VHF band (30300MHz) data transmission core advantages:
strong diffraction capability, good penetration of buildings/vegetation, transmission distance of 550km (apparent power/antenna), suitable for medium-to-short distance outdoor data communication.
Key Features
Frequency Band Allocation: Commonly used 136174MHz (civilian/industrial), 220230MHz (dedicated), less interference compared to UHF;
Transmission Rate: Standard 1.2-9.6kbps (suitable for sensor data, control commands), high-speed solutions can reach 100kbps+;
Core Advantages: Superior anti-blocking capability compared to UHF, lower power consumption than HF, low deployment cost (no complex antenna required).
Typical Application Scenarios
IoT Monitoring: Outdoor environmental sensor (temperature, humidity, water level) data transmission, remote control of agricultural irrigation;
Industrial Communication: Remote data transmission for oil field/mining equipment, communication for special equipment in ports/docks;
Emergency Communication: Data transmission for fire/rescue on-site command, temporary communication links in remote areas;
Vehicle/Mobile: Fleet dispatch data transmission, short-range near-shore communication for ships.
