Detecting presence (arrival/departure) with active RFID tags

up vote 11 down vote accepted

+50

As a top level statement, if you need to track items leaving your site, your RFID technology is probably the wrong one. The technology you have is better suited to the positional tracking tags within a large area - eg a factory floor. Notwithstanding the above, here is my take:

A good approach to active RFID is to break your area down into zones that are tied to...

My experiences with RFID - QtuTrains

Tagging some or all rolling stock is very tempting for many reasons.

As a train passes over a tag reader the controller can:

See the makeup of the train

Know which loco is/are pulling the train.

Know calibration data for how the loco behaves

Deduce the class of the train and how it should be handled.

Know how fast the train should travel.

Calculate the length of the train if all rolling...

Electromagnetic Waves

Michael Faraday proposed in 1846 that both light and radio waves are part of electromagnetic energy.

In 1864 James Clerk Maxwell published his theory on electromagnetic fields and found that electric and magnetic energy propagate in transverse waves at the speed of light

In 1887 Heinrich Rudolf Hertz produced and studied electromagnetic waves. He concluded that...
