Broadband Contention Ratio

What is Broadband Contention Ratio?

Broadband Contention RatioBroadband Contention Ratio is the total number of households sharing the available bandwidth on an internet/data connection.

The lower the number, the better the quality and speed of the connection.

A contention ratio of 60:1 means that a maximum of 60 households will be sharing the Internet Service Provider (ISP) connection.

The standard contention ratio was 50:1 for home broadband and around 20:1 for business broadband but BT now reports that those figures are no longer accurate.

When do you get the most internet contention?

Contention typically increases during peak times, e.g. evenings and weekends when there are more people using the internet.

What is the internet contention Ratio on my Broadband?

Internet Service Providers don’t publish or advertise Broadband connection ratios.

Instead of publishing the Contention Ratio, they provide the minimum to maximum download and upload speed.  The contention ratio is taken into consideration when they provide this estimate.
