Post the pandemic, everything shifted online. However, a solid internet connection has become necessary now that everything has cooled down and people are opting for hybrid working environments.
But with increased demand has come poor performance. It is where jitters come into the picture. Wondering what they are? This article walks you through everything you need to know regarding jitters.
What is a Jitter?
The question “What is jitter in communication?” helps us understand the technical aspects of networking and computer technology.Jitter is the small variations in the time between packets being sent and received. Several factors can causejitter in voice calls.
What Is Jitter in VoLTE?
Jitter in VoLTE(Voice over LTE) refers to the small variations between packets sent and received during a VoLTE call. VoLTE is a technology that allows for high-definition voice calls over a 4G LTE network. Jitter can harm the quality of a VoLTE call, as it can cause delays and errors in data transmission.
Examples of Jitters are:
There are several types ofjitter in a call. This includes random jitter, caused by unpredictable changes in network conditions, and deterministic jitter, caused by predictable changes in network conditions.
Jitter in communicationcan harm the performance of a network, as it can cause delays and errors in the transmission of data.
Causes of Jitter
We will now discuss what causes jitters –
1.Network congestion: Too many users using a single connection can cause network congestion.
2.Poor hardware performance: The frequency of your device might be the reason for jitters.
3.Wireless Networks: Interferences and jitters can happen anytime, depending upon what the other users are working on despite the WiFi connections present.
4.Not implementing packet prioritization: You should prioritize choosing packets over traffic.
What Is Acceptable Jitter for the Internet?
What is a good jitter? Low jitter levels are not likely to build a noticeable impact on the phone network. There are different levels or grades of ‘acceptable jitters’ or ‘good jitter.’ These jitters are what you will accept or tolerate.
You can measure jitter in ms (milliseconds). The acceptable standard jitter is approximately 30ms, and if there is a delay beyond 30ms, it will result in disruption and distortion of a call.
Jitter should always be below 30 milliseconds for working efficiently and video streaming. If you receive a jitter higher or more than this, it will start to lag, resulting in issues with the quality of audio and packet loss.
The packet loss should not exceed one percent, and the network’s latency should not exceed 150 milliseconds in a single direction.
A greater level or grade of internet jitters might cause various connectivity issues, such as:
- Dropped calls
- Echoing and static
- Delayed calls
- Breaking audio or distortion
How to Fix Internet Jitter?
Here are some tips on how to troubleshoot and fix jitters on the internet:
1. Perform a Bandwidth Test
You can minimize the unnecessary usage of bandwidth. Perform a test on the bandwidth of your internet connection, and as per the results, you can restrict other users from using the internet.
This way, you canwork remotelywithout any significant chances of jitter. It will also increase your downloading speed and stop the dreadful buffering. You can also invest in a powerful WiFi router.
2. Upgrade Ethernet Cable
If you have a setup where you use a desktop instead of a laptop, using an Ethernet cable will be worth your time. Interferences can occur anytime, depending on what the other users are working on despite the WiFi connections.
This means that upgrading your Ethernet cable will provide you with a more robust internet connection at the workplace. You will be less likely to experience jitter in communication, and you will experience the greater speed of the internet.
3. Check Device Frequency
Sometimes, the problem is not with the internet but the calling device itself. A standard device frequency is 2.4 gigahertz, and if your device operates on a much higher frequency, you are facing jitter call quality problems. Calling devices can go to a limit of 5.8 gigahertz, which will hugely interfere with the internet connection and result in a jitter.
4. Schedule Updates Outside of Business Hours
You can also schedule device updates when you are not working. You can minimize important updates and save bandwidth during work hours. This will hugely reduce internet jitters when connected to one or more devices.
5.Manage Users
Reducing or restricting the number of users using the same internet connection will save you on a huge bandwidth that will result in high-speed online gaming and downloads, and you can work remotely from multiple devices.
6. Prioritizing Packets
Your router should contain a QoS (quality of service) setting. You can opt to prioritize packets over any other type of traffic. Opting for packet prioritizing will help you to get over the jitter causing traffic congestion. This is essential only if you deem calls more important than traffic.
7. Jitter Buffers
Jitter buffers are handy devices installed on a Voice over Internet Protocol system. It works by storing and delaying incoming voice packets. It can buffer traffic by thirty to two hundred milliseconds before forwarding it to the receiver.
The process ensures that the data packets will arrive with no or minimal delay. Some cases show that if they depend on the buffer, they can reorganize the data packets (according to the time they were forwarded or sent).
There are two kinds of jitter buffers;
- Static Jitter Buffer – This is hardware-based and usually configured by the manufacturers.
- Dynamic Jitter Buffer– This is software-based and configured by the network administrators.
8. Attempt Using a Different Device
If you are experiencing jitters on your wireless network, one solution you can try is attempting to use a different device. Jitters can sometimes be caused by problems with a specific device, such as a laptop or smartphone, rather than the wireless network itself. Using a different device can determine whether the problem is with the device or the network.
To attempt to use a different device, you will need to have another device available that can connect to the wireless network. For example, this could be a different laptop, smartphone, or tablet. Once a different device is available, try connecting to the wireless network and see if the jitter call quality persists.
If the jitter in the call does not occur when using a different device, the problem is likely with the original device and not the wireless network. If the jitters do not occur when using a different device, the problem is likely with the original device and not the wireless network. You may need to troubleshoot the issue with the original device to resolve the problem.
9. Change Wireless Network Source
If you are experiencing jitter in a voice call on your wireless network, one solution you can try is changing the source of the wireless network.
To change the wireless network source, you will need to access the settings on your device and look for an option to switch to a different wireless network. This could be a different router, a different access point, or a different wireless network altogether. You may also need to enter a password or other login credentials to connect to the new wireless network.
10. Restart Your Device
Restarting your device closes all open programs and processes, freeing up memory and processing power. However, this can resolve conflicts or bugs causing problems with your device’s performance. Restarting your device can also reset its network connections, which can help you experience connectivity issues.
To restart your device, power it off and turn it on again. This process will vary depending on your device, so you may need to refer to its user manual for specific instructions. In general, however, most devices can be restarted by pressing and holding the power button until the power off options appear on the screen and then selecting “restart.”
11. Reset Your Router
If you are experiencing jitter call quality or other performance issues while using the internet, resetting your router may be a solution. Resetting your router can resolve issues with its configuration or connection to your internet service provider (ISP). It can also help to resolve any conflicts or bugs that may be causing problems with your internet connection.
To reset your router, locate the reset button (usually located on the back) and hold it down for a few seconds until the router resets. However, be aware that resetting your router will erase any custom settings you have made, so you need to reconfigure the router after resetting it.
