About Wilus Portfolio

The 802.11ax (“Wi-Fi 6”) Standard was published in May 2021. This latest generation of Wi-Fi was designed to address the problem of low efficiency resulting from the massive increase in the number of devices accessing the Internet over the past decade.

Wi-Fi 6 addresses this problem by increasing the average throughput per user by four and the number of concurrent users by more than three in high density scenarios (e.g., offices, campuses, airports, stadiums, etc.) when compared to Wi-Fi 5. It also provides other improvements, such as: extended wireless range, longer battery life and coexistence with legacy Wi-Fi devices.

Such significant technical improvements are enabled through the addition of more than 40 core features. The innovations covered by the Wilus’ Portfolio contribute to about 90% of them.

The improvement evolution of certain technical features from Wi-Fi 4 to Wi-Fi 6, that makes this accommodation of modern-day wireless connectivity possible, is illustrated below.
