The EN 300 328 standard is one essential technical regulations for wireless products, which establishes electromagnetic compatibility (EMC) and radio spectrum requirements for radio equipment. Its application is crucial to ensure the correct functioning of wireless devices and to prevent interference with other electronic equipment present in the same environment. In this article, we will explore the details of the EN 300 328 standard and the importance of its certification for wireless device manufacturers.
The EN 300 328 standard
The EN 300 328 standard, issued by the European Committee for Standardization (CEN), applies to all devices that they operate in the spectrum from 9 kHz to 300 GHz. The standard defines the technical requirements that products must satisfy to guarantee electromagnetic compatibility, protection from disturbances and the effective use of the radio spectrum. It covers a wide range of wireless devices, including Wi-Fi routers, Bluetooth devices, IoT devices, wireless communication systems, telemetry equipment, and many others.
Requirements of the EN 300 328 standard
The EN 300 328 standard establishes specific requirements for various characteristics of wireless devices, including transmission power, bandwidth, spectral efficiency, reception sensitivity and interference protection. The standard also defines the compliance tests that manufacturers must perform for demonstrate that their products meet these requirements. Compliance testing evaluates electromagnetic compliance, radio spectrum compliance, and interoperability of devices.
Product certification
To market and distribute wireless devices on the European market, manufacturers must obtain EN 300 328 certification. The certification confirms that the products comply with the requirements of the standard and that they have undergone the appropriate conformity tests. Certification can be obtained through accredited certification bodies, who evaluate the test results and issue the certificate of conformity. The presence of the EN 300 328 conformity mark on the product guarantees end users that the device has been adequately tested and that it complies with quality and safety standards.
Benefits of certification
The EN 300 328 certification offers numerous benefits for both manufacturers and end users of wireless devices. For manufacturers, the certification demonstrates commitment to quality and compliance with European standards, increasing customer confidence and facilitating access to the European market. In addition, the certification helps to reduce the risk of interference with other electronic equipment, ensuring the interoperability of wireless devices. For end users, certification offers the guarantee of reliable, safe products that comply with quality standards.
Conclusions
The EN 300 328 standard is fundamental for wireless products and for ensure electromagnetic compatibility, noise protection and interoperability. The EN 300 328 certification confirms that the products meet the requirements of the standard and that they have undergone the appropriate conformity tests. It delivers advantages for both producers and end users, helping to ensure wireless products are safe, reliable and compliant with quality standards. EN 300 328 certification represents an essential step for manufacturers who wish to market their wireless devices on the European market, ensuring compliance with standards and customer satisfaction.

The purpose of the EN 300 328 standard for wireless products is to ensure that radio equipment operating in the 2.4 GHz Industrial, Scientific, and Medical (ISM) band, and also used for Wideband Transmission Systems (WTS), can be used safely and effectively without causing harmful interference to other radio services. It establishes key technical requirements related to: * **Effective Use of the Spectrum:** The standard aims to ensure the efficient use of radio spectrum by defining parameters for transmission. * **Protection of Other Radio Services:** It sets limits on unwanted emissions and mandates that equipment must not cause harmful interference to other licensed radio services. * **Device Functionality and Performance:** It specifies requirements for the reliable operation of the wireless device itself. Specifically, some of the key technical requirements it establishes include: * **Transmitter Output Power:** Limits on the maximum radiated power to prevent excessive signal strength. * **Frequency Stability:** Ensuring the transmitted frequency remains within a specified range. * **Occupied Bandwidth:** Controlling the width of the frequency band occupied by the transmitted signal. * **Spurious Emissions:** Limiting emissions outside the intended operating bandwidth. * **Receiver Selectivity and Sensitivity:** Defining performance criteria for the receiver to correctly detect signals in the presence of other signals and at low signal strengths. * **Adaptive Frequency Hopping (AFH) and Listen Before Talk (LBT):** For certain technologies like Bluetooth, the standard mandates the use of mechanisms like AFH and LBT to avoid interference with other users of the 2.4 GHz band. AFH allows devices to dynamically hop to unused frequencies, while LBT involves checking if a channel is free before transmitting.

Good morning,
The objectives of EN 300 328 are mainly to ensure that radio devices use the spectrum efficiently, to avoid harmful interference between devices and to ensure that they can coexist in the same band.
Among the key points of the regulation are:
– efficient use of the radio spectrum: devices must transmit in a controlled manner;
– limited transmission power: devices must not exceed the intended power limit to reduce interference;
– spectrum access: devices must use techniques to avoid collisions with other devices;
– emission requirements: devices must control out-of-band and spurious emissions to avoid interference;
- signal robustness: devices must maintain adequate performance.
