Abstract
Systems and methods for enabling proximity operations with long-range wireless communication interfaces are described. In an illustrative, non-limiting embodiment, a method may include transmitting a plurality of data packets using a WiFi interface of a first device, where each data packet has a signal strength following a predetermined pattern; and receiving an indication, via the WiFi interface, of whether the predetermined pattern has been identified by a second device.
