Abstract

The embodiment of the invention provides a data transmission method and device based on WIFI, and the method comprises the steps that a first terminal reads data from double buffers after a WIFI channel between the first terminal and a second terminal is built; and the first terminal sends the data to the second terminal through the WIFI channel, the second terminal receives the data transmitted by the first terminal through the WIFI channel, and the second terminal writes the received data into a memory through double threads. The method provided by the embodiment of the invention can improvethe transmission speed of WIFI transmission.

Description

technical field [0001] Embodiments of the present invention relate to communication technologies, and in particular to a WIFI-based data transmission method and device. Background technique [0002] Wireless Fidelity (Wireless Fidelity, WIFI) is a technology that can connect terminals such as personal computers and handheld devices to each other in a wireless manner. At present, WIFI technology can support the transmission of two frequency bands of 2.4G and 5G. [0003] With the rapid development of terminal hardware, it is more and more common to share data between terminals through WIFI. Specifically, when two terminals share data, one terminal A acts as a WIFI hotspot, and the other terminal B selects the terminal A's hotspot to establish a WIFI connection, thereby realizing data sharing between the two. However, in the current way of data transmission based on WIFI, the transmission speed still needs to be improved. Contents of the invention [0004] Embodiments of ...
