CWISA-102 Exam Dumps : Certified Wireless IoT Solutions Administrator

• 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.

References:

• LoRa Modulation: Technical explanations of Chirp Spread Spectrum (CSS).
• LoRaWAN Specification: Official documentation detailing the network architecture and MAC layer functions.
• OSI Model: Descriptions of the Data Link layer and its role in networking.

• HTTP's Popularity: HTTP is the foundation of the web, making it widely known and supported. Developers have extensive familiarity with its concepts (methods, headers, status codes, etc.).
• REST APIs and Webhooks: These often leverage HTTP for communication, building upon existing knowledge and tools.
• Tradeoffs:

References:

• REST APIs: Overviews of their use of HTTP, demonstrating its prevalence in API development.
• Developer Experience with HTTP: Discussions on the familiarity with and availability of HTTP libraries in various programming languages

• Capacity Planning: The number of devices a wireless network can support is the primary determinant of its required capacity. This is because:
