The Wi-Fi market saw a large number of announcements during CES 2021, particularly in routers, chipsets, adapters, and smartphones. A number of companies announced Wi-Fi 6 and Wi-Fi 6E solutions, expanding their offerings into the new protocols to provide the highest quality Wi-Fi connectivity currently possible. Wi-Fi 6, which is now becoming mainstream, provides higher speed connectivity than previous iterations, and also offers upgrades in terms of coverage, power consumption, and scalability. Other features include Orthogonal Frequency-Division Multiple Access (OFDMA), which segments bandwidth into smaller sub-channels to allow more devices to communicate simultaneously; Target Wake Time (TWT), which communicates the optimal wake time for data transmission between devices and access points to reduce power consumption; Basic Service Set (BSS) coloring, which colorizes data from individual access points to provide device identification and support larger numbers of devices; and 8x8 MU-MIMO, which allows access points to support more devices simultaneously. These new products are helping to accelerate growth, and ABI Research expects that over 838 million Wi-Fi 6 chipsets will ship in 2021.
