White Paper

Under the Hood: Coverage theory for Public Safety networks - a System Engineer's view

This white paper provides network operators some insight into how a System Engineer can design for network coverage that meets specific requirements. It addresses three basic techniques, which, used individually or in combination, can overcome geographical or urbanization influences, to increase coverage reliability. While this paper is especially relevant for the critical coverage requirements of Public Safety operators, the principles described are equally applicable for other sectors.
