Asset tracking deployments fail more often from hardware selection errors than from platform configuration issues. The most common mismatch is choosing an unpowered gateway when the operation needs frequent updates, or choosing a powered gateway where running the required cable is impractical. The current AG51 Unpowered Asset Gateway and AG53 Powered Asset Gateway serve different use cases, and understanding when each one wins prevents expensive rework and missed location data during the first months of operation.
Non-powered trackers: the right fit
The Samsara AG51 is designed for mobile assets that do not have a reliable power source and where running a cable is impractical. Classic use cases include intermodal containers, construction equipment, dumpsters, and light towers. Samsara specifies a typical battery life of 3–5 years using three user-replaceable AA lithium batteries at two check-ins per day.
Battery life changes with reporting frequency and operating conditions. More frequent check-ins consume more power, while extreme temperatures and poor cellular signal can also shorten service life. Vidmatics configures the reporting schedule during deployment setup around the visibility the operation actually needs instead of applying a vehicle-tracking cadence to every unpowered asset.
Powered trackers: when to invest in the cable run
The AG53 Powered Asset Gateway is designed for powered equipment and trailers, including dry vans, chassis, flatbeds, reefers, tankers, generators, and compressors. It supports multiple power and cable options, allowing the installation to be matched to the asset and the operational data the fleet needs.
A powered installation requires more planning than mounting an AG51 because the technician must identify a compatible power source, cable, and mounting location. That investment makes sense when the operation needs frequent location updates or asset-specific inputs. Where power access requires extensive disassembly—or no dependable source exists—the AG51 is usually the more practical choice.
Making the call on mixed asset pools
Most fleets that track assets have both powered and unpowered candidates in the same operation. Start with three questions: does the asset have a dependable power source, how frequently must its location update, and does the installation need asset-specific inputs or accessories? Use the AG53 when available power and operational requirements justify a wired gateway; use the AG51 when long-term, scheduled location reporting without asset power is the better fit. Use the smaller AT12 Asset Tag for tools, attachments, and other mission-critical items that are better located through the Samsara Network than through a cellular gateway of their own.
If you are planning an asset tracking deployment and are unsure how to classify your inventory, Vidmatics conducts an asset audit as part of the pre-deployment process. The audit matches the AG51, AG53, or AT12 to each asset category, sets an appropriate reporting schedule, and confirms cable and mounting requirements before hardware is ordered.
