Question

A county WLAN standard requires documenting client signal in dBm rather than signal bars. Why is that requirement reasonable for a technician?

Accepted Answer

Absolute dBm supports cross-device comparison better than vendor-specific bars or RSSI alone. — Bars are each gadget's emoji for "kinda okay," and they do not travel well between brands. County docs that demand dBm want numbers you can compare desk to desk. Same seat, same story — that is the point of absolute levels.

Answer

Signal bars are an IEEE absolute unit that already matches every laptop brand.

Answer

dBm documentation is only useful outdoors and has no meaning for indoor clients.

Answer

Bars automatically include channel utilization, so dBm adds no troubleshooting value.
