How is bandwidth usage measured

The numbers below are the maximum bandwidth speeds according to the standard or specification. The WiFi standard This will expand the possibilities of WiFi and e. The upcoming version can be used in industrial and commercial environments in manufacturing systems, corporate networks, and test and measurement equipment. Bandwidth is most often purchased from telecommunications companies. Speeds may be higher or lower at different times of the day or under different circumstances.

Corporate bandwidth is also typically purchased from telecommunications companies. However, many corporate agreements come with contractual performance measures that must be met, including a minimum usable bandwidth, minimum uptime, and other metrics.

Additionally, bandwidth metering may be used to charge for specific usage rather than a full connection. For example, a website owner may pay the website host only for the amount of bandwidth used by that specific website over a period of time, such as a monthly billing period.

While modern protocols are pretty good about not losing any packets, limited bandwidth can still cause operations to be too long to complete, resulting in timeouts or other issues. These issues can cause application errors or database errors. When backing up or copying data over a network, too little bandwidth can cause backups to take too long, often running into other batch processes, or even main working hours.

In addition, users relying on a connection with too little bandwidth may notice long lag times between when they do something, like click a button, and the response to that action. In the case of waiting for information or other data to load, too little bandwidth can cause operations to take a long time, or even cause users to give up waiting.

For users attempting to make phone calls over a network, such as Voice over Internet Protocol VoIP , having too little bandwidth results in lower quality calls. Most VoIP systems reduce the fidelity of a call based on the available bandwidth. If the quality is bad enough, there may be actual gaps in the call where parts of the conversation are missed.

Video calls require even more bandwidth. Video calls made without the necessary bandwidth will not only result in bad sound quality, but also low quality or jittery video. If the connection is too slow, users will either have to wait a long time before the video starts while the system buffers a lot of data, or the video may stop suddenly when the system runs out of buffered video to play.

Gamers are often frustrated by limited bandwidth as well. While playing against other players online, players with faster connections see what is happening quicker, and the data about their reactions is transmitted and received faster. There a few technical issues caused by too much bandwidth. Higher capacity bandwidth, however, typically costs more.

Thus, too much bandwidth may not be cost effective. Network design and infrastructure can create bandwidth issues as well. Latency measures the delays on a network that may be causing lower throughput or goodput. A low latency network has short delays, while a high latency network has longer delays. Finding and remedying bandwidth issues helps improve network performance without costly upgrades. Tools such as Ping and traceroute can help troubleshoot basic issues.

Pinging a test server, for example, will return information on how quickly data can be sent and received, as well as average round trip times. High ping times indicate higher latency in the network. The traceroute tool can help determine if there are too many individual network connections, or hops, along the connection path.

In addition, traceroute returns the time taken by each hop. A longer time on a single hop may pinpoint the source of an issue. TTCP measures the time it takes for data to travel from one network interface to another with a receiver on the other end. This eliminates the return trip from the calculation and may help pinpoint issues quickly.

If the measured bandwidth is less than expected, further measurements can isolate the issue. Does a measurement to another interface on the same network work faster?

If so, where is the difference between the two systems? By continually measuring bandwidth, administrators can target the bottlenecks in the network. With its data gathering and graphing interface, PRTG can also help troubleshoot bandwidth problems that are not related to design. For example, by measuring bandwidth usage over time, it may be determined that certain users or applications are sometimes using higher amounts of bandwidth and causing network congestion and slowing network responsiveness and internet speed for other users.

Latency is sometimes referred to as delay or ping rate. It's the lag you experience while waiting for something to load. If bandwidth is the amount of information sent per second, latency is the amount of time it takes that information to get from its source to you.

Throughput is how much information actually gets delivered in a certain amount of time. So if bandwidth is the max amount of data, throughput is how much of that data makes it to its destination — taking latency, network speed, packet loss and other factors into account. If you have multiple devices and several family members on them at the same time, you'll need more bandwidth to keep up. Streaming, gaming and other high-capacity activities demand a certain amount of bandwidth speed to get the best experience without a lot of buffering or lag.

The FCC provides a set of guidelines for Mbps needed based on digital activity. For example, if you love to stream 4K content, you'll need 25 Mbps at the very minimum and Mbps for telecommuting or gaming. See FCC guide.

Now that we've answered the question what is bandwidth, how do you know how much you have and if it's enough? If you love to stream HD videos, download large files and enjoy multiplayer gaming, you may want to consider speed plans of Mbps and above. For all other activities like streaming music, surfing and video conferencing - anything above 25 Mbps should be enough. It all depends on how patient you are with potential buffering and slightly slower speeds when others at home are competing for bandwidth at the same time for their own activities.
