SPINNER RF Power Protector

Intelligent Protection for Active In-Building DAS Systems

Reliable indoor mobile coverage has become mission-critical—whether in office buildings, hospitals, airports, stadiums, or shopping centers. Distributed Antenna Systems (DAS) form the technological backbone of this connectivity. However, these systems bring a major challenge: high-power radio units must interface safely with extremely sensitive optical components designed for only a few milliwatts of input power.

The SPINNER RF Power Protector addresses exactly this gap. It is an innovative, industry-leading protection solution that makes active DAS networks safer, more energy efficient, and far more sustainable.

Why the RF Power Protector Has Become Essential

Modern mobile networks are more complex than ever. More frequency bands, shorter ranges, and higher capacity demands mean that over 80% of all data traffic now originates indoors. Active, fiber-based DAS solutions are indispensable—but they come with significant risks:

  • Radio units output high RF power, while optical modules tolerate only very low input levels

  • Software-based power control can fail during updates

  • Excess RF power can destroy optical components within seconds

  • Classical attenuator-based solutions waste energy and generate unnecessary heat

The result: risk, inefficiency, and higher operational costs.

The SPINNER RF Power Protector eliminates these issues—automatically and reliably.

The Solution: Smart Protection Without Compromise

  1. Continuous power monitoring to protect sensitive components
    The RF Power Protector constantly monitors the radio’s output power and instantly prevents excessive input levels. High-value optical master units and other active components remain fully protected at all times.
  2. Significant energy savings through genuine low-power operation
    With the RF Power Protector in place, radios can safely operate in low-power mode, drastically reducing energy consumption and heat generation. This directly optimizes operational efficiency and reduces system cooling requirements.
  3. Sustainable alternative to inefficient attenuators
    Instead of burning excess RF power as heat, the RF Power Protector enables energy-efficient, eco-friendly DAS operation—an important contribution to CO₂ reduction and modern sustainability goals.

More Safety, Less Energy, Maximum Efficiency

The SPINNER RF Power Protector addresses the most pressing challenges of modern indoor mobile networks. It safeguards critical components, reduces operating costs, and enables sustainable, future-ready DAS infrastructures.

Safe. Efficient. Future-proof.
The SPINNER RF Power Protector sets a new benchmark for protecting active mobile communication systems.
