Compare AT&T Fiber vs. Xfinity Internet | AT&T Internet

AT&T Fiber uses a 100% fiber-optic network to deliver its fastest internet speeds. Fiber-optic internet technology sends data over thin glass fibers, unlike the copper wire used in older internet systems.

Fiber-optic technology transmits as light, allowing for much faster speeds than standard copper-wire transmission.

AT&T Fiber and Xfinity Internet are both internet service providers that provide residential and business internet service, apps, and security features. 

If more than one internet provider has plans available in your area, there are plenty of great reasons to pick a home internet plan powered by the AT&T Fiber network. AT&T Fiber includes the AT&T Smart Home Manager app, internet security with AT&T ActiveArmor, and high-quality Wi-Fi-6 equipment. 

As part of AT&T’s mission to be the best connectivity provider in America, AT&T is expanding its fiber network to new cities nationwide. You can find out more about AT&T Fiber expansion.  

Many factors are considered when timing the deployment of fiber infrastructure, including, but not limited to, resources, local permitting, and even community and environmental factors. We are constantly evaluating new cities to add to the AT&T Fiber footprint.

Sometimes when checking availability, you may find that you don’t have AT&T service available at your address despite AT&T being available nearby. If this is the case, AT&T Fiber may not be available to your home yet, because your neighborhood is at the edge of our Fiber footprint. You can check out AT&T Community Forums for more information.
