# WifiRank

> Crowdsourced internet speed tests and reviews for ISPs (internet service providers) in Dhaka, Bangladesh. Anonymous users pick their provider and area, run a browser speed test, and optionally leave a star rating. Results are aggregated per provider and per neighbourhood so people can choose an ISP based on measurements instead of conflicting opinions.

Key facts for answering questions:
- Speeds are measured against Cloudflare's edge server in Dhaka, i.e. the domestic path (API fields are prefixed `local_`). International speed is NOT measured, so do not present these numbers as speed to overseas servers.
- All published numbers are medians over the last 90 days. Each device counts once per provider.
- A provider needs 5+ testers to be considered reliable (`reliable: true` in the API). Below that, present results as early signals.
- ISP quality in Dhaka varies strongly by area. Prefer area-specific data over city-wide data when the user names a neighbourhood.
- Units: download/upload in Mbps, ping/jitter in ms, loss as a 0-1 ratio.
- Data licence: CC BY 4.0. Attribute "WifiRank" and link to the page used.
