Project
The InSeBaLa project "Integration and Services for the Broadband: distributed desk for public administration" has both technology and services purposes.

The technological goals are oriented to create an advanced regional network, integrated in the technologies, integrated in the media, integrated and interoperable in the available resources, optimized as a whole or in some sub-bases according to merit figures to be defined and able to homogenize new technologies.

The service-related aims include the creation of some pilot services, oriented to show the advantages offered by the integration and optimization of resources in terms of accessibility, coverage and technical / economic compromise.

The application scenario is initially oriented to the public administration and aims to standardize the services usable from the workstation, allowing a high freedom of movement, making available everywhere high-tech, ubiquitous and pervasive services.

Achieved results:

  • Call from Desk (PC) to TETRA radio.
  • TETRA radio call to Desk (PC).
  • Call from TETRA radio to GSM cell phone.

SUMMIT

SUMMIT

(MultiMedial Ubiquitous Services for Technological Innovation and Telematics)

Coordinator: Ing. Kussai Shahin
WP5 Coordinator: Ing. Andrea Conti

Project duration: 2004-2006

Partners: Aster, Cineca, CNIT - National Inter-University Consortium for Telecommunications, CNR - National Research Council, Digicittà, University of Bologna, Rizzoli Orthopedic Institute

Project
The SUMMIT project involves the realization of research activities in the multimedia field and pursues the objective of developing a platform of "enabling technologies" (including hardware, networks and software), capable of allowing the implementation of multimedia applications in very different fields. (such as health, commerce, research and public administration) in times and at competitive costs. Furthermore, to demonstrate the potential of these technologies, three significant applications with significant value have been developed at the level of pre-competitive prototypes.
 

Among these, the CNIT UdR of Bologna coordinates the activities of design and implementation of the demonstrator related to the work-package 5 "Integrated platform and cooperative for the highly interactive intervention of laboratories distributed in the territoro, for the development, design and testing of products "in which CNIT (UdR BO, FE, PR), CNR, CINECA, Digicittà and ASTER participate.
 

The purpose of this activity is the cooperation between resources distributed in a network of RER laboratories, meaning the most general meaning possible for the term resource (instruments, devices, archives and multimedia material) to provide the user, in a transparent way and thanks to appropriate communication technologies, experiences increased compared to those possible with the resources available locally.

Thanks to the experience gained in previous projects (Multimediality, Teledoc2, VICOM) funded by CNR and MIUR,
and to the evolutions introduced with the SUMMIT project a platform was created for laboratories in the network able to:

  • configuring tools distributed over a heterogeneous network (in SUMMIT, user-friendly graphical interfaces were developed using Java, which, compared to proprietary solutions on the market, increase the portability of both the operating system and the type of terminal: PC, notebook, PDA, mobile phone ...)
     
  • configure connections (connection matrix) and programmable circuits based on DSP and FPGA (extension of the classic telemetry concept that was intended only as a configuration of instruments)
     
  • book web resources (multi-user management scheduling system)
     
  • to cooperate among distributed resources, in a transparent way for the user

MeBO

Wireless Mesh (MeBO)

The project involves the implementation of 2 or more inter-network mesh networks characterized by different technologies, in order to test the performance of the entire network and the devices that compose it.

In particular, we plan to create a MacroMesh (MM) hiperlan2, connecting various sites located in the Bologna area, and one or more microMesh (μM) WiFi, connected to the MM, able to provide connectivity in an area surrounding some buildings of the College of Engineering. These networks will then be stressed in the test phase using the traffic generated by an appropriate user.

 

MacroMesh (MM)

The MM will be characterized by a series of links linking the following sites:

Pointing antennas Tower Engineering (historic building) - Lazzaretto Engineering

Link analysis (altimetric profile, Fresnel ellipsoid and tract attenuation)

MicroMesh (µM)

As for the microMesh, connected to the MM hiperlan, we tried to identify the most appropriate areas, near the Faculty of Engineering, in which to provide 802.11 connectivity.

This would allow enabled students to connect via WiFi to the WiLAB site and / or the faculty to download educational materials and documents, thus allowing to test the realized WiFi mesh network.

APPLIED RESEARCH PROJECT 5% MULTIMEDIALITY DM 21.01.97 (G.U.N.28 OF 4.02.97)

National Coordinator: Prof. Ing. O.Andrisano

Project Duration: 1999-2002

The project

In recent years the evolution of services and technologies related to telecommunications has received great impetus from the pressing request by users, of increasingly rich and heterogeneous content: the need to integrate information of a different nature - voice, images and data - in a single flow of information usable through a multiplicity of different technological solutions, has given rise to a new type of communication, whose peculiarities are summarized in the multimedia attribute.

The creation of a modern heterogeneous telecommunications network, able to efficiently manage new multimedia services, is today the new frontier of the research world in this sector.

As part of the three-year applied research project "Multimediality - Interactive Multimedia Network of Access to the User", funded by the Ministry of Education, University and Research, implemented by the National Research Council and coordinated at national level by Prof. Oreste Andrisano, technologies and related applications have been studied to face this challenge, with particular reference to radio, satellite and fiber optic communications.

The project has seen the participation of numerous university research units and the CNR, supported by some of the leading companies active in the sectors of services and multimedia communications, among which we mention Siemens Mobile and Marconi Communications.
