Ensure your team stays connected with dependable voice and data coverage throughout your building. With ARO’s in-building mobile coverage solutions, you’ll eliminate mobile black spots and provide consistent connectivity across all locations and levels of your built estate.
Building layouts and materials—like concrete walls, metal frames, and dense insulation—can create mobile black spots, causing call dropouts and poor connectivity. While minor interruptions might not affect smaller teams, larger businesses with hundreds of users experience lost productivity and missed opportunities from every missed call.
ARO specialises in in-building coverage solutions designed to target and eliminate these connectivity gaps, creating a seamless mobile experience for your workforce.

In-building coverage solutions are technologies and strategies designed to enhance and extend mobile network signals within buildings. These solutions address the challenges of weak or inconsistent mobile signals experienced in large structures.
An in-building coverage solution eliminates signal black spots, ensuring reliable voice and data service across all areas of your building. This reduces call dropouts, improves connectivity, and enhances overall productivity.
TARO customises solutions to fit building layouts, materials, and environmental factors. Our team assesses each building’s unique needs and uses technology such as small cells and distributed antenna systems to target problem areas.
To improve mobile signals in buildings, businesses can install signal boosters or repeaters, utilising distributed antenna systems (DAS), and optimising building materials to reduce signal interference. Additionally, Wi-Fi calling and in-building wireless solutions can be implemented to enhance mobile connectivity within the building.
