What is bandwidth?
Bandwidth is the chapters of a network to upload and download data. Net bandwidth is the maximum volume of data you can send and receive in a measured amount of time. Information technology'southward generally calculated in megabits per second (Mbps).
When streaming video to the Internet, yous are consuming upload bandwidth. It'south essential to know your network'due south available upload bandwidth considering it enables (and also limits) the quality of your outgoing streams.
Bachelor bandwidth depends on the network router, environment, and most importantly, the connection type. For example, punch-up Internet had a maximum bandwidth of just 56 kilobits per second (Kbps). In contrast, more than modern connection types like cobweb-optic landline (622 Mbps), Gigabit Ethernet (1,000 Mbps), and 4G LTE (100 Mbps) have much higher bandwidths.
Bandwidth vs. speed
Various online speed tests offer to exam how fast your network is. Just is that the aforementioned as bandwidth? Not quite. "Bandwidth" and "speed" are often used interchangeably, nonetheless in that location is a departure between these two terms.
If bandwidth is the maximum rate for data transfer, speed is how fast data is factually downloaded or uploaded. Like bandwidth, the connection speed is also measured in Mbps.
Since live streaming involves uploading data to the Net, having aplenty upload speed is important. In fact, for successful live streaming, you lot'll need both sufficient upload bandwidth and upload speed.

Built for pro AV, Epiphan's rugged and reliable hardware encoders let you capture, stream, and record with conviction. Wherever your product teams take them, Epiphan Deject's configuration and monitoring streamline management.
As with download speed, upload speed has a set rate (eastward.chiliad., "5 Mbps upload speed") as dictated by your Internet service provider (ISP). Considering bandwidth sets the upper limit for the data transfer rate, there'southward no sense in purchasing Internet speeds from your ISP that exceed your maximum bandwidth.
Bandwidth vs. bitrate
Because raw video and audio are too hefty to upload, streamed content needs to be encoded. Encoding compresses video and audio content into a size and format that's easy to transport to the Internet.
Bitrate is the amount of data encoded per unit of fourth dimension. When it comes to streaming, information technology's normally measured in Kbps, and less frequently in Mbps. Generally speaking, the college the bitrate, the higher the video quality, and the higher the upload bandwidth required.
To encode your content, you'll use either a software encoder or a hardware encoder (like Pearl Nano, Pearl Mini, or Pearl-2). You volition set the bitrate in your encoder settings.
The total bitrate consists of the video and audio bitrates. The bitrate setting volition depend on the video resolution and frame rate. For college resolutions and frame rates, you'll need higher bitrate settings. For case, the recommended encoding settings for 4K streaming at sixty frames per 2d (fps) volition be college than that for 1080p streaming at 30 fps. Bereft bitrate volition cause your stream to appear choppy.
How much bandwidth do I demand for alive streaming?
The corporeality of bandwidth you'll demand depends on your encoding bitrate. For example, if you lot are encoding at 3,000 Kbps, you volition demand at least three Mbps of upload bandwidth. If your stream'due south bitrate is too loftier relative to your upload bandwidth, your live stream will be unreliable for viewers. For example, a stream with a 6,000 Kbps bitrate doesn't work on a network with a 5 Mbps upload bandwidth limit.
In a higher place are the general required bandwidth for streaming guidelines. For instance, the minimum bandwidth required for 1080p (HD) streaming is 5 Mbps, while the minimum 4K (UHD) streaming bandwidth is around 25 Mbps.
Different platforms (eastward.grand., YouTube, Twitch, Facebook) have dissimilar speed requirements and recommended encoding settings. And so exist sure to double-cheque before streaming.
How to ensure yous have plenty bandwidth for streaming
It'southward simple math to realize that if you accept v Mbps of upload bandwidth, your stream bitrate should be less than v Mbps. Just just how much less? Bandwidth limitations are only function of the story! You'll need to consider some additional factors to ensure the success of your alive stream.
E'er have some extra bandwidth (and upload speed) available
Ensure yous always have plenty bandwidth for streaming your broadcast – plus more. This boosted headroom acts as a buffer to account for any changes to your network. Whatever user activity on your network (e.g., Internet uploads, VoIP communication, gaming) can affect both bandwidth and upload speed.
Employ the elementary formula beneath to estimate the required bandwidth for streaming:
Nosotros recommend ever having near 1.5x your stream'southward bitrate available to account for these possible network fluctuations. For case, if your alive stream has a bitrate of 5,000 Kbps (5 Mbps), ensure you take at least vii.5 Mbps total upload bandwidth available to provide a reliable live stream. You may non need all of the calculated overhead bandwidth on a stable network, but it's always all-time to be on the condom side.
Consider your network and connection type
As we mentioned, there are many different types of Internet connectivity, including fiber-optic, cable, satellite, and cellular information. Before live streaming, consider the varying levels of available bandwidth and network reliability each option offers.
For instance, wireless cellular Internet tends to have lower maximum upload bandwidth and reliability, resulting in a lower-quality stream. Or mayhap you lot live in a rural area and take a satellite connection. In that case, you lot might want to take weather into account earlier publishing your stream.
Fiber and cable connections more often than not offering higher speeds, which are all-time suited for live streaming. For improved reliability, it'south e'er best to use a hardwired Cyberspace connexion over Wi-Fi or cellular.
Consider Internet access provider upload speeds and data caps
Many ISPs annunciate upload and download bandwidth in terms of maximum and minimum speed.
For example, an Internet packet might be advertised as "Up to x Mbps upwards and 30 Mbps downwardly". This particular "upward to" phrasing is used considering Internet speeds tin can vary. If using a cablevision network, for example, you're sharing the Cyberspace with other cable users within a geographical area, so your bandwidth may slow during "peak" periods of Cyberspace activity during the twenty-four hours.
Some ISPs as well have bandwidth usage maximums – and then be enlightened your live stream doesn't become beyond your monthly upload cap, or yous may be charged additional fees.
Running an Internet speed test is also important. You may take enough bachelor bandwidth on your network just non enough upload speed, depending on how many devices are sharing the network and the types of activities on those devices.
Ensure you have additional bandwidth if streaming multiple programs
Multi-streaming is an increasingly popular live streaming strategy that involves publishing your broadcast to more than one content distribution network (CDN) platform simultaneously. Multi-encoding, on the other hand, is a like technique that involves streaming the same program to the aforementioned CDN at dissimilar bitrates. Multi-streaming allows alive streams to achieve a greater audition, while multi-encoding helps to ensure accessibility of your alive stream to viewers of all levels of download bandwidth.
Go along in listen that each additional program you publish adds to your full outgoing bitrate and requires boosted upload bandwidth availability.
The final word
As you can run across, the required bandwidth for streaming for a reliable live broadcast depends on a variety of factors. While in that location is no "1 size fits all" configuration, residuum assured that with the right tweaking you can publish a successful and reliable live stream regardless of your network.
And recall—as a general rule of thumb, nosotros recommend your streaming upload bandwidth be at least 1.5x the combined fleck rate of all your streamed programs (when streaming in SD or above). Happy streaming!
