Transmit Power Part 1: APs, Clients, EIRP and Why More Power Is Not Always Better
Transmit power is one of those wireless settings that looks simple at first. More power should mean better Wi-Fi, right? Not always. In Wi-Fi, increasing the transmit power of an access point can improve what the client hears from the AP. But that does not automatically improve what the AP hears from the client. Wi-Fi is bidirectional. Both sides of the conversation matter. This post looks at AP transmit power, client transmit power, EIRP, antenna gain, receive sensitivity, and why a “loud AP” can sometimes create more problems than it solves. ...
