Abstract
A remote radio head as part of a small cell or home gateway communication system, comprising a baseband module and a radio unit, the baseband module and the radio unit being configured to be placed on opposing sides of a lossy medium, such as a window. The baseband module is configured to receive and transmit an information signal from a user equipment inside of a structure and the radio unit configured to receive and transmit an information signal from a user equipment or a base station node outside of the structure. The baseband module is further configured to perform signal modulation and demodulation and up-conversion and down-conversion, and the radio unit is configured to perform up-conversion and down-conversion. The baseband module and the radio unit are capable of receiving and transmitting wireless intermediate frequency signals through a lossy medium, so as to avoid signal attenuation, particularly for mmWave wireless signals.
