Project Overview

• Location: Dublin, Ireland

• Property Type: Villa underground garage (fits 4 cars)

• Layout: Single basement level, approx. 100 sqm

• Issue: No mobile signal in the basement, affecting smart garage door, CCTV, and security app usage

 Challenges Faced

• Complete signal loss due to reinforced concrete walls and underground location

• Need to deliver strong 4G signal without interfering with the upper floors’ coverage

• Required discreet cable routing to maintain the clean interior look

• Client wanted seamless integration for smart devices and emergency calls

 Our Solution

We installed a dual-band signal booster (900/1800 MHz) for Ireland carrier frequencies (Vodafone, Three, Eir):

Installed Components:

• 1 × outdoor panel antenna mounted at ground level outside the garage entrance, aligned toward nearest tower
• 1 × high-gain indoor panel antenna mounted inside the garage ceiling for targeted coverage
• Low-loss coaxial cable routed through concealed wall conduits
• Amplifier unit installed in a wall-mounted utility box with ventilation slots

 Results Achieved

• Full mobile signal coverage inside the underground garage
• Reliable operation of smart garage door opener and CCTV live view
• Security apps function smoothly for real-time alerts
• Client feedback:

“The garage now has the same strong signal as the rest of the house — I can even stream music while working on my car”
