Wireless network performance are often affected by a selection of the wireless channel by a person. Wireless network performance is often hindered by interference from other wireless networks. A person may experience slow internet speed or bad video call performance due to much wireless networks using the same channel for data trasmission.
The 5GHz wireless band contains more available frequency channel than the 2.4GHz band. Furthermore, data speed are also higher on the 5GHz band because there is more spectrum available to the wireless networks using that particular band. The 5GHz band is divided into segment called UNII bands.
How to choose the best Wi‑Fi channel
These bands has specific purposes. Some UNII bands is created for use within the indoors to provide reliable signals to the device within the indoor area. However, other UNII bands have higher power limits if a person choose to use these bands outdoors.
A person need to be aware of these bands because these bands will dictate the available channels for the wireless router. Channel bonding are the process of combining multiple channels into one channel. By bonding channels, a person can increase the available bandwidth for the wireless device.
A person can begin with a 20MHz channel. However, a person can also bond channels to create either a 40MHz or 80MHz channel. Channels that is 80MHz allow for faster data transfers.
However, the wider the channel, the more likely that other wireless network will interfere with the wireless signal. Dynamic Frequency Selection, or DFS, is a set of rules that will automatically require that a wireless router avoid using certain channels if it detect radar signals. Many wireless channels are set to be DFS channels.
Wireless routers use these channels less often because they will automatically avoid these channels to prevent interfering with the radar signals. If a wireless router detects a radar signal on a DFS channel, the router will automatically change the wireless connection to a different channel. This change may cause the user to experience an interruption in there wireless connection.
A person should select non-DFS channels if a person needs a continuous wireless connection to perform online activities that require high level of connection. A person may select DFS channels if a person need higher data capacity. However, a person must also consider the different regional settings for wireless channels.
Different country have different wireless frequency laws. A person that sets the wireless router to the wrong region may prevent the wireless router from using some of the available channels or may limit the signal power of the wireless router. The 2.4GHz wireless band is different than the 5GHz wireless band.
The 2.4GHz band can travel further and pass through walls more easy. However, the 2.4GHz band is often crowded with other wireless device such as microwave ovens or baby monitors. For this reason, 2.4GHz wireless bands are often slower than 5GHz bands.
A person should assign IoT device to the 2.4GHz band. However, they should assign laptops or device that require high-speed data to the 5GHz band. A person can improve the wireless network performance by manually selecting the wireless channel.
To do this, a person can use a wireless scanning application to view which wireless channels other wireless networks in the area is in use. A person that lives in an apartment may want to avoid channels that are very wide such as 80MHz because these channels will overlap with other wireless channels. These overlapping channels will interfere with the wireless performance of the network.
When a person purchase new hardware, they should look for wireless routers that support WiFi 6 technology and have good 5GHz capability. Another option that a person can use is a mesh WiFi system. These systems provide better wireless coverage in larger areas because they have multiple node for the wireless signal.
A person must also be aware of the need of the wireless network. A wireless network require attention from the user. Periodic check on the wireless channels will help ensure that the wireless network continues to be efficient.
