DATA TRANSMISSION DEVICE, DATA TRANSMISSION METHOD, PROGRAMME AND DATA TRANSMISSION SYSTEM Russian patent published in 2014 - IPC H04B7/26 

FIELD: physics, computer engineering.

SUBSTANCE: invention relates to a near-field wireless data transmission system. An initiator according to the near field communication interface and protocol (NFCIP-1) transmits attribute information indicating the capacity to transmit data by the device itself, and also receives attribute information indicating the capacity to transmit data to a target from a target. When the received attribute information indicates that a target has power saving data transmission mode function, the initiator turns off electromagnetic wave output for a given period of time after data transmission.

EFFECT: reduced power consumption.
