3 Products and solutions Base station RA-XXX family Radio Activity designs, manufactures, and markets radio communications equipments in all PMR bands (70/160/450MHz), both analog and digital ones. The RA-XXX is the newest family of Digital Mobile Radio Base station: DMR is the newest European digital standard, (see ETSI TS and ETSI TR ). It is a good alternative to Tetra radio systems, because the supported services are similar but the costs are smaller than Tetra. The RA-XXX base stations gives the followings features: it is fully digital but is able to automatically change the format (analog/dmr ) to facilitate a soft standard s migration it works in all PMR bands 80/160/450MHz it is fully compatible with the most common DMR terminal equipments and any analog device on the market it is designed to build simulcast or multicast multisite networks (analogue and digital) with all the needed functions built-in: automatic equalization, synchronization, timing recovery, voting system, it uses the soft diversity reception for increase the up-link RF margin and to reduce the fading effects it is able to operate with the most popular links interfaces (TCP/IP, E1/T1, UHF link, copper pairs, and mixed configurations) and it is easy to design, install and maintain it offers several IP ports to connect to a number of applications like automatic telephone line interface, PC based dispatcher desk, SCADA,... it uses a very high performance and flexible LINUX platform it is fully controllable by a powerful remote control system it is extremely robust: more than 1400 base stations installed in the past 3 years (the most in h24 continuous transmission) with about 1% of failure only it is a modular design with very compact size and a light weigh Advantages of DMR Over conventional systems Two contemporary communications over 12.5KHz bandwidth European open standard Lower minister frequency license costs per channel Increase spectral efficiency Fast and reliable data communications Smooth migration from analog systems Communication security with various level of encryptions Powerful features (ID on PTT, emergency call, text messages,..) Built-in applications (positioning over voice, telemetry, ) Easy upgradability from single repeater to network Over TETRA systems Very low infrastructure costs More coverage area Total reuse of existing conventional infrastructure (sites, power supply, ant ) Ideal for a soft migration to digital radio Easy to manage and maintain Very low power consumption (solar panel compatible) Low cost TCP/IP or UHF links between the base stations Better spectral efficiency and same main features Available in all PMR bands (70 MHz, 160 MHz, 450 MHz) Availability of simulcast solutions for low traffic and wide area coverage systems

4 About SIMULCAST A simulcast network is a very powerful and professional solution for multisite radio systems. In simulcast network all the repeaters are active on the same frequency and at the same time. Main advantages: Automatic and continuous roaming and hand-over => Easy to use, fast setup call Functioning like single big repeater => automatic and simple conference call operation All stations directly connected to the network => Integrated communication sys The same RF channel over all Network => no change of channel in the coverage area, frequency saving Multisite simulcast/multicast DMR radio networks Multisite network is mandatory when the coverage area requires more than one repeater. A multisite radio network can be realized with a multi-frequency (multicast) or with a simulcast approach. Multicast needs a frequency scanning on the terminals and doesn t guarantee real-time roaming and hand-over. Therefore many manufacturers in the past tried to build simulcast network but without good result and at a very high cost. Our speciality is the Simulcast Network. To do this it is mandatory a perfect knowledge of the protocol, RF environments and the DSP algorithms. We are very skilled in it and we designed a own base station that implements all the needed algorithms. CH1 Pipeline geometry Switch ETH Switch ETH Switch ETH Switch ETH Switch ETH CH1 Optical fiber Optical fiber Optical fiber Optical fiber TCP-IP backbone Network remote control Operative Center The simulcast solution is the best in case of emergency due to easy and fast open channel mode of operation: all people involved in emergency can listen all communications so they are continuously informed about the critical situations the regulation of network access is made by user, absolutely more intelligent and efficient than a trunking SW logic Through the Ethernet port of the base station it is easy to realize extremely flexible network s structures based on a IP/LAN backbone network. Automatic DMR telephone interface The RA-TI-01/02 performs an automatic radio to telephone and telephone to radio interfaces for DMR systems. These modules operate in standalone mode (no PC needed) and they can be used in conjunction with any RA-XXX DMR radio family. These modules contain a full LINUX RISC processor and two DSP for audio coding and decoding. A lot of applications may be available by using the extremely compact coded bandwidth and the powerful built-in functionalities. The main applications are target to the DMR radio communication Operative Centers. No scanning required. Forget your previous trouble experience on simulcast networks.

5 IP modem The RA MD1 is a Communication Controller composed of an embedded analog DCE 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 10BT/100TX) data ports. The embedded analog DCE is designed to work on a standard 2/4 wire interface, with the availability of E&M signaling, using the V.34 standard on a narrow band audio channel ( Hz). The DSP algorithms are optimized to work in very noisy or nonlinear audio channels like analog TRX, power line boosters, audio networks, and so on. The main application is as LAN Extender between two IP networks connectible through a poor audio channel. Project examples As engineering company, Radio Activity core mission is the design and develop of special projects in communication field. During several years our engineers had realized many innovative and often unique communication systems: The National maritime receiving system in HF band (3-30MHz) operating with DSP intelligent antenna s collimator Automatic Identification System (A.I.S) infrastructure for maritime rescue Digital audio matrix Radio Activity has got in his portfolio a digital audio matrix solution up-gradable up to 28 X 4W+E&M or 2W interfaces for line/ radio connection. The matrix works in conjunction with an Host PC for the connections setting. A lot of code/decode protocol are available (contact factory for applications availability) for fleet management purpose, voting system, PABX to radio interface, networks interconnection, trunking applications,. Special devices Telemetry, measurements, data collection are some example only of the capability of us: Radio Activity, thanks of his little dimension and his high skill, is able to deeply customize his products and to design new equipments or solutions to match the Customer s needs. Unlike the bigger manufacturers, Radio Activity give a real open source environment over that his partners are able to develop own applications. Give us a problem, unsolvable with common technologies: we will imagine a solution with you.
