Abstract

An electronic communication device includes a high-rate RF wireless transmitter circuit (e.g., a TransferJet transmitter circuit) and a low-rate magnetically coupled receiver circuit (e.g., a Near Field Communication receiver circuit). The high-rate RF wireless transmitter circuit transmits a block of data to another proximately located communication device via RF signals using a first RF communication protocol. The low-rate magnetically coupled receiver circuit receives a communication control signal from the other proximately located communication device via magnetic coupling thereto using a second protocol that is different from the first RF communication protocol, and responds to the communication control signal by selectively triggering the high-rate RF wireless transmitter circuit to transmit another block of data when available for transmission.
