A method includes determining a delivery performance of a data flow being transmitted from a first network equipment to a second network equipment over a network; determining whether the network is congested based on the determined delivery performance of the data flow being transmitted to the second network equipment; and pacing delivery of the data flow to the second network equipment by reducing a rate at which the data flow is delivered to the second network equipment when the network is determined to be congested.

A method to regulate a signal-to-noise ratio (SNR) in a rate adaptation includes: transmitting a frame; determining a status of the transmitted frame; computing a probability of a channel of the transmitted frame being in an idle mode; computing an SNR offset based on the status of the transmitted frame and the probability; and regulating an SNR for transmission, based on the SNR offset.

A wireless audio system using low overhead in-band control and audio transmission is provided. The wireless audio system includes a first wireless audio device configured to operate separate physical layer channels for audio data and control data, and transmit the audio data and control data using a single wideband carrier. The wireless audio system also includes one or more second wireless audio devices configured to receive the audio data and control data, and execute an instruction based on the control data.

A serial communication link includes a receiver and a transmitter coupled to the receiver by a first serial communication lane operating at a first speed, and a second serial communication lane operating at a second speed. The second speed is slower than the first speed. The transmitter can include bit steering logic that receives a data stream, provides a first number of bits of the data stream to the first serial communication lane, and provides a second number of bits to the second serial communication lane. The proportion of the first number of bits to the second number of bits is the same as a proportion of the first speed to the second speed.

Various embodiments for regulating link speed for performance enhancement and port diagnosis are provided. In response to identifying an amount of errors in a communications link above a predetermined threshold, an applicable transmission speed is selectively reduced. If errors identified at the reduced transmission speed are found to decrease, a communications port incorporating the communications link is flagged as potentially dirty, and if the errors identified at the reduced transmission speed are found to remain constant, the communications port is flagged as potentially bad.

The performance and ease of management of wireless communications environments is improved by a mechanism that enables access points (APs) to perform automatic channel selection. A wireless network can therefore include multiple APs, each of which will automatically choose a channel such that channel usage is optimized. Furthermore, APs can perform automatic power adjustment so that multiple APs can operate on the same channel while minimizing interference with each other. Wireless stations are load balanced across APs so that user bandwidth is optimized. A movement detection scheme provides seamless roaming of stations between APs.

A bandwidth allocation and monitoring method may divide available bandwidth on a shared communication medium into a plurality of discrete tones that can be individually allocated to modems on an as-needed basis. The effective modulation rate that a particular modem can use for each discrete tone can be monitored over time using a schedule of pilot tones transmitted from the modems on different tones at different times. The schedule may define representative pilot tones, in which case effective modulation rates for neighboring tones may be inferred from a determined effective modulation rate of a pilot tone.

In other aspects, another apparatus and a method are also disclosed.
