ABSTRACT:
A method of dynamic spectral bandwidth allocation in home phone-line networking (HPN). An HPN terminal is configured to sense transmission activity in a frequency sub-band corresponding to a broad-band high-speed service, such as ADSL. If no activity is detected, the HPN terminal uses the sub-band for communication with other HPN terminals. As a result, major impediments to HPN networking, such as crosstalk from neighboring home networks and signal attenuation due to the unpredictable topology of the in-home wiring, are minimized or possibly mitigated. In addition, the capacity accessible to HPN terminals may be increased. Consequently, the robustness of HPN networking is improved and higher data throughput rates may be supported.
