CEL-FI QUATRA is the only system certified by the FCC to amplify outdoor signal by 100 decibels. That means it can cover large buildings with signal from nearby towers, without needing carrier approval or costly signal sources.

At the heart of Nextivity’s CEL-FI QUATRA product line is the IntelliBoost chipset, a custom, patented ASIC that delivers unrivaled performance. With digital filtering, echo cancellation, signal demodulation and much more, no other off-air signal boosting technology comes close.

CEL-FI QUATRA is the only DAS that amplifies and rebroadcasts outdoor 4G & 5G signal over regular ethernet cable, with the option of using fiber cables to cover longer distances.

Every QUATRA comes with Cel-Fi’s WAVE cloud monitoring platform included. Whether it’s connected to Waveform’s Network Operations Center or monitored by your IT team directly, monitoring access is just a click away.

Thanks to a modular and expandable system, QUATRA can scale to cover from tens to hundreds of thousands of square feet.
