                            NB-IoT (Cat-NB1/NB2): B1, B2, B3, B4, B5, B8, B12, B13, B17, B19, B20, B25, B26, B28, B66
    SIM Size & Access:      Internal Nano 4FF SIM
User-Replaceable Batteries: 3 x AA. Batteries not included.
Supported Battery Types:    Lithium (LiFeS2) or Lithium Thionyl Chloride (LTC) (Please dispose of Lithium batteries in a safe and responsible manner)
*Battery Life Estimates:    Once Daily location updates – 10+ years
                            Movement-Based location updates – 6+ years
                            Hourly location updates – 3.5+ years

*Battery life estimates are influenced by several factors including temperature, installation and orientation of the device, the frequency of location updates, network coverage, sensor integrations, peripherals, accelerometer settings, and more. Battery life calculators are available at
GNSS Module:    Sony CXD5605
Constellation:  Concurrent GPS, GLONASS, Galileo, QZSS
Tracking Sensitivity:   -147 dBm cold start / -161 dBm hot start
*Location Accuracy:     ~1m 2D RMS, GPS, -130dBm
GNSS Assistance:        GNSS almanac and ephemeris data for greater sensitivity and position accuracy
Low Noise Amplifier:    GPS signals are filtered and boosted by a SAW filter and low-noise amplifier (LNA) allowing operation where other units fail
Cell Tower Location:    Cell tower location fallback for positioning when GPS can’t get a fix

*Positioning accuracy specifications are provided by the GNSS supplier and reflect ideal conditions. Device configuration, installation, environmental conditions, augmentation services, and many other factors may lead to variations in positioning accuracy.
