What Is The Difference Between Broadband And A Leased Line?

What Is The Difference Between Broadband And A Leased Line?

Today, businesses of all sizes are heavily reliant upon their internet connection. Therefore, Stratus is frequently asked what the best type of internet connection for a business might be, and specifically what the differences are between broadband and a leased line. Below you will fnd the differences between broadband and leased lines, as well as which we recommend you suggest to your clients and customers.


Contention is the number of users competing for a connection. When you’re sharing a network connection with others, you’ll always be competing with them for bandwidth. This means that essentially, your connection is being divided by the number of those using it. The simplest way to avoid slowing internet speeds caused by contention is to use the internet at off-peak times when you are downloading large files or using the internet heavily. However, this is not always as easily said as done.

Broadband is not a dedicated connection and therefore you share your connection with many others, fighting for connection. A leased line is a dedicated connection, and therefore there is no contention. Businesses are connected directly to the local exchange and therefore they don’t share access with local residents or other businesses.

Connection Speeds

Leased lines tend to get higher connection speeds when compared to your traditional broadband connection. However, in addition to this, they provide you with symmetrical connection speeds. This means that the download speed and the upload speed are the same. With a traditional broadband connection, the download speed is usually a lot quicker than the upload speed. The quicker the upload speed, the better the online experience will be and the easier it will be to upload data to the internet. This is particularly useful if you have a load of users or you utilise cloud technology. Large off-site backups can take hours over a traditional broadband connection but will be a lot quicker with a leased line.

A leased line connection will also be fixed, so you get exactly what you pay for, whereas with broadband, providers are only required to provide ‘best efforts’.

 Service Level Agreements (SLAs)

Service level Agreements, or SLAs, come as standard with leased lines, but not with broadband connections. A Service Level Agreement is a minimum standard that you can expect from your provider. This means that your provider will define how long fixes will take before you are due a pre-defined refund or compensation.

You have no guarantees as to the time any fix will take when it comes to broadband, and you’re not always due a refund or compensation in the event of an outage.

For a business, we’d almost always recommend a leased line over broadband. Whilst this costs more, and often ties you and your customers into a slightly longer contract, the benefits far outweigh the costs. A dedicated leased line supported by SLAs means your customers will have a robust internet connection that they can rely upon. They won’t have to worry about downtime or slow speeds being of detriment to their businesses and will be able to scale the connection in line with business growth.
