A University of Sussex doctoral student finalized a thesis conducting new research in rapid deployment of a national public security and emergency communications network using communications satellite broadband.

“Although studies in public security communication networks have examined the use of communications satellite as an integral part of the communication infrastructure, there has not been an in-depth design analysis of an optimized regional broadband-based communication satellite in relation to the envisaged service coverage area, with little or no terrestrial last-mile telecommunications infrastructure for delivery of satellite solutions, applications and services,” the university said online. “As such, the research provides a case study of a Nigerian public-safety security communications pilot project deployed in regions of the African continent with inadequate terrestrial last-mile infrastructure and thus requiring a robust regional communications satellite complemented with variants of terrestrial wireless technologies to bridge the digital hiatus as a short and medium term measure apart from other strategic needs.”

The research addresses the pivotal role of a secured integrated communications public-safety network for security agencies and emergency service organizations with its potential to foster efficient information symmetry among their operations including during emergency and crisis management in a timely manner but demonstrates a working model of how analog spectrum meant for push-to-talk (PTT) services can be refarmed and digitalized as a “dedicated” broadband-based public communications system.

The network’s sustainability can be secured by using excess capacity for the strategic commercial telecommunication needs of the state and its citizens. Use of scarce spectrum has been deployed for Nigeria’s cashless policy pilot project for financial and digital inclusion. This effectively drives the universal access goals, without exclusivity, in a continent, which still remains the least wired in the world.
