Two-Way Police Radio Communication, 1933
Bayonne, NJ Dedicated May 1987 - IEEE North Jersey Section
In 1933, the police department in Bayonne, New Jersey initiated regular two-way communications with its patrol cars, a major advance over previous one-way systems.
The Bayonne system was developed less than five years after the deployment of the one-way AM mobile-radio system by the Detroit Police Department. On April 7, 1928, the Detroit Police commenced regular one-way radio communication with its patrol cars. This system proved the practicality of land-mobile radio for police work and led to its adoption throughout the county.
