An increasing number of broadband households are adopting Wi-Fi as an essential part of their home network. As the number of connected devices per household continues to grow, the majority of traffic in a residential broadband network is transferred through Wi-Fi networks. The emergence of internet of things (IoT) further drives the use of Wi-Fi in residential households. The demand for high efficiency Wi-Fi networks that can support multiple devices with better coverage is expected to grow with the adoption of Wi-Fi devices and bandwidth-demanding applications.
