The TS includes a user interface (“UI”), a test bed engine, and a TS manager. The UI facilitates interactive communication between TS and user via an interactive graphical representations showing, for example, test configurations and test results. The test bed engine uses a set of test beds to conduct tests on attached devices or routers which are also known as device under tests (“DUTs”) or unit under tests (“UUTs”). The TS manager is configured to provide a test environment with one or more emulated communication networks for verifying functionalities of every DUT.

Abstract: Various of the disclosed embodiments improve the operations of a combined access point/Cable modem. Though the access point component and the Cable modem component may perform operations in different spectrums, harmonics in the Cable spectrum may interfere with operations, e.g., in the 2.4 GHz and 5 GHz range, of the access point. Some embodiments implement a remediation and/or channel transition process for the access point following detection of Cable-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 Cable harmonics. 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: Wireless communication under IEEE 802.11 standards utilizing carrier specific interference mitigation where an AP or UE employs an ultra-wideband tuner to evaluate available spectrum between several communication bands. Rather than being constrained to communicate in a single communication band, the AP and UEs may utilize more than one communication band to communicate with one another. In doing so, the AP and UE search across several bands and measure interference on a carrier-by-carrier basis across those bands. Either of the AP and UE may select a cluster of carriers for communication, where the cluster of carriers may comprise 1) contiguous carriers in a single sub-channel, 2) contiguous carriers spanning across more than one sub-channel, 3) discontinuous carriers in a single sub-channel, or 4) discontinuous carriers spanning across more than one sub-channel. The mapping between a cluster and its carriers can be fixed or reconfigurable.

Abstract: Techniques are disclosed for a wireless router or residential gateway to distinguish power-sensitive wireless sensors and provide separate treatments thereto for low power consumption connections. In some embodiments, a network device includes a wireless network circuit, and control circuitry coupled to the network circuit and configured to, upon receipt of a request of connection from a client, identify whether the client is power-sensitive. The network device can further cause, if the client is identified as power-sensitive, the power-sensitive client to connect using a low-power connection while maintaining a regular connection to other regular clients. The low-power connection can be operated on a first channel different from but in a same frequency band as a second channel on which the regular connection is operated.

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: A heat sink assembly uses a pin and a spring arrangement to bias a heat sink against an underlying support with an electrical component in between. A lock cap, mounted on a head of the pin, selectively engages a retainer formed beneath an upper end of a heat dissipating element or fin of the heat sink to precompress the spring. When the lock cap is engaged and the spring is precompressed, the pin may be attached to the underlying support without opposing the force of the spring. When the attachment is complete and the lock cap is disengaged, the spring is allowed to act against the head of the pin and the base of the heat sink to operatively bias the heat sink against the underlying support.
