Typical differences between 5.8GHz and 10.525GHz microwave radars

2022-11-03

As one of the core technologies of the sensing layer of the Internet of Things, microwave radar technology is facing great application opportunities in product lines of various industries, endowing intelligent sensing functions to related product lines, and greatly promoting the construction of AIoT system. But there are many kinds of microwave radar frequency band classification. What are the main differences between different frequency bands?

Today first to talk about the difference between 5.8GHz and 10.525GHz, 5.8GHz belongs to the C-band (4~8GHz), the corresponding wavelength of 5.2cm, 10.525GHz belongs to the X-band (8~12GHz), the wavelength is 2.8cm. In practical applications, the product lines of 5.8GHz and 10.525GHz applications are overlapped in most scenarios, that is, the "intersection" is very large, and there are only subtle differences in a few scenarios (that is, there are "difference sets").

5.8GHz and 10.525GHz radar have the same performance, such as all-weather, all-day, not affected by ambient temperature, dust, haze, light, etc., can adapt to complex climate conditions, non-contact sensing, can largely replace the traditional infrared sensor. Therefore, the two frequency bands can be applied to many product lines such as lighting, household, security, AIoT, etc., and the product lines of both bands can be applied to a wide range.

In the application of specific scenario product line, the performance of 5.8GHz radar is better than 10.525GHz in the application of terminal products such as long-range and high-altitude (such as 10m-12m) due to the frequency band wavelength characteristics. In ultra-close range (such as 10cm-30cm), large-scale centralized applications or networking, alarm detection and other product applications, 10.525GHz is more advantageous than 5.8GHz.
