Amplify Mobile Signal with Stella Doradus

Why underground carparks have no mobile coverage?
While the mobile signal may be strong outside, it typically disappears once customers drive into an underground carpark. Poor mobile coverage in such locations is due to the concrete construction of the carpark and the fact that it is usually underground.
As a result, the visitors are unable to make phone calls or use mobile apps. Emergency services cannot work. E-charging meters cannot function properly.
Why do your clients need mobile coverage inside the carpark?

Always connected world
In today’s world, people expect to be able to use their mobile phones for calls and data everywhere, including underground carparks. When people experience poor mobile coverage or no coverage at all, they attribute this negative experience to the premises, in this case the carpark and the businesses associated with the carpark.
Health & Safety
The ability to make phone calls is critically important in case of an emergency. Strong mobile signal enables quick communication with emergency services such as Ambulances, Fire Brigades and Police. Nowadays police officers wear body cams which simply do not work without cellular signal.Â
EV Charging
Most EV-charging stations require a mobile signal in order to connect to their server. Also, strong mobile signal is essential for using mobile apps so that customers can seamlessly activate the service and pay for the EV-charging. Poor mobile coverage disrupts the EV-charging services and turns customers away.

An external antenna is installed outside the building where it receives signal from all mobile operators.
