DeKalb, AL Internet Speeds — Measured 2024
Real speed tests run in DeKalb County, Alabama during 2024 recorded a median download of 111.3 Mbps, upload of 53.5 Mbps and latency of 34.0 ms, across 2,051 measurements. That is 1.3× the US median and places it #207 of 2,425 US counties.
What these numbers mean here
The median is the typical connection, not the best one available. Half the tests in DeKalb came in below 111.3 Mbps and half above. The slower quarter of connections measured under 33.5 Mbps, while the faster quarter exceeded 235.4 Mbps — a spread that usually reflects a mix of fibre, cable and older DSL lines in the same area rather than one uniform service level.
At 111.3 Mbps down and 53.5 Mbps up, a typical household here can comfortably run several 4K streams alongside video calls. Latency of 34.0 ms is acceptable for most real-time use.
