Abstract

Examples are disclosed for wireless communication between a terminal computing device and a wearable computing device. In some examples, wireless local area network (WLAN) transmissions for packets of various sizes may be transmitted from a terminal computing device to a wearable computing device. At least some of the WLAN transmissions may be used by the terminal computing device to communicate to the wearable computing device based on the wearable computing device having an ability to detect the variable packet sizes. Other examples are described and claimed.
