Keeping It Quiet: STULZ delivers noise protection for Telecom Infrastructure in residential areas

As Europe continues its rapid rollout of full-fibre and 5G networks, telecommunications providers are facing a growing challenge: how to ensure reliable operation of PoP (Point of Presence) and RAN (Radio Access Network) stations while minimizing noise disturbance in densely populated or newly developed residential areas.

To maintain uptime and protect critical network equipment, PoP and RAN stations require stable internal temperatures — often achieved through mechanical cooling. However, these systems generate noise from compressors, pumps, and fans. Without proper acoustic planning, this can exceed regulatory noise limits and lead to community complaints, legal disputes, or costly retrofits.

Noise exposure, especially during nighttime hours, impacts public health and well-being. Regulations such as the EU Environmental Noise Directive and national standards define strict limits — often as low as 40 dB(A) at night — to protect residential zones. With increasing urban density, ensuring compliance is no longer optional. Moreover, once a station is built, retrofitting noise protection is far more expensive and complicated than planning it from the start. >> More

STULZ addresses this challenge with an integrated, future-proof approach. From initial acoustic site analysis to the development of high-performance, sound-insulated shelters, STULZ supports telecom providers at every step. By combining free cooling modules, low-noise air conditioning, and retrofittable silencers, STULZ solutions significantly reduce sound power emissions — often far below statutory limits.

In field tests, STULZ’s customized silencer solutions have reduced noise levels by up to 12 dB(A), making infrastructure practically inaudible — even in quiet zones.

By helping operators meet both regulatory and community expectations, STULZ enables smoother deployment of next-generation networks — without sacrificing peace and quiet.
