Abstract

A communication method in a wireless communication system includes receiving, by a resonator unit of a first signal transfer apparatus, a wireless signal transmitted from a transmission apparatus, acquiring resonance energy from the wireless signal using at least one of a matcher unit and the resonator unit of the first signal transfer apparatus, transferring the wireless signal to one end of a transmission line via the matcher unit of the first signal transfer apparatus using the acquired resonance energy, transferring the wireless signal to a second signal transfer apparatus connected to an opposite end of the transmission line, and transmitting the wireless signal to a reception apparatus having a wireless link established with the second signal transfer apparatus using a matcher unit and a resonator unit of the second signal transfer apparatus.

First claim

What is claimed is:

1. A wireless communication method using a transmission line, the wireless communication method comprising:
receiving, by a resonator unit of a first signal transfer apparatus, a wireless signal transmitted from a transmission apparatus;
acquiring resonance energy from the wireless signal using at least one of a matcher unit and the resonator unit of the first signal transfer apparatus;
transferring the wireless signal to one end of the transmission line via the matcher unit of the first signal transfer apparatus using the acquired resonance energy;
transferring the wireless signal to a second signal transfer apparatus connected to an opposite end of the transmission line; and
transmitting the wireless signal to a reception apparatus having a wireless link established with the second signal transfer apparatus using a matcher unit and a resonator unit of the second signal transfer apparatus.

2. The wireless communication method of claim 1 , wherein the first signal transfer apparatus is connected to the one end of the transmission line using a first connector, and the second signal transfer apparatus is connected to the opposite end of the transmission line using a second connector.

3. The wireless communication method of claim 2 , further comprising:
transferring the wireless signal to the one end of a transmission line that is connected to the second connector through an expansion connector connected to the second connector;
transferring the wireless signal to the opposite end of the transmission line that is connected through the expansion connector;
transferring the wireless signal to a third signal transfer apparatus that is connected to the opposite end of the transmission line that is connected through the expansion connector; and
transmitting the wireless signal to the reception apparatus having a link established with the third signal transfer apparatus using at least one of a matcher unit and a resonator unit of the third signal transfer apparatus.

4. The wireless communication method of claim 3 , wherein the opposite end of the transmission line connected through the expansion connector is connected to the third signal transfer apparatus through a third connector.

5. The wireless communication method of claim 3 , wherein the transmission apparatus having a wireless link established with the first signal transfer apparatus and the reception apparatus having the wireless link established with the second signal transfer apparatus and the third signal transfer apparatus are provided as a communication terminal or a desk type communication apparatus.

6. The wireless communication method of claim 3 , wherein the first signal transfer apparatus, the second signal transfer apparatus, and the third signal transfer apparatus are replaceable according to a communication scheme with the transmission apparatus and/or the reception apparatus having the wireless link established with the first signal transfer apparatus, the second signal transfer apparatus, and the third signal transfer apparatus.

7. The wireless communication method of claim 3 , wherein the resonator unit of each of the first signal transfer apparatus, the second signal transfer apparatus, and the third signal transfer apparatus includes an antenna.

8. The wireless communication method of claim 3 , wherein the matcher unit of each of the first signal transfer apparatus, the second signal transfer apparatus, and the third signal transfer apparatus performs impedance matching, and includes at least one of a balun and a transformer.

9. A wireless communication apparatus using a transmission line, the wireless communication apparatus comprising:
a first signal transfer apparatus configured to receive a wireless signal from a transmission apparatus having a wireless link established with the first signal transfer apparatus and acquire resonance energy;
a second signal transfer apparatus configured to transmit the wireless signal to a reception apparatus having a wireless link established with the second signal transfer apparatus using the acquired resonance energy; and
a transmission line coated with a flame-retardant material and configured to transfer the wireless signal from the first signal transfer apparatus to the second signal transfer apparatus using the acquired resonance energy,
wherein the first signal transfer apparatus is connected to one end of the transmission line, and the second signal transfer apparatus is connected to an opposite end of the transmission line.

10. The wireless communication apparatus of claim 9 , wherein the first signal transfer apparatus is connected to the one end of the transmission line using a first connector, and the second signal transfer apparatus is connected to the opposite end of the transmission line using a second connector.

11. The wireless communication apparatus of claim 10 , wherein the second connector is connected to and separated from an expansion connector.

12. The wireless communication apparatus of claim 11 , further comprising a third signal transfer apparatus connected to the opposite end of a transmission line that is connected to the expansion connector, wherein the third signal transfer apparatus has a wireless link established with a reception apparatus that is the same as or different from the reception apparatus.

13. The wireless communication apparatus of claim 12 , wherein the opposite end of the transmission line connected to the third signal transfer apparatus through the expansion connector is connected to the third signal transfer apparatus through a third connector.

14. The wireless communication apparatus of claim 12 , wherein the transmission apparatus having the wireless link established with the first signal transfer apparatus and the reception apparatus having the wireless link established with the second signal transfer apparatus and the third signal transfer apparatus are provided as a communication terminal or a desk type communication apparatus.

15. The wireless communication apparatus of claim 12 , wherein the first signal transfer apparatus, the second signal transfer apparatus, and the third signal transfer apparatus are replaceable according to a communication scheme with the transmission apparatus and/or the reception apparatus having the wireless link established with the first signal transfer apparatus, the second signal transfer apparatus, and the third signal transfer apparatus.
