Description

Device and method for positioning

Technical field

The present invention relates to the field of positioning technologies, and in particular, to an apparatus and method for positioning.

Background technique

With the rapid development of the mobile Internet, the demand for mobile terminals is growing rapidly and the positioning function of mobile terminal devices is also relatively common.

The traditional data card implementation is connected to the computer via a USB (Universal Serial Bus) cable. The device enumerates the USB ports and then virtualizes each port into a different device. Then interact with the computer side driver to achieve the purpose of data transmission.

The same is true for the traditional data card's GPS (Global Positioning System) feature, which enumerates the USB virtual port. GPS data is transmitted via the USB protocol to achieve GPS positioning.

Due to the realization and wide application of the traditional data card GPS function, there is an APP (Application) that reads and writes GPS information through the serial port. The representative product is Google Maps.

UFI (a data card with WIFI capability) is an upgrade of data cards, unlike traditional data card products. In many scenarios, users use it as a router. In this scenario, UFI products do not need to be connected to a computer, but are used as a wireless router. At the same time, in this scenario, since there is no connection with the computer, it is impossible to enumerate the same USB port as the conventional data card for GPS data transmission.
