Steven D. Halford - Palm Bay FL, US

Assignee:

Intellectual Ventures I LLC - Wilmington DE

International Classification:

H03C 7/02
H04B 1/02
H04B 7/02

US Classification:

455101, 4552772, 375347

Abstract:

A power-based hardware antenna diversity method for a wireless transceiver with multiple antennas is disclosed. The method is characterized in the steps of setting the transceiver gain at a maximum level to establish a first story of dynamic power range above a noise floor level, using a high-resolution ADC at a large back-off level relative to the noise floor to detect weak signals within the first story of the dynamic power range, switching antennas and measuring power level for each antenna during signal onset, and selecting an antenna having a largest power level.

US Classification:

370318, 370319, 370480

Abstract:

A technique for communicating multimedia data between nodes over coaxial cable, wherein the nodes are connected via a coaxial cable network, is disclosed. In an embodiment, the technique involves establishing a primary channel for communicating between first and second nodes of the coaxial cable network, establishing a secondary channel for communicating between the first and second nodes of the coaxial cable network, wherein the primary and secondary channels are in different frequency bands and wherein the primary channel is used for communicating media access control frames, and communicating a time series of data frames between the first and second nodes using both the primary channel and the secondary channel.

Jack Thomas Matheney - Madison AL, US

Assignee:

Cisco Technology, Inc. - San Jose CA

International Classification:

H04L 1/00

US Classification:

370229, 370252

Abstract:

A method can include calculating an indication of signal quality for a communications channel based on a message from a node over a communications channel of a network. The calculated indication of signal quality can be adjusted based on a prior indication of signal quality to provide an adjusted indication of signal quality. Bitloading for the communications channel can be determined based on the adjusted indication of signal quality.
