US 11,832,034 B2 · Apparatus and methods for coordinated delivery of multiple data channels over physical medium

Abstract

Apparatus and methods for unified high-bandwidth, low-latency data services. In one embodiment, a network architecture having service delivery over at least portions of extant infrastructure (e.g., a hybrid fiber coaxial 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 variant, parallel MIMO data streams supported by 3GPP 5G NR are shifted in frequency before being injected into the single coaxial cable feeder, so that frequency diversity (instead of spatial diversity) is leveraged to achieve the maximum total carrier bandwidth that 3GPP 5G NR chipsets. Intermediate Frequencies (IF) are transmitted over the media in one implementation, (i.e., instead of higher frequencies), and block-conversion to RF carrier frequency is employed subsequently in the enhanced consumer premises equipment (CPEe) for 3GPP band-compliant interoperability with the 3GPP 5G NR chipset in the CPEe.
