CWISA-102 Exam Dumps : Certified Wireless IoT Solutions Administrator

• ZigBee Channel Spacing: ZigBee channels in the 2.4 GHz band are spaced 5 MHz apart. This helps manage interference in the crowded 2.4 GHz spectrum.

• Purpose of POC: A proof-of-concept (POC) validates the feasibility and potential value of a solution within its intended operational environment.
• Scaling: POCs are small-scale, allowing for quicker and less costly testing before committing to a full-scale deployment.
• Real-world Evaluation: Unlike manufacturer demos, a POC exposes the system to the unique variables (e.g., interference, usage patterns) present in the user's specific setting.

• LoRa: This refers to the underlying radio modulation technique using Chirp Spread Spectrum (CSS). It defines how data is physically encoded onto the wireless signal.
• LoRaWAN: This is the network protocol built on top of LoRa. It manages device communication, network topology, and aspects like security. It operates at the MAC sublayer of the Data Link layer (Layer 2) of the OSI model
• LoRa vs. LoRaWAN: Key takeaway is that LoRa is the physical layer technology, while LoRaWAN adds the networking layer for management.
