Dial-Up Internet History and Speeds, What Came After, and How Speedify Combines Connections

Internet Connectivity – from Dial-Up to Starlink and 6G Cellular

Dial-Up Internet Access: How It Worked and How Fast It Was

Dial-up was the main way to connect to the Internet from the early 1990s well into the 2000s. A dial-up connection uses the telephone network to reach an Internet service provider by dialing a phone number. A modem turns data into audio signals and back, which made those screeching sounds you may remember.

Dial-up was painfully slow: speeds ranged from 28.8 kbps to 56 kbps. Even so, in 2022 more than 300,000 households in the United States still had a computer with a dial-up connection alone.

Benefits:

• Widely available (if you had a phone line).
• Affordable.

Disadvantages:

• Slow speeds.
• Tied up the phone line: you could either go online or use the phone.
• Frequent disconnections.

ISDN (Integrated Services Digital Network): The Digital Upgrade to Dial-Up

ISDN was the next generation of dial-up Internet access, working over digital phone lines that carried information in digital form. ISDN could send data, voice and video at the same time over one phone line, and it was popular as an alternative to dial-up during the 1990s and 2000s.

In terms of speeds, ISDN could handle up to 128 kbps, more than double dial-up’s 56 kbps. ADSL quickly replaced ISDN as the customer-facing solution for connectivity. ISDN has largely disappeared on the customer side, remaining in use only in niche roles like dedicated teleconferencing systems and similar legacy systems.

Benefits:

• Better call quality.
• Faster connection.

Disadvantages:

• Limited availability.
• Costly at the time.

DSL and ADSL (Digital Subscriber Line): Broadband Over the Phone Line

DSL (Digital Subscriber Line) is a group of technologies that are used to send and receive digital data over telephone lines. It can also be considered among the first broadband Internet access solutions. Asymmetric DSL (ADSL) is the most used type of DSL for consumers, where the download rates are higher than the upload rates. It was widely used during the early to late 2000s.

Depending on the generation of ADSL broadband, typical speeds were around 10 Mbps for ADSL1 and 24 Mbps for ADSL2+. DSL is now being phased out in favor of fiber and 5G, and many US providers no longer sell new DSL plans, yet the vast majority of US households still have DSL coverage. If DSL is what you have, pairing ADSL with 4G/5G cellular adds speed and a fallback.

Benefits:

• Always-on connection.
• Faster downloads.

Disadvantages:

• Upload speeds were slower.
• Distance from the Internet service provider affected performance.

Cable Internet: Broadband Over TV Coaxial Cable

Cable Internet has brought broadband connectivity in millions of homes around the world. Given that it used already existing coaxial cable infrastructure for delivering TV signal, it was widely adopted starting with the 2000s and it’s still in use in many households.

In terms of speeds, users likely get speeds from 50 Mbps to 200 Mbps.

Benefits:

• Higher speeds.
• Used existing cable TV lines, so it was available in most towns.

Disadvantages:

• Speeds could drop during peak hours.
• Shared bandwidth.

Fiber Optic Internet: The Fastest Wired Connection Today

Fiber optics is the latest upgrade in terms of wired Internet access for home and businesses. Data is transmitted through fiber optics from the ISP directly to the customer’s premise, where it goes through a modem and then the data is sent to a (wireless) router or another network equipment. It’s been around on a wider scale since the 2010s and many ISPs are transitioning to this to upgrade their older dial-up, ISDN, ADSL and cable infrastructure.

Fiber internet speeds currently reach up to 10 Gbps, about 180,000 times faster than 56 kbps dial-up. Note that both fiber and cable Internet are theoretically able to transmit data at the same rates; the main difference is the split between download and upload bandwidth. On cable, download speeds are much higher than upload speeds, while fiber is symmetrical.

Benefits:

• Speeds up to 10 Gbps.
• Low latency.
• Reliable.

Disadvantages:

• Infrastructure costs.
• Limited availability in rural areas.

Cellular Internet: 2G, 3G, 4G LTE and 5G Speeds Compared

Cellular internet (mobile internet) reaches you over mobile phone networks. It arrived in 1991 with the second generation of mobile phone technology (2G), and 5G is the fifth and current generation.

2G provides basic voice and text communication, as well as some mobile data. It could deliver speeds of up to 384 kbps (GSM EDGE). 2G has been superseded by newer technologies, but such networks were still available in 2023 around the world.

3G debuted in 2001 and brought better voice quality and faster data transfer, up to 42.2 Mbps for its HSPA+ market implementation, also known as 3.5G. Such mobile networks are still widely in use around the world in 2024.

4G / LTE further enhanced the data rates, up to 100 Mbps while moving, in cars and trains, and 1 Gbps for stationary users. 4G LTE networks launched commercially in 2009, and 4G is still the most widely used cellular standard worldwide.

5G is the current cellular standard, deployed worldwide since 2019, with ultra-fast speeds, low latency and support for far more connected devices. Peak data rates reach 20 Gbps, but average speeds recorded are around 400 Mbps.

Benefits of 5G:

• Enhanced mobile connectivity for a wider range of devices.
• Enables IoT, autonomous vehicles, and smart cities.

Disadvantages of 5G:

• Coverage gaps.
• Infrastructure rollout challenges.

Satellite Internet: Wireless Broadband for Remote Areas

Satellite Internet access has been available since 1996 as a commercial solution. It’s still the best solution to get online in remote areas or when not on land. There are multiple types of satellite Internet technologies, from geostationary “classic” ones to medium and low-orbit satellites. Starlink is the best-known low-orbit network; here are the biggest hurdles SpaceX’s plan faced.

In terms of speeds, satellite Internet can transmit data as fast as 220 Mbps download and 20 Mbps upload.

Benefits

• Availability in remote areas
• Good performance for download speeds

Disadvantages

• High latency
• Depends on satellite coverage, weather and other obstructions

What Comes Next for Internet Access: 6G, Satellite and Fiber

The future of Internet connectivity holds exciting opportunities. Naturally, all the current technologies for Internet access will evolve to provide better speeds and reliability:

• 6G, the next generation of cellular, is expected to roll out around 2030.
• Satellite internet is becoming the main option for remote areas, with Starlink leading through its worldwide network of low-orbit satellites.
• Fiber internet is replacing cable and DSL in more areas, given its superior performance and more efficient infrastructure.

One thing is for sure: the Internet is going to become better and better as years go by, but so are the requirements / demands and the number of connected devices.

How to Get the Best Internet Connectivity in Any Condition

Internet connections fail for reasons outside your control: temporary problems at the internet service provider, interference, weather or overcrowded networks. You are not the only one dealing with this, and there is something you can do about it.

Most people have at least two internet sources: a connection at home or at the office, and the 4G/5G cellular connection on their phone. Combining them, plus any others in range, gives you faster, more reliable and encrypted internet access.

Speedify is an app that combines all of your internet connections at the same time, right on your computer or phone: Wi-Fi, 4G/5G cellular, Ethernet, Starlink and satellite. If one drops, traffic moves to the others without dropping your calls or streams. With Speedify’s cellular sharing feature, devices running Speedify on the same local network can share their 4G/5G cellular connections, and a paired device can share its connection, receive one, or both.
