Terminal device of wireless network

Abstract

The terminal equipment of the wireless network comprises a shell, wherein the shell is provided with a microcomputer with control logic, a memory for storing a plurality of area data, a radio frequency unit and a position acquisition unit; when the microcomputer executes the control logic, the following actions are carried out, namely: the current position of the shell is obtained through the position obtaining unit; the current position is compared with a coverage area of a global coordinate system in a plurality of pieces of area data in the memory; and if the current position is located inthe coverage area of the global coordinate system in one piece of area data, the microcomputer selects the piece of area data as a wireless network specification, and controls the radio frequency unitto communicate with external wireless network equipment according to the frequency, bandwidth, power and communication flow in the piece of area data.

Description

technical field [0001] The present invention relates to a wireless network technology, in particular to a terminal device of a wireless network that can adapt itself to the wireless transmission specification of the area in different areas. Background technique [0002] The current wireless network has different wireless network specifications (including frequency, bandwidth, or power, etc.) in various regions or countries around the world. For example, the wireless network specifications of the European Union are different from those of the United States. Moreover, in European countries Therefore, before a wireless terminal device leaves the factory, the wireless terminal device must be set according to the wireless network specification of the place where it is to be shipped, so that it can work normally at the place where it is shipped. [0003] However, if the wireless terminal equipment is movable, for example, the wireless terminal equipment used by the detection equip...

Problems solved by technology

[0003] However, if the wireless terminal equipment can be moved, for example, the wireless terminal equipment installed on the vehicle needs to be used by the detection equipment, it may leave its original location with the movement of the vehicle. In this way, This wireless terminal device may enter an area with different wireless network specifications, and then the problem of not working properly will occur. This problem needs to be overcome
