Things You Should Know About Wi-Fi 6 Before It Becomes Popular

802.11ax is the new Wi-Fi standard, popularly known as Wi-Fi 6. With this, you will experience better speed, more efficiency, greater usability, and extended battery life. In this article at the SHI Blog, LinWood Walker discusses pointers you should know about Wi-Fi 6 before it becomes popular.

Understanding the New Wi-Fi 6

Wi-Fi 6 is a new Wi-Fi standard that will make IoT devices easier to implement. While the previous standards allowed one, the new Wi-Fi will allow nine data streams to work on the same frequency. Four upstream, four downstream, and one management channel can easily transmit. The standard has been introduced in 2018 and manufacturers are already working on its use cases. Some have released APs and integrated them in new smartphones, laptops, and IoT devices.

Benefits:

  • 64 billion IoT devices will be in use by 2025, six times that of 2018. Wi-F 6 will allow consistent connectivity in such a dense environment.
  • The new standard uses multiple-user multiple input multiple output (MU-MIMO). Wi-Fi 5 first had this feature that allows each access point (AP) to transmit data to up to 8 devices simultaneously. Wi-Fi 6 is using Orthogonal Frequency Division Multiple Access (OFDMA) ‘to split each MU-MIMO stream into four more streams’.
  • Previously, a device would continuously interact when present in an AP’s roaming area. The new standard used Target Wake Time to connect devices on a specific time while allowing them to hibernate otherwise. This will save a lot of battery life for both smart and IoT devices.

Roadblocks:

  • Wi-Fi 6 requires new hardware, cables, and LAN. Schools and organizations that run in existing equipment cannot switch to Wi-Fi 6 soon.
  • Budget can be the biggest roadblocks for all. Some of the organizations are still shifting from Wi-Fi 4 to 5. Some are happy with the way things are now and do not want to disrupt for an untested standard. Meanwhile, others feel that networking and IT are not a part of their core business processes.
