Benefits of technology

[0006] The present invention mitigates or solves the above-identified limitations in known solutions, as well as other unspecified deficiencies in known solutions. A number of advantages associated with the present invention are readily evident to those skilled in the art, including economy of design and resources, transparent operation, cost savings, etc.

Problems solved by technology

Thus, while the VOX feature benefits from not requiring the user to manipulate a button to switch the communications device between the transmit and receive mode, the VOX feature typically fails to operate accurately or correctly in noisy environments as the VOX feature often inadvertently interprets loud noises as a voice signal and therefore needlessly places the communications device in transmit mode.
For one, the location of the PTT button often causes significant inconvenience to the user.

Abstract

Disclosed herein is a communications system implementing a microphone wirelessly connected to a half-duplex communications device, such as a two-way radio or a radio-simulating cellular phone. The microphone may incorporate a transmit / receive switch wherein a transmit signal is wirelessly transmitted from the microphone to the communications device to direct the communications device to enter into a transmit mode. The microphone may communicate with the half-duplex communications device through a magnetic induction link.
