AT&T: Everything You Need to Know
AT&T, Inc. is the world’s largest telecommunications company, with revenue in the billions annually. This multinational telecommunications holding company, based in Dallas, Texas held the monopoly on telephone services in the U.S. throughout the 20th century and is currently the third-largest cellphone company in the country.
AT&T was founded as the American District Telegraph Company in 1878. It then became a subsidiary of the Bell Telephone Company (Southwestern Bell) founded by Alexander Graham Bell in 1877. In 1995, following an antitrust lawsuit, the company was rebranded as AT&T Corp.
AT&T has grown through a variety of mergers and acquisitions, most notably the acquisition of Cingular Wireless in 2006 and becoming the controlling shareholder of Time Warner in 2016. It also owns Warner Bros. Discovery.
AT&T’s key telecommunication services include:
- Cellular and landline phone services
- DSL internet
- Dedicated internet
- IoT services
- Web conferencing
What is AT&T Fiber?
AT&T Fiber is the high-speed fiber internet service from America’s number one ISP, with a consistent 5 Gbps headline maximum speed. AT&T Fiber Internet uses the latest fiber optic networking technology to deliver super-fast connectivity to your property. Fiber optic cable is completely different from the coaxial cable technology provided by cable companies. Instead, thin strands of glass conduct your data at speeds that eclipse cable and DSL.
AT&T is a leading provider of next-generation access (NGA) technology Fiber To The Property (FTTP), a last-mile networking solution that uses optical fiber rather than cable. This is part of a major nationwide transition to networks that are partially or totally fiber-based. Fiber optic broadband internet delivered enhanced speed and quality of service (QoS) when compared to cable. It has a high bit rate and capacity, making it suitable for high-throughput applications.
Optical fiber cables in the network are made from superfine glass strands that are thinner than a single strand of human hair. These flexible and transparent fibers have almost flawless clarity. Light is transmitted down the length of the optical fiber at wavelengths between 850 and 1550 nm, carrying information that is encoded using a range of modulation techniques.
AT&T offers symmetrical fiber internet speeds ranging between 300 Mbps and 5 Gbps. The upload and download speeds are symmetrical which makes this an ideal ISP for VoIP phones, telecommunication, or virtualization, which require decent upload speeds.
AT&T Fiber is currently only available in the following 21 states:
- North Carolina
- South Carolina
However, the rollout of AT&T is accelerating across the country and fiber will likely reach your neighborhood soon. If AT&T fiber is not available, you can still take advantage of AT&T’s nationwide high-speed DSL internet that comes straight through your phoneline!
AT&T Price Plans for Fiber Internet

AT&T Fiber Equipment for Home Internet
AT&T installs Optical Network Terminal (ONT) in the homes of customers. The ONT is connected to the incoming optical fiber cable and converts the transmitted lightwaves into an electrical signal and vice versa for fast internet connectivity. The ONT is usually located in your closet, garage, or utility room, or on the outside of your property in a dedicated enclosure. Once installed the INT should never be removed, even if you change provider.
AT&T also supplies Wi-Fi routers to distribute internet connectivity throughout your property. You can choose from Wi-Fi 5 and Wi-Fi 6 routers. The latest router from AT&T is the All-Fi gateway that can be used with AT&T smart wireless extenders throughout your home. All equipment comes with a mandatory $10 per month equipment hire fee included in your monthly bill.
What is Comcast?
Comcast is the largest ISP in America with coverage that spans most of the country. It provides cable broadband internet with speeds and service plans that vary according to your location. Comcast’s internet services are delivered under the Xfinity brand name since 2019.
It is a popular choice for home internet due to the visibility of the Xfinity brand and its speed and reliability. Comcast previously was known for low customer satisfaction rates, but service quality and customer service have improved in recent years.
Comcast is a global telecommunications and media company that is second only to AT&T for its size and revenue. Its cable internet subsidiary, Xfinity, provides Comcast’s home and business internet services across 40 states. Xfinity provides customers with:
- Home telephone
- Public Wi-Fi hotspots
- Broadband internet
- Virtual mobile networking
Xfinity is the number one home broadband provider in the U.S. with more than 31 million active subscribers. Xfinity Internet is predominantly cable-based but fiber broadband internet has been introduced in 48 cities and metropolitan areas.
Comcast has internet speeds that range between 75 Mbps and 6 Gbps. Download and upload speeds are mostly asymmetrical, which shouldn’t affect activities like streaming or browsing but may interfere with upload-heavy uses like VoIP or telecommuting. If you need symmetrical speeds, Comcast’s fiber plans are the best option.
Comcast Price Plans for Internet Services
Comcast Xfinity has many price plans that vary with speed and your location in the country. The published prices are promotional prices for new customers which rise after 12 consecutive months of use.
The same plan can have a $20 to $30 difference in price depending on your location in the U.S. Comcast also has contract periods of up to 2 years on certain plans and there is a 1.2 TB monthly data cap applied to all plans. As an example, we’ve provided the Xfinity plans for the northeast:

The gateways include multiple Ethernet ports for LAN home networking.
What’s the Difference Between AT&T and Comcast?
AT&T and Comcast are both big hitters but there is a big difference between the fiber service of AT&T and the regular cable connectivity of Comcast. If you have AT&T fiber coverage in your area, there are the major differences between AT&T and Comcast Xfinity:
- Consistent speeds: AT&T’s fiber service has a high quality of service and great customer satisfaction. Speeds are consistently high with little variability or downtime. This is because AT&T fiber connectivity is 100% fiber with no coax, unlike Xfinity which has a hybrid coax fiber (HFC) network for its fiber delivery.
- Symmetrical upload and download speeds: AT&T stands out with symmetrical upload and download speeds that can support even the most demanding network applications. AT&T is unique because you can rely on upload and download symmetry, even at its lower price plans.

AT&T’s CEO, John T.

This means that AT&T customers can benefit from high service quality and maximum bandwidth due to this latest technology.
A major benefit of AT&T Fiber compared to Comcast is the simplicity of its pricing. Comcast not only has many plans but also varies prices by location in the country. AT&T keeps things simple with just five plans that have no contracts, data caps, or additional charges, wherever you are in the country.
