At its beginning, connecting remote/mobile assets was expensive and largely based on connectivity through satellite-based systems, and as one would expect, with expensive inputs, use cases focused on high value assets where ROI was quick – Omnitracs fleet tracking through satellite and GPS tracking of commercial aircraft, for instance. The advent of digital cellular in the late 1990s allowed wireless air time to become cheaper, enabled lower value use cases like wireless security alarm systems, cellular controlled door locks, and telematics applications for automobiles, all of which have flourished over the past 10 years.
