Wireless extension of a wired network through the use of strand-mounted access nodes. In some aspects, private network addresses may be assigned to wireless devices, and corresponding data traffic may be routed to a centralized management/provisioning platform for further network access.

Wireless extension of broadband access

A bandwidth allocation and monitoring method may divide available bandwidth on a shared communication medium into a plurality of discrete tones that can be individually allocated to modems on an as-needed basis. The effective modulation rate that a particular modem can use for each discrete tone can be monitored over time using a schedule of pilot tones transmitted from the modems on different tones at different times. The schedule may define representative pilot tones, in which case effective modulation rates for neighboring tones may be inferred from a determined effective modulation rate of a pilot tone.

Managing upstream transmission in a network

Methods and systems are disclosed for using a common frequency spectrum for simultaneous upstream and downstream communications in a network by implementing directional diversity techniques. Non-reciprocal coupling devices, such as circulators, may be configured in the network to provide unidirectional transmission of each signal to prevent interference. In some embodiments, feed-forward interference cancellation is utilized to increase signal isolation of upstream and downstream signals.

Transmitting signals using directional diversity over a network

Methods and systems for managing power consumption of network devices are disclosed. An example method can comprise detecting a triggering condition and reducing functionality of a network device based on detecting the triggering condition. The method can comprise detecting, at the network device, a user device, restoring functionality of the network device in response to detecting the user device, and transmitting information to the user device after restoring functionality of the network device.

Methods and systems for managing power consumption of the network devices

Methods and systems for providing data are disclosed. An optimal set of subcarriers can be determined for a data transmission when a plurality of devices have requested the data transmission. The optimal set of subcarriers can be determined based on similarities or differences between parameters assigned to subcarriers in capability profiles. Capacity loss and other information can be determined based on the similarities or the differences among corresponding parameters of the capability profiles. The data transmission can be transmitted to the plurality of devices via the optimal set of subcarriers.

Optimizing resources in data transmission

Methods and systems are disclosed including a mobile device configured for initiating a communication session with a transceiver interface of a node that comprises a network interface. The node may be queried via the communication session for a status report associated with an error, and an instruction may be communicated to the node via the communication session instructing the node to perform an operation. Communication may be established with the wireless access point via the wireless network after communication of the instruction. The transceiver interface may be configured to communicate via a second network to address issues in the wide area network.

Data gathering for a node

Systems, methods, and apparatuses are described for coordinating wireless communication. Various devices may be configured for wireless communication. The wireless communications may be coordinated via a backhaul communication channel and may minimize interference between the communications.

Coordinating wireless data communications

Methods and systems for analyzing data are disclosed. An example method can comprise receiving a first data signal, decoding the first data signal, determining a second data signal based on the decoded first data signal, and determining a modulation error ratio based on a difference between the first data signal and the second data signal.

Data interpretation with modulation error ratio analysis

Systems, apparatuses, and methods are described for using one or more components of a device, such as a camera, to generate complementary heat for the device, such as a camera lens of the device. In one aspect this can be accomplished by activating the one or more components and/or by causing the one or more components to operate in a particular manner expected to generate heat. The generated heat may be instead of or in addition to heat generated by one or more dedicated heaters. The selected components may produce heat as an incidental effect for performing other functions of the device.

Device temperature control using device components

Provided are methods and systems for, in some aspects, mitigating interference over a communication channel. In an aspect, a device can be configured to detect interference and to dynamically reconfigure to avoid interference. Such a device can be configured to receive content over various communication channels and can intelligently select a communication channel to avoid interference.

Interference detection and remedy

A device (e.g., a security device, a video doorbell, a security camera, etc.) may receive an input voltage and based on the input voltage may determine the input power available to the device. The device may access various power level requirements associated with one or more functional components associated with the device. The device may then determine one or more functional components to activate or set to an active status on the device based on the input power available to the device, component power level requirements for one or more of the functional components, and other factors such as priority levels and preferences.

Methods, systems, and apparatuses for power management of a video doorbell

Methods and systems for managing communications among network devices are disclosed. An example method can comprise determining a time window for transmission based on a scheduling protocol. The scheduling protocol can specify time windows for using corresponding wireless protocols to transmit signals. Different wireless protocols can be associated with different time windows and different devices. A device can prevent transmissions during the time window, thereby allowing other devices to provide transmissions during the time window according to the scheduling protocol.

Network scheduling for improved reliability

Digital information can be carried on the fiber leg of an access network using binary modulation. Binary modulated data received at an O/E node can then be modulated onto an analog waveform using quadrature amplitude modulation or some other technique for modulating an analog waveform and transmitted over, for example, the coaxial leg of the network. The O/E node may also receive an analog signal, over the coaxial leg, modulated to carry upstream data from subscriber devices. The O/E node may demodulate the upstream signal to recover the upstream data and forward that upstream data over the fiber leg using a binary modulated optical signal.

Hybrid fiber coaxial node

Described herein are systems, methods, and apparatuses for determining an optimal path in a mesh network. A pre-emptive message, such as a request to send (RTS) message, carrying, for example, an address of a target mobile device, may be sent from an access point to a computing device in a mesh network. The computing device may relay the RTS to the target mobile device. A clear to send (CTS) message and transmission parameters indicating channel conditions may be transmitted from the target mobile device to the access point via the computing device. The access point may determine an optimal path based on the transmission parameters and send data via the optimal path.

Path optimization in a mesh network

Methods and systems for selecting routes from among multiple media and/or optimizing transmission across those media are described. A minimum data rate may be determined for transmitting a content item. Based on that minimum data rate, a device may determine whether to transmit the content item via a given medium, select a different medium for transmission, or adjust transmission to compensate for unfavorable network conditions. A device may select a medium based on ranking one or more routes from a content source to a user device. Further, a device may determine a data rate for transmission based on calculating an expected time of transmission that includes time spent performing retransmissions at a given data rate.
