Data processor, relay transmitter, and data transmission system

A relay transmitter comprising:

• a first communication unit configured to perform wireless communication with an data processor;
• a second communication unit configured to perform data communication with an external device;
• a storage unit configured to store a first physical address for the data processor;
• an address receiver configured to, in response to the relay transmitter being turned on, receive, from the data processor, a second physical address for the data processor along with an instruction to start authentication between the data processor and the relay transmitter;
• a determining unit configured to, in response to the instruction from the data processor, make a determination as to whether the second physical address for the data processor is identical to the first physical address for the data processor;
• and
• a connecting unit configured to, when one or more authentication requirements are satisfied, transmit a physical address for the relay transmitter to the data processor and establish wireless connection between the first communication unit and the data processor so as to achieve data communication between the data processor and the external device via the relay transmitter, the authentication requirements including the determination by the determining unit that the second physical address for the data processor is identical to the first physical address for the data processor.

A data transmission system comprising:

• a relay transmitter configured to perform data communication with an external device;
• and
• an data processor configured to perform data communication with the external device via wireless communication with the relay transmitter,
• wherein the data processor comprises:
• a communication unit configured to perform wireless communication with the relay transmitter;
• a storage unit configured to store a first physical address for the relay transmitter;
• an authentication starter configured to, in response to the data processor being turned on, transmit, to the relay transmitter, an instruction to start authentication between the data processor and the relay transmitter along with a physical address for the data processor;
• an address receiver configured to receive a second physical address for the relay transmitter from the relay transmitter as a response to the instruction;
• a determining unit configured to make a determination as to whether the second physical address for the relay transmitter is identical to the first physical address for the relay transmitter;
• and
• a connecting unit configured to, when one or more authentication requirements are satisfied, establish wireless connection between the communication unit and the relay transmitter so as to achieve the data communication between the data processor and the external device via the relay transmitter, the authentication requirements including the determination by the determining unit that the second physical address for the relay transmitter is identical to the first physical address for the relay transmitter, and
• wherein the relay transmitter comprises:
• a first relay-transmitter-side communication unit configured to perform wireless communication with the data processor;
• a second relay-transmitter-side communication unit configured to perform data communication with the external device;
• a relay-transmitter-side storage unit configured to store a first physical address for the data processor;
• a relay-transmitter-side address receiver configured to, in response to the relay transmitter being turned on, receive, from the data processor, a second physical address for the data processor along with the instruction to start authentication between the data processor and the relay transmitter;
• a relay-transmitter-side determining unit configured to, in response to the instruction from the data processor, make a determination as to whether the second physical address for the data processor is identical to the first physical address for the data processor;
• and
• a relay-transmitter-side connecting unit configured to, when the authentication requirements are satisfied, transmit a physical address for the relay transmitter to the data processor and establish wireless connection between the first communication unit and the data processor so as to achieve the data communication between the data processor and the external device via the relay transmitter, the authentication requirements including the determination by the relay-transmitter-side determining unit that the second physical address for the data processor is identical to the first physical address for the data processor.
