| 摘要 |
The present disclosure discloses an LTE communication card, which comprises: an SDIO interface, comprising data pins adapted to be selectively inserted into an SDIO card slot of an electronic device; an LTE baseband processing unit connected to the data pins, being configured to obtain from the data pins a first data signal supplied by the electronic device and modulate the first data signal; an LTE transceiving unit, being configured to obtain the first data signal that has been modulated; and an antenna unit, being configured to transmit the first data signal, and further obtain an LTE radio frequency (RF) signal from the outside and transmit the LTE RF signal to the LTE transceiving unit, and the LTE RF signal being transmitted by the LTE transceiving unit to the LTE baseband processing unit and then demodulated by the LTE baseband processing unit to obtain a second data signal for transmission to the electronic device via the data pins. The present disclosure further discloses an LTE communication system. Through the above disclosure, the present disclosure can impart an LTE wireless communication function to an electronic device that supports the SDIO protocol so as to enrich functions of the electronic device, improve users' experiences and reduce the production cost.
