Video conferencing has become an integral part of our modern digital world, revolutionising the way we communicate and collaborate. With the increasing popularity of remote work and virtual meetings, the demand for seamless video conferencing experiences is higher than ever before.
But have you ever wondered what makes a video call smooth and glitch-free? Two crucial factors—latency and bandwidth — play a significant role in determining the quality of your video conferencing experience.

In this article, we will unravel the mysteries behind latency and bandwidth and how they influence the quality of video communication over the Internet.
When it comes to computer networks, latency refers to the time delay that occurs when data packets travel from their source to their destination. Essentially, it’s the time it takes for a packet to travel across a network and reach its intended endpoint.
Latency is measured in units of time, typically milliseconds (ms) or microseconds (μs). These units provide a standardised way to quantify and compare latency values across different network environments.
Network latency is typically expressed in terms of round-trip time (RTT), which measures the time it takes for a packet to travel from the sender to the receiver and back. RTT is often used to assess latency for interactive applications, where responsiveness is critical.
Video latency refers to the delay between sending a video signal and displaying it on the screen. This latency can be caused by various factors, including the processing time of the video signal, network delays, and the buffering required to ensure smooth playback. High video latency can be particularly noticeable in live streaming and video conferencing, resulting in a noticeable lag between the speaker and the displayed video, affecting real-time communication and viewer experience.
Let’s have a look at some of the factors that affect latency.
Latency can be categorised into different types based on their specific characteristics and the impact they may have on network performance. Let’s have a look at some of the most common types:
Latency has a significant impact on network performance and user experience:
Higher latency results in slower response times, frustrating users and reducing productivity. Delays in loading web pages or interacting with applications diminish the overall user experience.
Latency disrupts real-time applications such as video conferencing, online gaming, and live streaming. Even minor delays in these industries can cause communication disruptions, lag, financial losses or compromised interactions.
Latency affects remote collaborations and video conferencing by introducing noticeable delays in conversations, hindering the natural flow and effective collaboration that users are used to in face-to-face communication.
In financial trading, low latency is crucial for executing trades quickly and accurately. Even milliseconds of delay can lead to missed opportunities and financial losses in the millions or billions of dollars.
Bandwidth refers to the maximum data transfer rate of a network or internet connection. In simpler terms, you can think of bandwidth as the maximum capacity or amount of data that can be transmitted through a network at a particular time. Think of your
It is measured in bits per second (bps), with higher units like kilobits per second (Kbps) and megabits per second (Mbps) representing larger capacities. Bandwidth determines the speed at which data can be transmitted over a network.
Like latency, there are also a few factors that can affect bandwidth.
Having good bandwidth is crucial for a seamless digital experience. It enables faster downloads, smooth streaming, and responsive online interactions. Adequate bandwidth supports multiple users without significant performance degradation or network congestion.
Low bandwidth, on the other hand, has negative impacts. This includes slower data transfer speeds, buffering during media streaming, and delays in webpage loading. Real-time applications suffer from poor quality, lag, and disrupted interactions with low bandwidth.
Latency and bandwidth are two critical aspects of network performance, each playing a distinct role in data transmission. While related, it is essential to grasp the differences between latency and bandwidth to optimise network performance effectively.
As mentioned above, latency, also known as delay, is the time it takes for data packets to travel from the source to the destination. It represents the overall time delay experienced during the transmission process. Latency is influenced by several factors within the network infrastructure.
Latency is typically measured in units of time, typically milliseconds (ms) or microseconds (μs) and expressed in terms of round-trip time (RTT).
Bandwidth, on the other hand, refers to a network's capacity to transmit data within a specific timeframe. It quantifies the maximum amount of data that can be transmitted over the network.
Bandwidth is typically measured in bits per second (bps) or its derivatives, such as kilobits per second (Kbps) or megabits per second (Mbps).
Latency and bandwidth address different aspects of network performance, and it is important to understand their distinctions:
Understanding the practical implications of latency and bandwidth can help illustrate their significance in different scenarios:
Achieving optimal network performance requires finding the right balance between latency and bandwidth. Both factors need to be carefully considered and optimised:
Understanding the distinctions between latency and bandwidth is crucial for effectively managing and optimising network performance. Achieving the right balance ensures a responsive and efficient network environment.
