CELL PHONE Russian patent published in 2023 - IPC H04M1/725 H04B11/00 H04W88/06 

FIELD: mobile wireless communication devices.

SUBSTANCE: invention relates to cell telephones with advanced technical capabilities that are capable of operating in the mode of receiving, emitting, relaying over one or two physical channels. The technical result is to ensure stable communication in the zone of unstable information exchange, reduce the total intensity of the electromagnetic field created by working mobile phones and reduce its impact on the user's body and others. To do this, a cell phone contains a receiver, a transmitter, a monitoring and control unit with permanent and random access memory, a keyboard, a display, a power supply, a voice communication unit, a voice activity detector, an encryption-decryption unit, analogue-to-digital (ADC) and digital-to-analogue (DAC) converters, a speech encoder and decoder, a channel encoder and decoder, and an equalizer interconnected via a system bus; in addition, the phone contains at least two subscriber identification modules connected through the controller to the system bus, and additionally contains at least two electronic subscriber identification modules that provide the implementation of acoustic communication channels, which are connected to the second controller via the system bus connected to the second control unit and control, equipped with permanent and random access memory, while an acoustic receiver with a receiving antenna and an acoustic transmitter with a transmitting antenna are also connected to the system bus.

EFFECT: ensuring stable communication in the zone of unstable information exchange, reducing the total intensity of the electromagnetic field created by working mobile phones and reducing its impact on the user's body and others
