Wireless device, system and method for selecting online target according to signal quality

Abstract

The invention discloses a wireless device, a system, and a method for selecting an online target according to signal quality. The quality of a signal selected through a wireless device is the best, other wireless devices of which signal quality is not less than the threshold value and the lasting time reaches the preset time can be used as candidate devices; when the wireless device is also selected by the selected candidate devices, the only online technical mean is built between two wireless devices; under the dynamic and complex environment, a work station and an access point are automatically negotiated to build a stable linear topology, and the topology is updated in real time to meet the environment change.

Description

technical field [0001] A wireless device, system and method for establishing a connection, especially a wireless device, system and method for selecting a connection target according to signal quality. Background technique [0002] In some applications, a linear network topology must be used, such as narrow and long spaces, but because of the characteristics of wireless networks that cannot specify the corresponding connection, when using a wireless network to establish a linear network, due to the connection of an access point There may be multiple other access points that can be connected within the range. In this way, it will be difficult to achieve the expected linear topology after each access point is connected to each other. [0003] In the current network environment using linear network topology, if the wireless network connection environment is simple, the nodes are fixed, and the topology rarely changes, such as a backbone network, the connection parameters of eac...

[0002] In some applications, a linear network topology must be used, such as narrow and long spaces, but because of the characteristics of wireless networks that cannot specify the corresponding connection, when using a wireless network to establish a linear network, due to the connection of an access point There may be multiple other access points that can be connected within the range. In this way, it will be difficult to achieve the expected linear topology after each access point is connected to each other.

[0003] In the current network environment using linear network topology, if the wireless network connection environment is simple, the nodes are fixed, and the topology rarely changes, such as a backbone network, the connection parameters of each access point are usually manually modified. , so a...
