METHOD AND DEVICE FOR IMPROVING WIRELESS PERFORMANCE OF THE WIRELESS DATA TERMINAL DEVICE

摘要

A wireless data terminal device is provided. The wireless data terminal device includes a separated USB interface and a main circuit board; there are at least two redundancy grounding connections between the separated USB interface and the main circuit board, and the grounding points of the at least two redundancy grounding connections are not adjacent each other. A method for improving wireless performance of the wireless data terminal device is provided simultaneously. By using the wireless data terminal device or the method for improving wireless performance of the wireless data terminal device, the connection between the ground level of the wireless data terminal device and the ground level of the computer is increased effectively, and the wireless indicator of the wireless data terminal device is improved.
