Network Standards in Public Safety 

APCO & Tetra Standards: We would like to mention two emerging public safety network standards. The first standard, called APCO 25 (Associated Public Safety Communications Officials), has finally emerged after many years of work and is being promoted by police organizations throughout North America. Vendors like Motorola, E.F.Johnson and Ericsson have all announced product plans for the standard. The second standard, established in Europe, is called TETRA (Trans European Trunked Radio or Terrestrial Trunked Radio)).
