In practice, speeds vary depending on the source of the data and other factors. But note that the speeds it uses are estimates. The calculator above can help you estimate your bandwidth needs, based on how many different devices are in operation at any one time. However, you need as much as 25 Mbps to watch a 4K Netflix movie in HDR at its highest quality.īandwidth is closely related to speed it reflects the amount of speed available for you to use, because your whole household will share whatever internet speed you have. So if two TVs in your home are each streaming 4K movies, you need at least 50 Mbps of bandwidth. Because “bits” of data are very small, speed is usually measured in megabits, or millions of bits, per second (Mbps). Some superfast fiber services can send data at a gigabit per second (Gbps, or a billion bits per second).Īlmost any internet speed is fine for receiving a text-only email, and you may need only 1 Mbps to listen to a Spotify song. You can detect and troubleshoot WiFi and wired issues proactively even before they affect your end user.The term refers to how fast data-say, a Netflix movie-travels into your home. This allows you to capture user experience data from all your remote sites.It also enables your IT be proactive with any issues that may come up. In addition with NetBeez, you can collect measurements on dozens or hundreds of agents. On the NetBeez dashboard, you can automate the execution of bandwidth testing with iPerf and network speed to run on a specific schedule and collect the historical information to build statistics, baselines, and get alerted when something goes wrong. NetBeez works by installing agents on both wireless and wired networks that run periodic tests to measure latency, HTTP response time, bandwidth and more. NetBeez Speed TestsĪt NetBeez, we use network monitoring to detect issues that affect the end user. It will help you create a baseline that you can use to detect if there‘ are any issues that might affect your users‘s a sudden drop in throughput. The important observation with these tests is to look for changes in the measurements. If you were to ask, “ Then…which test should I use ?” I would answer: “ Pick one and be consistent ”. According to my experience, the most reliable and accurate test is iPerf. In fact, both the server and the device ramp up the upload and download process. They do this because those values tend to be lower than the average. For example, some tests discard the first few seconds worth of measurements. This is because each speed test implementation might handle data and timing differently. In addition, if you try the same test on two different browsers you might also see discrepancies in the measurements. You will notice significant discrepancies in the bandwidth measurements they provide. Try to run all of the previous five tests on the same hosts and on the same network. The benefit of using iPerf is that you have the ability to customize many parameters that are not possible to customize with the HTML-based tests. In the following table, I have sorted all these tests with respect to how easy they are to use, with being the easiest, and iPerf the least easy. In addition, it can measure some other metrics as well such as latency and jitter. It’s pretty straightforward how all of these speed tests work: a device uploads and downloads a large file to a server, and based on how long it takes, it calculates the connection bandwidth. In this post, we’ll cover five of them, their different features and how they can be used in different scenarios. There are a dozen similar tests (with every major TelCo provider having their own speed test) and a number of free and paid mobile device apps available. There are many ways to do this, but the ‘quick and dirty’ way to test the network connection is to run a speed test – such as the one provided by Ookla. But you are still tasked with proving that, “It’s Not the Network.” If you have a few years’ experience in network troubleshooting, you know that when you receive a ticket from a user complaining about “slowness”, in most cases, it’s the user’s device or the application. Also, I presented this topic at the Wireless LAN Professionals conference in February 2018. TL DR: There are so many network speed tests available: Ookla,, NDT, iperf, … which one should you use? In this article, I’ll go over this.
