Abstract
Wireless interface nodes couple to a wireless protocol controller over an HFC network. The wireless controller, located at the head end, interfaces the CMTS with the HFC. Thus, a conversion between standard packets and wireless protocol packets occurs; packets are transmitted/received at standard HFC frequencies to/from the wireless interface nodes. The wireless nodes upconvert downstream signals to a wireless frequency and transmit same from an antenna. Upstream signals received from wireless user devices at wireless frequencies are downconverted at the wireless node to HFC upstream frequencies. When downstream packet signals from the head end are detected, upstream signal processing at the node is disabled. If this results in loss of preamble bits, additional preamble bits may be added at the head end. Upstream processing may be disabled unless upstream packets are present. DOCSIS in-band signaling may be used to communicate control information between the head end and the wireless nodes.
