Abstract

A wireless communications system includes a tool having a first wireless communications unit and a transceiver having a second wireless communications unit to receive a signal transmitted from the first wireless communications unit. Further, the transceiver has a setting unit for setting wireless communications parameters for wireless communications between the first and the second wireless communications unit, and the tool has a tool control unit for setting in the wireless communications unit the wireless communications parameters set by the setting unit and transmitted to the tool by wireless communication.

Claims

1. A wireless communications system comprising:

a tool having a first wireless communications unit; and

a transceiver having a second wireless communications unit to receive a signal transmitted from the first wireless communications unit,

wherein the transceiver has a setting unit for setting wireless communications parameters for wireless communications between the first and the second wireless communications unit, and

the tool has a tool control unit for setting in the first wireless communications unit the wireless communications parameters set by the setting unit and transmitted to the tool by wireless communication

wherein the wireless communications parameters include at least one of a usable transmission frequency, a transmission output power and the number of retransmissions.

2. The system of claim 1, wherein a dedicated frequency is used to transmit the wireless communications parameters.

3. The system of claim 1, wherein the wireless communications parameters are transmitted at a transmission output power lower than that of normal communications.

4. The system of claim 1, wherein the transceiver communicates with a plurality of tools having their respective identification numbers.

5. The system of claim 1, wherein the usable transmission frequency is a frequency to be used to transmit an operation completion signal, the transmission output power is for transmitting the operation completion signal and the number of retransmissions is the number of transmissions of the operation completion signal to the transceiver.

6. The system of claim 1, wherein the wireless communications parameters include a usable transmission frequency, a transmission output power and the number of retransmissions.

7. The system of claim 6, wherein the usable transmission frequency is a frequency to be used to transmit an operation completion signal, the transmission output power is for transmitting the operation completion signal and the number of retransmissions is the number of transmissions of the operation completion signal to the transceiver.

8. The system of claim 1, wherein the wireless communications parameters include a usable transmission frequency, a transmission output power and the number of retransmissions.

9. The system of claim 8, wherein the usable transmission frequency is a frequency to be used to transmit an operation completion signal, the transmission output power is for transmitting the operation completion signal and the number of retransmissions is the number of transmissions of the operation completion signal to the transceiver.

10. A wireless communications system comprising:

a tool having a first wireless communications unit; and

a transceiver having a second wireless communications unit to receive a signal transmitted from the first wireless communications unit,

wherein the tool has a setting unit for setting wireless communications parameters for wireless communications between the first and the second wireless communications unit,

the setting unit is a remote controller for the tool, and

the transceiver has a transceiver control unit for setting in the second wireless communications unit the wireless communications parameters set by the setting unit and transmitted to the transceiver by wireless communications

wherein the wireless communications parameters include at least one of a usable transmission frequency, a transmission output power and the number of retransmissions.

11. The system of claim 10, wherein a dedicated frequency is used to transmit the wireless communications parameters.

12. The system of claim 10, wherein the wireless communications parameters are transmitted at a transmission output power lower than that of normal communications.

13. The system of claim 10, wherein the transceiver communicates with a plurality of tools having their respective identification numbers.

14. The system of claim 10, wherein the usable transmission frequency is a frequency to be used to transmit an operation completion signal, the transmission output power is for transmitting the operation completion signal and the number of retransmissions is the number of transmissions of the operation completion signal to the transceiver.
