SA’s fastest 2024 mobile broadband tests hit over 1.3Gbps

In the 21st century, the concept of “broadband” has transcended mere technical definition to become a fundamental pillar of modern society. Far more than just fast internet, broadband is the ubiquitous, high-capacity digital infrastructure that powers almost every facet of our lives – from instantaneous communication and remote work to transformative healthcare, immersive entertainment, and robust economic growth.

Its constant evolution and expanding reach are continually redefining possibilities, making it the unseen artery through which the lifeblood of global progress flows.

What is Broadband? A Foundation of Connectivity

At its core, broadband refers to high-speed, always-on internet access that offers significantly greater bandwidth than older, slower methods like dial-up. The term itself, originating from “broad bandwidth,” signifies the ability to transmit large amounts of data simultaneously across a variety of mediums.

While technical definitions can vary, the US Federal Communications Commission (FCC) currently defines broadband as offering minimum download speeds of 100 Megabits per second (Mbps) and upload speeds of 20 Mbps, a significant increase from its earlier 25/3 Mbps standard, reflecting the ever-growing demand for faster connectivity.

This high-speed capability is achieved through diverse underlying technologies, each with its own characteristics, advantages, and limitations. Understanding these technologies is key to appreciating the global landscape of broadband deployment.

The Evolution of Broadband Technologies

The journey of broadband has been one of relentless innovation, driven by the escalating demand for digital services.

1. Digital Subscriber Line (DSL)

Emerging from the late 1990s, DSL leveraged existing copper telephone lines to deliver internet access. By operating on different frequencies than voice calls, it allowed simultaneous phone and internet use, a significant improvement over dial-up.

DSL offered speeds far greater than dial-up, typically ranging from a few Mbps up to 100 Mbps in its more advanced forms (like ADSL2+ and VDSL). However, its performance is highly dependent on the distance from the telephone exchange, leading to slower speeds for users further away. While still present in some areas, particularly rural ones, DSL is gradually being phased out in many regions in favor of newer technologies.

2. Cable Internet

Cable internet utilizes the same coaxial cables that deliver television signals. Introduced around the same time as DSL, it offered significantly higher speeds, often reaching up to 1 Gigabits per second (Gbps) or more, as technology evolved (e.g., DOCSIS 3.1).

Cable connections typically offer shared bandwidth within a neighborhood, meaning speeds can fluctuate during peak usage times. However, for many years, cable was the dominant high-speed option in urban and suburban areas.

3. Fibre Optic Broadband (Fibre-to-the-Home/FTTH)

Often considered the “gold standard” of broadband, fibre optic technology transmits data as pulses of light through thin strands of glass or plastic. Fibre offers unparalleled speeds, reliability, and bandwidth capacity, capable of delivering symmetrical speeds (same upload and download) of several gigabits per second (e.g., 1 Gbps, 2 Gbps, and even 10 Gbps and beyond are becoming available).

Its key advantages include immunity to electromagnetic interference, minimal signal degradation over long distances, and future-proofing due to its massive bandwidth potential. The challenge with fibre lies in the cost and complexity of laying new infrastructure, especially for the “last mile” to individual homes and businesses. Despite this, FTTH penetration is rapidly increasing globally and notably in South Africa’s urban centers.

4. Wireless Broadband (Fixed Wireless and Mobile Broadband)

Wireless broadband harnesses radio signals to deliver internet access.

• Fixed Wireless Broadband connects a fixed location (like a home or business) to the internet using antennas. It’s an excellent solution for areas where laying cables is impractical or too expensive. It often relies on 4G or 5G networks and can offer speeds competitive with DSL or even basic fibre.
• Mobile Broadband, delivered via cellular networks (3G, 4G LTE, and increasingly 5G), provides internet access to mobile devices like smartphones, tablets, and laptops via portable modems or hotspots. Its primary strength is mobility, allowing users to stay connected virtually anywhere within network coverage. While historically slower than fixed connections, the advent of 5G has dramatically boosted mobile broadband speeds, often reaching hundreds of Mbps and, as seen in South Africa’s 2024 tests, even exceeding 1.3 Gbps in optimal conditions.

5. Satellite Broadband

Satellite broadband offers internet connectivity via communication satellites orbiting Earth. Traditionally, this involved geostationary satellites (GEO) high above the equator, leading to high latency (delay) due to the vast distance signals had to travel. However, recent advancements, particularly with Low Earth Orbit (LEO) satellite constellations (like Starlink), have revolutionized satellite internet. LEO satellites orbit much closer to Earth, significantly reducing latency and dramatically improving speeds, making satellite a viable high-speed option for even the most remote and underserved areas where terrestrial infrastructure is non-existent.
