How Fast is a Leased Line? Understanding Speed, Performance & Reliability

Written by Jessie Barr

When it comes to business internet, speed and reliability are everything. But not all connections are created equal. If your business relies on cloud applications, VoIP calls, or large file transfers, a leased line could be the solution to slow and unreliable broadband. But how fast is a leased line, and how does it compare to standard business broadband? Let’s break it down.

 

 

 

Leased Line Speeds vs. Standard Business Broadband

 

Leased Line Speeds

A dedicated internet line offers speeds ranging from 100Mbps to 10Gbps, with both upload and download speeds being symmetrical. This means your business can send and receive data at the same high speed, ensuring smooth video conferencing, seamless cloud backups, and lag-free VoIP calls.

 

Standard Business Broadband Speeds

Traditional business broadband connections—such as fibre-to-the-cabinet (FTTC) or fibre-to-the-premises (FTTP)—offer download speeds of up to 1Gbps, but upload speeds are often significantly lower, sometimes as slow as 50Mbps. This asymmetry can cause delays in cloud-based work and affect remote collaboration.

 

 

 

Why a Leased Line is Faster & More Reliable

 

1. Uncontended Bandwidth

Unlike standard broadband, which is shared with multiple users in your area, a leased line is dedicated solely to your business. This means you get consistent speeds at all times—no slowdowns during peak hours.

 

2. Symmetrical Speeds

Most broadband services prioritise download speed over upload speed. A leased line, however, provides equal upload and download speeds, crucial for businesses that rely on video conferencing, remote access, and cloud services.

 

3. Low Latency for Better Performance

Latency (the delay in data transmission) can impact everything from video calls to online transactions. A dedicated internet line has significantly lower latency compared to standard broadband, making real-time communication and data transfers much more efficient.

 

4. Service Level Agreements (SLAs)

Leased lines come with guaranteed uptime and rapid fault resolution, often within 4-6 hours. Standard broadband, on the other hand, may take days to repair in the event of an outage.

 

 

 

Who Benefits Most from a Leased Line?

 

A leased line is ideal for businesses that:

  • Rely on cloud-based applications like Microsoft 365, Google Workspace, and CRM systems.
  • Need seamless VoIP and video conferencing without lag.
  • Regularly upload and download large files, such as media or design firms.
  • Operate multiple locations needing secure and fast connectivity.
