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.

2. Terrestrial Trunked Radio (Tetra) Public Safety Networks

In the UK the TETRA system forms part of the UK government’s strategic Critical National Infrastructure policy; this was developed after the 2001 terrorist incidents to provide a comprehensive solution to combat terrorist attacks on the countries electronic communications infrastructure. These new emergency services communications platforms are generally called Public Safety Networks and their initial objective is to achieve signal coverage across a country, homogenising the regional communications of that country, between the ambulance services, police services and the fire brigade. These systems are digital radio systems that are a vast improvement on the old analogue radio networks previously used by the emergency services.
