Observability, security, and capacity of Wi-Fi versus 5G

When considering general-purpose wireless technologies for a new architecture, the decision is typically 802.11x-based Wi-Fi or 5G. When both are available, which one makes the most sense is usually driven by the observability, security, and capacity needs of the application in question.

Observability

Wi-Fi networks, typically deployed in confined areas such as homes or offices, face challenges related to interference, especially in densely populated environments. Observability can be hindered due to overlapping channels, signal interference from physical obstacles, and the presence of multiple devices competing for access. Tools for Wi-Fi observability, such as network analyzers, provide insights into network health but are expensive, and the onus often lies with local administrators to monitor and maintain optimal performance.

These tools were developed in response to needs in the field, in most cases long after the...
