Participants can join a web conference through their computers or mobile devices using an internet connection. Web conferencing is versatile and can be used for presentations, demonstrations, collaborative work, or even social events.
  4. Audio-Web Conferencing: This is a blend of audio conferencing and web conferencing, where participants join a meeting via a regular phone line, but visual content like presentations or documents are shared through an internet connection.
  5. Teleseminars: Teleseminars or teleclasses are typically conducted over a telephone line or through an internet audio service, where a speaker delivers a lecture or workshop to a group of participants. Although primarily audio-based, some teleseminars might incorporate an online visual component.
  6. Videoconferencing Telepresence: This is an immersive form of video conferencing that aims to replicate in-person meetings as closely as possible. Large, high-definition screens display life-sized images of participants, and high-quality audio systems capture and transmit sound, giving a sense of "being there" without having to travel.
  7. Webinars: A webinar, or web-based seminar, is a type of web conferencing primarily used for conducting presentations and workshops over the internet. A key feature of webinars is their interactive elements – the ability to give, receive and discuss information.

Each of these types serves different purposes and is used in different contexts, depending on the communication requirements, resources available, and the level of interaction needed.

How does teleconferencing work?

Teleconferencing, whether audio, video, or web-based, involves the use of certain technology to transmit and receive data in real-time. Here's a basic breakdown of how teleconferencing works:

  1. Transmission: The first step in a teleconference is the transmission of data. Participants connect to a teleconferencing platform using an internet-connected device, like a computer, smartphone, or specialized video conferencing equipment. When a participant speaks or moves, the audio and video information is captured by their device's microphone and camera.
  2. Compression: This data is then compressed using a codec (coder-decoder). The role of the codec is to shrink the audio and video data to a manageable size so that it can be transmitted efficiently over the network.
  3. Distribution: The compressed data is then sent over the internet or a dedicated network to a central system known as a Multipoint Control Unit (MCU) or a similar system in the case of cloud-based services. The MCU is responsible for routing the data to all other connected devices in the teleconference. This ensures that each participant can see and hear all the other participants.
  4. Decompression: Once the data arrives at each participant's device, it is decompressed back into audio and video signals. This process happens in real-time and is virtually unnoticeable, which gives the impression of a live conversation.
  5. Display: The decompressed data is then displayed on the participant's screen and played through their speakers.

Teleconferencing platforms also offer additional features to facilitate better communication. These can include text chat, instant messaging, file sharing, screen sharing, virtual backgrounds, and more.

It's important to note that the quality and smoothness of a a teleconference call can be affected by several factors, including the speed and reliability of the internet connection, the power of the device being used, the quality of the camera and microphone, and the capacity of the teleconferencing platform.

Audio teleconferencing

Audio teleconferencing, sometimes simply referred to as a virtual conferencing or a conference call, is one of the earliest forms of teleconferencing. It is a communication method that allows a group of people in different locations to interact simultaneously through voice-based calls.

This type of teleconferencing call recording can be performed through traditional landline telephones, mobile phones, or via computer-based applications that use Voice over IP (VoIP) technology, such as Skype or Google Hangouts. VoIP technology transmits audio signals over the internet rather than through traditional phone lines.

To initiate an audio teleconference, a host dials an access code into the service first and then each participant dials a specific phone number at a set time and inputs a unique code to join the conference call. In more advanced systems, the service may dial out to participants at the scheduled time.

Advantages of Audio Teleconferencing

  1. Simplicity: Audio teleconferencing is typically straightforward and easy to use. Participants need no more than a phone or a device with internet access.
  2. Accessibility: As long as individuals have a phone or an internet connection, they can participate in an audio conference. This makes it an accessible option for people who might not have access to a computer or video equipment.
  3. Less Bandwidth: Audio teleconferencing uses significantly less bandwidth compared to video teleconferencing, reducing the chances of connection issues or call lag.

Disadvantages of Audio Teleconferencing

  1. Lack of Visuals: Without the visual component, participants miss out on non-verbal cues that often aid in communication. Misunderstandings may occur as a result.
  2. Background Noise: Audio calls can be disrupted by background noise from each participant's location. If someone forgets to mute their microphone, noise can interfere with the meeting.
  3. Participant Identification: In large audio conferences, it can be difficult to identify who is speaking at any given time, which can lead to confusion.

Video teleconferencing

Video teleconferencing, often simply referred to as video conferencing, is a technology that allows individuals or groups of people located in different places to interact with each other using both audio and video components. It facilitates a more immersive and interactive communication experience compared to audio-only teleconferencing, by enabling participants to see each other in real time.

To participate in a video conference, each participant needs a device with a camera and microphone (like a computer, tablet, or smartphone), a stable internet connection, and access to the video conferencing platform or software the mobile device is being used.

Video teleconferencing is powered by complex technology, but the basic steps are as follows:

  1. Audio and video data is captured from each participant's device.
  2. The data is compressed to a manageable size using a codec (coder-decoder).
  3. The compressed data is sent over the internet to all the other connected devices in the conference.
  4. The data is decompressed at each device and the audio/video signals are played in real-time.

Video teleconferencing is used in various settings, including business meetings, academic lectures, medical consultations online meetings, and social gatherings.
