Abstract
A tag detects a condition, and selectively operates a portion of its circuitry in first and second modes as a function of information regarding the selected condition, the portion consuming less power in the second mode than the first mode, and being capable of wireless communication according to one of a cellular telephone network communication protocol, a satellite communication protocol, and a wireless computer network communication protocol. According to a different aspect, a tag carries out geofencing analysis, and selectively operates a portion of its circuitry in first and second modes as a function of results of the geofencing analysis, the portion consuming less power in the second mode than in the first mode, and being capable of wireless communication according to one of a cellular telephone network communication protocol, a satellite communication protocol, and a wireless computer network communication protocol.
