Testbed data collection: application platforms
Surface observation stations
• 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
