Question:

“Is NetInfo capable of measuring the signal strength of Wi-Fi networks?”

Answer:

NetInfo is a versatile tool that provides a wealth of information about network connections, but when it comes to measuring the signal strength of Wi-Fi networks specifically, its capabilities can vary depending on the platform and the specific implementation of NetInfo being used.

In some cases, NetInfo can indeed provide insights into Wi-Fi signal strength. For instance, on mobile platforms like Android and iOS, NetInfo may offer APIs that return a level of detail regarding the connection quality, which can indirectly reflect signal strength. These APIs typically categorize the connection quality into levels such as poor, good, excellent, etc., based on the signal strength and other factors.

However, NetInfo is not a dedicated signal strength meter. It does not provide a precise decibel-milliwatts (dBm) measurement that you would get from specialized Wi-Fi analyzer tools. For users who need to perform detailed signal strength analysis or site surveys, standalone Wi-Fi analyzer apps or built-in operating system utilities would be more appropriate.

In summary, while NetInfo can offer a general indication of Wi-Fi connectivity quality, it should not be relied upon for accurate signal strength measurements. For those requirements, dedicated tools that are designed for signal strength measurement should be used. NetInfo remains a valuable tool for a quick check of network status and type, but for in-depth analysis, look towards tools specifically crafted for that purpose.
