CWISA-103 Exam Dumps : Certified Wireless IoT Solutions Administrator(2025 Edition)

60GHz Absorption: The 60GHz band experiences significant signal attenuation due to absorption by oxygen molecules in the atmosphere. This severely restricts the usable range of wireless systems operating in this frequency.

Why Other Options Don't Apply:

Atmospheric Scattering: Impacts longer wavelength transmissions, less significant at 60GHz.

Solar Radiation: Can cause interference on some frequencies, but not a primary range limitation at 60GHz.

Rain Fade: Primarily affects higher frequencies (above 10GHz), but its impact is less severe than oxygen absorption at 60GHz.

Browser Ubiquity: JavaScript has a native runtime environment within almost every modern web browser, making it the 'built-in' scripting language for web-based interfaces.

Node-RED: This IoT flow-based programming tool specifically uses JavaScript for its logic and automation functions.

Other Languages:

PHP: Primarily server-side for web applications

Python: Versatile language, used in some back-end IoT functions but not natively in browsers

R: Statistical and data analysis, not typically embedded in wireless solutions

Customization and Integrations: The presence of APIs often suggests a system is integrated with other platforms or has custom-built elements.

Understanding Dependencies: Documenting used APIs helps clarify how different parts of the system interact and where potential issues might arise.

Troubleshooting Efficiency: Detailed API documentation aids in resolving problems, allowing staff to assess interconnected systems effectively.

Knowledge transfer: Future support teams won't have to reverse-engineer the system; documentation ensures smooth handover and understanding.
