European Countries Evolution of the regulatory framework PMR 446

ECC Report 369 examines the technical feasibility and implications of increasing the maximum effective radiated power (e.r.p.) of PMR 446 equipment from the current limit of 500 mW to 1 W, while maintaining the requirement for the use of integrated antennas.

The study combines coverage and capacity simulations, minimal coupling calculations, statistical analysis using the SEAMCAT tool, and monitoring campaigns in several European countries.

The report concludes that there is a trade-off between coverage gains and capacity reductions. However, the current level of band usage demonstrates that the available spectrum is sufficient to accommodate the introduction of 1 W PMR 446 equipment. Therefore, the modification of technical parameters can be implemented without compromising the existing ecosystem or quality of service, ensuring that PMR 446 remains an effective and flexible tool for short-range communications in both personal, recreational, and professional contexts.

WHOM DOES IT IMPACT?

The direct impact is on PMR 446 equipment manufacturers, end users, and regulatory authorities.

CONCLUSION:

Increasing PMR 446 power to 1 W is a technically feasible and sustainable measure within the actual spectrum usage. Although it reduces theoretical capacity, the current low occupancy ensures that the change benefits users without compromising coexistence or spectral efficiency.
