Краткое описание:
Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. Project 25 (P25) or APCO-25 refer to a suite of standards for digital radio communications for use by federal, state/province and local public safety agencies in North America to enable them to communicate with other agencies and mutual aid response teams in emergencies. In this regard, P25 fills the same role as the European Tetra protocol, although not interoperable with it.Public safety radios were upgraded from analog to digital decades ago owing to the several limitations that analogs posed and also because technological advancements provided wireless, shared systems that in turn provided enhanced communication services critical to first responders. Therefore, in the late 1970s a functional specification called Project 16 (P16) was developed for Public Safety trunked systems by the Association of Public Safety Communications Officials International (APCO) to include definitions for Public Safety radio communications analog with voice, and radio channel trunking using the newly-allocated 800 MHz frequency band.
