The 4G + GNSS combination antenna is a multi-band radio frequency device that integrates mobile communications (4G/LTE) and global navigation satellite system (GNSS) signal reception functions. It is specifically designed for scenarios that require simultaneous data transmission and high-precision positioning.

Frequency band coverage：

• 4G frequency band: Supports 700-960MHz (low frequency, wide coverage) and 1710-2690MHz (mid-high frequency, high-speed transmission)

• GNSS frequency band: Covers 1565-1606MHz (compatible with the L1 frequency band of satellite systems such as GPS, Beidou, and GLONASS)

Technical advantages：

• Multi-link coordination: Supports 4G+GNSS dual mode or can be expanded to 4G+Wi-Fi+GNSS triple mode, reducing the number of external antennas required for the device

• High integration: Through PCB layout optimisation (such as GNSS ceramic chip and 5G-MIMO partitioning), the volume is reduced by over 30%

• Wide temperature adaptability: Operating temperature range from -40°C to 85°C, suitable for harsh outdoor and vehicle environments

Typical Application Scenarios：

• Intelligent Transportation

Vehicle-mounted T-BOX: Enables real-time vehicle positioning (centimetre-level accuracy) and 4G remote communication

Fleet management: Combined with V2X antennas, supports trajectory tracking and high-definition video transmission

• Industrial Internet of Things

Engineering monitoring: Field deformation observation equipment integrates GNSS positioning and 4G data reporting

Power Grid Equipment: Dual-frequency GNSS modules ensure synchronised tower coordinates and status monitoring

• Smart Cities:

Public Facility Monitoring: Covertly installed in streetlights and traffic signal poles, supporting remote management
