GPS is the ideal technology to provide global traceability and management of field equipment. It can be deployed quickly and provides worldwide coverage without the cost burden of installing infrastructure like readers. The primary disadvantage, where applicable to the use case, is that GPS requires a view of the sky making indoor tracking (such as inside warehouses) problematic.
RFID is relatively small and low cost, and can track assets while inside or under cover. One downfall is that it typically requires tracking infrastructure (such as gates and readers) to be installed, making RFID impractical in non-fenced areas, like many land rigs. RFID installations typically take more time to implement than stand-alone GPS tracking, and can be very expensive to deploy. The technology is only usable if you know where an asset is going, which is not the case in many field operations.
Since Transem doesn’t offer its own RFID & GPS solutions, we regularly work hand-in-hand with partner companies, knowing that in many cases the combination of both is better than the sum of two separate parts.
