Wireless devices, systems and methods for object tracking

A tracking system comprising:

• a central processing unit;
• a device comprising a processor, an antenna and a device identifier;
• a first wireless transmitter configured to be in wireless signal communication with the central processing unit;
• and
• a plurality of second wireless transmitters configured to be in wireless signal communication with one another through at least a communication chain, wherein at least one of the plurality of second wireless transmitters is further configured to be in wireless signal communication with the central processing unit, the tracking system configured to provide tracking information through wireless signal communication between (i) the device and, over a Bluetooth® Low Energy wireless communication technology, the first wireless transmitter or at least one of the plurality of second wireless transmitters when the device is within wireless signal communication range therewith, (ii) the device and, over at least one of a plurality of other wireless communication technologies, at least one of:
• the first wireless transmitter when the device is not within wireless signal communication range of the first wireless transmitter over the Bluetooth® Low Energy wireless communication technology;
• at least one of the plurality of second wireless transmitters when the device is not within wireless signal communication range of any of the plurality of second wireless transmitters over the Bluetooth® Low Energy wireless communication technology;
• or
• the central processing unit when the device is not within wireless signal communication range of the first wireless transmitter the over the Bluetooth® Low Energy wireless communication technology or any of the plurality of second wireless transmitters over the Bluetooth® Low Energy wireless communication technology.
