Real-time communications (RTC) are the near simultaneous exchange of information over any type of telecommunications service from the sender to the receiver in a connection with negligible latency, according to Search Unified Communications. Examples of real-time communications include:

  • Voice over landlines and mobile phones
  • VoIP
  • Instant messaging (e.g., WhatsApp, WeChat, Facebook Messenger)
  • Video and teleconferencing
  • Robotic telepresence

Real-time communications can take place in half-duplex or full-duplex modes:

  • Half-duplex RTC. Data transmission can happen in both directions on a single carrier or circuit but not at the same time.
  • Full-duplex RTC. Data transmission can occur in both directions simultaneously on a single carrier or circuit.
