GV75LAU-LTE Cat 4/3G/2G rechargeable waterproof tracking devlce supporting BLE 5.2
The device is a LTE Cat 4/3G/2G rechargeable waterproof tracking device supporting BLE 5.2, with dimensions of 95(L) × 52(W) × 18.3(H) mm and a weight of 141.5 g. It operates on a voltage range of 9 - 90V DC and features zero power consumption to prevent vehicle battery drain when ignition is off. It is IP67 waterproof and operates within a temperature range of -30℃ to +70℃, with storage temperatures from -40℃ to +80℃.
The device includes a micro USB interface for configuration, upgrade, and debugging, a serial port for external devices, and internal antennas for cellular, GNSS, and BLE. It also features LED indicators for CEL, GNSS, and PWR.
Operating on LTE-FDD bands B1/B2/B3/B4/B5/B7/B8/B28 and LTE-TDD band B40, it supports data transmission rates of up to 150Mbps (DL) and 50Mbps (UL) for LTE-FDD, and 150Mbps (DL) and 30Mbps (UL) for LTE-TDD.
The device operates on bands B1/B2/B5/B8, with data transmission capabilities of DC-HSDPA at 21Mbps (DL) and HSUPA at 5.76Mbps (UL). WCDMA supports up to 384Kbps for both DL and UL.
Frequency bands include EGPRS: 850/900/1800/1900MHz, with EDGE data transmission rates of 236.8Kbps for both DL and UL, and GPRS rates of 85.6Kbps for both DL and UL.
The device uses a u-blox All-in-One GNSS receiver with a position accuracy of less than 2.0m CEP. Cold start sensitivity is -148 dBm, hot start is -160 dBm, and tracking is -167 dBm. TTFF averages 24s for cold start and 1s for hot start.
Supports transmit protocols TCP, UDP, and SMS, with scheduled reporting based on time intervals, distance, or mileage. It supports up to 20 geo-fence regions and includes alarms for low power, power on, towing, jamming detection, and special alarms based on digital/analog inputs.
Features include detection of aggressive driving behaviors such as harsh braking and acceleration, as well as crash detection for accident data collection and analysis.
The device supports OTA control of digital outputs, with configurable digital output/input, a digital output with internal latch circuit, and a positive trigger input for ignition detection.
Data is reported to the MQTT server with TLS 1.2 encryption for secure transmission.
