Symmetrical Speed

An internet plan where download and upload speeds are equal, most commonly available on fiber connections. Cable and DSL plans are almost always asymmetrical with much slower uploads.

What It Means

Symmetrical speed describes an internet plan where advertised upload and download speeds are equal, for example a "1/1 Gbps" or "500/500 Mbps" plan. Symmetrical plans are the norm for fiber-to-the-home: AT&T Fiber, Verizon Fios (multi-gig tiers), Google Fiber, Frontier Fiber, Ziply, and most municipal fiber networks all offer symmetrical speeds as their standard consumer product. Cable internet has been overwhelmingly asymmetrical since the invention of DOCSIS in 1997, a 1 Gbps Xfinity or Spectrum plan typically offers 35 Mbps upload, a 29:1 ratio. DSL is similarly asymmetrical, and fixed wireless (T-Mobile, Verizon 5G Home) typically delivers 10 to 20% upload-to-download ratios. Starlink currently offers roughly 10 to 20% upload-to-download ratios. Symmetrical speed matters most for: Zoom, Teams, and Google Meet professional video calls (the upstream video is the limiting factor), cloud backup services (Backblaze, iDrive, iCloud) where uploading a 1 TB system backup takes 24 hours at 100 Mbps upload versus 3 hours at 1 Gbps upload, live streaming to Twitch or YouTube, hosting self-hosted services (home servers, security cameras with cloud backup, home automation), and content creation (YouTube uploaders, podcasters). DOCSIS 4.0, which began deployment in 2024, closes the cable upload gap by supporting symmetrical multi-gigabit service. The FCC's long-term broadband target of 1 Gbps down and 500 Mbps up formalizes the growing importance of upload. In the Broadband Grade, symmetrical fiber plans earn the maximum score in the upload subscore (10% of grade) and the fiber availability subscore (20%).
