Abstract
Four independent technologies are incorporated in this invention to efficiently and cost effectively implement dynamic last mile connectivity. The four technologies are passive optical networks (PON), Small cell, wavefront multiplexing (or K-muxing), and digital beam forming (DBF). We have filed US patents for communications architectures featuring K-muxing overlaid over low cost of PON. Those inventions relate particularly to resource allocation in passive optical networks (PON) via wavefront multiplexing (WF-muxing or K-muxing) and wavefront demultiplexing (WF-demuxing or K-demuxing). The “WF-muxing in PON” can be configured for performing remote digital beam forming (RDBF) over a service area covered by multiple small cells. The RDBF may generate multiple shaped beams with enhanced connectivity and better isolations over a same frequency slot concurrently to serve multiple users over the coverage area.
