    Abstract: An apparatus and method transfers signals between a fiber network and a wireless network antenna. In a fiber to wireless stage, fiber signals are optically transferred from the fiber network and converted into RF signals compatible with the DOCSIS interface standard. The RF signals are electronically converted into data packets, the data packets are electronically converted into baseband digital signals, and the digital signals are converted into analog signals, before being transferred to the network antenna for wireless transmission. The data packets, digital signals, and analog signals are compatible with the IEEE 802.l6 wireless networking standard. Conversely, in a wireless to fiber stage, the analog signals are transferred from the antenna, and converted into digital signals, which are then electronically converted into data packets. The data packets are electronically converted into RF signals, which are next converted into fiber signals, before being optically transferred to the fiber network.
