Wireless memory card and method for realizing full-band communication by adopting wireless memory card

Abstract

The invention relates to the technical field of communication and provides a wireless memory card and a method for realizing full-band communication by adopting the wireless memory card. The wireless memory card is provided with a package structure of a standard memory card; and the package structure is formed by combining a main circuit module with an antenna module which is detachably and electrically connected with the main circuit module. According to the wireless memory card and the method, the wireless memory card is formed by combining the main circuit module with the antenna module, so that the antenna module can be replaced after being detached; the same main circuit module can be combined with the antenna modules with different communication frequency bands and the wireless memory card is more convenient in use and higher in utilization rate. Due to the adoption of the wireless memory card, the full-band communication can be realized by replacing corresponding antenna modules, so that the greater convenience is brought to users and the cost of the users for purchasing the wireless memory cards with various frequency bands is saved.

Description

technical field [0001] The present invention relates to the technical field of communication, and more specifically relates to a wireless memory card and a method for realizing full frequency band communication by using the wireless memory card. Background technique [0002] At present, a wireless memory card disclosed on the market has a packaging structure of an SD card, and a circuit board and an antenna unit are arranged inside the packaging structure, wherein the wireless unit is arranged on a surface of the circuit board. This type of wireless memory card has a small built-in antenna unit, and the frequency band of the antenna unit varies with different sales regions. For this kind of wireless memory card with built-in antenna unit, in a fixed area, once the frequency band of the antenna unit is determined, it cannot be changed. Therefore, this kind of wireless memory card can only realize a single communication in a single area, and cannot be used in cross-band areas....

AI Technical Summary

Problems solved by technology

For this kind of wireless memory card with built-in antenna unit, in a fixed area, once the frequency band of the antenna unit is determined, it cannot be changed. Therefore, this kind of wireless memory card can only realize a single communication in a single area, and cannot be used in cross-band areas. Therefore, , it is inconvenient to use, and the resources are not rationally utilized to the maximum extent, resulting in waste of resources
