Abstract

A communication apparatus, that can concurrently execute a first mode of joining a wireless network formed by another apparatus and a second mode of forming a wireless network, can determine whether a first wireless channel used in the first mode executed by the communication apparatus is a specific channel requiring a device to have a predetermined function to avoid radio-wave interference when the device operates as an apparatus that forms a wireless network using the wireless channel and controls, when executing the first mode and the second mode concurrently, an operation of the second mode in accordance with a result of the determination.

First claim

What is claimed is:

1. A communication apparatus that providing a first mode of joining a wireless network formed by another apparatus and a second mode of forming a wireless network, the first and second modes being executable concurrently, the communication apparatus comprising:
at least one memory storing instructions; and
at least one processor configured to implement the instructions and execute a plurality of tasks, including, while the communication apparatus is concurrently executing the first and second modes:
a determination task that determines whether a first wireless channel used in the first mode is a specific wireless channel requiring the communication apparatus to include a predetermined function to avoid radio-wave interference when operating the communication apparatus in the second mode using the first wireless channel; and
a control task that:
in a case where the determination task determines that the first wireless channel is the specific wireless channel, controls the communication apparatus to not operate the second mode using the first wireless channel; and
in a case where the determination task determines that the first wireless channel is not the specific wireless channel, controls the communication apparatus to operate the second mode using the first wireless channel.

2. The apparatus according to claim 1 , wherein the specific wireless channel is a wireless channel in a 5-GHz band.

3. The apparatus according to claim 1 , wherein the specific wireless channel is a wireless channel that requires the communication apparatus to include the predetermined function as a condition of use in the second mode.

4. The apparatus according to claim 3 , wherein the predetermined function is a function of detecting radar waves.

5. The apparatus according to claim 1 , wherein the first mode is a Station mode complying with the IEEE802.11 standard and the second mode is an Access Point mode complying with the IEEE802.11 standard.

6. The apparatus according to claim 1 , further comprising one wireless chip that performs wireless communication in the first mode and wireless communication in the second mode.

7. A control method for a communication apparatus that a first mode of joining a wireless network formed by another apparatus and a second mode of forming a wireless network, the first and second modes being executable concurrently, the method comprising the steps of, while the communication apparatus is concurrently executing the first and second modes:
determining whether a first wireless channel used in the first mode is a specific wireless channel requiring the communication apparatus to include a predetermined function to avoid radio-wave interference when operating the communication apparatus in the second mode using the first wireless channel;
controlling, in a case where the determining step determines that the first wireless channel is the specific wireless channel, the communication apparatus to not operate the second mode using the first wireless channel; and
controlling, in a case where the determining step determines that the first wireless channel is not the specific wireless channel, the communication apparatus to operate the second mode using the first wireless channel.

8. A non-transitory computer readable storage medium for storing a program executable by a computer included in a communication apparatus that provide a first mode of joining a wireless network formed by another apparatus and a second mode of forming a wireless network, the first and second mode being executable concurrently, to execute a method comprising the steps of, while the communication apparatus is concurrently executing the first and second modes:
determining whether a first wireless channel used in the first mode is a specific wireless channel requiring the communication apparatus to include a predetermined function to avoid radio-wave interference when operating the communication apparatus in the second mode using the first wireless channel;
controlling, in a case where the determining step determines that the first wireless channel is the specific wireless channel, the communication apparatus to not operate the second mode using the first wireless channel; and
controlling, in a case where the determining step determines that the first wireless channel is not the specific wireless channel, the communication apparatus to operate second mode using the first wireless channel.
