Abstract
A multi function personal alert safety cell system having condition responsive sensors and an alarm for emergency type personal. The personal alert safety cell system having a transceiver. The transceiver for transmitting and receiving at several different radiated power levels, defined as P.sub.1, P.sub.2, P.sub.3, P.sub.4, P.sub.5, through P.sub.n that vary in signal strength from 1 microwatt through 1 watt. Each power level P.sub.1, P.sub.2, P.sub.3, P.sub.4, P.sub.5, through P.sub.n being transmitted and received with encoded data and a personal ID uniquely assigned to the transceiver of the cell system. Also, the transceivers transmitting and receiving data being contained within a time frame and having digital instructions and coded format sectors. The power level ID varying in field strength for defining a distance at which the transceiver detects the transmitted and received signal from another of PASS transceiver and the signal being indicative of the distance the transceiver is from the other PASS transceivers.
