Intelligent Traffic Systems (ITS) rely on high-performance radar sensors to deliver accurate detection in all weather and lighting conditions. But not all radar operates on the same frequency. The two most common in traffic management today are 24 GHz and 77 GHz. At smartmicro, we provide both — because frequency choice depends on deployment goals, site geometry, and regulatory compliance.
24 GHz Traffic Radars: Wide Coverage and Long Range
Our TRUGRD Premium Line operates at 24 GHz, a band authorized in many markets under harmonized SRD (Short Range Device) regulations.
All devices from the TRUGRD Premium Line are radars operating in the 24GHz frequency band. These advanced devices provide accurate vehicle detection, speed measurement, and data collection, contributing to improved road safety and efficient traffic flow. Radars working on the 24GHz frequency, such as TRUGRD radars, can be deployed all over the world, to ensure road safety.
What is a 24GHz frequency radar?
24GHz traffic radars use microwave technology to monitor vehicle movement. They emit microwave signals, which bounce off vehicles and return to the radar, allowing it to calculate speed, direction, and even vehicle classification. The high frequency of 24GHz enables enhanced precision and reliability in various traffic conditions, making these radars an ideal choice for urban environments and highways.
Key advantages of 24GHz frequency in traffic radars
High Accuracy
24GHz radars are known for their precise readings. They are capable of accurate speed detection. This accuracy is crucial for multiple traffic applications like intersection management or highway management.
Weather Resistance
24GHz radars have a high resilience to weather conditions, including rain, fog, and dust. This ensures consistent performance and reliable data collection, even in challenging environments.
Real-Time Data Processing
24GHz radars such as TRUGRD Premium sensors provide real-time data flow. This allows triggering direct feedback to traffic management systems, enabling quick responses to changing traffic conditions and enhancing road safety.
77 GHz Traffic Radars: High Resolution and Compact Design
Our TOPGRD Compact Line uses the 77 GHz band, which is increasingly the global standard for automotive and roadside radars.
TOPGRD and UMRR-11 Type 132 are radars operating in the 77GHz frequency band, offering exceptional accuracy and reliability for various applications, like intersection management and highway monitoring. The 77GHz radar sensors, such as the TOPGRD and UMRR-11 Type 132, are designed to enhance road safety and efficiency in traffic flow management in cities.
What is a 77GHz frequency radar?
77GHz radar technology utilizes electromagnetic waves at a high frequency, providing precise measurements of speed and distance. This technology is particularly favored in traffic management, enforcement, and intelligent transportation systems. The reliable performance of 77GHz radar sensors makes them ideal for integration into various systems, ensuring seamless operation in dynamic environments.
Key advantages of 77GHz frequency in traffic radars
High Resolution
With its fine frequency resolution, 77GHz radar can deliver accurate speed and distance measurements, minimizing the risk of dangerous road situations.
Improved Performance
The 77GHz frequency allows for more precise detection and extended detection range, enabling effective monitoring of fast-moving vehicles and reducing blind spots.
Low Power Consumption
77GHz radar sensors are highly efficient, which leads to lower energy consumption. That is a significant advantage for sustainable traffic management.
Choosing the Right Frequency for Your ITS Project
There is no “better” frequency, only the right fit for your site and goals.
- Select 24 GHz (TRUGRD) when you need wide coverage and long detection distances.
- Choose 77 GHz (TOPGRD) when you need high resolution, VRU protection, or compact hardware.
By offering both 24 GHz and 77 GHz radar sensors, smartmicro enables cities and system integrators to deploy tailored, compliant, and future-proof traffic solutions.
