Abstract

A multivoice radio system allows users to speak and listen, at the same time, to others using multivoice radios without using a base station. Several embodiments of the present invention are directed toward combining a multivoice radio with push-to-talk (PTT), long-range radio. Other embodiments combine two or more multivoice systems and/or use an extender to increase a distance that multivoice radios can communicate with each other. Combining multivoice systems, in some embodiments, creates a voice and/or data mesh network. Switch-to-talk (STT) functionality can be added to systems to increase a number of users and promote radio discipline. Additionally, a combined in-ear microphone and speaker is disclosed. Further embodiments are directed to combining duplex radios, such as mobile phones, to multivoice systems, and/or PTT systems.

The two-way radio system for combining a short-range, handheld radio that is part of a wireless conferencing system using time-division multiplexing, without using a base station, with a long-range, handheld radio as recited in claim 1, wherein the signal compounder is in a separate housing from the first radio and from the second radio.

4. The two-way radio system for combining a short-range, handheld radio that is part of a wireless conferencing system using time-division multiplexing, without using a base station, with a long-range, handheld radio as recited in claim 1, wherein:

the second radio is a half-duplex radio, and

the fifth radio is a half-duplex radio.

5. The two-way radio system for combining a short-range, handheld radio that is part of a wireless conferencing system using time-division multiplexing, without using a base station, with a long-range, handheld radio as recited in claim 1, wherein the first radio, the third, and the fourth radio are duplex radios, such that a user of either the first radio, the third, or the fourth radio can speak to other users and listen to radio communication simultaneously on the first frequency band.

6. The two-way radio system for combining a short-range, handheld radio that is part of a wireless conferencing system using time-division multiplexing, without using a base station, with a long-range, handheld radio as recited in claim 1, wherein the first transmitter and the first receiver are combined as a transceiver.

7. The two-way radio system for combining a short-range, handheld radio that is part of a wireless conferencing system using time-division multiplexing, without using a base station, with a long-range, handheld radio as recited in claim 1, wherein the signal compounder further comprises circuitry that:

combines the first signal and the second signal to create a first combined signal; and

sends, through the third connection, the first combined signal to the speaker.

8. A method for combining a short-range radio conferencing system with a long-range radio, the method comprising:

the first radio, the third radio, and the fifth radio are configured to communicate with each other without using a base station;

receiving a second signal from a second radio, wherein;

the second radio is not the first radio, and

the second radio operates in a second frequency band to transmit and receive wireless communication to and from a fourth radio;

receiving a third signal from a microphone, wherein the microphone is separate from the first radio and the second radio;

sending the third signal to the first radio for transmission on the first frequency band; and
