CWSA (Solutions Administrator) CWISA-103 Exam Questions and Answers PDF

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.

Legacy Support: The primary reason to continue using older wireless technologies is the need to connect with devices that don't support newer standards (e.g., old sensors or equipment).

Other Reasons (Not as Strong):

Cost: Replacing legacy devices can be expensive.

Reliability: Some legacy technologies might be well-proven in specific settings.

Outsourcing Knowledge Transfer: When outsourcing implementation, the service provider has firsthand knowledge of system setup and configuration. Clear documentation ensures this knowledge remains accessible to you after the project is complete.

Ongoing Support: While paid/free support options influence long-term maintenance, they won't substitute missing documentation about the specific setup.

Reducing Future Vendor Reliance: Detailed documentation helps mitigate over-reliance on the service provider for minor changes and troubleshooting, giving you more long-term autonomy.

Proof of Concept: A POC typically happens before outsourcing, and focuses on validating the solution's feasibility, not ensuring smooth knowledge transfer thereafter.

Requirements Drive Decisions: The decision between wired or wireless must align with the solution's overall purpose, performance targets, and operational constraints.

Key Considerations:

Reliability: Does the application require guaranteed connectivity? (Wired may be favored).

Installation Cost: Can extensive cabling be done, or is it prohibitively expensive? (Wireless may be favored).

Flexibility and Scalability: Is node placement likely to change in the future? (Wireless may be favored).

Other Factors are Important, But Secondary: Distance, PoE availability, specific applications all matter, but they are assessed within the context of the overarching business needs.
