How Fast Does My Internet Need to Be?

The simplest way to determine how fast you really need your Internet to be is by assessing how you use it. Consider how many times a week you’re doing things like streaming video, playing music online, and sending large files. How would you feel if your Internet were too slow to get any of those things done?

Different activities require different levels of Internet speed.

Online Activities and Required Speed

  • High-quality music streaming: 0.16 Mbps
  • General web surfing: 1 Mbps
  • Online gaming: 1–3 Mbps
  • SD video streaming: 3–4 Mbps
  • HD video streaming: 5–8 Mbps
  • Frequent large file downloading: 50 Mbps+

How many of these activities rank as a high priority in your household? The average house needs approximately 20 Mbps. If you have a gamer in the house, or someone who loves to binge-watch the latest season of their favorite streaming show, you may need more speed than that. There are also online tools to help you determine what’s right for your household.

Once you know your required Internet speed, you’re ready to shop plans with some of the nation’s fastest Internet providers. AT&T offers a wide variety of speeds based on customer needs. Depending on the availability in your area, you can start with the most basic Internet needs at 5 Mbps or go all the way to the fastest speeds with AT&T 1000 on their fiber-optic network.††

What Makes Internet So Fast? Fiber Optics.

Fiber optics is the latest development in Internet innovation and is responsible for the fastest Internet speeds.

Fiber optics were originally developed in the 1950s to help see inside the human body before surgery. In the 1960s, engineers were able to transform this technology to transmit phone calls at the speed of light.

This makes sense because that’s what fiber-optic transmission is — light. A fiber-optic cable is a cable that contains very small strands of glass, known as optical fibers, inside insulation. Each strand is thinner than a human hair but is capable of carrying vast amounts of information.

The cables do this by carrying communication signals using pulses of light generated by light-emitting diodes (LEDs). This light travels along the core, or the center of each optical fiber strand. The core is surrounded by a layer of glass called cladding that reflects the light inward to keep any signal loss contained as the light travels through bends in the cable.

There are two types of fiber-optic cables: single-mode and multi-mode.

  • Single-mode cables have a very thin core. All the signal travels straight down the middle of this core without bouncing off the edges of the container. Your cable TV, Internet, and landline signals are generally carried on single-mode fibers wrapped into a huge bundle. These kinds of cables can send information over 60 miles.
  • Multi-mode cables contain larger optical fibers — approximately 10 times larger than the ones in single-mode cables. Light beams within these fibers can take multiple paths within the large core meaning they can take multiple different modes.

Researchers analyzing the fastest Internet connection used a seven core hexagonal arrangement to keep the size of the cable to a miniscule 0.008 inches thick. They were able to stretch this small but lightning fast cable across a one-kilometer stretch of fiber.

Multi-core fiber has great potential to dramatically increase the speed at which we all share information. However, this will require replacing millions of miles of existing fiber, so it definitely won’t be happening right away.

In short, fiber optics have a higher capacity than copper cables. Their network bandwidth is just greater. Fiber cables start at 10 Gbps (billions of bit per second), 40 Gbps, and even 100 Gbps. Not only do fiber optics offer the fastest Internet speeds, but they also provide a higher level of reliability. Light can travel longer distances without losing strength, so there’s less need for signal boosters. Plus, fiber is less susceptible to interference from things like the weather, construction, or electromagnetic interference.

What Other Types of Internet Connections Are There? Are They as Fast as Fiber?

The short answer: no. The other Internet connections won’t be as fast as fiber, but they are still fast Internet speeds in their own right.

First, there is DSL. DSL stands for digital subscriber line. It uses the existing phone lines running to homes to run a connection. The plus side to DSL is that, because it uses existing infrastructure, it’s widely available in most areas — even the most rural ones.

DSL connections are reliable, secure, and dedicated to your home. They are sufficient for email, browsing, and light Internet usage, at a very affordable price.

The other popular connection type is cable. Like it’s name, these fast Internet speeds run through the same coaxial cable that runs into your TV. This is typically a faster connection than DSL — until your entire neighborhood comes home to use the Internet at the same time. This system runs on a shared neighborhood hub, which also means it’s not always readily available in rural areas.

The advantages of cable, though, typically outweigh DSL — mostly when it comes to cable’s faster Internet speeds. It’s your choice for streaming video or playing any online games. You can also usually bundle it with cable TV service to make it more affordable. To learn more about your options, talk to one of our specialists at (866) 918-4705.

What’s the Fastest Internet in the World?

That’s a nuanced question with a couple of answers:

The fastest commercial-use Internet was recorded in 2014 in the UK. This connection reached speeds of 1.4 terabit per second (Tbps) or 0.175 terabyte (TB) in just one second.

At that speed you could download 44 uncompressed HD movies in one second or the entire English version text of Wikipedia in 0.06 seconds.

This trial, performed by French telecom companies Alcatel-Lucent and BT, remains the fastest trial using commercial equipment. The fiber-optic cables run underground between the BT Tower in central London and the east coast town of Ipswich.

Later that same year, researchers at the Eindhoven University of Technology in the Netherlands and the University of Central Florida were able to use their equipment to reach speeds of 255 Tbps, or 32 TBps. With speed like this, you could possibly transfer an entire terabyte of data in 0.03 seconds. You could also send that 1 GB movie of your cat attacking the vacuum cleaner in 0.03 milliseconds.

What Country Has the Fastest Internet Speed?

According to the Akamai Q1 2017 global average connections speed rankings, South Korea has the world’s fastest Internet connections at an average of 28.6 Mbps. The rankings are quite close, and the U.S. is not as high as you’d think:

Country Average Connection Speed
South Korea 28.6 Mbps
Norway 23.5 Mbps
Sweden 22.5 Mbps
Hong Kong 21.9 Mbps
Switzerland 21.7 Mbps
Finland 20.5 Mbps
Singapore 20.3 Mbps
Japan 20.2 Mbps
Denmark 20.1 Mbps
United States 18.7 Mbps

Where Should I Work to Be Able to Use the Fastest Internet Speeds?

Anywhere that uses a shadow network. Shadow networks harken back to the days when the Internet was brand new, connecting only a few research facilities and organizations around the world for the purpose of sharing huge data files from scientific experiments. For example NASA uses the Energy Sciences Network (ESnet) shadow network, which has Internet speeds that can transfer 91 Gbps. That’s roughly 13,000 times faster than what you’re using in your home.

This kind of speed lets scientists instantly share information as they do groundbreaking work like map the human genome. While shadow networks won’t be coming to a living room near you anytime soon, carriers like AT&T are looking to that technology to improve already impressive commercial speeds.

How To Get Fast Internet in Your Home

The world’s fastest Internet speeds are fascinating, but there was a time where people thought a telephone in every home was out of the question. AT&T was there for that, and they’ll be here to see us all have lightning-fast Internet connections.

With the innovative advances of fiber-optic technology, the world is connecting quickly. Whether you’re ready for this kind of speed, or you’re happy with the more affordable sufficient options, AT&T and DIRECTV are ready to provide all your in-home entertainment at the speed that works for you.
