1. Product Overview

The M38 GPS Tracker is an ultra-compact, high-performance tracking device designed for real-time positioning and monitoring. With triple-mode satellite support (GPS+Beidou+GLONASS) and 4G Cat1 connectivity, it ensures accurate and reliable tracking for vehicles, assets, or personal use. Its plug-and-play design, built-in backup battery, and magnetic charging make it easy to install and maintain.

Since it has voice functionality, this product is only sold in countries where it is legally permitted. It does not support unauthorized surveillance or recording, and all voice features are strictly designed for legitimate purposes such as emergency communications and authorized location tracking.

5. What is 4G Cat1?

4G Cat1 (short for 4G Category 1) is a classification standard for terminal devices in 4G LTE networks, designed as a low-power, low-cost, medium-to-low-speed communication solution for the Internet of Things (IoT). Below is a detailed breakdown:

(1). Basic Definition

4G Cat1 is one of the 4G LTE terminal categories defined by 3GPP (the international telecom standards body), optimized for IoT devices. It offers moderate upload/download speeds while meeting most IoT application requirements.

Key Features:

• Speed: Downlink 10Mbps / Uplink 5Mbps (theoretical).
• Power Efficiency: Lower consumption than traditional 4G Cat4, ideal for battery-powered devices (e.g., our GPS tracker).
• Cost: Modules are inexpensive with simple hardware design.

(2). Comparison with Other 4G Categories

(3). Why Youwei GPS Tracker Uses 4G Cat1

• Battery Savings: Fits long-term standby tracking.
• Adequate Performance: GPS data requires minimal bandwidth (no need for high-speed video streaming).
• Wide Coverage: Compatible with existing 4G base stations, no extra infrastructure needed.
