5G Broadband Speed

One of the most compelling aspects of 5G technology is its potential for delivering high-speed broadband to homes and businesses. 5G broadband, also known as fixed wireless access (FWA), uses 5G networks to provide internet connectivity as an alternative to traditional wired broadband services, such as fibre internet and cable internet.

5G broadband speeds can vary depending on factors such as spectrum band, network infrastructure, and device capabilities. However, in ideal conditions, 5G can deliver speeds that surpass most existing fixed-line broadband technologies. According to Ookla's Speedtest Intelligence data, the median download speed for 5G users in the UK reached 200.39 Mbps in Q3 2021, compared to 65.98 Mbps for fixed broadband users during the same period. This represents a 204% speed advantage for 5G over fixed broadband.

In terms of peak data rates, 5G has the potential to achieve download speeds of up to 10 Gbps and upload speeds of up to 1 Gbps, with latency as low as 1 millisecond. However, these speeds are theoretical maximums and may not reflect real-world performance, particularly in areas with limited 5G coverage or high network congestion.

Fibre-optic Broadband Speed

Fibre-optic broadband, also known as fibre-to-the-home (FTTH) or fibre-to-the-premises (FTTP), is a fixed-line broadband technology that uses optical fibre cables to deliver high-speed internet directly to consumers' homes or businesses. Fibre-optic technology is renowned for its fast, reliable, and consistent performance, making it the gold standard for wired broadband.

Fibre-optic broadband speeds can vary depending on the service provider and the specific plan, but they generally range from 100 Mbps to 1 Gbps or higher. Some providers, such as Hyperoptic and Community Fibre, offer symmetrical speeds, meaning that the upload and download speeds are equal.

According to Ofcom's 2021 UK Home Broadband Performance Report, the median download speed for fibre-to-the-premises (FTTP) connections was 205.1 Mbps, with a median upload speed of 168.7 Mbps. These speeds are comparable to the median 5G download speed reported by Ookla, suggesting that fibre-optic broadband can deliver similar performance to 5G in real-world conditions.

Fibre-optic Broadband Speed

Cable Broadband Speed

Cable broadband is another widely used fixed-line broadband technology that relies on coaxial cables to transmit data. In the UK, the primary cable broadband provider is Virgin Media, which offers speeds ranging from 54 Mbps to 1.1 Gbps.

Cable broadband speeds can be affected by factors such as network congestion, distance from the provider's network node, and the quality of the coaxial cables. Unlike fibre-optic broadband, cable broadband speeds are often asymmetrical, with higher download speeds and lower upload speeds.

According to Ofcom's 2021 report, the median download speed for cable broadband connections was 141.9 Mbps, with a median upload speed of 17.6 Mbps. While cable broadband can deliver fast download speeds, its upload speeds are significantly lower than those of fibre-optic and 5G broadband, which may be a disadvantage for users who require high upload speeds for activities like video conferencing, cloud storage, or content creation.
