Range of Wifi 5 vs 6 vs 6e given max transmit power
Range of Wifi 5 vs 6 vs 6e given max transmit power
I believe most consumers in the USA have relied on Wi-Fi access points and routers operating at the maximum allowed power for years. This has led me to doubt any device claiming coverage of over 2,000 square feet. Considering both WiFi 5 and WiFi 6 operate on the 2.4 and 5 GHz bands, how much greater is their actual reach compared to WiFi 5? If we define effective range as mesh Ethernet backhaul performance with negligible packet loss or interference, and assuming a minimum speed of 50 Mbps per device, then 5 GHz connectivity likely offers shorter distances than 2.4 GHz. The information I found is limited and possibly unreliable when comparing mesh setups for different standards.
Regarding WiFi 6 versus WiFi 6e, the newer version pushes more data onto non-6 GHz channels, potentially extending effective coverage. This matters because if the current network falls short, upgrading to a newer protocol could be necessary. But without concrete data on real-world performance, it's hard to decide whether to upgrade or replace entirely.
Generally, higher frequencies travel shorter distances and are more easily blocked by obstacles. Wi-Fi 6 achieves longer reach because it supports the 2.4 GHz band (lower bandwidth but greater coverage, similar to Wi-Fi 4). Choosing 6E is mainly due to access to the 6 GHz spectrum which offers higher data rates at closer distances. The actual distance you can get depends on your home’s structure—such as wall thickness, wood content, metal presence, and internal wiring. Optimal router placement should be determined in person. For more details, see the article from Ars Technica.
The key points about WiFi networks in consumer networking are covered on the provided website. Essentially, as noted by @seanondemand, while WiFi 6E provides higher speeds in the 6GHz spectrum (when compatible devices are used), both WiFi 6 and 6E focus on enhancing stability in the traditional 2.4GHz and 5GHz ranges compared to older standards.
It restores at least 2.4Ghz functionality, and my performance on the band has improved from 25Mbit to 120Mbit. It appears to handle the current interference more effectively.
In summary, it seems Wi-Fi 6/6E could potentially boost network reliability at greater distances, though it might not offer a clear advantage over Wi-Fi 5 in most cases. The actual impact depends on factors like home construction. I’m checking if conditions stayed consistent before and after upgrading between the standards. That guide on AP placement is really useful, even if it’s a side point for my main concerns. I was also considering whether 2.4 GHz performance would improve with Wi-Fi 6, but it doesn’t appear to do so. Wow, the info is very detailed and clear—great job on explaining max speeds and MIMO importance. They explain why clients matter and how Wi-Fi 6 aims to manage traffic better in crowded areas, not necessarily a big jump in bandwidth or range.
I think this will only work if every vehicle uses WiFi 6; it won’t appear for years and not all gadgets are compatible. This technology is similar to other issues where not every access point offers the same capabilities, so features that help crowded setups often miss out on consumer products. WiFi 6 enhances data transfer on the 2.4GHz band by supporting 1024-QAM, which allows more information in the same range. It’s the first major upgrade for 2.4GHz since WiFi 4, which only handled 64-QAM. WiFi 5 was limited to 5GHz and used 256-QAM. WiFi 7 promises even better performance with 4096-QAM and the ability to switch between multiple frequency bands smoothly, improving roaming experience. QAM refers to how efficiently data can be packed into radio waves, while MIMO increases signal strength by sending multiple signals simultaneously. Together they boost bandwidth and range, though MIMO mainly helps with distance. QAM tends to lose effectiveness as distance grows, so you need to switch to less efficient methods. In short, expect a noticeable speed increase on 2.4GHz when switching to WiFi 6, but it will never match the speeds of 5GHz or beyond due to spectrum limitations.
It makes sense that Wi-Fi 6 performance on the 2.4 GHz band could boost throughput due to improved efficiency. Keep in mind, higher-order modulation schemes need closer proximity or stronger signal (~-55 dB at 20 MHz channel), so this gain would likely appear only near the access point according to Duckware.
Very intriguing, I had no idea about the details but it’s logical that it depends on packet size. You’re right—don’t want to waste spectrum padding smaller packets into bigger frames, which is why most devices limit the data rate for broadcast traffic. This helps maintain the longest range possible. It makes sense that some gadgets let you adjust the SSID broadcast frequency, and newer models usually set it low by default. With clients scanning at a reduced speed too, to conserve energy, modern hardware can sometimes take a while to recognize 5GHz networks. DFS might also contribute to this delay.
