Powerline communication networks can be subject to burst interference resulting in loss of throughput and data corruption. A transmitting network device and a receiving network device of a powerline communication network can be configured to select a best performing powerline terminal coupling configuration for powerline communications. The transmitting network device can determine performance measurements associated with each of a plurality of powerline communication channels. The transmitting network device can select a best performing powerline communication channel based on the performance measurements, and can provide an indication of the best performing powerline communication channel to the receiving network device. The transmitting and the receiving network devices can each configure their respective terminal connections to switch to the best performing powerline communication channel. Subsequent communications between the transmitting and the receiving network devices can be initiated via the best performing powerline communication channel.

An access contention scheme having both multi-level priorities and a contention-free access indicator for use by a station in a network of stations. When a contention control indicator is detected for a contention period, a station having a frame to transmit determines from the contention control indicator if it is permitted to contend for access to the transmission medium during the contention period. The station determines if the contention control indicator indicates a contention-free access and, if the contention control information indicates a contention-free access, the station determines if a channel access priority level associated with the frame to be transmitted is higher than a channel access priority level associated with a last transmitted frame. If the channel access priority level associated with the frame to be transmitted is higher, the station detects whether any station in the network of stations intends to contend for access to the medium at a channel access priority level that is higher than the channel access priority level associated with the frame to be transmitted. If so, the station defers contention for access.

Media Access Control (MAC) layer transmit and receive buffering with multi-level prioritization. The receive buffering allocates receive buffers for receiving frame data from a PHY interface in priority order using both a static and dynamic buffer allocation, and delivers completed buffers queued in a multi-level priority queue to a host interface highest priority first. The transmit buffering delivers completed buffers queued in a multi-level priority queue to the PHY interface in priority order. When the multi-level priority queue contains a buffer that is higher priority than one being prepared for transmit, a priority-based interruption causes the transmit processing of the buffer to be suspended at its current state with the higher priority buffer taking its place. Upon completion of the higher priority buffer, the suspended buffer is resumed at its current state.

An apparatus and methods are provided for network radio frequency ("RF") data communications. The apparatus preferably has an extended channel radio transmitter for selectively transmitting data communication radio signals across a plurality of different carrier frequencies which respectively define a plurality of extended data communication channels. The transmitter preferably includes a channel scanner for scanning the extended data communication channels for availability prior to transmitting across a selected one of the plurality of extended data communication channels. An extended channel radio receiver is responsive to the extended channel radio transmitter for receiving the data communication signals from the selected one of the extended data communication channels. The extended channel radio receiver preferably includes an extended channel data detection synchronizer responsive to the data communications signals being received by the receiver for synchronizing the transmitting and receiving of the data communication signals across the extended data communications channels. Any and all extended channel contending transmitters and receivers or transceivers within a network preferably sense and synchronize to the extended channel being transmitted within a predetermined period of time, i. e.

Within a domain of a master device, devices that share a power line as a communications medium monitor signal detection windows to sense network status. The devices transmit sensed network status to the master device. The master device allocates channel resources based on the network statuses communicated by the devices within the domain.

An access contention scheme is described for use by a station in a network of stations. Access contention by a station having a frame to be transmitted includes detecting contention control information for a contention period and determining from the contention control information if the station is permitted to contend for access to a transmission medium to which the stations are connected during the contention period. When a contention control indicator is detected for a contention period, a station having a frame to transmit determines from the contention control indicator if it is permitted to contend for access to the transmission medium during the contention period.
