Meaning
Harmonized standard specifies evaluation methods to demonstrate that radio base stations do not exceed safe human exposure limits for electromagnetic fields. Following the en 50385 standard is required to verify the safety of fixed wireless access points and small cell equipment prior to commercial operation. The scope of this standard applies to equipment operating in the frequency range up to three hundred gigahertz.
Basic Exposure
Evaluation of fixed wireless transmitters under the en 50385 standard involves calculating or measuring the power density at a specific compliance boundary. If the device operates at a low power, simple exclusion rules may apply. However, for higher power base stations, engineers must perform physical measurements or numerical modeling using electromagnetic simulation software.
These simulations verify that the public exposure limits are respected in all accessible areas.
Compliance boundary
Compliance with the standard is a necessary part of the product documentation for the European market. Operators of the network must also ensure that the installation boundaries are marked to prevent unauthorized access. This safety zone represents the area where exposure could potentially exceed the basic limits.
Compliance Certification
Documentation proving conformity with the en 50385 standard must be kept in the technical file for regulatory inspection.
