PRISMA Engineering S.r.l. is in Milan, Italy. We develop software, firmware and we supply professional consulting for embedded systems, Personal Computers (PC) and Workstations in GSM, GPRS, Avionics and Automation fields. We work with QNX, DSP, DOS, Windows, Unix operating system and we also develop device drivers for serial communication protocols. We develop simulator of the GSM and GPRS networks elements like: BSC, BTS, SGSN, GGSN, MSC, HLR, VLR, SMLC. The interfaces beween them are: Abis, A, Gb, Gi, Gn, Lb, Iub, Iu, Iur Our simulators support the following protocols: LAPD, SS7, MTP, SCCP, frame relay, ns, BSSGP, TCP/IP, ATM, AAL2, AAL5 According to the GSM and ITU specifications We support also UMTS protocols: SSCOP, SSCF-UNI, ALCAP SCTP, ITUN, AAL2, AAL5 List of keywords for search engines: GSM, QNX, DSP, GPRS, programmi, programmazione, RLC, firmware, embedded, MAC, systems, sistemi, device drivers, Gb, Milano, Milan, Italia, Abis, A, Italy, development, sviluppo, gprs, professional consulting, SS7, consulenza, Gi, Umts, Abis, Personal Computers, PC, computer, A, Workstations, Workstation, DOS, Windows, Unix, Avionics, Avionica, Atm, AAL2, Automation, Automazione
PRISMA Engineering S.r.l. has been collaborating for over ten years with leader companies in the avionic field, and has gained specific experience in the following subjects: 
  • On board equipment for localization functions (Tacan, Dme-p, Dme-n); 
  • Ground based navaids equipment, 
    • Radio beacons (Tacan, Vor, Dme) 
    • Instrumental landing system (ILS); 
  • Remote control system for monitoring and controlling of navaids equipment; 
  • Test and calibration systems for on board avionic equipment; 
  • Multimode aircraft doppler radar based on DSP. 
In these areas the design activities were especially concerned with embedded system development. Several applications used a PC to interface with remote control systems and test equipment, and provide the functions of monitoring, control and database. 
Rigorous real-time requirements and obvious reliability constrictions were typical of these applications, and were often resolved by means of redundancy of the most critical functional components.
