Abstract

In developed economies, electronic communication infrastructures are crucial for daily public, private, and business interactions. Cellular systems are extensively used for business communications, private interaction, and in some cases, public information services, via such uses as mass SMS messaging. The Public Switched Telephone Network PSTN is at the core of all communications platforms. It was used primarily for voice communication purposes, but with current technological advances, this platform has been transformed from a voice to voice interface to a web enabled multimedia platform that provides commercial, business, and e-commerce services to the public. In response to the September 11, 2001, terrorist acts in New York City, the UK government introduced a policy of separating and transferring all emergency communication traffic from the PSTN to a digital public safety network based on the TETRA architecture. This paper extends the utilisation of the TETRA deployment by discussing a secure MANET hybrid solution for use in extreme situations as a short/mid-term EMS organisational communication platform for emergency and rescue operations.
