  • Publication number: 20230396903
    Abstract: Apparatus and methods for unified high-bandwidth, low-latency data services provided with enhanced user mobility. In one embodiment, a network architecture having service delivery over at least portions of extant infrastructure (e.g., a hybrid fiber coax infrastructure) is disclosed, which includes standards-compliant ultra-low latency and high data rate services (e.g., 5G NR services) via a common service provider. Premises devices are used to provide the 5G-based services to users at a given premises and thereabouts. In another variant, local area (e.g., “pole mounted”) radio devices are used to provide supplemental RF coverage, including during mobility scenarios. The 5G-capable network enables uninterrupted and “seamless” exchange of data at a client device by utilizing a common waveform protocol (e.g., 3GPP-based) at a premises device and an external radio device to communicate with a client device at different locations and times while the device is moving between inside and outside the premises.

  • Patent number: 11824760
    Abstract: Both wireless communication and communications via a cable modem are supported between a network node and a customer premises. Alternative communications links provide redundancy and the possibility to take advantage of the different types of links capacity to provide a level of service that would not be possible using a single communications link to a customer premises. In various embodiments a network node, such as a cable network node hubsite, has an optical connection to the Internet or another communications network and provides network access to one or a plurality of customer premises. The network node includes a wireless access point, e.g., pole mounted base station, as well as one or more cable modem interfaces to thereby allow for both wireless and cable modem based communications. This allows for packets of different applications to traverse different links and/or to switch between links in the event of maintenance or reliability issues.

  • Publication number: 20230370315
    Abstract: Various embodiments comprise systems, methods, architectures, mechanisms and apparatus for spatially combining a plurality of 5G new radio (NR) carrier signals or channels for transport via a common frequency channel through a hybrid fiber coax (HFC) or other communications medium link or network. To overcome a loss of receiver ability to discriminate/process individual spatial components, each baseband signal and/or carrier signal including a spatial component has imparted to it a respective channel component Øn configured to modify amplitude, phase shift, and/or time delay of the baseband signal and/or carrier signal such that multiple spatial component bearing signals stacked/combined within a HFC frequency channel or slot include channel characteristics sufficiently distinct so as to enable a receiver to identify, discriminate, and otherwise process desired spatial components.

  • Publication number: 20230144753
    Abstract: Apparatus and methods for content fragmentation, distribution, protection, and re-constitution within a content distribution network. In one embodiment, the apparatus and methods enable distribution of content fragments to edge nodes (which may include user or subscriber CPE), thereby enabling edge networks or membership groups to be established wherein content can be shared solely at the edge. In one variant, high data bandwidth, symmetric uplink/downlink, low latency PHY links (e.g., 5G NR-compliant wireless interfaces) between the edge nodes participating in the edge networks or membership groups are used such that particular quality of service/experience performance requirements can be met. Distribution of the fragments also advantageously enhances redundancy and security.

  • Publication number: 20230050403
    Abstract: Apparatus and methods for guaranteeing a quality of experience (QoE) associated with data provision services in an enhanced data delivery network. In one embodiment, a network architecture having service delivery over at least portions of extant infrastructure (e.g., a hybrid fiber coax infrastructure) is disclosed, which includes standards-compliant ultra-low latency and high data rate services (e.g., 5G NR services) via a common service provider. In one exemplary implementation, “over-the-top” voice data services may enable exchange of voice traffic with client devices in the aforementioned network. A distribution node may use a detection rule to identify received packets as voice traffic, and cause a dedicated bearer to attach to the default bearer, thereby enabling delivery of high-quality voice traffic by at least prioritizing the identified packets thereafter and sustaining the delivery even in a congested network environment, and improving the quality of service (QoS) and QoE for the user(s).

  • Patent number: 11515919
    Abstract: Methods and apparatus for facilitating the use of a plurality of antenna beams for communications purposes are described. In at least some embodiments beam priority information is periodically exchanged. Multiple timers are used to ensure beam information is exchanged at intervals intended to facilitate reliable beam synchronization and to control switching to one or more alternative beams in a predictable manner in the event beam change information or beam synchronization information is lost. In some but not all embodiments a wideband beam is used to communicate beam synchronization information when synchronization using narrower beams used for normal data communication is lost.

  • Publication number: 20220329453
    Abstract: Apparatus and methods for displaying data in an immersive environment wherein sensor (e.g., IoT sensor) data is aggregated via a gateway and various different types of air interfaces depending on application and location (e.g., LoRa, Wi-Fi, 5G NR, C-band, 60 GHz, CBRS, etc.), aggregated at a cloud service, processed through an analytics platform, and transmitted to a UI platform for display on a user interface. One implementation of displaying the sensor data comprises overlaying the sensor data in virtual reality in an immersive video wherein the video is a live stream from a 360-degree 8K camera. A user may interact with the overlaid sensor data within the user interface in a virtual environment to change settings to a desired degree. Artificial intelligence and machine learning may automatically suggest actions to the user or change settings based on sensor data.
