Wi-Fi played a critical role in providing digital infrastructure to support increased connectivity demands during the global pandemic. With greater worldwide availability of 6 GHz, wider adoption of WPA3 security, and global momentum of Wi-Fi 6 across more enterprise and vertical markets expected in the coming year, Wi-Fi is ready to deliver innovation and advanced connectivity when and where users need it most.
As the world reflects on a challenging 2020, Wi-Fi Alliance® looks ahead at five Wi-Fi predictions for 2021 that will help people safely resume their normal activities, achieve better performance in their home networks, and deliver greater reliability and latency for telehealth, virtual learning, and telepresence.
Wi-Fi Alliance predictions for Wi-Fi in 2021 include:
1. Wi-Fi 6 global momentum
Wi-Fi 6 is the latest generation of Wi-Fi offering greater capacity, efficiency, and performance for advanced connectivity. Wi-Fi 6 will see strong global adoption across PCs, access points, smartphones, and IoT devices in enterprises, homes, and public arenas – with nearly 2 billion Wi-Fi 6 device shipments expected in 2021. The pandemic has proven a strong need for state-of-the-art networks to support more online activity. Wi-Fi 6 networks will become more widely deployed in the home and see steady rollout in the enterprise to ensure all networked devices perform at an optimal level and support environments with greater capacity and coverage.
2. Wi-Fi 6E will deliver 6 GHz to users
Regulatory momentum around 6 GHz will lead to greater availability of unlicensed spectrum for Wi-Fi worldwide in 2021. The U.S. recently cleared unlicensed access to 1200 MHz of spectrum in the 6 GHz band. The U.K., Europe, South Korea, Chile, Brazil, and the United Arab Emirates are expected to deliver 6 GHz to their citizens before the end of the year, and many other countries are following their lead. Users will see worldwide rollout of Wi-Fi 6E devices as multiple vendors embrace 6 GHz. Up to seven superwide 160 MHz channels can be used with this newly available spectrum, triggering development and innovation for higher bandwidth applications including unified communications, AR/VR, and even holographic video.

3. Passpoint® bridges the gap between Wi-Fi and cellular
Solutions such as Wi-Fi CERTIFIED Passpoint® will help bridge the gap between cellular and Wi-Fi to make Wi-Fi more accessible and secure. Passpoint streamlines Wi-Fi access and eliminates the need to reauthenticate to networks previously visited, enabling users to focus on productivity without manually switching their device between cellular and Wi-Fi to determine the best connection.
4. Strong adoption of WPA3 security
The latest generation of Wi-Fi security, WPA3, brings critical updates to personal and enterprise networks to protect users wherever they connect. Wi-Fi Alliance now requires all new Wi-Fi CERTIFIED devices to support WPA3 security, and in 2021 the industry will see greater adoption of WPA3 across more devices, networks, and environments – including sensitive environments like governments and financial institutions. The number of devices connected to the internet, including machines, sensors, and smart home devices is forecast to reach 41.6 billion in the next four years1. With that tremendous growth comes demand for strong security mechanisms to protect the increasing amount of user data generated by IoT devices.
