Mission-critical communications should focus bandwidth on content with effect

In mission-critical communications, the core focus is on communicating content with effecton operations. This introduces a few new approaches that has not been widely explored. The effect is achieved if information is received in time for being actionable – which is a time dependent on the situation in question, and a more relaxed definition than “real-time” generally is understood to be. Also, similar photos or video as already seen may not have as much additional effect on SA. These elements can be explored.

While Claude Shannon, inventor of modern information theory, wrote in 1948: “The semantic aspects of communication are irrelevant to the engineering problem”, his colleague at Bell Labs, Warren Weaver’s paper (Recent Contributions to The Mathematical Theory of Communication, 1949) observes that the effectiveness of a communications process could be measured by answering any of the following three questions

  1. COMMUNICATIONS: How accurately can symbols encoding a message be transmitted (“technical”)?
  2. CONTENT: How precisely do transmitted symbols convey the desired meaning (“semantics”)?
  3. IMPACT: How effective is the received message in changing conduct (“effectiveness “)?

While communication is an interactive exchange of messages among humans, communicationsis the technology used to achieve that goal. Weaver is noting that Shannon’s “information theory” concerns itself only with the answer to question A. Information networking for mission-critical operations fundamentally differs from e.g. traditional broadcast services for entertainment where full quality of visual and audio data is paramount. Instead, mission critical communications focus on information relevance and impact for operations, like in emergency and disaster management, security and safety operations. AnsuR has been targeting also the two other levels Weaver described.  We use “Response time”, rather than “Real time”. Information is needed in time to be able to respond to it. Often a few minutes delay is no problem, for instance in the context of flood, earthquake damages, forest fires, search and rescue, border patrol and more, while at other time a response may need shorter delays, like if controlling a plane (drone).
