Frequently Asked Questions

General

• Question: How much data is transmitted over the wire?

Answer: During normal operations and using the the default settings, around 70 MB/day are transmitted between client and server. Sending out a small http-request every second is not very effective because it adds a significant overhead. But in case we are connected via a standing line (like (A)DSL), we just don't care about that.

• Question: I connect via a Mobile Device to the internet and I have to pay per volume. How can I reduce the amount that is transmitted between Groundstation and the Server?

Answer: There are mainly two options availiable that can be used for bandwidth optimization. The option '-i' specifies a bundle size for records. The records are cached until the bundle size is reached before the data is sent to the server. The the flarm device delivers one record per second and we have a value 5 set for this option, the server is updated every 5 seconds. The option '-j' allows to ignore a part of the data stream. Having a value 2 set for this option, only every second record is used and sent to the server.
