Digital Fiber Optical DAS supporting 4G, 5G and Emergency Services across 1800/2100/3500MHz frequency bands. This 2Watt Digital Optical Repeater System features 33dBm Digital Optical dual band 1800/2100/3500MHz Amplifier DAS Repeater technology.

Distributed Antenna System (DAS) remains the most effective and reliable solution for in-building wireless coverage and capacity. As people spend most of their time in indoor environments, reliable wireless connectivity has become essential. Modern networks must support both voice traffic and high-volume data from smartphones and connected devices, requiring sophisticated DAS designs with high Signal-to-Noise plus Interference Ratio (SNIR) for optimal throughput.

ATNJ integrates small cells and Wi-Fi solutions into our portfolio, providing comprehensive wireless network coverage. Small cell solutions target small to medium enterprises with focused coverage and capacity, while Wi-Fi solutions help offload network traffic in hotspot areas.
