RFID/GPS/Location Channel

Tracking rail carts: What would it take to increase GPS penetration rates?

Tracking rail carts with GPS and cellular could bring value to the rail sector; however, penetration rates on rail carts are currently very low (globally less than 50,000 in 2014), and growth is not forecasted to be very strong over the next 5 years, or even the next 10, according to ABI Research. Therefore, for the time being at least, it looks like RFID will dominate this sector.
