Abstract

A wireless relay device emits a beacon and makes a wireless connection with a terminal responding to the beacon, which includes a selecting section capable of alternatively selecting a normal mode in which the beacon is emitted in a first cycle and a power saving mode in which the beacon is emitted in a second cycle longer than the first cycle.

Claims

1. A wireless relay device emitting a beacon and making a wireless connection with a terminal responding to the beacon, the device comprising:

a selecting section capable of alternatively selecting a normal mode in which the beacon is emitted in a first cycle and a power saving mode in which the beacon is emitted in a second cycle longer than the first cycle.

2. The wireless relay device according to claim 1, further comprising:

a user interface section for providing a user interface for making a specification to the selecting section as to select between the normal mode and the power saving mode.

3. A wireless LAN system including the wireless relay device according to claim 1, wherein the system has a control device including a user interface section for providing user interface for making a specification to the selecting section as to select between the normal mode and the power saving on a LAN.

4. The wireless relay device according to claim 2, wherein the user interface section can alternatively specify the normal mode and the power saving mode according to a schedule on a time-series basis.

5. The wireless relay device according to claim 1, wherein the selecting section can alternatively specify the normal mode and the power saving mode according to presence or absence of reception of a beacon from another wireless relay device.

6. The wireless relay device according to claim 1, further comprising:

a cycle changing means capable of changing the second cycle in a stepwise or stepless manner.

7. A method of controlling a wireless relay device emitting a beacon and making a wireless connection with a terminal responding to the beacon,

the method comprising:

alternatively selecting a normal mode in which the beacon is emitted in a first cycle and a power saving mode in which the beacon is emitted in a second cycle longer than the first cycle.

8. (canceled)

9. A non-transitory computer-readable storage medium having stored thereon a program that is executable by a computer of a wireless relay device, the program being executable by the computer to perform functions comprising:

processing for emitting a beacon and making a wireless connection with a terminal responding to the beacon as a selecting section capable of alternatively selecting a noimal mode in which the beacon is emitted in a first cycle and a power saving mode in which the beacon is emitted in a second cycle longer than the first cycle.
