WiFi 6 is the latest generation of wireless technology, and it was specificaly design to handle the number of devices that is connected to a single network. Many home have alot of devices that require access to the wireless network. When many devices is connected to a network and all of them are using the network simultaneous, the network can begin to become congested.
Data congestion can make it seem like a wireless network have slow speeds or that the devices cant maintain a consistent wireless connection. WiFi 6 was developed to address these issues regarding data congestion with its implementation of more efficient methods for transmit data to numerous devices. WiFi 6 use three different frequency bands to distribute the data to the wireless devices within the network.
How WiFi 6 Improves Home WiFi
The bands include the 2.4 GHz band, the 5 GHz band, and the 6 GHz band (which is only available on WiFi 6E routers). The 2.4 GHz band provides the longest range to the wireless devices, but there are more instance of interference with other wireless devices using the same frequency. The 5 GHz band provides faster speeds then the 2.4 GHz band, but it has a shorter range.
Finally, the 6 GHz band offer the most available bandwidth to the network and experiences less interference from other devices on the wireless network, but it has the shortest range of the three bands. By implementing these three different bands, WiFi 6 is able to distribute the data to the wireless devices more effective. Another technology implemented into the WiFi 6 standard is MU-MIMO, or Multi-User, Multiple-Input, Multiple-Output.
With older forms of WiFi, the router would have to take turns communicating with each wireless device. With WiFi 6 and MU-MIMO, the router can communicate with many devices at once. Additionally, OFDMA, or Orthogonal Frequency Division Multiple Access, allow the router to divide the data channel into smaller channels.
These smaller channels allow the router to communicate with multiple devices at once, as well. Latency is the time it takes for data to travel from one device to another on a network. Low latency is important for tasks such as online gaming or video conferencing.
WiFi 6 was designed to reduce the amount of latency that exists in a network. For instance, for online gaming, low latency ensure that the game reacts to the inputs of the player. High latency could result in the game not responding as quick as it should, making it more difficult for the player to win the game.
The placement of the router into a home can impact the performance of the network. The location of the router can impact how well the signal reach each device in the home. Due to the high frequency of the 5 GHz and 6 GHz bands, the signal from the router will not easily pass through walls.
Therefore, you should place the router in a central location within the home and in an area that is open to the remainder of the devices that will connect to the network. Placing the router within a cabinet, for instance, will block the signal from the devices, slowing the speeds at which each device can connect to the network. Various task require different amount of bandwidth from a network.
Bandwidth is the amount of data that pass through a network connection in a given time period. For example, browsing the internet requires less bandwidth than streaming video content at a high rate. The same can be said of online gaming; it does not require much bandwidth, but it does require low latency.
Because WiFi 6 can manage various types of data within the network at once, a person can be streaming video content while another person is online gaming. When purchasing a router that utilize the WiFi 6 standard, you should consider the size of the space and the number of devices that will connect to the network. In small homes with few device, a single dual band router may be all that is required.
In homes with many devices and rooms, however, a mesh WiFi 6 system may be better. A mesh WiFi 6 system sets up multiple node in a structure to allow the signal to spread throughout that space, ensuring that each device in each location receive a strong signal. Finally, each of the devices that will connect to the WiFi 6 network should be compatible with WiFi 6, as well.
