# Device

A wireless client refers to any device that connects to a network using WiFi technology.  For optimal performance with WiFi Sensing, stationary devices such as voice assistants (like Amazon Echo or Google Nest), smart plugs, smart displays, and powered wireless speakers are ideal choices.  Wireless clients that are mobile can move around and generally have aggressive sleep modes, less reliable Channel State Information (CSI) data, and are not able to be used to help identify localization, all of which can impact the WiFi Motion performance.
