According to AT&T, 4G users can expect download speeds of 14–61 Mbps and upload speeds of 3–14 Mbps on average while using its wireless network. We gathered the data speeds of over 150,000 wireless users in 2020, and AT&T averaged a download speed of 28.9 Mbps.

AT&T Network means those integrated mobile switching facilities, servers, cell sites, connection, billing systems, activation systems and other related facilities over which the Service is provided on facilities and spectrum owned or controlled by AT&T.

Business fibre (or Fibre to the Business, FTTB) provides internet at scale that can manage a high demand on the internet line. This type of fibre is more expensive, but is tailored for large numbers of concurrent users with high demands of the internet speed, uptime, and contention ratio.

AT&T Inc (AT&T) is a provider of telecommunications, media, and technology services. The company offers wireless communications, data/broadband and internet services, local and long-distance telephone services, telecommunications equipment, managed networking, and wholesale services.

Performance Characteristics

AT&T delivers internet speeds that range anywhere from 25 Mbps to 5,000 Mbps, depending on the plan and type of internet connection you have.

Our 4G LTE network is composed of the following bands: 700 MHz: Bands 12/17/29. 850 MHz: Band 5. 1900 MHz: Band 2.

AT&T's network is a GSM network, like T-Mobile's, and a VoLTE network, or "Voice Over LTE." If you're switching to an AT&T MVNO from another GSM carrier - be it AT&T, T-Mobile, or one of the many other MVNOs that run on their networks - you'll probably be in business.

Fibre services can be fully customised and tailored to suit your business needs. With speeds of up to 10Gbps, you are guaranteed to get the throughput you need for your business to stay productive.

Fibre to the home is either a GPON or AON technology. These technologies usually offer asynchronous line speeds where the download speed is higher than the upload speed. Fibre to the business usually offer a full-duplex connection meaning you will have symmetrical line speeds, the same upload and download speeds.

AT&T had the highest voice accessibility (i.e., successful call initiations), the best voice retainability (i.e. lowest number of dropped calls), and the best voice quality while Verizon had the lowest call setup time.

The main strength of AT&T was the lead it had in telephones due to Bell's innovation. This would become the base of the Bell System, a monopolistic system for decades to follow. The telephone was the invention of Alexander Graham Bell. He founded several companies, one of which was AT&T.
