Abstract
A wireless communication method and system utilizing optical transmission technology to transport analog signals directly to/from the antenna, without ADC/DAC, so that the optical transport facility can be utilized more efficiently and there is no need to adapt the digital data rate to the transport capacity, as the analog transmission is independent of the digits buried in the given spectrum. Complicated operation is moved into a centralized location, so that a cell site (base station) is light and flexible. In contrast, the standardized approach in the industry, which involves digitized interface between the antenna and the control processor, hits capacity limits of the current transport technology.
