2021 RBN Data

All the postings to the Reverse Beacon Network in 2021, along with the postings from prior years, are now available in this directory.

Some simple annual statistics for the period 2009 to 2021 follow (the 2009 numbers cover only part of that year, as the RBN was instantiated partway through that year).

Obviously, statistics that are considerably more comprehensive may be derived rather easily from the files in the directory.

Note that if you intend to use the databaseß´s reported signal strengths in an analysis, you should be sure that you understand the ramifications of what the RBN means by SNR.
