A download speed of 300Mbps allows you to stream ultra-HD video on 12 devices at the same time, or download a HD movie in 2 minutes.
If you’re using a broadband internet connection with download speeds of 300Mbps, you can comfortably stream ultra-HD quality video on up to 12 devices at the same time. Alternatively, you can download an entire music album in around 2 seconds or a HD-quality movie in about 2 minutes (increasing to 9 minutes if you’re downloading a movie in 4K ultra-HD quality).
In this article, we’ll look at what you can do on a 300Mbps connection, including for online video, music, gaming, video calls and general web browsing. We’ll also look at download times on a 300Mbps connection and at how much you’ll typically need to pay for 300Mbps broadband at different ISPs.
How Fast Is 300Mbps?
A 300Mbps broadband connection is faster than the UK’s average home broadband service which has a download speed of 63Mbps.
With a download speed of 300Mbps, you can do almost anything you’d like to do at the same time on the internet, on multiple devices at the same time. For instance, you can watch online video on 12 devices at the same time in ultra-HD (4K) quality. This increases to 60 devices at the same time if you’re watching in full HD (1080p) quality.
With a 300Mbps connection, you can also download files fairly quickly. For instance, a music album will download in around 2 seconds and a HD-quality movie will download in about 2 minutes. Browsing the internet and receiving emails should be near-instantaneous on a 300Mbps connection.
Streaming & Other Activities
If you’re using a 300Mbps broadband connection, it will support almost anything you’d like to do online. This includes browsing the web, making video calls, listening to music and watching video online on multiple devices at the same time.
In the following table, we’ve listed a number of online activities and the minimum speed required for each one. We’ve also listed the number of devices you’d be able to use at the same time when accessing these services through a 300Mbps connection.
For instance, watching online video in ultra-HD (4K) quality would require a download speed of 25Mbps on each device. You can therefore watch on up to 12 devices at the same time if you have a 300Mbps connection.
|Activity||Required Download Speed||Usable on 300Mbps Connection?|
|Web Browsing, Messaging & E-Mail:|
|General web browsing||0.1-1Mbps||✔ Yes, on 100+ devices|
|Social media, instant messaging & e-mail||<0.1Mbps||✔ Yes, on 100+ devices|
|Voice & Video Calling:|
|Skype/WhatsApp phone call||0.1Mbps||✔ Yes, on 100+ devices|
|Skype/Zoom video call||0.5-0.8Mbps||✔ Yes, on 100+ devices|
|Skype/Zoom video call (HD)||1.5-1.8Mbps||✔ Yes, on 100+ devices|
|Zoom group video call (HD)||2.5-3Mbps||✔ Yes, on 100 devices|
|Streaming Online Music & Radio:|
|Listening to online radio||0.2Mbps||✔ Yes, on 100+ devices|
|Streaming music (Spotify, Apple Music, etc)||0.4Mbps||✔ Yes, on 100+ devices|
|Streaming Online Video:|
|Watching YouTube videos (basic quality)||0.5Mbps||✔ Yes, on 100+ devices|
|Watching YouTube videos (720p HD quality)||2.5Mbps||✔ Yes, on 100+ devices|
|Watching YouTube videos (1080p HD quality)||4Mbps||✔ Yes, on 75 devices|
|Watching iPlayer/Netflix (standard definition)||1.5Mbps||✔ Yes, on 100+ devices|
|Watching iPlayer/Netflix (high definition)||5Mbps||✔ Yes, on 60 devices|
|Watching iPlayer/Netflix (4K UHD)||25Mbps||✔ Yes, on 10 devices|
|Online Gaming (installed PC/console game)||3Mbps||✔ Yes, on 100 devices|
|Cloud Gaming (Stadia/PS Now/Xbox Cloud)||10Mbps||✔ Yes, on 30 devices|
|Cloud Gaming (4K Stadia)||35Mbps||✔ Yes, on 8 devices|
For some activities like general web browsing and online music, there's no real limit to the number of devices you can use at the same time. In theory, things would still work on more than 100 devices at the same time when using a 300Mbps broadband connection. In reality, however, you might reach the limit of your home wi-fi network, which can start slowing down when you have lots of devices connected at the same time.
With a download speed of 300Mbps, you can download an entire music album in about 2 seconds. It will take 2 minutes to download a HD-quality film (1080p quality) and about 9 minutes to download an ultra-HD quality movie (4K quality).
The following table shows the expected download time for multiple different types of file on a 300Mbps connection:
|Activity||300Mbps Download Time|
|Downloading a music album:||2 seconds|
|Downloading a 2 hour movie:||27 seconds (SD quality)|
2 minutes (HD quality)
9 minutes (Ultra HD quality)
|Downloading a PC or console game:||20 minutes|
|Downloading a mobile application:||1 second|
|Downloading a high-quality photo:||<1 second|
|Downloading a web page or email:||<1 second|
If you’re calculating the download time for another file, it’s important to remember that 300Mbps stands for 300 Megabits per second (where 8 Megabits are equal to one MegaByte). For this reason, if you’re downloading a 300MB (300 MegaByte) file, it will take you 8 seconds to do this and not one second.
Home Network Considerations
If your broadband connection has a 300Mbps download speed, this refers to the speed at your router or hub. This may be different from the actual speed on your individual devices.
If you're connecting to the internet over wi-fi, the download speed on individual devices may be slower than 300Mbps. This is often due to poor wi-fi or congestion from other networks. This will stop you from getting the full potential of your broadband service. For instance, you might experience buffering when watching videos online due to poor wi-fi, even if your broadband connection is able to support it.
Where possible, you should use a wired Ethernet connection to get the fastest available speeds. If you're not able to do this, look at ways to improve the wi-fi signal in your home. Getting a wi-fi repeater or a mesh wi-fi system such as BT Whole Home Wi-Fi or Google Wi-Fi can be a highly effective way of improving speeds on your home wi-fi network.
