FIELD: radio engineering, communication.
SUBSTANCE: NFC interrogation signal is transmitted at the predetermined intervals and performs, following each polling signal, the following actions: listening on the NFC response from the second wireless communication device, performing the data exchange with the second device, and if a response is received, transmitting the charging signal and stopping the charging signal transmission, as prescribed to occur to another NFC interrogation signal. Moreover, the NFC data exchange and the charging signal do not overlap in time.
EFFECT: providing the use of the same frequency band for both wireless communication and wireless charging by alternating two functions by dividing the time.
