Wi-Fi 6 - the next generation wireless and four reasons why it matters!

 

The demand for wireless access has shifted to a necessity. Both consumers and business users expect a fast and reliable Wi-Fi connection. There is a proliferation of connected devices, or even machines transferring data over a network. So, the challenge becomes how to deliver a quality network experience with high availability and speed and with a secure connection.

 

Wi-Fi 6 is the new standard that will enhance the efficiency of wireless in high-density environments. A high-density environment does not necessarily equate to a large number of clients, but it can refer to devices and applications running on the network. Wi-Fi 6 is expected to hit the market in 2019. 

 

According to the Wi-Fi Alliance, Wi-Fi CERTIFIED 6™, the industry certification program based on the IEEE 802.11ax standard, enables next generation Wi-Fi connectivity providing the capacity, coverage, and performance required by users—even in environments with many connected devices such as stadiums and other public venues. “  Wi-Fi CERTIFIED 6™ networks enable lower battery consumption in devices, making it a solid choice for any environment, including smart home and Internet of Things (IoT) uses.”

 

Why a new standard and the four reasons why you need it

 

Let’s look at some of the features of Wi-Fi 6 and why you might need it:

 

  1. Increased Capacity: 802.11ax is the next IEEE standard. The benefit of this new standard is that it increases capacity by up to 4x and improves spectral efficiency to benefit both 2.4 GHz and 5 GHz bands in a variety of environments.
  2. Multi-Users Feature: The most important new feature in the Wi-Fi 6 standard is an enhanced multi-user feature called OFDMA (Orthogonal Frequency Division Multiple Access). Multiple devices with varying bandwidth needs can be served simultaneously instead of the existing model where devices compete with one another to send data.
  3. Multi User MIMO  (multiple-input and multiple-output) is another way to handle traffic from multiple devices. Within WiFi 6, this feature has been enhanced by allowing up to eight devices to transmit simultaneously using a dedicated channel per device.
  4. Better Battery: Wi-Fi 6 enables lower battery consumption in devices—so more battery life, and better for energy output and the environment.

 

In summary, the efficiency improvements in Wi-Fi 6 amount to a faster performing network and enhanced user experience for all the clients on the network including mission critical business applications requiring high bandwidth and low latency.
