Important Note: For large properties such as multi-storey corporate offices, hotels, shopping centres, and underground areas like basements and parking garages, you will require a Distributed Antenna System (DAS) to distribute boosted signal effectively across multiple floors and hard-to-reach zones. The HiBoost Hi23-3S signal booster is fully compatible with DAS setups, enabling improved signal distribution via multiple indoor antennas.
