5 GHz: Delivers faster speeds and offers less-crowded channels.2.4 GHz: Delivers slower speeds and more interference, but broadcasts further due to better signal penetration through solid surfaces.Here’s a simple breakdown of the two currently supported bands: Soon, we will launch the U6-Enterprise which will support the upcoming 6 GHz standard and deliver the fastest possible WiFi speeds. UniFi APs currently only support the 2.4 and 5 GHz bands. Use Band Steering to Move Compatible Clients to 5 GHz If you have a high-density deployment or high utilization, we recommend reducing your channel widths. Larger channel widths result in more interference. UniFi Network supports the following channel widths: High-density or crowded RF environments with a large channel width can decrease network performance and cause more device disconnections. Increase widths cautiously, though, as this will decrease your WiFi range and could increase channel interference.
Doubling your channel width will nearly double your wireless speed. Larger channel widths allow for faster speeds. Recommendations Increase Your Channel Width In general, it is safe to assume that you are in good shape if you are achieving ~50% of your theoretical maximum speeds. This applies to all vendors and wireless access points. This means that a 1 Gbps wireless connection can only support a simultaneous upload/download speed of 500 Mbps.įurthermore, wireless protocol overheads typically result in 25-40% speed reduction compared to the theoretical maximum. Unlike wired connections that support full-duplex communication, wireless communication is half-duplex. As such, your most pressing concern should be achieving stable speed and bandwidth rates that reliably support all connected devices. Achieving the highest rate possible isn’t required to ensure quality connectivity. For context, streaming Ultra HD content on Netflix only requires 25 Mbps of bandwidth. This article will explore the most common causes of slow speeds and provide suggestions for improving them.īefore you continue, please note that maximized speeds are not the ultimate benchmark of a high-performance network. Wireless throughput is affected by more than just how you configure your network and UniFi Access Points (APs).
Follow these guidelines, and those in Optimizing Wired Network Speeds, to maximize your total network throughput. Check out our UniFi Expert's Corner video for a quick overview of wireless speeds.
