The Fiber Development Index is based on metric data that has been gathered for each individual index factor. There are seven index factors in total: FTTH penetration, FTTBusiness penetration, mobile cell site fiber penetration, FTTP coverage, fiber density, upload speed, and download speed.

Where possible, independent country-level data sources (such as the national telecommunications regulatory authority) have been used. All data is for December 2020. Where data does not exist, Omdia has provided realistic estimations based on other factors such as leading service provider data or information.

All other research presented in this paper is based on Omdia’s extensive research around broadband and optical fiber networks, including market trackers, in-depth market forecasts, and consumer and enterprise surveys.
