Executive Summary
This standard describes a narrowband transponder for broadband CATV amplifiers that uses a Frequency Shift Keying (FSK) physical (PHY) layer and a LoRaWAN media access control (MAC) layer.
The suite of narrowband transponder specifications includes:
- SCTE 25-1 describes a Physical Layer for a narrowband transponder.
- SCTE 25-2 describes a MAC Layer for a narrowband transponder.
The SCTE also maintains a suite of information models (e.g., SCTE 283) and data models for devices which are connected to the coaxial cable network via a transponder.
Additionally, the CableLabs Remote PHY specification [R-OOB] provides information on carrying signals, such as this narrowband transponder, over the Remote PHY architecture.
Scope
This specification describes interface requirements for a narrowband transponder based on LoRaWAN technology.
Electromagnetic Compatibility (EMC) is not specified in this standard and is left to the vendor to ensure compliance with local EMC regulatory requirements. Other physical parameters such as shock, vibration, humidity, etc., are also not specified and left to the vendor’s discretion.
Benefits
This document describes a narrowband transponder used with devices attaching to a coaxial cable network. The narrowband transponder will allow devices connected to a coaxial cable network to communicate with users, applications and other resources provided by the network operator. This connection will allow remote configuration, access to telemetry and alarms, and long-term support making the coaxial cable network more reliable by providing proactive information about the state of the device with the transponder.
The impact on the broadband industry will be more reliable networks and higher customer satisfaction.
Intended Audience
The intended audience for this document includes cable operators, suppliers and other parties interested in both cable technology and connected devices.
