Losing signal underground? 📶
Poor mobile coverage in underground car parks, emergency stairwells, basements, and lift lobbies is more than an inconvenience — it’s a real safety risk for staff, tenants, visitors, and customers.
These areas are often the hardest for mobile signals to reach, yet they are the exact locations where communication becomes critical during emergencies.
Whether it’s a medical incident, fire evacuation, security threat, or vehicle accident, the ability to reliably call Triple Zero (000) can make all the difference.
Powertec's In-Building Coverage (IBC) solutions are designed to enhance cellular coverage inside buildings, hospitals, underground facilities, commercial towers, and other challenging indoor environments where mobile signals are typically weak or blocked.
Why reliable in-building mobile coverage matters:
✅ Direct Cellular Routing
Powertec's IBC solutions route emergency calls directly through available 4G and 5G mobile networks — a safer and more reliable alternative to Wi-Fi calling, which may not always accurately identify your location for emergency dispatchers.
✅ Reliable Triple Zero (000) Access
By delivering strong, consistent indoor coverage through Distributed Antenna Systems (DAS), occupants can reliably connect to nearby mobile towers and place free, life-saving emergency calls when every second counts.
✅ Consistent Connectivity in Critical Areas
From underground car parks and stairwells to hospitals, hotels, offices, and remote facilities, Powertec helps bridge indoor connectivity gaps to support reliable communication where it matters most.
Modern buildings need more than connectivity — they need resilient communication infrastructure that supports safety, compliance, and peace of mind.
