Types of Real-time Communication and their Use Cases ---- 6 min read

There was a phase in human history when putting ink on paper and sending it out through a carrier was the only means to communicate a message. Can you imagine negotiating a business transaction through this slow means of communication? 

Well, somehow, it was done for centuries.

Then came the telegraph, and then the telephone. Then, finally, we entered the era of Real-Time Communication.

What is real-time communication?

Real-time communication refers to any online communication that offers exchange of information between a sender and a receiver in real-time. It occurs with minimal latency in such a way that both parties are present simultaneously and are communicating remotely.

For varied types of Web and Mobile applications, real-time communication can be an important factor for growth. They can be of the following types: 

  • Video & Voice Call
  • Live Broadcast
  • Pub/Sub events
  • Chat

In today’s era where information must be shared quickly, decisions must be made promptly, products have to be developed rapidly, and customer queries have to be solved right away, the advantages of real-time communications are countless. Be it Healthcare, Dating and Matrimonial, Education, E-Commerce, or On-demand business, adopting real-time communication is a great way to set the foundation of engaging interactions and efficient operations.

Let us dig deeper to know the types of real-time communication and how different businesses are leveraging these.

Types of Real-time Communication

Video and Voice Call

Voice and video calls offer almost in-person interaction experience, irrespective of distance, and benefit in personalizing sessions between users.

For instance, 

  • A teacher delivering online lessons via video conferencing 
  • A yoga teacher conducting a face-to-face Yoga session
  • Participants in a Group Therapy Session
  • A consultant giving advisory to her customer

Voice and Video calls can be further divided into:

  • One-to-one call
  • Group call

Whether your app offers customer support, advisory services, healthcare, dating, or concierge services, a video call adds personal touch to interactions that drives engagement and customer retention while ensuring the confidentiality of communication. It helps your users offer better services, and become more efficient.

Live Broadcast

Live streaming is an engaging medium that grabs audience’s attention and allows businesses to deliver compelling and engaging content and forge a strong brand connection.

For instance, 

  • Product demonstration hosted by an influencer
  • A live virtual event, or online event
  • An online concert

The widespread use of live streaming is changing the face of many industries today, including retail and commerce, events, entertainment and sports. 

A live broadcast can be classified into 

  • Single host broadcast: 1 to many communication 
  • Multiple host broadcast: Many to many communication

Live Broadcast experiences are further enhanced by features like open chat conversations, real-time polls, quizzes and trivias and so on.

Real-time Pub/Sub events

Pub/Sub messaging is a concept whereby a communication channel is set up between a server and its clients and both the parties are notified in real-time about occurence of events. They are leveraged by various app types for real-time updates and real-time interactivity.

Some example use-cases:

  • Whether to book a cab or to track order status, applications like these must be updated without requiring any action from the user. 
  • To optimize delivery, dispatching systems need up-to-date information on where their drivers are. Pub/sub-event messaging helps logistics companies do this.
  • In Online Events, a host may mute / unmute participants, or start a new poll

All these are made possible by implementing Pub/Sub messaging patterns into your platform.


Chat is a powerful proactive communication feature that enables your website and app users to chat in real-time. 

In today’s era, users expect real-time responsiveness that provides them with what they want and right when they want it. Hence real-time chat has become synonymous to speed and convenience that connects people without the need to dial a number or to wait on hold on a call. 

For instance, 

  • Initiation of chat between a doctor and patient after an appointment is booked
  • A customer sharing his or her location with a service provider via chat
  • Two dating prospects chatting with each other
  • Parent to teacher Chat in a School’s App
  • Group Chat in an interest based network app
  • Open Chat in an online event

Chat can be classified into:

  • One-to-One Chat
  • Many-to-Many or Group Chat
  • Open Conversations

Further, these real-time chat conversations can be made more interactive by using features like Online Presence and Typing Indicators, Media Sharing, Push Notifications, etc. They can also be made secure using End-to-End encryption.

Using a Chat Plugin for popular CMS platforms like WordPress can help websites adopt real-time communication quickly and effortlessly. Chat plugin for WordPress lets your users communicate while they are using the website.
