ABSTRACT:
A novel node device enables transmission of a wideband signal, in compliance with various acceptable transmission standards and protocols. The signal consists of the legacy spectrum of about 5-860 MHz as well as a new downstream spectrum of about 1000-2000 MHz and a new upstream spectrum of about 2000-3000 MHz or about 930-1100 MHz. The novel device enables transfer of additional data in the upstream direction employing multiple upstream bands without making substantial investment in upstream physical node splitting thus providing networking services to residential subscribers, as well as to small and medium-sized businesses (SMB), which may operate under existing DOCSIS protocols and controlled by standard DOCSIS routers (CMTSs).
