摘要： Protocols and algorithms for contention-based adaptive modulation networks, typically used in unlicensed bands. A wireless system in which high modulation rate packets are prioritized over low rate packets. The wireless system is configured to process communication signals from plural user portable devices having wireless access points capable of dynamically adjusting access point transmit power on a user-by-user basis to a minimum level required to achieve a target signal-to-noise ratio from each user portable device irrespective of the interference observed on the link is also disclosed. The wireless system is also capable of dynamically adjusting access point transmitter power and receiver sensitivity on a user-by-user basis to a minimum level required to achieve the highest possible modulation rate.

摘要： Described herein are a number of steps, methods and/or solutions that can be applied to greatly improve attenuation control of RF signals in cable plant. The present disclosure is directed to a cable modem auto-attenuation system or any other signal transferring system. The system may be capable of taking a high-power signal from the cable plant's service line, dropping the power value down to a usable level and transmitting the signal to a cable modem while eliminating the need for rigorous manual adjustments that a normal cable modem often requires. In certain embodiments, the system may be integrated into a separate device connected between the modem and the cable company service line and configured to handle upstream and downstream attenuation separately or jointly.

摘要： A system and method is provided for estimating the T1 timing error and clock recovery errors by processing timing information from the associated pseudowire packet stream(s) from which the T1 is derived. The timing errors are presented as MTIE measurements which are used to present alarms for a Network Operation Control centre and are used to accurately alarm error conditions where the regenerated or derived T1 signal does not meet MTIE or clock accuracy errors. This alarm is intended to detect conditions of excessive packet jitter, wander or phase transients which may exist in the data network over which the pseudowire stream is transported. In another aspect, the errors are used to control the regeneration of the T1 clock information.
摘要翻译：提供了一种系统和方法，用于通过处理从其导出T1的相关伪线分组流中的定时信息来估计T1定时误差和时钟恢复错误。定时误差表示为MTIE测量，用于向网络操作控制中心发出报警，并用于准确报警重新生成或导出的T1信号不符合MTIE或时钟精度误差的错误状态。该警报旨在检测可能存在于传输伪线流的数据网络中的过多数据包抖动，漂移或相位瞬变的情况。另一方面，错误用于控制T1时钟信息的再生。
