I am seeking your evaluation of how well my data matches your perception.
Firstly, however, I beg pardon for cross-posting; this thread appears in other operator mailing lists. I am trying to reach as many operators as possible.
Please find here https://drive.google.com/open?id=1eZZeqbDaTj6nSJJDdK0iu5Xm9Z_691rR&authuser=etienne.depasquale%40um.edu.mt&usp=drive_fs a snapshot of two datasets concerning access technologies in the metro area. The bar chart on the left (not on the right, as inadvertently posted on NANOG) summarizes data I collected last year from *NOGs; the bar chart on the right summarizes data received through commissioned market research, from Tier 1 and/or regional operators.
The y-axis shows cumulative responses for an option; the x-axis shows monikers for the access technologies.
A second snapshot https://drive.google.com/open?id=1fMLiEGbvaD4pqCmQM75HWYoR37XaiHFQ&authuser=etienne.depasquale%40um.edu.mt&usp=drive_fs shows the same data, but this time with each response weighted by a conservative estimate of the respondent's subscriber base across all geographical regions. Here, the y-axis shows an estimate of the number of subscribers using the access technology.
Thank you for taking the time to read this.
