    摘要: A communication system is provided that can control which communication sessions with mobile devices are admitted to a wireless access point. The admission decisions are based on actual measurements of radio frequency (RF) utilization. The RF utilization is determined on a per access class basis. Access classes may be defined by protocol but are, generally, voice, video and data. Thus, the system provides the ability to determine admissions that allows for the incorporation of factors including collisions, the distance from the access point to which a mobile device is communicating, and other factors.

    摘要: A wireless communication system is able to balance load in a wireless network based on radio frequency (RF) utilization, signal strength, quality of signal (QoS), and other measures. The load may be dynamically moved to other wireless access points within the wireless network based on the amount of load on one or more of the access points and on the measures. As such, at different load conditions, the system can change the methods of how to determine which access point should handle a communication session. Further, the system provides methods for proactively adjusting the load in the wireless network before any one access point reaches its capacity.

    摘要: Wireless networks and devices are ubiquitous today. For service providers to offer customers QoS and Service Level Agreements (SLAs) means in part providing resilient connectivity of wireless devices with good signal strength, good Signal to Noise and Interference Ratio (SNIR), and adequate useable bandwidth. Doing so requires that devices transmitting and receiving packets use over-the-air bandwidth efficiently and manage over-the-air congestion. According to embodiments of the invention QoS measurements and controls are incorporated only in the network (i.e. APs or controllers) and therefore QoS and SLAs can be achieved with all deployed client stations versus standards based approaches that require additional capabilities in network nodes, client stations and in most cases modifications to the applications. SLAs can be provided exploiting embodiments of the invention for traffic prioritization, capacity improvements through load distribution, and adjacent channel interference mitigation discretely or in combination with standards based mechanisms.

    摘要: A receive circuit for binary signals in time compression multiplexing systems mitigates effects of the local data decay tail and zero line wander by means of a sample-and-hold circuit, having a fast attack and a decay time constant equal to a combination of the transmission line, and dc blocking device time constants followed by a subtracting difference amplifier. Power feed of the line via dc blocking capacitors is thus possible. Also higher receiver gain is possible when sampling switch is left on during local data transmission without receiver instability.
