FIELD: radio engineering, communication.
SUBSTANCE: invention relates to wireless communication. Described is a mechanism for detecting distance between devices based on Wi-Fi signals. The method includes determining strength of one or more signals being communicated between one or more antennae of a first device and two or more antennae of a second device. The one or more signals are associated with a multicast packet and determining the distance between the first and second devices based on the determined strength of the one or more signals.
EFFECT: high efficiency of detecting distance between computing devices.
