Mesh over LoRa: The Power of Mesh Networking with the Reliability of LoRa Modulation

Mesh over LoRa is a cutting-edge wireless connectivity protocol that combines the scalability and robustness of mesh technology with the reliability and long range of LoRa modulation. This innovative protocol is born from the integration of NeoCortec's Neomesh firmware stack and Embit's powerful EMB-LR1121-e/mesh module, creating an unparalleled solution for your IoT applications.

Simplicity, Power, and Flexibility in a Single Solution

The Mesh over LoRa protocol leverages the decentralized intelligence of the Neomesh stack, eliminating the need for a central network coordinator. Every node in the network is autonomous, intelligent, and capable of routing data, ensuring a network that forms and maintains itself, regardless of its complexity or size. This unique architecture has been perfectly adapted for the hardware of our EMB-LR1121-e/mesh module, which integrates Semtech's LR1121 long-range transceiver and a powerful STM32U0x MCU.

Key Features of the Mesh over LoRa Protocol

Our protocol inherits the best features of both Neomesh technology and LoRa modulation, offering unique advantages for your applications.

Massive Scalability and Dynamic Architecture

Unlike traditional mesh networks, which are often limited to a few hundred nodes, Mesh over LoRa is designed for virtually unlimited scalability, supporting thousands of devices. Every device acts as both a sensor and a router simultaneously, creating a dynamic and self-configuring network infrastructure where all nodes have the same role. Adding a new device is as simple as turning it on: it will automatically join the network, strengthening it and extending its coverage.

Ultra-Low Power Consumption for Every Node

Thanks to time-synchronized operation, all nodes in the network can boast extremely low power consumption. Devices wake up only at predetermined intervals to communicate, remaining in a low-power sleep mode the rest of the time. This allows the entire network to be powered by small batteries for several years, a crucial feature for large-scale IoT applications.

Cable-Like Reliability

The combination of hop-by-hop handshakes, automatic retransmissions, and frequency hopping makes data delivery extremely reliable, even in challenging RF environments.

• Local Handshake: Every data packet is locally acknowledged between neighboring nodes, ensuring it is not lost during transmission.
• Frequency Hopping (FHSS): Transmissions occur across 15 different channels to avoid interference and noise, increasing system robustness.
• "SpeedRouting" Intelligent Routing: The patented algorithm always identifies the fastest and most reliable path for data delivery, dynamically adapting to network changes.

Security Built into the Protocol's Core

Security is a fundamental element.All wireless communication is protected by AES128 encryption and advanced mechanisms to prevent cyber-attacks.

• Full Encryption: All transmissions, including network beacons, are encrypted to protect data and network integrity.
• Playback Attack Protection: A challenge-response mechanism ensures the authenticity of every data exchange, making it impossible to re-inject malicious packets.

The EMB-LR1121-e/mesh Module: The Engine of Mesh over LoRa

The beating heart of our protocol is Embit's EMB-LR1121-e/mesh module. Compact and ultra-low power, it was specifically designed for this solution, offering long-range communication on both the sub-GHz (868/915 MHz) and 2.4 GHz bands. The use of LoRa® Spread Spectrum modulation ensures exceptional range and remarkable robustness against interference, bringing the benefits of LoRa into a flexible and powerful mesh topology.
