present requirements.

1.2.1.2 Switching and Control Node (SCN)

VS 2001

Technical Handbook

Accessories

Another element of the TETRA network is the Switching and Control Node (SCN). The system switching capacity are mainly concentrated in the SCN, which controls a certain number of Radio Base Stations, dispatch stations and even other SCNs.

Moreover, by using an ISI (Inter System Interface), the SCN can interface itself with other TETRA networks and other external networks (e.g. ISDN, PSTN, PABX etc..) through a gateway.

1.2.1.3 Network Management System (NMS)

The management of the TETRA network is accomplished by the NMS (Network Management System) which is implemented on a single dedicated station. The NMS can control a certain number of SCNs and can supervise the whole network system.

1.2.1.4 Control Room Server (CRS)

The Control Room Server (CRS) constitutes the interface between the TETRA system and the room operators. It manages a certain number of external working stations connected, for example, through a LAN (Local Area Network).

1.2.1.5 WDS, RDS and LDS

There are different types of dispatch stations:

• WDS;

• RDS;

• LDS.

P/N: 779-0373/02 Revision 02

The WDS is managed by an operator with a fixed terminal; the connection to the SCN is guaranteed by a WAN (Wide Area Network).

The RDS is the radio dispatch station and it is managed by an operator with a terminal; this time the connection to the system is carried out via radio.

Marconi Proprietary information

Page 5

VS 2001 Technical Handbook

General Information

The LDS is directly controlled by the room server and its connection is implemented through a LAN.

1.2.1.6 Terminals: fixed stations, vehicular and hand-held radios

Mobile stations are made up of vehicular and hand-held radio terminals. Both of them can handle concurrent voice and data transmissions and they can communicate each other relying on a base station or not.

Fixed stations are another kind of radio terminal with the same operative functions of mobile stations, but they are generally installed inside a radio room.

1.2.2 Reference standard

The standards, adopted as reference in the implementation of TETRA radio communication network, are the following:

• ETS 300 394-1

• EN 301 489-18

• ETS 300 392-2

• ETS 300 396-2

1.3 GENERAL CHARACTERISTICS

The VS 2001 equipment is a digital vehicular radio terminal designed in compliance with the TETRA standard.

The equipment comprises two main modules: the Radio Unit transceiver and the Front Panel.

The Radio Unit consists of a single piece, die-cast aluminium container that contains the boards with the circuitry for signal processing both in transmission and reception phase.

The Front Panel acts as an interface between the operator and the transceiver. The VS 2001 equipment is shown in Fig. 1.2. The Front Panel is installed on the

dashboard. The transceiver is installed in the boot (trunk) of the vehicle, up to 6 metres from the Front Panel.

1.3.1 E-WHERE/FPG1/A Module

For the localization of the vehicle VT in which the VT equipment is installed we can install also, the E-WHERE/FPG1/A interface.

The E-WHERE module (P/N 771-0940/01) is used in the vehicle configuration equipped with a GPS E-WHERE module.

The equipment by means of the interfacing with FPG1/A, allows the use of equipment like VT and VS (vehicle radio).

E-WHERE module make available the PEI serial line for a connection for PC on FPG1/A; it avoid possible conflict with the GPS equipment that also used, of default, the PEI serial line.

In the Fig. 1.3 the configuration is shown:

1.4 NETWORK APPLICATION

The equipment can be used in the following operating modalities:

Trunked Mode The Peripheral-Peripheral and Peripheral-Fixed connections take place through

the Network (Air Interface Protocol). Call Control manages the activation, maintenance and release of voice/data calls

and is capable of managing up to four calls simultaneously. The calls can be Individual or Group.

Direct Mode The Peripheral-Peripheral connection takes place directly. In this case the

Peripheral-Network connection is not possible unless supported by Gateway which constitutes the connecting element.

VS 2001

Technical Handbook

Accessories

Dual Watch Mode The radio unit shall support Dual Watch Mode and than it is able of operating both

in Trunked and Direct mode although not simultaneously. Dual Watch Mode enables the user to monitor the trunked mode control channel

while operating in Direct Mode and to monitor the channel in Direct Mode while operating in Trunked Mode. This allows the user to switch from one operating modality to another, but only when the radio is in IDLE status or when the call is not active.

- Trunked Mode

- Half-Duplex Mode;

- Full-Duplex Mode (Time Division).

- Direct Mode:

- Half-Duplex Mode.

The operating modality selection is carried out by the user.

• Selection and sending of voice call, with the possibility of selecting the priority.

The voice calls may be Individual or Group type;

• Voice and data communications management with:

- Mobile radios;

- Dispatcher stations;

- Public or internal network telephone users.

1.7 PROGRAMMING THE EQUIPMENT

The equipment operating parameters are normally programmed with the auxiliary of an external PC and a suitable programming kit (described in Section 4 of this handbook), letting the user the possibility, however, of entering and/or modifying some data by means of the Front Panel controls.

The configuration is accomplished by connecting the equipment to a personal computer in order to carry out all of the configuration (individual and network data) and personalisation operations.

For this purpose, a suitable software, the PRP (Programming Package) operating on Windows 95/98/2000 NT platform has to be loaded in the personal computer having a user friendly type of user interface with self explanatory windows. This program allows the personalising of the various radio units and to carry out the write, read, modify and print operations in the relative files.

In order to facilitate the above mentioned operations adequate aids are supplied such as:

• Instruction manuals for programming and installing the software.

• "Help" on the display regarding the intervals relative to the parameters to be

set.

VS 2001

Technical Handbook

Accessories

Protect the radio from sprinklings of water and/or other liquids and from dust.

Be careful not to damage the vehicular radio when cleaning the vehicle.

Do not use the vehicular radio if the antenna and/or the antenna cable are damaged.

The electronic devices are sensitive to electromagnetic interference (EMI) if not adequately shielded, designed or configured differently for electromagnetic fields immunity. If electromedical equipment (ex. pace-makers, acoustical equipment, etc.) is used together with the vehicular radio, make sure that it is adequately shielded from external electromagnetic fields.

P/N: 779-0373/02 Revision 02

Do not take the radio into environments that have a potentially explosive atmosphere (ex. fuel storage sites, filling stations, etc.).

The E-WHERE is only suitable for vehicles with the negative pole of the battery earthed to bodywork. Installation on other vehicles can cause faults and damage/fire to cables.

General Information

Install the vehicular radio following the instructions given in this manual. The equipment must be installed in such a way that it complies with the national regulations in effect.

Carry out the maintenance interventions on the vehicular radio following the instructions given in this manual.

Follow all accident prevention standards when carrying out maintenance interventions on the vehicular equipment and use the proper tools (spanners, screwdrivers,…..).

First and second maintenance level interventions, on the vehicular radio are to be carried out by authorized technicians only. Third maintenance level interventions are to be carried out by OTE technicians only.

Use only original accessories and spare parts, approved by the manufacturer, suitable for the vehicular radio. The use of different accessories and/or spare parts makes the safety and electromagnetic compatibility certifications to be valid no more and it could lower the user safety level and/or generate electromagnetic fields that exceed the accepted limits.

After the radio has been trasmitting for a long period, it may reach high temperatures: in such a case avoid touching the radio shell.

The emergency call is a priority type call. The vehicular radio, like all mobile telephony equipment, operates

with radio frequency signals, therefore, the forwarding of the call depends on the network coverage at the moment of the call.

If you need send an emergency call, keep pressed the emergency button for at least 2 seconds.

The radio complies with all product specifications and great care is taken by the manufacturer so that user safety, as far as the effects of electromagnetic waves on health are concerned, is guaranteed within the limits established by the international specifications.

Accessories

The individual circuits of the Base Band section can be summarised as follows:

• A microcontroller that has the general control of all the radio activities. It is

supported by a RAM, a FLASH EPROM, 2 EEPROMs and an identification code generator;

• Microcontroller interfaces to the FPGA and directly to the R/T card (this

section is included in the microprocessor block);

• A DSP (with its own RAM) which is interfaced to the A/D and D/A converters

of RX and TX and to the audio signals (from microphone/handset and to loudspeaker/headset) through the CODEC;

• An FPGA which acts as a control interface for the R/T card and as an

interface between the DSP and the A/D and D/A converters of the R/T section. The FPGA also generates all the timing signals. All the timing signals are derived from a reference clock, set at Fref (see Tab. 2.5), and generated by an appropriate circuitry.

Since some parts of the Base Band card are powered at 5 V and some others at

3.3 V, there is a level Translator circuit in order to connect them. Other electronic devices contained on this card are listed as follows:

• Protection diode against power supply polarity inversion;

• LC filtering of battery power supply;

• Main FET switch which interrupts power supply to all equipment circuits;

• Audio power amplifier to drive the loudspeaker;

• Stabiliser generating a voltage of +7.2 V used by the R/T card;

• Stabiliser generating a voltage of +5 V used by the Base Band card;

• Stabiliser generating a voltage of +3.3 V used by the Base Band card;

• Stabiliser generating a voltage of +5 V (+5VTLC) used by the Front Panel.

Connection to the R/T card is carried out via the J02 double 36-pin connector (see

2.3.1.2). Connection with the P.A. card is carried out via the J04 6-pin single comb male

connector (see 2.3.1.2).

2.3.1.1 External connector

The P01 external connector (25-pin male D-type connector) provides the physical interface between the Base Band card and the external accessories.

The signals, exchanged via this interface, are:

• User commands (i.e. terminal turning on command, Push-To-Talk (PTT)

command, alarm command)

• Data with terminal on asynchronous serial line with the possibility of using the

RTS and CTS control signals. The baud rate can be selected at 110, 300, 600, 1200, 2400, 4800, 9600, 14400, 19200, 28800, 38400, 57600 and 115200 bps;

• Data with terminal on a second asynchronous serial line. The baud rate can

be selected at 9600, 19200, 38400 and 57600 bps;

Technical Description

2.3.1.3 Level Translator

The level Translator is the interface for the 3.3 V signals generated on the Base Band card and addressed to the 5 V CMOS devices located on the R/T card.

Such signals are the following:

• Signals connected to R/T card and generated by the Time Base unit. Their

voltage level is translated from 3.3 V to 5 V.

• Signals of the serial synchronous interface and signals necessary for the DAC

programming. Their level is translated from 3.3 V to 5 V.

• Configuration signals (R/T and P.A. cards) for the transmission and reception

processes. The above mentioned signals are generated by the Time Base and then converted from 3.3 V to 5 V.

2.3.1.4 Power Unit

This unit provides the power supply voltages for the Base Band card, the R/T card, the P.A. card and the connected peripherals. The power supply voltages provided by the power unit are derived from the vehicular battery.

The following power supply voltages are available:

• VBATT+: general power supply voltage provided by vehicular battery (12 V

nominal);

• VBATTINT: general power supply voltage interrupted by dual MOSFET (12 V

nominal less losses on MOSFET and protection circuitry);

• +8 V: power supply voltage dedicated to R/T card (7.2 V nominal);

• VMASTER: power supply voltage adjusted to approx. 6.5 V;

• 12 VTLC: power supply voltage dedicated to the remote control;

• VD5: 5 V for 5 V digital circuitry;

• VCC: 3.3 V for 3.3 V digital logic;

• VA3: 3.3 V for 3.3 V analogue circuitry;

• VC2: 2.5 V for DSP core.

2.3.1.5 I/F Audio

This unit provides the interface between the external audio devices (loudspeaker/ headset and microphone/handset) and the Digital Signal Processor device (DSP), both in transmission phase (towards the loudspeaker/headset) and in reception phase (from the microphone/handset).

The input main/rear microphone signal is approx. 200 mVrms. The Audio interface provides the signal voltage level (2.5 Vpp) required by the CODEC voice digitalisation device that samples the signal at 8 kHz on 13 significant bits. It supplies the digitised value to the DSP on a dedicated DXS synchronous serial line, with timings generated by the Time Base unit.

Page 30 Marconi Proprietary information

P/N: 779-0373/02

Revision 02

In the transmission phase the DSP generates the voice samples at 8 kHz towards the CODEC; the samples are digitised on 13 significant bits and transmitted on a dedicated DRS synchronous serial line with timings generated by the Time Base. The CODEC reconstructs the audio analogue signal and supplies it to the audio amplifier which reconditions it in power (8W max. in 4 Ohm, 125 mW max. in 25 Ohm) as a function of the signals coming from the micro.

The I/F AUDIO block is controlled in stand-by by the microcontroller.

2.3.1.6 Microcontroller

The microcontroller manages all the network digital processes and the internal activities of the VS 2001 equipment. The processes managed by the microcontroller may be resumed as follows:

• TETRA protocol management from the Upper MAC sub-level up to the

Mobility Management and Call Control upper levels;

• Co-management with control unit present on management terminal of the MMI

functions (in this configuration the user commands, keyboard and display are located on peripherals connected to the Base Band through connector J02 and connector P01);

• DTE management;

• Interface management towards the Firmware of Lower MAC resident on DSP;

• Terminal identification management;

Technical Description

The radio has a single synthesiser. This simultaneously produces the local oscillators for both RX and TX in such a way that the reception of a RX frequency can take place at the same time as the transmission of a TX frequency spaced from the RX frequency by a 10 MHz duplex step. In this way the radio switches from the reception on a downlink slot to the transmission on an uplink slot on the same physical TETRA channel (and vice versa) in zero time. Obviously, when the radio is allocated by the network to a physical channel of another TETRA radio channel, the radio requires a switching time (typically less than 7 ms in a 10 MHz band) in order to switch the radio to the new pair of uplink and downlink frequencies. Note that the radio, not having a duplexer nor the necessary insulation between RX and TX, cannot receive and transmit simultaneously and thus remains of the half-duplex frequency type.

2.3.2.1 Functional description

The block diagram of the R/T card is shown in Fig. 2.9. The description of the individual blocks that made up this card, is given below.

The received signal enters the R/T card through the J13 connector and than it is sent to the front-end stage.

The front-end stage complies with the normal criteria for conventional tuneable receivers. Frequency selectivity is provided by a tuneable π LC cell that is placed

before the active element (BJT) and by another two analogous cells after the same BJT.

These three cells, which use Varicaps, are tuned through VT1, VT2 and VT3 voltage signals generated by a series of 12 bit DACs.

The total gain is G = 11 ± 1 dB in the centre of the band and its variation within the band is ± 1.5 dB.

The front-end output is connected to a mixer together with the signal coming from the VCO (SD3) local oscillator to carry out the first IF (Intermediate Frequency) conversion at Fif1 (see Tab. 2.4).

Note that in reception a 3-conversion scheme has been adopted. The SD3 local oscillator, set at Flo1 (see Tab. 2.4), is a VCO (Voltage Controlled Oscillator) is controlled by the Dual PLL SA7025 (see Fig. 2.9). The signal supplied by the VCO SD3 is obtained from the Temperature Compensated Oscillator (TCXO) SD1 (see Fig. 2.9).

Technical Description

Note that in Trunking Mode, the SD3 oscillator will be at the frequency necessary to generate the TX carrier (in Trunking Mode the operating transmitted frequency is 10 MHz down translated respect to the reception frequency). This enables a common SD3 in the RX/TX paths.

After the first conversion, the received signal is passed to the first intermediate frequency block (IF block) where it is firstly amplified, than filtered and finally amplified again. Successively the received signal enters the AD607 component, where a second frequency conversion from Fif1 to Fif2 takes place (see Tab. 2.4). For this operation the local oscillator is the same VCO SD2 (set at Flo2) used for TX carrier generation (see Fig. 2.9 and Tab. 2.4).

Finally the last conversion from Fif2 to I and Q base band components is carried out in the I/Q Demodulator block with PLL frequency set at Flo3 (see Tab. 2.4).

The TX carrier (obtained by means of the mixer that combines SD2 and SD3 signals) is filtered by a group of four tuneable π LC cells (controlled by VT4 to VT7

signals) in order to filter out the undesired products of the mixer before being amplified. The Tx carrier is then divided into two separate paths through the Splitter. One part is sent to the Cartesian Loop passive I/Q Demodulator, which serves to linearize the P.A. signal and the other to the phase shifter realised by using a passive I/Q Modulator. The phase displacement introduced by this block is a function of the VIB and VQB control voltages and determines the Loop stability.

The phase shifter output is sent to the I/Q Modulator. The low frequency components at the input of this modulator are the results of a summing block (closing of the Loop and the direct line feedback) dependent on the ITX and QTX components. These are generated by the DAC TX AD1866, by the TX feedback loop demodulated signals and by the IOB and QOB controls for residual carrier rejection.

The AD1866 receives, through the J15 connector, I and Q components for serial lines transmission and generates ITX and QTX low frequency components for the modulator.

The modulator output is amplified and then passed to the P.A. card input through the J11 coaxial connector. The blip from the P.A. directional coupler (feedback loop input) enters the vehicle R/T card through the J12 coaxial connector.

2.3.3 P.A. card

The TETRA vehicular amplifier is housed on the solder side of the R/T card near the dissipation fins. The P.A. card amplifies the RF input signal coming from the R/T card in order to supply a power output of 40 dBm in the vehicular radio operating frequency range (the operating frequency range is different according to the VS 2001 different versions: see Tab. 1.2). The RF signal amplification is obtained via a line that consists of a bipolar technology transistor polarised in class AB, driven by an LDMOS technology power module.

P/N: 779-0373/02 Revision 02

Marconi Proprietary information

Page 41

VS 2001 Technical Handbook

Technical Description

The P.A. card interfaces with the Base Band card through the J06 connector. It also interfaces with the R/T CARD through the MCX type radio-frequency connectors: J14, J15 and J16. The J14 connector provides the RF signal input from the VCO. The J15 connector carries the signal from the antenna to the receiver input. The J16 connector returns the RF signal output to the R/T card and provides the linearization of the modulation. The amplified radio-frequency signal exits on the J17 connector and, through proper cable, is connected to the antenna.

2.3.3.1 Functional description

The block diagram of the P.A. card is shown in Fig. 2.13.

Fig. 2.13: Block diagram of the P.A. card

The PA ON OFF is switched on and off by acting directly on the 12 V line where a P channel MOSFET with low RDS(on) is inserted.

When the signal PAON (see par. 2.3.3.2) is at high logic level: VTX = 12 V and VRX = 0. When PA ON is at low logic level the values are inverted.

The main task of the PA ON OFF module is to amplify the RF signal generated by the RT module up to 10 W in the vehicular radio operating frequency range (see Tab. 1.2).

The RF signal generated by the R/T module, via the J14 connector, is applied to the first step U9 (variable gain amplifier) used to set PA card gain by means of the R68 network (see Fig. 2.13).

Then the signal is applied to the second step U8 (monolithic amplifier) where it is further amplified in order to drive properly the subsequent steps.

Page 42 Marconi Proprietary information

P/N: 779-0373/02

Revision 02

The signal is then adapted and connected to U7 and U6 (transistors LDMOS). Together with Q1 U7 and U6 are AB class amplifiers whose polarization is fixed by using the trimmers R51, R37 and R21 respectively.

After the received signal has been properly amplified, it is routed to the RX/TX switch that is connected, during the receiving phase, to the antenna (J15 connector).

The RF signal is then splitted, by using a directional coupler, into the R/T module for RF treatment (J16 connector) and to an additional port for ROS monitoring (VSWR Detector).

Finally, downstream the directional coupler, the signal enters a low-pass filter (LPF) and then it is connected directly to the antenna (J17 connector).
