Abstract: Layer 2 refers to the Data Link layer of the commonly-referenced multilayered communication model, Open Systems Interconnection (OSI). The Data Link layer is concerned with moving data across the physical links in the network. Embodiments of the invention provide a Layer 2 and management modification to provide and maintain an accurate network map. Embodiments of the invention modify Layer 2 functionality to work with a multi-AP system without central management or with central management, and modify management frames to quickly update the network map when the client roams or when topology changes.

Abstract: A dedicated backhaul for whole home coverage variously applies optimization techniques, e.g. using the 5 GHz high band or low band as a dedicated backhaul; using the 2.4 GHz band as backup if the 5 GHz band fails to reach between nodes; using Ethernet when it is better than the 5 GHz and 2.4 GHz bands and it is available; and using a spanning tree protocol or a variant to avoid loops. The dedicated backhaul is used if the received signal strength indication (RSSI) of the dedicated channel is above a threshold. In embodiments, a daisy chain uses probe request contents to communicate hop count and link quality between the nodes by attempting to route directly if link quality is better than a defined threshold. For each extra hop, there must be some percentage gain over smaller hops. If the link is below some threshold, it is not used.

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: Systems and methods for improving wireless access point communications are provided. Some embodiments contemplate filtering operations such that two or more radios can be used in the 5 GHz or 2.4 GHz band without interfering with each other. Some embodiments employ discrete Low Noise Amplifiers (LNA) and Power Amplifiers (PA) as well as frontend modules. In some examples, filtering may be primarily used on the receiving side to filter out other signals in 5 GHz before they are amplified by an external LNA or LNAs, e.g., as integrated in a WLAN chipset. Filtering may also be performed on the transmit side in some embodiments.

Abstract: Client roaming techniques, such as those set forth in 802.11k, are extended to access point-based client roaming in a distributed multi-band wireless networking system. In particular, access points (APs) implement a series of algorithms that compare signals and make decisions on when to switch a client from one AP to another AP in a distributed multi-band wireless networking system. The invention exploits to advantage the fact that the APs can communicate with each other via the dedicated backhaul.

Abstract: Techniques are disclosed for controlling, in a network device, multiple radio circuits operating in a same or similar frequency band and in close physical proximity. In some embodiments, the radio circuits operate on the same network protocol. The network device can include a coexistence controller coupled to the network circuits. According to some embodiments, the network circuits are each assigned a priority, and the coexistence controller can control operations between the network circuits by selectively adjusting one or more transmission operating parameters of a respective network circuit based on a plurality of operating criteria, which include each network circuit's priority. Among other benefits, the embodiments disclosed herein 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.
