Recent events have shown that in the aftermath of an emergency, disaster or any related tremendous unexpected events, a reliable communication infrastructure plays an important role in providing critical services including emergency recovery operations, critical infrastructure restoration, post-disaster surveillance etc. In most of the cases, immediately after a large scale disaster, the normal terrestrial network infrastructure is seriously compromised and cannot guarantee reliable and large scale coverage for rescue teams and citizens. Current mission critical communication systems including PPDR (Public Protection for Disaster Relief) systems are heavily limited in terms of network capacity and coverage. They are not designed for or suitable to address large scale emergency communication deployments immediately after the disaster scenarios where these networks can provide dependable and resilient network connectivity at higher data rates over large coverage areas. Moreover, PPDR systems are limited by interoperability barriers and the technological gap with commercial technologies and evolving standards.
Furthermore, the first responder devices and terminals are getting smarter with new applications supporting packet data with integrated sensors and other monitoring and the availability of multimode heterogeneous embedded receivers. Such improvements call for a marked increase in capacity and energy demands for the first responder (FR) user terminals. Further, there is a large demand in the PPDR community for higher bandwidth emergency communication infrastructure to cater for the new mission critical services with very high throughput and low-delay requirements during the immediate post-emergency period (including real-time video streaming and video surveillance, exchange of high resolution pictures etc). Also some foreseen/unforeseen events with large aggregation of professional and consumer users such as e.g. big sport events, road shows or concerts require high capacity and/or dedicated coverage that the legacy terrestrial network infrastructure cannot provide rapidly.
These factors underline an urgent requirement for a rapidly deployable multi-purpose, multi service and multi-band interoperable and integrated network infrastructure capable of supporting reliable high data rate applications to serve large scale disaster emergency situations and the temporary event scenarios.
