Wireless USB (Universal Serial Bus) search network card

Abstract

The invention relates to a wireless USB (Universal Serial Bus) search network card, which comprises a power module, an antenna, a short-wave radio frequency processing module, a radio transceiver module, a WLAN (Wireless Local Area Network) card module, a crystal oscillator and a USB interface module, wherein the antenna, the short-wave radio frequency processing module, a radio transceiver module, the WLAN card module and the USB interface module are connected in sequence; and the power module and the crystal oscillator are connected with the WLAN card module. According to the invention, the problems that a WLAN card cannot search whether a wireless network is available in an area until being connected with a computer, and the operation is fussy are solved by changing the internal structure of the wireless USB search network card; and under the condition that the wireless USB search network card is not connected with equipment, such as the computer and the like, an indication lamp is used for displaying whether a wireless network is available in the area and prompting whether the wireless network is encrypted, therefore operation time of users is effectively shortened.

Description

technical field [0001] The invention designs a wireless network card, in particular relates to a wireless USB search network card, which belongs to the field of wireless communication. Background technique [0002] With the development of wireless communication technology, wireless network equipment has broken the shackles of the installation environment of fixed network equipment. Different types of Internet access equipment are emerging in the domestic market. The speed of wireless network is getting faster and faster, and the stability is getting better and better. The wireless network device of the USB interface module is relatively more convenient to use, and can be used after directly inserting the USB and installing the driver. [0003] However, the wireless network products of the USB interface module currently on the market need to be connected to the computer, and the driver can only be searched for whether there is a wireless network signal available for connectio...

AI Technical Summary

Problems solved by technology

[0003] However, the wireless network products of the USB interface module currently on the market need to be connected to the computer, and the driver can only be searched for whether there is a wireless network signal available for connection at the location. This work cannot be done on the wireless network device alone. ; And when the wireless network device is connected to the computer and the wireless network is searched through the software, it is necessary to connect to know whether the wireless shared data has been encrypted, and the operation is cumbersome
