Frequency band and regulations
8.1
24 GHz regulations
Infineon’s BGT24LTR11 radar sensor operates in the globally available 24
GHz bands. There is an ISM band from
24 to 24.25 GHz. However, each country may have different regulations in terms of occupied bandwidth,
maximum allowed radiated power, conducted power, spurious emissions, etc. Therefore, it is highly
recommended to check the local regulations before designing an end product.
8.2
Regulations in Europe
In Europe, the European Telecommunications Standards Institute (ETSI) defines the regulations. For more
details on the ETSI standards, please refer to the document
.
Please note that some countries
do not follow harmonized European standards. Thus it is recommended to check national regulations for
operation within specific regions and monitor regulatory changes.
8.3
Regulations in the United States of America
In the USA, the Federal Communications Commission (FCC) defines standards and regulations. The ISM band
covers 24 to 24.25 GHz and one can operate field disturbance sensors anywhere within this band within allowed
power limits for certain applications. For details, please refer to FCC section number
