Provisioning ubiquitous broadband wireless services necessitates the duplication of the radio equipment or/and the reduction of the size of the radio cells. However, both approaches are not economically viable for the operators. The concept of distributed antennas is proposed as an alternative solution offering low-cost broadband access. In this matter, the authors propose an innovative Radio Access Network (RAN) architecture called GeRoFAN for Generic Radio-over-Fiber Access Network. The GeRoFAN architecture is based on a transparent optical loop connecting low-cost 4G radio-system antennas using analog Radio-over-Fiber (RoF) technology.
