Methods and system for reduced attenuation in tracking objects using RF technology

A system for RF-based tracking and locating objects, comprising:

• a plurality of Master Units each having an RF transceiver and each adapted to interface to a Tag to measure distances to the Tag from each Master Unit of the plurality of the Master Units;
• and
• the Tag having an RF transceiver and adopted to interface to the plurality of the Master Units,
• wherein the RF transceivers of the Master Units and the RF transceiver of the Tag are configured to transmit and receive a narrow bandwidth ranging signal in no higher than a VHF band,
• wherein the narrow bandwidth ranging signal includes multiple pulses at different frequencies, and
• wherein the narrow bandwidth ranging signal is used for measuring the distance between the Master Units and the Tag.

A method for RF-based tracking and locating objects, comprising:

• transmitting, by a Master Unit, and receiving, by a Tag, a narrow bandwidth signal;
• the Master Unit having an RF transceiver adapted to interface to the Tag and
• the Tag having an RF transceiver adopted to interface to the Master Unit;
• and
• wherein the RF transceiver of the Master Unit and the RF transceiver of the Tag are transmitting and receiving the narrow bandwidth ranging signal in no higher that a VHF bands to measure a distance between the Master Unit and the Tag, and
• wherein the narrow bandwidth ranging signal includes multiple pulses at different frequencies.
