Indoor RF Troubleshooting and Enhancement

Indoor RF Troubleshooting and Enhancement

A property management company in Singapore experienced serious wireless connectivity problems inside a newly constructed commercial tower. Employees and guests reported frequent dropped calls, slow network speeds, and poor coverage in conference rooms and elevator lobbies.

• Diagnostics and Site Evaluation: The consulting process began with an RF health check across several floors using spectrum analysis and field strength mapping. Wireshark and TEMS Discovery tools identified dead zones and sources of interference from building infrastructure and dense exterior deployments.​

Solution Development and Deployment: Key solutions were implemented:

• Designed and installed strategically placed indoor small cells to supplement macro network coverage and boost signal strength within critical areas.
• Used polarization diversity and optimized antenna placement for optimal signal propagation through walls and between floors.
• Advised on LTE and VoLTE optimizations, including handover parameter tuning for seamless mobility within the building.
• Provided a network plan adjusting frequency allocations, leveraging local 5G gNBs and 4G nodes for targeted performance.​

Outcome and Impact: Post-deployment analysis showed:

• Complete coverage in previously inaccessible zones.
• 25% reduction in dropped calls and handover failures.
• Reliable high-speed data access throughout all business units, greatly improving operational effectiveness and guest satisfaction.
