Unifi transmit power auto9/14/2023 5 GHz frequencies cause less interference and offer greater bandwidth, and thus higher bitrates. Reducing the power on 2.4 GHz frequencies may trigger many clients to move to the 5 GHz frequency, improving network performance – even in less-populated areas. Lowering power will reduce the issue, but may create the need for additional access points in some locations.Ĭlients are “steered” toward lower-interference frequencies Less interference, more access points neededĪs signals in 2.4 GHz frequencies propagate farther than 5 GHz signals, interference is a bigger problem on those channels. While different approaches exist, the one offering the biggest gain is to lower the power on 2.4 GHz channels. In this post, we focus on what you can do to tweak the performance of your access point, but the result will be impacted by what choices customers make. As many tests in our Wi-Fi house have shown, the influence of client behaviour on networks can be significant. Network performance is impacted by both clients and access point settings. The benefits of toning down 2.4 GHz channels If that user responds by upping the transmit power of his access point, the situation simply escalates. If the owner of the first access point decides to increase transmit power as shown in the lower figure, it will potentially create a larger region of high interference, decreasing network performance for the second user. The red region highlights the location where the interference is the highest, causing slowdowns for users. In the upper figure, both access points are transmitting at ‘normal’ power. When networks shout to be heard…īut if your neighbours follow suit and boost the signals of their own access points, network interference will occur on a larger scale, further impacting the Wi-Fi experience, as illustrated below: So, a logical way to improve the Wi-Fi signal would be to increase the transmission power of your Wi-Fi access point to ensure that it is “louder” than those of nearby access points. Your Wi-Fi-enabled device will select the strongest signal over weaker ones. Let’s start with some Wi-Fi basics: the basis for a good Wi-Fi network experience is a robust signal. In these locations, interference between overlapping networks was already an issue – and now, more than ever. This huge reliance on home internet services creates new challenges for Wi-Fi networks, especially in urban locations. The COVID-19 pandemic is forcing many people to work from home, causing a tremendous increase in data flows on access networks.
