Abstract
In one embodiment, a system for telecommunications includes a base band unit, a backhaul network, a shared network, a cascaded chain of remote radio heads, and an optical node coupled to the cascaded chain of remote radio heads. The backhaul network is coupled to the base band unit and to the shared network. The cascaded chain includes a first remote radio head coupled to a first set of antennas, a second remote radio head coupled to a second set of antennas. The second remote radio head is coupled to the first remote radio head through the shared network. The cascaded chain of remote radio heads is coupled to the shared network. The second remote radio head is configured to receive signals from the second set of antennas and communicate the signals to the first remote radio head. The first remote radio head is configured to receive signals from the first set of antennas, receive signals from the from the second remote radio head, and transmit the signals to the base band unit. The base band unit, the first remote radio head, and the second remote radio head communicate through a digital radio interface. The optical node is configured to communicate signals between the backhaul network and data subscribers accessing the shared network.
