Abstract
Systems and methods for warning of proximity in a worksite are disclosed. A second transceiver is detected at a first transceiver, wherein the first transceiver is a mobile wearable device, and wherein the first transceiver and the second transceiver are located at a worksite. An ad-hoc network is established, at the first transceiver, between the first transceiver and the second transceiver. A distance is calculated, at the first transceiver, in three dimensions between the first transceiver and the second transceiver based on the detecting the second transceiver. A first safety envelope is defined, at the first transceiver, about the first transceiver and a second safety envelope about the second transceiver. An alarm is issued, at the first transceiver, when the first safety envelope comes in contact with the second safety envelope.
