Yet Qualcomm was highly enthusiastic about WiFi 6/6E at the time, as were its silicon rivals Broadcom and MediaTek, adding to a sense of crying wolf. These vendors genuinely believed WiFi 6 represented a major step forward in performance, capacity, and robustness. Yet the improvement turned out to be rather underwhelming, certainly until 6E came along,…
