It is used for military stations and any type of sensitive communication. It is not recommended to use this channel, even if you have a device that supports it. One more thing that you should keep in mind is that the regular smart devices as well as the smart home appliances also use the UNII-1 channel for communication.
Therefore, you might experience some interference between your router and these devices. The only solution for this is to make sure that your router is placed far from any smart devices like smart home appliances and smart bulbs. Another issue worth keeping in mind is congestion. Since it is clear that the UNII-1 band is highly suitable for WiFi, almost all the devices at your home will be connected to the internet via this band.
This may lead to congestion because of which there might be a drop-in the WiFi performance. To handle this, you can use various types of WiFi analyzer apps on the internet. These apps check for channel congestion in your vicinity and the best channel for you. This way you can get the best performance out of your wireless connection. Which brings me to my next point, how to find which one is suitable for you? Noise Noise Floor refers to the summation of all the unwanted signals and sources of noise within the range of your connection.
On the other hand, the Noise value should have a low number. But for both of these numbers, you have to remember that the value is negative. You can remember the thumb rule that the RSSI value should be closer to zero.
But for Noise, the reverse is true. Think of it like the channel having a Noise value furthest from zero is better. The higher this ratio, the better the WiFi connection is.
This window shows a complete overview of the analysis of the WiFi channels in the area as well as the best WiFi channel in the area of your router. Even though the window will have a suggestion for the best channel, it is better to make some calculations and find out on your own which channel is the best.
By now, you know that the best channel is one that has the best SNR value. In the case that you own a dual-band router, you can switch to a different WiFi frequency band by accessing your router's setting page using the same process as described above. In the same spot as where you see the band your router is using, you should also see an option to choose the other WiFi frequency band to use. Before you go ahead and change your router's frequency band, it may be worthwhile to check out MetaGeek's guide for designing a dual-band wireless network!
WiFi frequency bands: 2. Samantha Albano on April 1, What are WiFi frequency bands? How are 2. There are four main differences between the 2. In the 2. WiFi network speed — The higher frequency 5 GHz band makes up for its shorter range with much faster WiFi speeds than the 2.
To compare, the 2. Of course, the kind of router you have will better dictate the WiFi speed you can achieve. If the wide channel will respectively increase the transmission speed i.
In practice the power consumption will increase somewhat due to retransmissions. Especially in noisy environments or with lots of APs. Wide channels pick up noise on the whole channel width. Narrow channels pick up less noise. If there are many APs within reach, then it is better to assign each AP a separate channel.
There are twice as many 20MHz channels than 40MHz channels. Compatible user devices should be steered to 5GHz since there is more capacity and less interference. The simplest way is to turn down the transmission power of the 2. You just need to plan the channel use not to cause overlaps. Even if the original channel plan is perfect, DFS may cause unexpected channel switches causing overlaps.
If you have a quiet environment and your devices support them, you may use 80MHz channels. If you want to use the wider channels you have to live with DFS restrictions. Thank you so much for all your generous sharing. If set to 40MHz then devices would always wait for both channels to clear before transmitting.
The extension channel can be above or below the primary channel, there is no rule. The primary channel is mandatory and the extension channel has to be next to it. Yes, you can always use 20MHz channel width and often you should. With narrower channels you have more channels to choose from, which is great for dense installations, say a big lecture room with multiple APs.
With narrow channels you also get less noise, better sensitivity and more transmit power if you need it. There are many benefits. You should only use 40MHz for heavy file transfers or other high-bandwidth applications. The disadvantages of wide channels become even more apparent with 80MHz channels or let alone MHz.
This is very difficult to explain to customers, who believe they have paid for 5Gbps throughput. Thank you sir, my utmost gratitude for the effort of your team, i am a regular visitor to your website indeed, i thought to, out of courtsey provide some suggestion and feedback of my own , would be thankful if you could reply or acknowledge my recommendations to make this website more content focused.
Hi Petri, Really great posts on your site. I noticed one thing, which might not be correct, or I do not know well. According to the standards you can choose your primary channel freely and specify the extension channel above or below the primary. You can easily create a mess.
Many Fortunately only MikroTik lets the user choose. Very few vendors use them, though. It is impossible to say based on the given information. If you get started experiencing problems, consider examining your connection once more and converting to any other channel.
Should that no longer work, then the above tools and pointers will have to information you to the 5GHz channel that will make the most of your swanky modern router. If you get started to have issues along with your router, try these troubleshooting steps to briefly recover connections.
