Introduction This document provides a YANG module description for managing a LoRa endpoints. SemTech [LoRa] (c) is a low-rate, low-power, long-range radio technology. It could be used as a base radio technology for building Low-Rate Wide-Area Networks (LR-WAN), also known as LPWA (Low-Power Wide Area). SemTech [LoRa] (c) has the following characteristics: o Works in narrow, license-free (ISM) bands with good propagation properties (< 1GHz) o Low- to very-low throughput (270 bps--200 kbps) o Low-power operation (25 mW in Europe) o Far-Reaching communication capabilities (20 km with line-of-sight, several km in urban environment) o Strong channel access restrictions (1% to 10% duty cycling) The management of LoRa-based devices can be done through a standard approach, compatible with the best network-operator practices, namely NETCONF or RESTCONF. A formal definition of the parameters and the values to be managed is thus required, which can be done with the YANG module language. The following document presents a YANG module definition for managing a LoRa-based end-device. Pelov, et al.

Requirements Language The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in RFC 2119 [RFC2119]. 2. LoRa Data Model The data model has the following structure for Lora configuration: +- RW lora +- RW Lora Device +- RW Mode | +- RW Channel Bandwidth enumeration | +- RW Coding Rate enumeration | +- RW Spreading Factor int8 +- Physical Layer | +- RW Preamblelength int32 | +- RW Channel Frequency Range enumeration | +- RW Channel int8 | +- RW SymbolTimeout int32 +- MAC Layer +- RW FrPayloadEncryption boolean +- RW Delay int32 +- RW FixlengthPayloadOn boolean The data model defines a state container Mode which include the three principal characteristics of the LoRA interface which determine the parameters of the channel Figure 1 3. LoRa YANG module This model imports typedefs from [RFC6991]. file "ietf-pelov@2015-10-10.yang" module lora { namespace "urn:lora"; prefix lo; import ietf-interfaces { prefix if; Pelov, et al.
