Gateway apparatus and methods for providing data services (including IoT data services) which leverage existing managed network (e.g., cable network) infrastructure. The disclosed methods and apparatus enable, among other things, delivery of IoT data services in a unified manner via a common portal or IoT gateway (IoTG) which may be both remotely accessed by a user, and remotely controlled/configured by the host network operator (e.g., MSO). In one variant, the premises devices include RF-enabled receivers (enhanced consumer premises equipment, or CPEe) configured to receive (and transmit) OFDM waveforms via a coaxial cable drop to the premises, and interface with the aforementioned IoTG to enable provision of both 5G high-speed data services and lower bandwidth IoT services to the premises, all via a single coaxial cable drop in the exemplary embodiment.
