| Zusammenfassung: | An expansion device includes a casing and a wireless transceiving module. The casing includes a receiving slot suitable for accommodating a mobile communication device, wherein the mobile communication device includes at least an antenna to operate at least one communication band. When the mobile communication device is accommodated in the receiving slot, the wireless transceiving module receives electromagnetic wave at the communication band, generates at least one radio frequency signal, and wirelessly couples the radio frequency signal to the antenna in the mobile communication device. |
