CELLPHONE Russian patent published in 2020 - IPC H04W88/06 

FIELD: wireless communication equipment.

SUBSTANCE: invention relates to devices intended for wireless communication networks, specifically to a terminal, intended for operation in multiple communication networks. To achieve technical result, a cellphone placed in a housing and equipped with four antennae has two receiver units and two transmitter units interconnected by means of the system bus, a control and monitoring unit with permanent and random-access memory, two controllers, a keyboard, a display, three power supply units, two of which are configured to monitor, control and recharge, a voice communication unit, voice activity detector, an encryption-decryption unit, analogue-to-digital and digital-to-analogue converters, speech encoder and decoder, channel encoder and decoder, an equalizer, as well as two units, each of which combines at least two modules of subscriber identification, by means of controllers and system bus connected to control and monitoring unit. First antenna is connected to first receiver unit, which is connected to second antenna through first transmitter unit, powered from second power supply unit, wherein the third antenna interacts with the second transmitter unit, which is powered from the third power supply unit and is connected to the monitoring and control unit by means of the system bus; fourth antenna interacts with the second receiver unit, which is connected to the control and monitoring unit through the system bus.

EFFECT: high reliability of delivering information while increasing transmission speed thereof and high stealthiness by dividing content into parts and delivering the subscriber in parts through different cellular operators to obtain information over parallel channels, neutralization and reduced impact on quality of delivery of various harmful factors, including failure of base station of one of cellular operators, due to simultaneous use of several different operators.
