IBS Antenna
IBS Antennas are high-performance in-building antennas designed to provide seamless indoor wireless coverage for telecom, DAS (Distributed Antenna System), 4G, 5G, WiFi, and RF communication systems. These antennas ensure stable signal distribution, improved network coverage, low signal loss, and reliable communication performance inside commercial and residential buildings.
At SRFS Teleinfra, we manufacture premium-quality IBS Antennas engineered for efficient indoor RF signal coverage, high gain performance, low VSWR, and superior durability. Our IBS antennas are widely used in offices, malls, airports, hospitals, hotels, factories, underground parking, and large commercial infrastructures requiring strong indoor network connectivity.
IBS antennas are specially designed for indoor RF coverage applications where outdoor cellular signals become weak because of concrete walls, steel structures, and dense infrastructure. These antennas help distribute RF signals uniformly throughout the building for seamless voice and data communication.
