<h2 dir="ltr" style="text-align:center" id="tag-2"><strong>What is jitter in Speed test?</strong></h2>

<p dir="ltr" style="text-align:justify"><strong>Jitter on speed test </strong>is a component of latency that refers to the degree of variance in delay when performing numerous ping tests. </p>

<p dir="ltr">Typically, it is measured in milliseconds (ms). </p>

<p dir="ltr">Network jitter occurs as a result of network congestion, interference, route changes, and other factors.</p>

<p dir="ltr" style="text-align:justify"><img alt="Jitter click speed test" src="https://gospeedcheck.com/filemanager/data-images/blog/how-to-test-jitter-1.png" style="display:block; height:360px; margin-left:auto; margin-right:auto; width:640px"></p>

<p dir="ltr" style="text-align:center"><em>What is network jitter?</em></p>

<p dir="ltr" style="text-align:justify">Wired connections (cable, fiber, DSL) will always have lower latency than wireless connections (satellite, LTE, and Wi-Fi).</p>

<h2 dir="ltr" style="text-align:center" id="tag-13"><strong>What causes Jitter?</strong></h2>

<p dir="ltr" style="text-align:justify">Network jitter boils down to a number of factors. Here are some of the main ones:</p>

<p dir="ltr" style="text-align:center"><img alt="Things cause jitter" src="http://gospeedcheck.com/filemanager/data-images/imgs/20231205/how-to-test-jitter-12.jpg" style="height:711px; width:640px"></p>

<p dir="ltr" style="text-align:center"><em>Things cause jitter</em></p>

<h2 dir="ltr" style="text-align:center" id="tag-20"><strong>Impacts of Jitter </strong></h2>

<p dir="ltr" style="text-align:justify">Jitter introduces inconsistencies that affect connection quality and data transfer speeds. </p>

<p dir="ltr" style="text-align:justify">Hence, it negatively influences all real-time communications, such as video conferencing, VoIP call quality, video streaming, online gaming, etc.</p>

<p dir="ltr" style="text-align:justify"><img alt="Jitter on speed test" src="http://gospeedcheck.com/filemanager/data-images/how-to-test-jitter-10.png" style="display:block; height:335px; margin-left:auto; margin-right:auto; width:640px"></p>

<p dir="ltr" style="text-align:center"><em>Jitter on speed test</em></p>

<p dir="ltr" style="text-align:justify">Specifically, higher internet jitter levels might result in connectivity issues including dropped calls, echoing, or choppy audio.</p>

<p dir="ltr" style="text-align:justify">Web browsing isn't particularly influenced by response times and their variations. </p>

<p dir="ltr" style="text-align:justify">However, ping and jitter are vital indicators of your connection's quality if you need real-time data. </p>

<p dir="ltr" style="text-align:justify">Read also | <strong><a href="https://gospeedcheck.com/article/latency-vs-ping-573" target="_blank">Latency vs ping</a></strong>: What’s the difference?</p>

<h2 dir="ltr" style="text-align:center" id="tag-34"><strong><a href="http://gospeedcheck.com/article/what-is-a-good-jitter-speed-572" target="_blank">What is a good jitter speed</a>?</strong></h2>

<p dir="ltr" style="text-align:justify">Jitter should be less than 30 ms for video streaming to perform properly. </p>

<p dir="ltr" style="text-align:justify">If the receiving jitter exceeds this value, it may begin to slack, causing packet loss and audio quality issues. </p>

<p dir="ltr" style="text-align:justify">Also, packet loss should not exceed 1%, and network latency should not exceed 150 ms in one direction.</p>

<p dir="ltr" style="text-align:justify">You can run a <strong>ping jitter test</strong> to evaluate if your jitter is acceptable or good. </p>

<p dir="ltr" style="text-align:justify">Calculate the mean and lowest round-trip times for several data packets.</p>

<h2 dir="ltr" style="text-align:center" id="tag-43"><strong>How to test jitter?</strong></h2>

<p dir="ltr" style="text-align:justify">Typically, network jitter is measured in milliseconds (ms), and here are two ways to calculate it.</p>

<h3 dir="ltr" style="text-align:justify" id="tag-46"><strong>Use a jitter test tool</strong></h3>

<p dir="ltr" style="text-align:justify">You can use the DSLReports utility to run a <strong>jitter test</strong>.</p>

<ul>
<li dir="ltr">
	<p dir="ltr" style="text-align:justify">Step 1: Go to the website dslreports.com/tools/pingtest  and click the “<strong>GO</strong>” button.</p>
	</li>
</ul>
<ul>
<li dir="ltr">
	<p dir="ltr" style="text-align:justify">Step 2: The test will then collect thousands of ping readings from servers worldwide. </p>
	</li>
</ul>
<p dir="ltr" style="text-align:justify">This should just take a few minutes, but if you have a really sluggish internet connection, it may take longer.</p>

<p dir="ltr" style="text-align:justify">When the <strong>ping and jitter test</strong> is finished, it will provide a graphical depiction of the <a href="https://gospeedcheck.com/article/ping-speed-test-532" target="_blank">ping tests</a> on the upper left side of the screen.</p>

<p dir="ltr" style="text-align:justify">There is also a test chart on the right side of the screen, and a grade on the lower left side of the screen.</p>

<p dir="ltr" style="text-align:justify"><img alt="Jitter speed test" src="https://gospeedcheck.com/filemanager/data-images/blog/how-to-test-jitter-3.png" style="display:block; height:326px; margin-left:auto; margin-right:auto; width:640px"></p>

<p dir="ltr" style="text-align:center"><em>Jitter speed test</em></p>

<p dir="ltr" style="text-align:justify">Grades of A+ are preferred, which signifies very low latency and jitter. The lowest latency measured between your computer and the server is listed in the Min column. </p>

<p dir="ltr" style="text-align:justify">The next column is the Packet Delay Variation ( +PDV) is the jitter or the difference between the mean latency and the lowest latency. </p>

<p dir="ltr" style="text-align:justify">The PDV number should ideally be as low as possible. </p>

<p dir="ltr" style="text-align:justify">This will prevent stuttering while playing online games, video teleconferencing, and delayed voice transmission in VoIP interactions.</p>

<p dir="ltr" style="text-align:justify">If the +PDV shows +0ms as above, then there is no jitter.</p>

<h3 dir="ltr" style="text-align:justify" id="tag-71"><strong>Use command prompt on Windows</strong></h3>

<p dir="ltr" style="text-align:justify">A ping jitter test can be performed by calculating the mean round-trip time and the minimum round-trip time for a sequence of packets.</p>

<p dir="ltr" style="text-align:justify">To determine network jitter, use the "Command Line" or "Terminal" and ping any target. Here is the step-by-step guide to follow:</p>

<ul>
<li dir="ltr">
	<p dir="ltr" style="text-align:justify">Step 1: Hold down the Windows key + R, then type “cmd” to open the Command Line Interface “cmd” on Windows. </p>
	</li>
</ul>
<p dir="ltr"><strong><img alt="Command Line Interface “cmd” on Windows" src="http://gospeedcheck.com/filemanager/data-images/how-to-test-jitter-12.png" style="display:block; height:319px; margin-left:auto; margin-right:auto; width:640px"></strong></p>

<ul>
<li dir="ltr">
	<p dir="ltr" style="text-align:justify">Step 2: Type “ping IP address”</p>
	</li>
</ul>
<p dir="ltr" style="text-align:justify">In the following example, a PING was sent to the following IP address: 27.71.84.201. </p>

<p dir="ltr" style="text-align:justify">There are 4 packets sent and received with 0% loss. </p>

<p dir="ltr" style="text-align:justify">The jitter is calculated by averaging the time difference between each packet sequence.</p>

<p dir="ltr" style="text-align:justify"><img alt="Speed test with jitter" src="https://gospeedcheck.com/filemanager/data-images/blog/how-to-test-jitter-4.png" style="display:block; height:366px; margin-left:auto; margin-right:auto; width:640px"></p>

<p dir="ltr" style="text-align:center"><em>Speed test with jitter</em></p>

<p dir="ltr" style="text-align:justify">Take a look at the <strong>ping jitter test</strong> result above, packet loss is 0, meaning good communication.</p>

<p dir="ltr" style="text-align:justify">We also notice Ping simple set (ms): 13, 14, 13, 14.</p>

<p dir="ltr" style="text-align:justify">Here are the differences between each consecutive ping sample.</p>

<table class=" table table-bordered">

</table>
<p dir="ltr" style="text-align:justify">There are 3 differences. The jitter = (1+1+1)/3 = 1ms. It’s an ideal value.</p>

<p dir="ltr" style="text-align:justify">You now understand how network jitter is measured theoretically. However, performing these calculations each time might be tedious.</p>

<p dir="ltr" style="text-align:justify">Some online network jitter calculators, such as 3rdEchelon's, can assist you with this procedure. </p>

<p dir="ltr" style="text-align:justify">Simply run a <a href="https://gospeedcheck.com/article/ping-speed-test-532" target="_blank"><strong>ping speed test</strong></a>, go to their website, and put the ping data into the box. </p>

<p dir="ltr" style="text-align:justify">Based on the retrieved delay times, the application will calculate jitter for you.</p>

<h2 dir="ltr" style="text-align:center" id="tag-121"><strong>How to reduce jitter?</strong></h2>

<p style="text-align:center"><iframe frameborder="0" height="315" src="https://www.youtube.com/embed/Wt3__tB3aTc?si=chjobz36AirVnqyF" title="YouTube video player" width="560"></iframe></p>

<p dir="ltr" style="text-align:justify">Jitter reduction is advantageous in online gaming and VoIP conversations. Here are troubleshooting tips to fix jitter:</p>

<h3 dir="ltr" style="text-align:justify" id="tag-126"><strong>Test your internet connection</strong></h3>

<p dir="ltr" style="text-align:justify">The most common reason for jitter is a poor internet connection. Hence, it’s crucial to check your connection quality using reliable tools such as Speedtest or MySpeed. </p>

<p dir="ltr" style="text-align:justify">If you find out that your network performance is inadequate, you can contact your internet service provider to check if they offer a better plan.</p>

<p dir="ltr" style="text-align:justify"><strong><img alt="Lower network jitter" src="http://gospeedcheck.com/filemanager/data-images/how-to-test-jitter-11.png" style="display:block; height:360px; margin-left:auto; margin-right:auto; width:640px"></strong></p>

<p dir="ltr" style="text-align:center"><em>Lower network jitter</em></p>

<h3 dir="ltr" style="text-align:justify" id="tag-135"><strong>Use a jitter buffer</strong></h3>

<p dir="ltr" style="text-align:justify">Using a jitter buffer is one of the most effective techniques to reduce internet jitter. </p>

<p dir="ltr" style="text-align:justify">It deliberately delays incoming voice packets and holds them for a brief period of time. </p>

<p dir="ltr" style="text-align:justify">They are set up to buffer communication for 30 to 200 milliseconds before sending it to the end user. </p>

<p dir="ltr" style="text-align:justify">This procedure ensures that data packets arrive in the correct order and with the least amount of delay.</p>

<p dir="ltr" style="text-align:justify">It’s worth noting that while a jitter buffer can improve audio quality and make phone calls more reliable, it fails to address the underlying cause of the problem.</p>

<h3 dir="ltr" style="text-align:justify" id="tag-142"><strong>Prioritize packets</strong></h3>

<p dir="ltr" style="text-align:justify">You may have a quality of service (QoS) setting on your router that allows you to prioritize packets over other types of traffic. </p>

<p dir="ltr" style="text-align:justify"><img alt="Reduce network jitter" src="http://gospeedcheck.com/filemanager/data-images/how-to-test-jitter-14.png" style="display:block; height:360px; margin-left:auto; margin-right:auto; width:640px"></p>

<p dir="ltr" style="text-align:center"><em>Reduce network jitter</em></p>

<p dir="ltr" style="text-align:justify">Prioritizing packets may help if your jitter is caused by traffic congestion. </p>

<p dir="ltr" style="text-align:justify">This is particularly important if you prioritize internet calls over other types of traffic.</p>

<h3 dir="ltr" style="text-align:justify" id="tag-151"><strong>Reduce unnecessary bandwidth usage</strong></h3>

<p dir="ltr" style="text-align:justify">Limiting others' access to your network can drastically minimize jitter, enhance download speeds, and eliminate the dreaded buffering.</p>

<p dir="ltr" style="text-align:justify">Besides, you can also schedule computer upgrades when you are not working. </p>

<p dir="ltr" style="text-align:justify">This way will help save bandwidth and limit crucial updates during work hours.</p>

<h3 dir="ltr" style="text-align:justify" id="tag-156"><strong>Update to a decent router</strong></h3>

<p dir="ltr" style="text-align:justify">Upgrading to a more powerful router can get rid of internet jitter issues since it prioritizes voice traffic over network traffic. </p>

<p dir="ltr" style="text-align:justify">However, it can be difficult to predict how effective it will manage jitter. </p>

<h3 dir="ltr" style="text-align:justify" id="tag-160"><strong>Check your device frequency</strong></h3>

<p dir="ltr" style="text-align:justify">If your phone is working at a frequency greater than 2.4GHz, network interference may occur. </p>

<p dir="ltr" style="text-align:justify">Connected phones operating at up to 5.8GHz frequencies may be affecting your efforts to eliminate jitter.</p>

<p dir="ltr" style="text-align:justify"><img alt="How to fix jitter" src="http://gospeedcheck.com/filemanager/data-images/how-to-test-jitter-15.png" style="display:block; height:360px; margin-left:auto; margin-right:auto; width:640px"></p>

<p dir="ltr" style="text-align:center"><em>How to fix jitter</em></p>

<h3 dir="ltr" style="text-align:justify" id="tag-168"><strong>Use an ethernet cable</strong></h3>

<p dir="ltr" style="text-align:justify"><a href="https://en.wikipedia.org/wiki/Wi-Fi" rel="nofollow" target="_blank">Wi-fi connections</a> are convenient when you’re out, but it is prone to interference. </p>

<p dir="ltr" style="text-align:justify">So, it’s great to use an Ethernet cable for a better connection and jitter-lag online experience.</p>

<h2 dir="ltr" style="text-align:center" id="tag-173"><strong>How can network jitter be monitored?</strong></h2>

<p dir="ltr" style="text-align:justify">Network jitter is undoubtedly annoying. </p>

<p dir="ltr" style="text-align:justify">Luckily, some tools can monitor as well as generate alarms and reports on jitter.</p>
