Security by Design: Security should be a fundamental consideration from the initial planning stages of any wireless implementation. This ensures:

Risk Assessment: Identifying potential vulnerabilities early on.

Security Controls: Choosing appropriate encryption, authentication, and access control mechanisms.

Integration: Security measures are seamlessly woven into the system's architecture, not retrofitted later, which can be less effective.

LoRa: Refers to the physical layer chirp spread spectrum (CSS) modulation, enabling long-range, low-power communication.

LoRaWAN: An open MAC layer protocol that builds on LoRa, defining network architecture, device management, and data routing for large-scale LoRa networks.

Perception Layer: The foundation of an IoT system, it consists of sensors and actuators that:

Sense: Collect data about the environment or object being monitored.

Actuate: Potentially make changes based on commands (e.g., a smart valve opening/closing).

Transmit: Send gathered data to upper layers for processing.
