Emergency Communication

University essay from Malmö högskola/Teknik och samhälle

Abstract: Even in the 21st century, modern communication technology is still affected by natural disasters and political turmoil which threaten people’s lives and make the internet or mobile phone networks unavailable for use. This work uses systems theory which resulted in a proof of concept system that uses shortwave radio technology to provide a one-way communication system. A message a user writes on their smartphone, which is connected to a small pre-set transmitter, is sent out to a receiver in another part of the world where the message can then be posted on the internet. This system is a cheaper alternative to other shortwave radio transmitters, and has potential for improvement.
