Embodiment Construction

[0036] The basic idea of ​​the present invention is: during data transmission, the data information including the identity authentication information is sent to the corresponding terminal user according to the WiFi network confirmed by the identity authentication information.

[0037] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0038] The implementation method of the specific embodiment of data transmission in the WiFi network of the present invention is as follows: figure 2 shown, including the following steps:

[0039]Step 201: After confirming that the terminal user is within the range of the public local area network of multiple WiFi networks, send identity authentication information to each WiFi network, and confirm the WiFi network used;

[0040] Here, the identity authentication information includes: the authentication function flag, the content of the authentication function...

Abstract

The invention discloses a data transmission method in a WiFi network, which comprises the following step: when data transmission is carried out, sending data information comprising identity authentication information to a corresponding terminal user according to a WiFi network confirmed by the identity authentication information. Meantime, the invention also discloses a data transmission system in the WiFi network. The method and system of the invention can effectively avoid collision in the WiFi network, and can solve the problem of avoiding data collision depending on increasing interframe space in the working process of a CSMA/CA protocol, thereby improving the interactive efficiency between a network side and a user terminal.

Description

technical field [0001] The present invention relates to a wireless fidelity (WiFi, Wireless Fidelity) network technology, in particular to a method and system for data transmission in a WiFi network. Background technique [0002] WiFi network is one of the mainstream standards of wireless local area network at present. It is the same as the Bluetooth network, which belongs to the short-range wireless transmission technology that can be used in offices and homes. Compared with Bluetooth technology, WiFi has the following advantages: [0003] First of all, the coverage of WiFi network is wide. The radio wave coverage based on Bluetooth technology is very small, with a radius of only about 50 feet, or about 15 meters, while the radius of WiFi technology can reach about 300 feet, or about 100 meters. Therefore, the WiFi network is within the scope of the entire building. can be used. Moreover, a new type of switch recently launched can extend the communication distance of th...
