During the work of the ADSB receiving station, an increased consumption of mobile traffic was detected. Logging for the month showed that only 3.5GB of traffic was sent to the network. In fact, the existing mobile operator’s tariff plan had 8GB of traffic, which was exhausted in about 25 days.
The tcpdump investigation showed that the mobile operator counts traffic to IP headers.
The programs dump1090 and modesmixer2 worked in such a way that each received ADSB message (usually 16-24 bytes in size) was sent each in its own IP packet.
The headers of IP packets created traffic even larger than the data stream from dump1090 itself.
I wrote a simple program (BinBEAST Header Compressor) that replaces the modemixer at the receiving station and “packaged” data approximately 600-630 bytes into one IP packet. Thus, the economy of mobile traffic is achieved by about a third.
I think that Flightaware should implement such compression of traffic. When I received Flightfeeder, it turned out that the traffic generated by this station would not be acceptable for use with mobile Internet. I could not install the station where only the mobile Internet is available.
