4G Smart Watch Options
The HW01 is designed for kids GPS watch and smart campus projects. It supports 4G communication, multi-mode positioning, SOS calling, approved contacts, IP68 protection, and optional NFC integration.
The HW04 uses a round display and is intended for student communication and campus safety projects requiring location history, geofence alerts, family calling, and centralized management.
The HW03 combines a touchscreen, 4G communication, positioning, SOS calling, IP68 protection, and activity or sleep-related functions.

Available functions include 4G calling, SOS assistance, location tracking, geofencing, and health-related measurements such as heart rate and blood oxygen. Any fall-detection requirement should be confirmed separately for the selected software and sensor configuration.
Project Requirements
Location update frequency directly affects battery life and data use. Before sample testing, confirm the target country, operator, LTE bands, VoLTE service, SIM and APN settings, required update interval, expected battery performance, waterproof rating, platform architecture, and data storage requirements.
Health-related readings are intended for daily reference and should not be presented as medical diagnosis unless the project has the required medical certification.
Read our GPS Tracker Update Intervals and Battery Life guide for more information about tracking frequency and battery performance.
KAER supports firmware, app and platform adaptation, API integration, private server deployment, LTE band configuration, UI and logo customization, colors, packaging, and OEM/ODM development.
Contact KAER with your target market, operator, required functions, and deployment quantity to discuss your 4G smart watch project.
