METHOD AND APPARATUS FOR TRANSMITTING DATA

摘要

Embodiments of the present invention disclose a method and an apparatus for transmitting data. The apparatus for transmitting data includes a high frequency radio unit HFRU that is in a communication connection with a site, and a shift frequency radio unit SFRU that is in a communication connection with the HFRU and with a user equipment, where the HFRU includes a high frequency radio unit—indoor device unit HFRU-IDU and a high frequency radio unit—outdoor device unit HFRU-ODU that connects to the HFRU-IDU, and the SFRU includes a high frequency band transceiver and a wireless cellular band transceiver. By converting to-be-transmitted data into intermediate frequency signals for transmission, the method and apparatus for transmitting data according to the embodiments of the present invention can remarkably reduce a data transmission bandwidth, thereby saving bandwidth resources, reducing a data transmission cost, and reducing a device deployment cost.
