Since only one wireless device can transmit at once, wireless transmissions are doubled (router to the repeater and then repeater to the client versus just router to the client), and so: Wireless throughput is reduced by at least 50%. [1] Wireless interference (e.g., with other networks on the same channel) is at least doubled.
Long-range Wi-Fi is used for low-cost, unregulated point-to-point computer network connections, as an alternative to other fixed wireless, cellular networks or satellite Internet access. Wi-Fi networks have a range that's limited by the frequency, transmission power, antenna type, the location they're used in, and the environment. [ 1 ]

Smart home devices such as Google Wi-Fi, Google Nest Wi-Fi, and Google OnHub support Wi-Fi mesh (i.e., Wi-Fi ad hoc) networking. [10] Several manufacturers of Wi-Fi routers began offering mesh routers for home use in the mid-2010s. [11] Some communications satellite constellations operate as a mesh network, with wireless links between adjacent ...
A wireless network interface controller (WNIC) is a network interface controller which connects to a wireless network, such as Wi-Fi, Bluetooth, or LTE (4G) or 5G rather than a wired network, such as an Ethernet network. A WNIC, just like other NICs, works on the layers 1 and 2 of the OSI model and uses an antenna to communicate via radio waves
