Oklahoma Operating Police Frequency radio is a type of radio communication system used by law enforcement in the state of Oklahoma. It is a two-way radio system that allows police officers to communicate with each other while on patrol. The system includes a base station located at police headquarters, a mobile station in the patrol car, and a handheld unit for remote communication. There are two types of Oklahoma Operating Police Frequency radios: VHF (Very High Frequency) and UHF (Ultra High Frequency). VHF frequencies are typically used for long-range communication between police departments and are more difficult to intercept. UHF frequencies are used for short-range communication and are easier to intercept. Both types of radios are used to transmit voice, data, and images.
