Aplicom 12 GSM engine with Java (J2Me) environment
Network control interface adapter for various observation equipment
TCP/IP based communications middleware for transporting data over GSM/GPRS network to / from MetMan and other network management systems
Same software (with some platform dependent libraries) can be run for example in MetMan PC to provide similar interface for directly connected devices, ex. ceilometers with DXE 421 com server.
Soundings, Wind Profiler
Microsoft Windows based measurement and data processing applications with native IP connectivity
Utilize the same communications middleware than J2Me application
