Enabling Scalable, Secure, and Reliable IoT Networks with IPv6 Sub-GHz Mesh over LoRa™ PHY
Introduction
The rapid proliferation of Internet of Things (IoT) devices demands a communication infrastructure that is scalable, secure, and reliable. Northern Mechatronics introduces NM Mesh Connect™, an IPv6 Sub-GHz mesh technology available on NM1801xx that combines the vast address space and hierarchical routing of IPv6 with the long-range, low-power capabilities of LoRa™ technology. This document explores the technical aspects, benefits, and applications of NM Mesh Connect™, offering a game-changing solution for IoT networks.
Overview of IPv6 and LoRa™ PHY
IPv6
IPv6, or Internet Protocol version 6, is the most recent version of the Internet Protocol (IP). It is designed to address the limitations of its predecessor IPv4. IPv6 offers a vastly larger address space, improved routing efficiency, and enhanced security features. IPv6’s hierarchical addressing scheme simplifies the management and routing of IP addresses, making it ideal for low-power IoT device deployment in challenging wireless environments where traditional star-topology networks such as LoRaWAN™ struggle.
LoRa™ PHY
LoRa™ (Long Range) is a proprietary wireless communication technology developed by Semtech Corporation. Operating in the sub-GHz unlicensed ISM frequency bands (typically 868 MHz in Europe and 915 MHz in North America), LoRa™ enables long-range communication with low power consumption, making it suitable for IoT applications such as environmental monitoring, smart agriculture, and asset tracking. The PHY layer of LoRa™ defines the modulation, transmission, and reception of radio signals, ensuring reliable and efficient data exchange.
NM Mesh Connect™
Northern Mechatronics’ NM Mesh Connect™ integrates IPv6 and LoRa™ PHY together to deliver a powerful communication framework that leverages the strengths of both technologies. This combination allows for the creation of sub-GHz mesh networks capable of supporting many IoT devices in challenging wireless environments or over extensive geographical areas.
Key Features
- Scalable: NM Mesh Connect™ allows devices to communicate directly or through intermediate nodes, enhancing network resilience and coverage. NM Mesh Connect™ allows up to 64 hops enabling coverage in large commercial or industrial complexes, agricultural fields, or remote sites with minimal infrastructure.
- Secure: IPv6 includes IPsec (Internet Protocol Security) as a mandatory component, providing end-to-end encryption and authentication for data packets over multiple hops. NM Mesh Connect™ includes application layer security keys that provide additional data privacy allowing multi-tenet deployments with overlapping wireless coverage.
- Reliable: Mesh networking provides redundant communication paths allowing data packets to be routed reliability to the destination. NM Mesh Connect™ also implements Link Layer acknowledgment that enables reliable UDP communication with minimal overhead.
- Low-Power: Not only do devices running NM Mesh Connect™ benefits from the long-range and low-power capabilities of LoRa™ PHY, but NM Mesh Connect™ also possesses continuous dynamic link-metric optimization capability that ensures packets are always routed through a path with the lowest energy cost.
