3 Products overview updated 15/07/2009 PRODUCT S Radio Activity S.r.l. is a young and dynamic electronic engineering company with its operational headquarters in Milan. The company carries out design and production of wired and wireless equipment and systems for telecommunications networks in the professional market. The main products developed by Radio Activity are professional radio equipments in VHF and UHF bands for voice and data communication, IP modem and digital audio matrix systems for telephone 2/4 wire (+E/M) standard lines. All Radio Activity products are designed to interfacing with a detailed and robust remote control system. Base station Radio Activity develops rugged and powerful base stations based on DSP technology for professional radio network applications. The main characteristics of its products are modularity equipments are based on modules, each implementing a defined function, wich can be connected together in different way in order to realize different systems, from a single receiver/transmitter to a multicarrier base station; flexibility the most part of computational functions, signal elaborations, control loop and logic is assigned to software routines. In this way the DSP can manage every equipment features and by simply changing software parameters it is possible to customize the system; connectivity the base stations have got an Ethernet port to connect each other with different type of links. These links can operate with different transportation system topology, like the most popular TCP/IP link (microwave, fibre optics, LAN, WAN, ) or T1/E1 link or a pair of (UHF/VHF narrowband) base stations or 4wires+E&M. remote control every equipment gives access to the internal control serial bus. A proprietary software allows by a remote connection to download software, change current parameters, monitor the working status; digital core modulation, demodulation and audio frequency processing are fully digital; self-calibration each application variable or component tolerance dependent parameter is calculated by DSP algorithms on the basis of self-calibration processes. Calibration also allows to compensate variations due to components aging. For simulcast network, the DSP performs a very accurate synchronism reference and the appropriate delay and amplitude compensation of the signals. rugged more than Radio Activity base stations are operating for emergency and essential services in Italy and outside presently. It presents less than 1% of global failure per year. IP leased line modem The Radio Activity IP modems allowing you to connect together two LAN networks by using a 4-wire audio (leased line) connection with net speed up to 24 Kbps with 12.5 KHz channel bandwidth. Thanks to the LINUX "core" with a DSP coprocessor, the modem provides excellent performance even over noisy and distorted channels. The modem is approved for use in over the mains communication network at speeds up to 33.6 Kbps. This solution is especially suited to management and supplying electricity companies. With integrated Ethernet interface, enables to minimize the number of units to be installed and allowing to simplifying operations of system activation and maintenance. This modem should be used to perform a TCP/IP link over a twisted copper pair to realise the connection between two DMR base stations. Page 3 of 16

4 Products overview updated 15/07/2009 Digital audio matrix Radio Activity has developed a Digital Audio Matrix that can manage up to 60 lines 2/4W + E&M for line/radio or telephone/radio connections. The device works connected with a host PC for configurations setting. There are many coding/decoding protocols to achieve audio management, address, PABX interface to radio, networks interconnection systems. The matrices are designed using the latest technologies and applications in the field of Digital Signal Processing (DSP). These devices are fully programmable and easily configurable both hardware and software, thus providing excellent solutions for all needs of radio communications in order to realize Operative Centres that manage complex networks of tens of base stations. All DSP modules have a connection bus that allows flexible composition of the various blocks of the system to create "infinite solutions." MODULAR APPROACH The base station family RA-XXX has been designed using the latest technologies in the Radio Frequencies and Digital Signal Processing fields.

Using a PC, via optional SW, it is possible to set-up most of the parameters (fine frequency adjust, corner frequency of digital filters, RF deviation, audio level in/out, PTT pilot tone, ). This SW permits also a large view of the status of the transceiver (audio loop test =>, current consumption, temperature, ) and a set of measurements (audio level, frequency, distortion, delay, received field, RF power, ). The radio electric functions of the device comply with the requests foreseen by the legislations ETS e ETS The transceiver RA-XXX has a compact structure, is made up by single modular units inside metallic shielded modules so called EUROCARD with 220 mm format, assembled in SUBRACK 19. The dimensions of the subrack are 3HEx84TE, widht 280 mm. The function units are implemented as plug-in modules which are interconnected on the back plane located at the rear of the unit. It consists in some PCB (depend of use) provided with signal and supply connectors. The shielding system is very efficient and allows a quick access to the PCB, removing the slipping cover without screws. The standard power supply of the device is by battery at 13,5Vcc, 5A negative grounding. In case of functioning with other energy fonts are available more types of isolated DC/DC or AC/DC converters with battery charger. TRANSCEIVERS The following models are available (with 12.5KHz and/or 25KHz channelization each one) Mod. RA-080 Mod. RA-160 Mod. RA-450 Mod.

6 updated 15/07/2009 Products overview Analog (conventional) These modules are mounted in a standard ½ 3UT 19 rack Digital Receiver Digital Signal Processor Transmitter Branching Local Operator Power Supply Manager The basic configuration can be extended with other receivers, digital audio matrix interfaces towards 2/4 wires standard telephone lines, 1+1 configuration, multichannel transceiver, etc., by simply combining the following modules Power Supply Manager can be not isolated for a 12V battery supply, or isolated for a wide range input voltage supply (9-18Vdc / 18-36Vdc / 3672Vdc or, with an external auxiliar module, Vac); Digital Signal Processor the manager of the equipment (for complex transceivers architectures more DSP modules can work together); Page 6 of 16

7 Products overview updated 15/07/2009 Receiver can be supplied in single or double version with two channels synchronous in order to obtain a reception known as soft antenna diversity. The signals received by two antennas are put in phase and then summed up in real time before the demodulation in order to line up the antennas in the direction which grant the best quality signal. This technology allows to improve the fading functions and is useful for the analogical signals and moreover for the data traffic. Demodulation parameters are software programmable; Transmitter contains both a very low noise RF sinthesizer and a class C 25W RF power amplifier. Modulation and power parameters are software programmable; Local Operator manages the user interface and contains 2 audio interfaces towards 2/4 wires +E/M lines and 4 optoisolated software selectable criteria (2 input + 2 output); branching system can be configured in different way to allow following working modes duplex, half duplex, simplex, 1+1 configuration, multireceiver; And other modules GPS receiver signal allows the DSP to synchronize and to equalize the transceiver to the absolute time reference in simulcast systems. GSM/GPRS modem for remote control purpose These transceivers are suitable both for analog and digital communications. Digital Audio Matrix a module containing 4 audio interfaces towards 2/4 wires +E/M lines and a DSP for signals elaborations; Page 7 of 16

8 Products overview updated 15/07/2009 Digital (DMR) The same modular units, with more DSP power and an ETHERNET interface, are used to build the digital release of the transceiver. The external design was changed a little (colours) to present a more pleasant view. This transceiver is a software up-grading of the previous analog one. All the basic analog functions (S, audio, selective call, ) remain active and the new DMR standard (ETSI TS technical specification) modem are plugged over. Radio Activity DMR repeaters are designed with the double standard technology, they are able to work both in analogical and digital way, then supporting both classic PMR terminals and the new DMR ones, with every operating characteristic of each technology ( dual mode ) voice communications with FM analogical modulation and selective calling based on traditional protocols; voice communications and data transmission with 4FSK digital modulation, according to the DMR standard, with 9600 bps gross total speed. Furthermore the selection of required working mode is fully automatic, this meaning that the repeater is able to autonomously detect if the incoming communication is analogical or digital and can consequently configure itself to work as a PMR or DMR respectively. Basic model already has all the characteristics to work as a double standard repeater with all the features of analogical and digital service. It can be equipped with double receiver to counteract fading effects through diversity space reception. It is set to host communication and synchronization embedded devices to make the network expandable to a multi-frequency or iso-frequency multi-site system, with different type of links, operating with different transportation system topology, like microwave, UHF, fiber optics, generic TCP/IP connections. Privileged communication interface is ethernet standard type, maximally compatible with more diffused technology. This interface supports not only voice and data digital traffic, but also remote control management, which for Radio Activity equipment is very powerful it is possible to have a complete monitor system of equipment status, it is possible to modify each parameter, to down-load each SW and configuration, launch self-test and calibration functions, to perform specific tests through internal embedded function generators and software analyzers of the station. For analogical voice traffic instead, a 2/4 wire and criteria line interface is available. Remote control service can be performed through an ethernet connection pre-existing in the site, or through GPRS modem which can be integrated into the station, or through the radio channel and another Radio Activity station. Fully modular structure allows to best configure the radio equipment, by adding and/or changing the required HW and SW functional blocks, to work as simple repeater, multi-frequency multi-site repeater, iso-frequency multi-site repeater.

10 Products overview updated 15/07/2009 LEASED S MODEM WITH IP SERVICES RA-MD1 is a Communication Controller composed of an embedded audio modem and a high performances RISC processor, equipped with LINUX operating system, which manages the whole device and handles the HW/SW communication interfaces needed for serial and LAN (Ethernet) data ports. The typical application is the TCP/IP network extension toward remote networks or single network devices operating process control (electrical production, surging sites ). The embedded audio modem is designed to work on a standard 4 wire interface on a leased line, using the V.34 standard; it is optimized to transport the data flow over analog radio links, on which it assures great performances. For this option we recommend to use Ts of the RA-450D family, which have excellent radio electric characteristics, adapted to realize high-speed data point-to-point links. On this subject, should be noted that the RA-450D Ts process the signal through Digital Signal Processing (DSP) devices, permitting lots of functions not performed by the traditional analog Ts. In particular, the link established by these Ts, even with a 12.5KHz channeling, guarantees a Hz bandwidth with very low levels for group delay and distortion, and a high S/N level. Available on the RA-MD1 are an asynchronous serial V.24 port (DTE) destined to the remote control system, permitting the monitoring and the surveillance of both the local and the remote device an asynchronous serial V.24 port (DTE) for the data communication a 10/100 BT LAN Ethernet port for the data communication The RA-MD1 handles the communications between the serial ports, the LAN port and the embedded modem. It has its own configurable IP Address, and carries the data on a 4 wire leased line using a full-duplex PPP protocol. Page 10 of 16

11 Products overview updated 15/07/2009 The RA-MD1 can transfer data on a point-to-point radio link, realized with a couple of RA-450D Ts, at a speed up to 26.4Kbps, assuring a 19.2Kbps net bandwidth and using the extra band for diagnostic signalling, error correction and network services. Using a RISC processor with an embedded LINUX operating system assures a great flexibility for configuration and use, permitting either homogenous LAN-to-LAN or V.24-to-V.24 and mixed LAN-to-V.24 connections.

DIGITAL AUDIO MATRIX The Digital Matrix is target to Control Offices applications. The main rule of the Digital Matrix is to inter-connect repeaters or radio networks each other or to telephone lines/console. Digital audio matrix is a modular structure equipment designed to dynamically cross-connect up to 24 analog lines. Lines interface type is standard 2/4 wires + E/M with 4KHz bandwidth and the rules of cross-connection are software programmable and writable in an internal flash memory. Audio matrix is made up by 2 types of modules Power supply unit [PSU] Audio lines with DSP [4W+E+M] These modules are mounted in a standard 3UT 19 rack.

Audio lines with DSP is a module containing Page 11 of 16

12 Products overview updated 15/07/2009 with 4 independent analog line interfaces. Each line can be set as a 2 wires (PSTN) one or 4 wires one; optoisolated E/M criteria can be enabled. For specific applications lines 1 and 3 can be closed respectively upon lines 2 and 4 (both manually or automatically in case of system fault); 4 bidirectional ADC/DAC; a DSP core which performs signal conversion, filtering, elaboration and shares on a digital LAN with proprietary protocol, both digitized signals and their associated criteria. Each DSP of each module connected to the same LAN can see every digital audio flux and its related criteria. Each DSP elaboration parameter is software programmable. Up to 6 Audio lines with DSP modules can be connected in the same rack. Rules for crossconnection can be static line output signal is a fixed weighted sum of some line input signals; dynamic line output signal depends on information contained in some input signals like E value, frequency selectable superaudio tones or a sequence/combination of them, DTMF sequence; a combination of the two. Digital Audio LAN is fully compatible with transceiver s one, so the two equipment can be connected together by this bus in order to connect one or more transceivers to telephone lines. This connection allows to exchange not only audio flux, but also digital flux and criteria (allowing remote control of the device).

Products overview updated 15/07/2009 REMOTE CTROL The base station has a first useful level of remote control it sends automatically alarm messages to the mobile terminals directly. Every base station sends to the selected maintenance group of terminals a short message to inform in real time the user about the major failure happened (power supply low, IP connection fail, synchronism fail, etc.). In most cases this feature is enough to survey the correct functioning of the network by the final users. Target for system integrators and surveillance/maintenance operators, Radio Activity had developed a powerful tools for Network Management and remote surveillance and control based on Windows (XP/VISTA). A lot of functions are implemented software download, / disable, alarms report, audio level control, radio measurements, RF power, telephone to radio setup, and much more All the parameters setup are remotely modifiable by the user through the remote control SW package. There are many possibilities of connection to the station TCP/IP, serial port, over the air, modem. The most used one is via GSM modem directly connected to the stations Base station GSM modem GSM modem Base station With this connection it is possible to set all parameters of the radios and it is possible to download all firmware and software installed on the radio. All the commands sending and received from the stations don t disturb the radio communications (also during the down-load procedure). PSTN The use of GSM modem allow the Technical Assistance Unit to access to the station directly from Control Center or from a mobile PC without disturb on the radio communications.
