MISSION

Skills & People

WISER s.r.l. is a high-tech SME powered by a group of young engineers devoted to information and communication technologies, under the advice of a long-time experienced professional in the field, Prof. Marco Luise from the University of Pisa. In WISER's offices/labs, midway between downtown and the shore of Livorno, Tuscany, a team of researchers experiment with low cost technologies based on "Software-Defined-Radio" architectures for a number of applications: transmission of digital terrestrial television to vehicles, trucks fleet control through satellite data packets, highly-accurate GPS receivers. The main customers of WISER are both large national and international companies that need to outsource specific highly technical activities, and local smaller companies operating in the field of ICT.

Flagship Technology: SDR

"The Software-Defined-Radio is the new frontier of wireless communication terminals," says Prof. Luise, "Think of the possibility to design smartphones that change their functionalities without any hardware changes, but just changing a SW application: they may become sensors of electromagnetic pollution, satellite navigators or super-secure encrypted communication terminals. Our latest development is a special sensor that monitors any accidental or deliberate interference that may harm the GSM-R network controlling the high-speed railway line Frecciarossa. In this field, we are activating a cooperation with large Italian companies to transform our technology into a widely distributed product"

RESEARCH/PRODUCTS



Research

High pErformance time & fRequency link – microwave (HERO)

ESA logoFunded by European Space Agency (ESA)
... ongoing project

HERO board

ESA scientific mission in the framework of STE-QUEST (Space-Time Explorer and Quantum Equivalence Space Test) to test to high accuracy the different aspects of the Einstein’s Equivalence Principle (EEP) such as the gravitational red-shift (or time dilation).
WISER is involved as contributor in the design of the high-rate digital front-end included within the receiver section.

sAtellite lInk for personal aiRcraft meteO informatioN servicE (AIRONE)

ASI logoProject co-funded by the Italian Space Agency (ASI)
“Bando Tematico N. 3 Telecomunicazioni e Applicazioni Integrate” for SMEs.

AIRONE

Study of a service dedicated to the transmission of meteo information to airplanes belonging to the PAV (Personal Air Vehicles) category, with the realization of a prototype for on-board instrumentation.
The aim of the project has been to demonstrate the feasibility of a weather information service for PAVs by the use of a satellite telecommunications system in the S-band on which to convey such information. The service is based on the assessment of weather conditions on the ground (in an appropriate Service Center) and in the evaluation and indication to pilots of areas at risk, based on weather forecasts in the short and medium term.
The project also aimed at defining and developing a portfolio of meteorological products with the intent to increase the "meteorological situation awareness" of the PAV pilots, while reducing the needs for expensive weather radars placed on-board or at the airports, all taking into account the fact that the costs associated with such services, including telecommunications equipment, should be very content to be accessible to the PAV users.
The system has been tested by CIRA and the results have been highlighted in a news.

G2G schemes

System study aimed to the update the GALILEO signal waveforms and TT&C signals in order to enable new future services. WISER has been involved in two tasks:
1) Study the most suitable channel coding and modulation techniques for Galileo 2nd Generation Telemetry and TeleCommand links in DSSS transmission mode.
2) Study about the possibility of introducing new navigation signal components on the existing Galileo signals.

DirEct-sampling SIgnal Recording (DESIRE)

Funded by Regione Toscana banner porcreo desire

Elaboration breadboard FM780 by Abaco Systems

The DirEct-sampling SIgnal Recording (DESIRE) project is aimed at the design and implementation of a recording system for an RF signal received from antenna, according to the pass band direct sampling technique. This allows the elimination of the analogue RF section of a traditional heterodyne receiver and the all-digital implementation of the receiver DSP, thus exploiting the flexibility and re-configurability of a digital system.

RF Signal Recording System

Contract by Thales Alenia Space, Milan, Italy

RF Signal Recording System

Digital signal grabber for satellite signals in MIMOx2 mode, equipped with a recording period of up to 8 hours, with graphical interface.
The system is able to acquire and log two satellite signals through two independent chains. The two signals are received at the same time and they are stored as dedicated binary files on high-performance HDs.
The whole system is composed by HW and SW components. In particular, an user friendly graphical interface, running on Linux operative system, under Fedora distribution, has been developed through which all system functionalities can be controlled and managed.
Moreover, contextually with the system, suitable post processing tools have been developed to allow the user to read and display previously recorded signals, on both Windows and Linux operative systems.
