More Devices. Faster Speeds. How to Get There with OFDMA and 802.11ax.

Video doorbells. Virtual reality headsets. Smart washing machines. With a growing number of connected devices in the home, we’ll need faster, smarter, and more responsive Wi-Fi so that everything can connect smoothly. As we’ve discussed before, 802.11ax will play a big role in delivering incredible connected experiences by shifting the responsibility of managing airtime utilization to the home router or gateway. However, the key is to use the full set of 802.11ax features to meet the required Wi-Fi performance metrics.

802.11ax OFDMA

Orthogonal frequency-division multiple access (OFDMA) is one of those key features that can help improve connection density, spectrum efficiency, latency and area traffic capacity. It lets you split bandwidth into more resource units, allowing more user data and types of traffic to be transmitted between clients and the router at the same time. This dramatically improves how efficiently the wireless spectrum is used, resulting in faster uploads and downloads and improved responsiveness—and a much better user experience.

To get the most from OFDMA and the other new features available with 802.11ax, you’ll want to take into account the scheduling capabilities of a technology vendor’s Wi-Fi chipsets.

For our part, Intel will offer 802.11ax chipsets for both clients and home infrastructure that are designed to maximize performance through robust scheduling. You can learn more at
