12/24/2023 0 Comments Transmit power wifi![]() IOS devices switch base stations when the signal drops below -70 dBm and macOS below -75 dBm. Many end user devices are unwilling to switch base station even though a better base station appears nearby. Wi-Fi base stations are passive and the end users' devices control when to switch to another base station (GSM is the opposite and there the base stations decide which one handles each end users' device). In a crowded environment excessive base station transmit power does not increase speed because if it hears other base stations, it shares transmission time with them. Wi-Fi is bi-directional so there is no benefit if the mobile device sees the base station but not vice versa. ![]() On the other hand, mobile devices typically use 15 mW (12 dBm) to save power. I did some homework, please comment, if necessary: So now AirPort 2.4 GHz SNR (34 dB) is slightly better than Huawei (28 dB) and the most distant spot upstairs still seems to have decent coverage from both. I noticed that downstairs both base stations had about the same SNR which seems unnecessary so I now lowered Huawei's transmit power from 100% to 40% which might correspond to 40 mW (there are options for 40-60-80-100%). A switch might allow me to place it elsewhere but I try to avoid getting extra gear. Huawei is in a somewhat suboptimal place quite near the AirPort but the adjacent household Ethernet lines make this an easy spot for it. Huawei is upstairs and the AirPort downstairs. I have tested a few days Roaming Network (Ethernet-connected Wi-Fi base stations) with a primary mobile Huawei Lte CPE B593s-22 4G and AirPort Extreme 802.11n 5th Generation to extend it. Effective Isotropic Radiated Power (EIRP) 100 mW (20 dBm) 2,4 GHz and 200 mW (23 dBm) 5 GHz. Many Wi-Fi base stations by default use full transmit power i.e. Is it still possible or useful to tweak it somewhere? What transmit power does AirPort use for 2.4 GHz? 100 mW?ĪFAIK older AirPort Utility allowed 10-25-50-100% transmit power.
