operating in Milan since 2003. The main activities are projects, de-

velopments and supplying of integrated telecommunication sys-

tems for Professional Mobile Radio market.

Radio Activity is a node of a network of excellence’s partners. The

research and the development carried out inside the Company in-

volves Radio Frequency, Digital Signal Processing and IP networking

fields. The Company, taking advantage of external professionals of

highest level with multidisciplinary skills, is able to create, each

Products and solutions Base station RA-XXX family

Radio Activity designs, manufactures, and markets radio commu-

nications equipments in all PMR bands (70/160/450MHz), both

analog and digital ones. The RA-XXX is the newest family of Digi-

tal Mobile Radio Base station:

DMR is the newest European digital standard, (see ETSI TS 102

361 and ETSI TR 102 335). 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, vot-

ing 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 configura-

tions) and it is easy to design, install and maintain

∞ it offers several IP ports to connect to a number of applica-

tions like automatic telephone line interface, PC based dis-

patcher 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

MHz, 450 MHz)

∞ Availability of simulcast solutions for low

traffic and wide area coverage systems

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 does-

n’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 imple-

ments all the needed algorithms.

Through the Ethernet port of the base station it is easy to realize

extremely flexible network’s structures based on a IP/LAN back-

bone 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 avail-

able 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.

Company Profile

About SIMULCAST About SIMULCAST

A simulcast network is a very powerful and

professional solution for multisite radio

systems. In simulcast network all the re-

peaters 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 cover-

age area, frequency saving

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 criti-

cal situations

∞ the regulation of network access is

made by user, absolutely more intelli-

gent and efficient than a trunking SW

logic

Company Profile

IP modem

The RA‑MD1 is a Communication Controller composed of an em-

bedded 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 (300÷3400 Hz).

The DSP algorithms are optimized to work in very noisy or non-

linear audio channels like analog TRX, power line boosters, audio

networks, and so on.

The main application is as “LAN Extender” between two IP net-

works connectible through a poor audio channel.

Digital audio matrix

Radio Activity has got in his portfolio a digital audio matrix solu-

tion 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 di-

mension and his high skill, is able to deeply customize his prod-

ucts and to design new equipments or solutions to match the

Customer’s needs. Unlike the bigger manufacturers, Radio Activ-

ity give a real “open source” environment over that his partners

are able to develop own applications.
