Embodiment Construction
[0022] like figure 1 As shown, the method for combining WiFi access point devices provided by the embodiment of the present invention includes:
[0023] Step 11, when the first WiFi access point device detects that the communication interface is connected to the second WiFi access point device, acquire the channel information of the second WiFi access point device;
[0024] Step 12, the first WiFi access point device sets its current channel to be consistent with the channel of the second WiFi access point device;
[0025] Step 13, the first WiFi access point device is used in combination with the second WiFi access point device on the channel of the second WiFi access point device.
[0026] Normally, when two WiFi access points are used together, we will try to avoid the same channel to prevent interference on the same channel, but after testing and verification, we found that there is a distance limit within the distance limit , the interference between two WiFi access poi...

The embodiment of the invention discloses a method, a device and a system for combined use of wireless fidelity (WiFi) access point equipment. The method comprises the following steps that: when first WiFi access point equipment detects that a communication interface communicates with second WiFi access point equipment, the first WiFi access point equipment acquires channel information of the second WiFi access point equipment and sets a current channel of the first WiFi access point equipment to be consistent with a channel of the second WiFi access point equipment; and the first WiFi access point equipment is combined with the second WiFi access point equipment for use. The distance between the first WiFi access point equipment and the second WiFi access point equipment can be regarded to be smaller than a certain set distance limit value when the first WiFi access point equipment and the second WiFi access point equipment communicate with each other, so that within the distance limit value, interference between the first WiFi access point equipment and the second WiFi access point equipment on the same channel is obviously smaller than interference between the first WiFi access point equipment and the second WiFi access point equipment on different channels; therefore, through the same-frequency operation of the embodiment of the invention, mutual interference during near-distance combined use can be reduced.
Description
technical field [0001] The present invention relates to wireless broadband WiFi (wireless fidelity) technology, in particular to a method, device and system for combined use of WiFi access points (Access Point). Background technique [0002] At present, WiFi (IEEE 802.11) technology is widely used. WiFi access point refers to AP (Access Point) used for wireless connection. It can be divided into two types in terms of mobile performance: fixed WiFi access point and mobile WiFi access point. point. There are more and more scenarios where WiFi access points are used in combination, especially after the application of mobile WiFi access points (Pocket WiFi) rises. Users may have an indoor fixed WiFi access point, which is mainly used at home; there is also a mobile WiFi access point, which is mainly used outdoors; in some cases, indoor fixed WiFi access points and mobile WiFi access points are also used They can be used in combination. For example, a fixed WiFi access point ca...
