'Mission possible': A low-cost alarm system for public safety 800MHz communications

摘要

The assignment is the needs assessment, preliminary design, and project management of a large public safety communications project. The system is a state-of-the-art 800MHz trunked simulcast network consisting of four sites that are interconnected with digital microwave. Additionally, a four-site, two-chan- nel, conventional mobile data system shares the same locations as the trunked voice system.
