Abstract
A two-way radio system is claimed. The two-way radio system comprises a plurality of handheld radios. Each handheld radio has a housing and a receiving means and a transmitting means. The handheld radios function over a fixed frequency range. Each radio also includes a method of announcing an incoming call sent from a first handheld radio to a second handheld radio. The method comprises the steps of transmitting a communication within the fixed frequency range from the first handheld radio. The transmission is received by the second handheld radio, and announced by producing a vibrational movement in the housing of the second handheld radio.
Claims9
In a two-way radio system of a type comprising at least a first and second two-way handheld walkie-talkie radio, a method of announcing an incoming call sent from the first two-way bandheld walkie-talkie radio to the second two-way handheld walkie-talkie radio, comprising the steps of:
- providing a first two-way handheld walkie-talkie radio and a second two-way handheld walkie-talkie, each two-way handheld walkie-talkie having a housing, a transmitting means for transmitting a call announcement signal and a separate voice signal, said voice signal being different from said announcement signal and being transmitted over a fixed frequency range, a receiving means for receiving the voice communication signal and call announcement signal and announcing the call announcement signal and means for selectively choosing between an audible call announcement or a vibrational call announcement, wherein the first and second two-way handheld walkie-talkie do not communicate one to the other through a base station;
- choosing the vibrational call announcement on the second two-way handheld radio;
- transmitting the voice communication signal within the fixed frequency range from the first two-way handheld walkie-talkie radio;
- receiving the voice communication signal with the second two-way handheld walkie-talkie radio;
- transmitting the call announcement signal from the first two-way handheld walkie-talkie radio;
- and,
- announcing the call announcement signal in the second two-way handheld walkie-talkie radio by producing a vibrational movement in the housing of the second two-way handheld walkie-talkie radio, said vibrational movement being responsive to said call announcement signal.
