Below in conjunction with Figure of description and embodiment the utility model scheme is described.
The utility model embodiment provides a kind of dual-mode device; The structure of this dual-mode device can be like Fig. 3 (a), Fig. 3 (b) and shown in Figure 4; Comprise and be used to provide the wireless relay module 11 that moves standard and cover, portable broadband wireless MIFI module 12, the power module 13 that is used to provide the WLAN covering; The retransmitting antenna 14 that is used for communicating, be used for the donor antenna 15 that communicates with the base station, the passback antenna 17 that is used for the access antenna 16 that communicates with the terminal and is used for communicating with the base station with the terminal, wherein:
Said MIFI module 12 is appreciated that to having the module of existing MIFI functions of the equipments.Further, said MIFI module 12 can comprise WLAN access node WLAN AP submodule 121 and be used to realize the terminal communication submodule 122 of wireless backhaul between WLAN AP submodule and the base station;
Shown in Fig. 3 (a), wireless relay module 11 can a shared power module with MiFi module 12 (comprising WLAN AP submodule 121 and terminal communication submodule 122).
Certainly, wireless relay module 11 also can adopt a power module separately with MiFi module 12.For example, shown in Fig. 3 (b), when power module 13 provided power supply for wireless relay module 11, WLAN AP submodule 121 and terminal communication submodule 122, said power module 13 can comprise the first power supply submodule 131 and second source submodule 132;
The first power supply submodule 131 is connected with wireless relay module 11.
