  • Internet upload bandwidth requirement for feeders

    I can't find any indication of the amount of data an FR24 receiver needs to upload to flightradar24 per second. The only relevant fact I can find is "Frame rate: over 1600 Mode-S frames per second (in high traffic areas)" but I presume this refers to frames received rather than data uploaded. I wondered if FR24 firmware zips or otherwise compresses the data before uploading.

    Anyone contemplating hosting a feeder receiver surely wants to know how much of their possibly limited internet upload bandwidth will be taken by the FR24.

    Clearly, this depends where the receiver is, but some guidelines please.

    Data consumption is 200-800 MB/month depending on coverage as described here; http://www.flightradar24.com/free-ads-b-equipment/

      Thanks. I thought I had read that page carefully, but somehow failed to see that line.

      So I make that about 5Kbps, on arbitrary assumption most traffic in 12-hour daytime period. It seems nice and light.

        Yes, that's the assumption I made too.

        However, I've been monitoring my data for the past hour and am currently (20:43Z) uploading at a rate of 56Kbps with 53 ADS-B and 63 ModeS aircraft being tracked. Providing my analyser does not crash I'll upload some 24hr graphs later this week.

          Thanks, that would be interesting. I'm away this week but will have a look on Sunday.

            The images attached show the data requirement for the FR24 receiver that I am hosting for a typical day to be read in context with the feed stats for the same receiver. The data graph is combined upload and download, download data is appropriately 1% of upload.FR24 DATA - Copy.jpg20150908STATSTOP - Copy.JPG20150908STATSBTM - Copy.JPG

              Normal ADS-B data upload is about 200-800 MB per month depending on coverage and traffic in your area. MLAT adds more data on top of that. Probably up to 5-6 times more in high volume MLAT areas.

                - Thanks. So more like 100Kbps during active hours. Too much for me, as that's about a third of my upload bandwidth.

                What's the difference between hits and positions on those graphs?

                Mike - How does MLAT increase the uploads? I thought it was just taking difference between timestamps of normally-uploaded ADS-B position reports.

                  MLAT data is uploaded more often.

                  See Post #111 from what Mike wrote.

                    Positions reported: number of aircraft positions reported to receiver.

                    Hits reported: number of updates from aircraft to receiver - regardless of update content.

                      Thanks.

                      BTW before posting I did do a search for upload figures but couldn't find any. It seems that the search results do not localise to a page, so for example my search did find the "help us increase coverage" thread but it was many pages long so the fact that there was a match on page 12 wasn't known to me and I couldn't face ploughing through it all.

                          In my experience so far I'm seeing a peak of 6.2kb/s transmit with an average of 30.2MBytes sent a day.

                          This is tracked with pfsense and bandwidthd
                          See roughly 1500-2000 planes a day.

                          EDIT*:average taken over the last week
                          Not currently MLAT
