The internal electronics will select and adjust the antenna use to get the best performance. Opens a new window it has 10 internal antennas with none available for movement by the users. And the vendors publish to which regulations they claim to comply.Īccording to the spec. So you may lookup such maximum for WLAN routers for different frequency bands at your public regulator. But public regulators provide specifications of maximum sending power for different frequency users. I seldom see power supply per frequency or per channel published. And the sending power per frequency is lower than the power supply. But again, they seldom publish a graph of maximum power supply over various factors as such power supply often is not constant. It is usually also printed on the power supply itself. And as far as power is concerned, all publish the power of the power supply of their devices. This does not imply that they provide graphs of dBm over channel or frequency. So you may need to lookup model product descriptions at shops or at Internet. As far as I can see, most vendors publish their models dBm in their product descriptions although not always printed on the outside of their product box. so is there a way to know the router signal maximum power before, preferably, its purchased? The dBm value of the router is something similar but I don’t see it to be said in the vendor’s router specifications.

So there is not a single value but a larger set of values if you categorize frequencies according to channels. And sure, you've to do such metrics per frequency resp. I don't know if this time is measured in seconds or milliseconds. You may measure how quick a router is in determining and applying such regulated conflict resolutions. and the regulative priorities and the abilities of your WLAN router how quickly to determine kind and source of such other signals and apply regulative constraints. Then you have the regulative need to determine presence of other signal sources like baby phones, RC, amateur radio.

But with modern WLAN routers, the situation is not as simple, for at least a decade as Peter has already indicated. WiFi signal strenght is measured in dBm as others have already written.
