Disclosed in the present invention are a data transmission method, an apparatus and an antenna array, in order to realize wide bandwidth data transmission of massive antenna array. The data transmission method comprises: baseband IQ data of multiple CA is grouped via IR data interface module to obtain baseband IQ data of each CA group; for baseband IQ data of each CA group: the baseband IQ data with enhanced data rate of the CA group is up-converted to digital intermediate frequency band by a digital up-conversion module; the digital intermediate frequency signals of the CA group are superposed by a combiner to form a multi-carrier digital intermediate frequency signal; in accordance with the amplitude and phase requirements of each antenna in a group of antenna sharing the multi-carrier digital intermediate frequency signal, the amplitude and phase of the multi-carrier digital intermediate frequency signal are respectively adjusted and transmitted to a digital to analog converter of a corresponding antenna channel; a multi-carrier analog intermediate frequency signal is generated by the digital to analog converter of each antenna channel, and then is transmitted to the corresponding antenna channel.

Disclosed are an access method for a WiFi access point, a WiFi access point and a WiFi system, which relate to communications technology. The present application adds to a WiFi system the RAN and PSCN of a 3G network, and adds a 3G module to an AP, so that the AP can serve as a 3G terminal to access the 3G network, thereby connecting the AP and an AC/BRAS through the RAN and PSCN. Because the 3G network has broader coverage, implementing access point access through the 3G network reduces the complexity of an AP accessing the AC/BRAS.
