摘要： Methods, apparatuses, and embodiments related to a technique for controlling channel usage in a wireless network in a multi-band wireless networking system. In a wireless network with multiple wireless networking devices and one or more client devices, communications between the wireless networking devices occurs via a backhaul channel, and communication between the client(s) and the wireless networking devices occurs via a fronthaul channel. Based on interference characteristics of the wireless channels, a device determines a channel usage plan, and communicates the plan via the backhaul channel to the wireless networking devices of the wireless network.

摘要： An access point is configured to communicate with a wireless client device over a plurality of wireless communication channels. The wireless client device has an active operation state and a standby operation state. The access point detects a property of each of a first wireless communication channel and a second wireless communication channel, and applies a policy to the detected properties to select one of the first wireless communication channel and the second wireless communication channel. While the wireless client device is in the active operation state, the access point steers the client device to communicate with the access point over the selected channel.

摘要： Techniques are disclosed for reducing power consumption on a power sensitive wireless device, such as for example a digital wireless camera operating on a battery. According to some techniques, power can be reduced when a portable device is in close proximity to the power sensitive wireless device, such as when a person is home and the recording of video on a digital wireless security camera can be disarmed. Some techniques include filtering mechanisms, which reduce unnecessary information being transmitted to the wireless network circuit of the power sensitive wireless device. Other techniques include modifying or adapting IEEE 802.11 standards to achieve power reducing results such as for example reducing the number of times to wake up to receive the beacons. Also, improved synchronization techniques are implemented such as for example improved synchronization accuracy allows reducing the duration of the wake time for receiving the beacons.

摘要： Systems and methods are introduced for managing a multi-band wireless networking system using a robust control plane. In an embodiment, multiple wireless networking devices are interconnected via a dedicated wireless backhaul to collectively form a single multi-band wireless network providing broad coverage to a client device. The multi-band wireless networking system is managed by wirelessly communicating control information between the multiple wireless networking devices over the control plane in a robust manner that guarantees delivery while minimizing latency. Example techniques for achieving this robust transfer of information include use of robust data rates, use of multiple backhaul channels, use of hybrid Automatic Repeat Request (ARQ), use of dedicated control channels, use of alternative transport protocols, and implementation of distributed router functionality.

摘要： 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.

摘要： In a repeater, a mechanism checks multiple parameters and makes repeater bandwidth, radio configuration, and ADC clock speed adjustments. multiple repeater parameters are checked and the repeater bandwidth is optimized based upon any of adjusting bandwidth based on best throughput; adjusting bandwidth based on Internet speed; adjusting mapping based on overlapping access points (106); adjusting bandwidth based on the client's range; adjusting ADC clock speed; adjusting transmit (TX) radio setting based on associated clients; adjusting receive (RX) radio setting based on associated clients; client type considerations; and adjusting CPU settings based on clients or backhaul. In embodiments, for example, bandwidth can be adjusted from 80 MHz to 40 MHz to 20 MHz or a smaller bandwidth, e.g. 5 MHz, for an 802.11ac/11ax/11ac device. For an 802.11n/a/b/g/ah device, bandwidth can adjusted using from 40 MHz to 20 MHz to a smaller bandwidth, e.g. 1 MHz, 2 MHz, or 5 MHz.

摘要： 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.

摘要： 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.
