LoRa Device-to-Device Communication Test Report – MacTalk
Scope
This report defines the scope of real-world field testing and performance validation of MacTalk, Macnman’s proprietary LoRa-based device-to-device (D2D) communication framework, designed to enable direct, secure communication between LoRa devices without gateway dependency during active data exchange.
The primary objective of this testing is to evaluate direct LoRa device-to-device communication performance, including range, reliability, latency, and security behavior, under practical deployment conditions. The tests focus on validating peer-to-peer communication stability while enforcing an additional proprietary security layer beyond standard LoRaWAN mechanisms.
The scope of this report includes:
- Validation of direct LoRa device-to-device (D2D) communication without reliance on a LoRaWAN gateway
- Measurement of communication range, RSSI, and SNR between peer devices
- Evaluation of packet delivery reliability and latency in D2D mode
- Verification of MacTalk proprietary security layer, including:
- Secure device pairing and authentication
- Encrypted payload exchange
- Rejection of unauthorized or unknown devices
- Analysis of communication performance under indoor, urban, and open outdoor environments
- Assessment of operation under Indian environmental conditions, including temperature and humidity variations
- Comparison of MacTalk D2D communication behavior versus traditional gateway-based LoRaWAN communication (where applicable)
The testing was performed using Macnman LoRa devices running MacTalk firmware, ensuring the same hardware platform was used consistently across all test scenarios to provide comparable and repeatable results.
This report is intended to support:
- System integrators designing localized, low-latency LoRa communication
- Enterprises requiring secure device-to-device communication without continuous network dependency
- Industrial and infrastructure deployments needing autonomous operation and fallback communication
- Customers evaluating MacTalk as an alternative or complement to gateway-based LoRaWAN networks
The findings from this report provide practical guidance on deploying, securing, and scaling LoRa device-to-device communication using MacTalk in real-world environments.
