The present invention relates to the related technical field of wireless communication modules, in particular to a wireless backup communication expansion module.

At present, globalized enterprises will establish private network communication and data systems to meet their application requirements such as data synchronization, Internet calling (VoIP), and Internet video conferencing. Figure 1 shows the architecture of an existing network communication and system. As shown in Figure 1, the necessary devices for constructing network communications and systems include: server 1’, data center 2’, and network management computer 3’. After establishing a private network communication and data system, if the employees of the foreign branch have access to the company's internal data, they can connect to the data center 2'of the head office to access the data.

Traditionally, enterprises will lease MultiProtocol Label Switching (MPLS) lines from Internet service providers (ISP), as shown in Figure 1, the first channel L1' to ensure the network Transmission quality of VoIP and Internet video conferences. Furthermore, with the continuous improvement of network transmission speeds, some enterprises have gradually turned to the relatively inexpensive ADSL or Cable Modem, using the Internet as the data transmission channel for their network communication and data systems, such as the first 1 shows the second channel L2'.

Furthermore, as shown in Figure 2, the interface unit 53' includes an interface card slot 531' compliant with the B key specification and a PCIe interface card 532'.

Please refer to Figure 1 and Figure 2 repeatedly. It is worth noting that although the wireless communication expansion module 5'is mainly used to enable the server 1'and the base station 4'to pass through the mobile communication network channel (that is, the third channel L3') as an enterprise One of the data transmission channels of private network communication and data systems, but practical experience shows that when the wireless communication processing unit 52' and/or the mobile communication unit 51' fails to operate normally or fails, the company's private network communication And the data system cannot use the third channel L3' to meet application requirements such as data synchronization, Internet calling (VoIP), and Internet video conferencing.
