CalAmp ATU-1650MB — Compact Multi-Purpose LTE Cat-M1 Battery-Powered Asset Tracker
The CalAmp ATU-1650MB is a compact, weatherproof, battery-powered GPS asset tracker designed for advanced asset protection, vehicle recovery, equipment monitoring, trailer tracking, and enterprise IoT applications. Combining LTE Cat-M1 cellular connectivity, multi-constellation GNSS positioning, Bluetooth Low Energy 5.2, a high-capacity 4400 mAh LiMnO₂ battery pack, programmable edge intelligence, onboard geofencing, and IP66/IP67 environmental protection, the ATU-1650MB provides long-term location visibility without requiring a connection to vehicle or equipment power. (CalAmp)
Designed for both standalone and dual-device operation, the ATU-1650MB can operate as an independent tracking device or supplement an existing asset-protection system. Its compact and discreet form factor allows flexible mounting across vehicles, trailers, equipment and other high-value assets where conventional hardwired telematics equipment may be impractical. CalAmp specifies battery life of up to seven years under its one-report-per-day operating profile. (CalAmp)
Advanced Multi-Constellation GNSS Asset Location
The ATU-1650MB incorporates a multi-constellation GNSS receiver supporting GPS, GLONASS, BeiDou and Galileo satellite navigation systems. This multi-network architecture provides the positioning foundation required for vehicle recovery, equipment location, asset monitoring and other location-based applications. (CalAmp)
CalAmp specifies less than 2.5-meter CEP location accuracy, with GNSS tracking sensitivity of -161 dBm and cold-start acquisition sensitivity of -145 dBm. The device also supports Assisted GPS (AGPS) location assistance. (CalAmp)
These positioning capabilities make the ATU-1650MB particularly well suited to applications requiring asset location, movement monitoring, recovery assistance, geofencing and historical location reporting without the installation requirements associated with a permanently powered telematics device.
LTE Cat-M1 Cellular Connectivity
The ATU-1650MB provides broad LTE Cat-M1 cellular connectivity across bands B1, B2, B3, B4, B5, B8, B12, B13, B18, B19, B20, B25, B26, B27, B28, B66 and B85. CalAmp also specifies 2G connectivity at 850/900/1800/1900 MHz, supporting additional network compatibility where applicable. (CalAmp)
The tracker uses an internal 4FF SIM, while the cellular antenna is completely integrated within the enclosure. The GNSS and BLE antennas are also internal, allowing the ATU-1650MB to operate without externally mounted antenna assemblies. (CalAmp)
This integrated wireless architecture is particularly valuable for asset-tracking deployments because it minimizes external components and helps maintain the device's compact, self-contained installation design.
Up to Seven Years of Battery Life
One of the defining characteristics of the ATU-1650MB is its 4400 mAh lithium manganese dioxide (LiMnO₂) battery pack. The high-capacity primary battery allows the tracker to operate independently of an asset's electrical system and makes it particularly suitable for equipment, trailers and other assets where permanent power may be unavailable or undesirable. (CalAmp)
CalAmp specifies approximate battery life of:
-
One report per day — up to 7 years
-
Four reports per day — up to 1.5 years
-
One report every 5 minutes — up to 10 days (CalAmp)
Actual battery life varies according to environmental conditions, device installation orientation, reporting frequency, cellular-network availability, advanced configuration settings and use of optional BLE-enabled features. These factors should therefore be considered when designing a reporting strategy for a specific deployment. (CalAmp)
The configurable reporting architecture allows system designers to balance location-reporting frequency against battery longevity, making the ATU-1650MB suitable for both long-duration asset monitoring and applications requiring more frequent position information.
Standalone & Dual-Device Operation
The ATU-1650MB supports both standalone and dual-device operating modes. (CalAmp)
In a standalone deployment, the ATU-1650MB can function as the primary battery-powered location device for an asset. This architecture is useful for assets without accessible electrical power or applications where a self-contained tracking solution is preferred.
CalAmp also positions the device for use as a supplement to existing asset-protection systems. This provides additional deployment flexibility for organizations building layered asset-monitoring or vehicle-recovery solutions. (CalAmp)
Bluetooth Low Energy 5.2
Integrated Bluetooth Low Energy 5.2 provides the ATU-1650MB with a modern short-range wireless interface for supported BLE-enabled functionality and compatible peripheral applications. (CalAmp)
The BLE antenna is completely internal, maintaining the tracker's self-contained physical design without requiring an external antenna or cable.
BLE capability expands the ATU-1650MB beyond basic cellular GPS tracking by providing an additional wireless interface that can be incorporated into compatible asset-monitoring architectures. CalAmp notes that optional BLE-enabled functionality can affect battery life, so BLE usage should be considered when determining the appropriate power and reporting profile for a deployment. (CalAmp)
PEG2™ Programmable Edge Intelligence
The ATU-1650MB incorporates CalAmp's PEG2 programmable device behavior logic, allowing intelligent event processing to occur locally on the tracking device. The underlying software architecture uses ThreadX RTOS together with CalAmp EdgeCore firmware. (CalAmp)
Edge processing allows supported device behavior to be controlled locally rather than requiring every decision to be made by a remote cloud platform. This architecture can be especially important for battery-powered tracking applications because reporting behavior can be optimized around meaningful events and operating conditions.
Programmable edge intelligence can therefore help organizations develop tracking strategies that balance asset visibility, event responsiveness, cellular utilization and battery life.
Onboard Geofencing
The ATU-1650MB supports locally stored geofence data for real-time geospatial processing. (CalAmp)
Onboard geofencing allows geographic rules to be processed by the tracking device itself. This capability can support asset-management applications involving equipment yards, customer sites, storage facilities, restricted areas and other defined geographic zones.
Potential applications include detecting when an asset enters or leaves a designated location, identifying unexpected movement from an assigned area, and incorporating geographic conditions into a broader asset-protection strategy.
20,000-Message Onboard Buffer
The ATU-1650MB can buffer as many as 20,000 messages internally. (CalAmp)
Onboard buffering is particularly valuable for mobile and remote assets because cellular connectivity cannot always be guaranteed. If an asset moves through an area with limited network coverage, supported information can be retained by the tracker rather than relying exclusively on continuous connectivity.
Once appropriate network connectivity becomes available, buffered telematics information can support a more complete operational history.
Rugged IP66 & IP67 Weatherproof Enclosure
The ATU-1650MB is specifically engineered for rugged asset-tracking applications and carries both IP66 and IP67 ingress-protection ratings. (CalAmp)
This weather-resistant construction differentiates the ATU-1650MB from conventional in-cab telematics devices and allows it to address installations where the tracker may encounter dust, moisture and challenging environmental conditions.
CalAmp specifies an operating-temperature range of -25°C to +68°C (-13°F to +154°F). Shock and vibration performance is specified to SAE J1455, while electrostatic-discharge testing is specified to IEC 61000-4-2 at 4 kV. (CalAmp)
These environmental characteristics make the ATU-1650MB appropriate for demanding commercial applications involving trailers, vehicles, industrial equipment and other mobile or stationary assets.
Compact & Discreet Physical Design
Despite incorporating cellular, GNSS and BLE radios together with a substantial 4400 mAh battery, the ATU-1650MB maintains a compact footprint.
The enclosure measures approximately 2.5 × 2.0 × 1.1 inches (63.5 × 50.8 × 27.9 mm) and weighs approximately 3.7 oz (106 g). (CalAmp)
Its compact size makes discreet installation possible in locations where larger battery-powered tracking devices could be difficult to conceal or mount.
CalAmp offers an installation bracket as a separately sold accessory, providing another mounting option for compatible installations. (CalAmp)
Internal USB Configuration Interface
The ATU-1650MB incorporates an internal USB port for debugging and configuration. (CalAmp)
This interface provides technicians and integrators with a local service connection while preserving the sealed external architecture required for rugged asset-tracking applications.
Remote Device Management & OTA Updates
The ATU-1650MB supports CalAmp Device Management, enabling organizations to manage and configure connected assets and deploy over-the-air software updates at scale. (CalAmp)
Remote management is especially valuable for large asset-tracking deployments because physically accessing every tracker for routine configuration or software-management tasks can be costly and operationally impractical.
The ability to remotely manage deployed devices helps support scalable fleet and asset-tracking architectures across geographically distributed equipment.
CalAmp Telematics Cloud Integration
The ATU-1650MB can operate within the broader CalAmp Telematics Cloud ecosystem. CalAmp specifies that telematics information can be streamed into proprietary systems using flexible API integration. (CalAmp)
This allows ATU-1650MB location and device information to become part of larger fleet-management, asset-management, recovery, reporting, analytics and enterprise IoT applications.
For solution providers, API integration also provides a path for incorporating the ATU-1650MB into a proprietary software platform rather than requiring the tracking device to operate as an isolated hardware product.
Regulatory & Carrier Certifications
The ATU-1650MB carries an extensive set of regulatory and industry certifications, including FCC, PTCRB, CE, CE Cybersecurity, ISED, RoHS 3 and E-Mark, along with applicable carrier certifications. (CalAmp)
These certifications, combined with broad LTE Cat-M1 frequency support, position the ATU-1650MB for professional multi-region asset-tracking deployments.
