What is the quality signal strength for wireless networks that support voice and video?

For wireless networks that support voice and video, a signal strength of -67 dBm is generally considered to be optimal. This level of signal strength ensures a strong enough connection to support the bandwidth demands of voice over IP (VoIP) and video streaming applications, which are sensitive to latency and require stable data transmission.

At -67 dBm, the signal is robust enough to reduce the chance of packet loss, thus enhancing the overall quality of the calls or video streams. This is especially important in environments with many concurrent users or devices, where a strong signal can significantly mitigate issues like jitter and delay.

In contrast, a signal strength better than -67 dBm, such as -50 dBm, while technically better, may not be necessary for typical voice and video performance and could lead to issues with interference from other devices. Signal strengths below -67 dBm, such as -75 dBm or -82 dBm, become increasingly problematic for real-time applications, as they can lead to degraded performance, increased latency, and a higher likelihood of disconnections, making them unsuitable for voice and video services.
