Vehicle Asset Management System

Vehicle Asset Management System

Plextek are responsible for the design and manufacture of the Redtail Telematics range of Vehicle Asset Management (VAM) products. VAM products enable efficient management of vehicular fleets (e.g. taxi fleets, emergency services and heavy equipment/machinery) and offers driver-behaviour monitoring for the vehicle insurance markets. This is achieved through incorporating cellular modems and GPS modules, both of which require antennas to function effectively.

There is often enormous market pressure to reduce the size of products of this kind, for example, so that it can fit into a cramped location in the vehicle. This can transform the development of the antenna system from a straightforward integration of individual designs, focussed on particular frequency bands, to a highly complex custom development. Each antenna interacts strongly with other antennas and with components of the product (PCB, battery etc). In many ways, it can be said that the entire product becomes the antenna.

Fortunately, we have the ability to model the electromagnetics of the entire product, allowing us to predict the impact of design changes and reduce the need to iterate. The antenna design process used by Plextek also takes account of the VAM product placement in the vehicle, in particular, consideration of materials close to the VAM unit that might affect the performance of the antenna system.

The VAM product uses a custom designed multiband-band cellular antenna, integrated onto a PCB substrate together with a custom GPS antenna. This solution exceeds the performance requirements set out in the standards, resulting in a lower product cost than the equivalent COTS antennas and allows integration into a tiny product package.
