Abstract: Techniques are disclosed for reducing interference, in a network device, among multiple radio circuits operating in a same or similar frequency band and in close physical proximity. In some embodiments, a network device includes a first and a second wireless network circuit. The network circuits operate in a same radio frequency band and are collocated. The second network circuit is assigned a higher priority than the first network circuit. The device further includes a coexistence controller coupled to the network circuits via a communication bus and configured to selectively suppress transmitting operations of the first network circuit during receiving operations of the second network circuit. Among other benefits, the embodiments can increase wireless network bandwidth and reduce mobile device power consumption by providing coordination among the radio circuits so that the transmitting and receiving operations are performed in a way that they do not interfere with their respective antennas.

Abstract: In various aspects, code-based indicia contain secured network access credentials. In some aspects, a computer processor receives user input that specifies secured network access credentials, and the computer processor creates or modifies credentials for establishing a secured network connection. In these aspects, the computer processor generates code-based indicia that contain at least part of the secured network access credentials. In other aspects, a computer processor scans the code-based indicia and extracts the network access credentials. In these aspects, the computer processor employs the network access credentials to establish the secured network connection. In additional aspects, a network router apparatus renders the code-based indicia to an active display. In further aspects, a network router apparatus conditions grant of network access to a device on receipt from the device of an answer to a security question included in the secured network access credentials.

Abstract: Various of the disclosed embodiments provide systems and methods for enabling LTE® and wireless, e.g., ISM band, applications to coexist on a same device or on separate devices in proximity to one another. Some embodiments implement a remediation and/or channel transition process for the wireless devices following detection of LTE®-related interference. During remediation, the device may, e.g., adjust the wireless power levels, EDCA backoff times, signal thresholds, etc. In some embodiments, if the remediation actions prove ineffective, the wireless peers may be relocated to a channel further from the interfering LTE® band. The determination to remediate or reallocate may be based on various contextual factors, e.g., the character of the peer devices and the applications being run.

Abstract: A network device is configured to implement a QoS function to optimize bandwidth utilization includes a memory configured to store a high priority throughput value and a low priority bandwidth value, a network device input to communicate a data stream including a plurality of data packets to and from at least one computer system on the internal network, and a network device output to communicate the data stream including the plurality of data packets to and from at least one computer system on the external network. The network device further includes a computer processor configured to execute steps stored in non-volatile memory, the steps including identifying high priority data packets in the data stream to detect the high priority throughput value, setting the low priority bandwidth value, and periodically adjusting the low priority bandwidth value. This QoS function can work without the knowledge of actual bandwidth for any link in the networks.

Abstract: A receiver is provided that receives signals from a device under test (DUT) for one or more modes of operation. For each mode, the system detects beacon transmission signals from the DUT, and counts the number of beacons for a period of time. If the count is not consistent with an expected count, e.g. a stored value, the system may preferably provide an output to indicate that there is a problem with the DUT. If the count is consistent with the expected count, the system may preferably perform further testing for other modes of operation. If the count output of the DUT is consistent with expected counts over each of the operation modes, the system may provide an indication that the DUT has passed the beacon tests.

Abstract: Various embodiments disclose systems and methods for employing a Sub1G signal (e.g. a signal in the range of approximately 500 Mhz or 800 mHz) for use with internal and/or external components of various user devices. The Sub1G region may provide a path loss advantage over traditional 2.4 and 5 Ghz systems because of the lower frequency in free-space path loss model. Sub 1G may also present less interference compared to 2.4 GHz (e.g., better QoS for applications such as VOIP, Gaming, etc.). In some of the disclosed embodiments, Sub1G may be employed using current 2.4G or 5G Wireless LAN chipset with RF Up/Down Converters. In some embodiments, the Sub1G approach may be used to create a Long Range Bridge, Long Range Extender, Long Range Client, Long Range Hotspot, etc.

Abstract translation: 各种实施例公开了用于使用与各种用户装置的内部和/或外部组件一起使用的Sub1G信号（例如，大约500Mhz或800mHz的信号）的系统和方法。 由于自由空间路径损耗模型的频率较低，Sub1G区域可能比传统的2.4和5 GHz系统提供路径损耗优势。 与1GHz相比，Sub 1G还可以呈现更少的干扰（例如，对于诸如VOIP，游戏等应用的更好的QoS）。 在一些所公开的实施例中，可以使用具有RF上/下转换器的当前2.4G或5G无线LAN芯片组来采用Sub1G。 在一些实施例中，Sub1G方法可用于创建长距离桥，长距离扩展器，远程客户端，远程热点等。

Abstract: A dual band spectrum allocation system and method for wireless data communications uses discrete bands for upstream and downstream data communications. A preferred embodiment uses unlicensed UNII bands for license-free data transmissions from a subscriber to a hub, and uses relatively interference free licensed bands for data transmissions from a hub to subscribers, thereby allowing use of greater bandwidth, simplifying system licensing and reducing filtering requirements for subscribers.
