Why CEL-FI QUATRA Offers Better Coverage and signal Strength than Passive DAS

One of the issues with passive DAS (pDAS) or BDA (bi-directional amplifier) systems is that the cellular signal loses strength – also known as attenuation – the further the distance the remote unit is from the head end. That’s because pDAS is an analog system in which cellular signals are distributed over coax cable that […]
