Review of two Cradlepoint mobile routers

At the transportation organization where I work, we employ two Cradlepoint mobile-router models in our vehicles: the industrial IBR-1700 vehicular routers in our 97 buses and eight smaller IBR-900 vehicular routers in maintenance trucks, operations vans, and other multipurpose vans.

The reason for these cellular routers in the buses is to provide a WAN connection to systems on the buses including GPS, electronic signage, passenger counters, and fareboxes.

How they are networked

These information-gathering systems connect to the primary processing device on the vehicles called the medius box, which is part of our computer-aided dispatch/automatic vehicle location (CAD/AVL) setup. The medius boxes are connected to the Cradlepoint routers, which link over 4G LTE to a server that collects and manages all of the vehicle’s location and onboard media data.
