Why Indoor DAS Is Essential for 5G

Did you know that nearly 80% of all mobile data usage happens indoors? Yet, 5G signals, especially those operating in high-frequency bands like mmWave, struggle to penetrate concrete walls, metal structures, and glass façades. That’s where the 5G distributed antenna system steps in. These systems act like mini cell towers inside buildings, ensuring strong, seamless coverage in offices, hospitals, malls, airports, and stadiums.

From uninterrupted video calls to critical telehealth services, distributed antenna 5G infrastructure is essential for achieving high-speed, low-latency connectivity indoors.
