 (i.e. mountains) and buildings, technology and radio frequency. Some frequencies provide better regional coverage, while other frequencies penetrate better through obstacles, such as buildings in cities.

The ability of a mobile phone to connect to a base station
Base station
The term base station can be used in the context of land surveying and wireless communications.- Land surveying :In the context of external land surveying, a base station is a GPS receiver at an accurately-known fixed location which is used to derive correction information for nearby portable GPS...

 depends on the strength of the signal. That may be boosted by higher power transmissions, better antennae and taller antenna masts. Signals will also need to be boosted to pass through buildings, which is a particular problem designing networks for large metropolitan areas with modern skyscrapers. Signals also do not travel deep underground, so specialized transmission solutions are used to deliver mobile phone coverage into areas such as underground parking garages and subway trains.

Coverage noticer

A coverage noticer is a device that beeps (or vibrates) when in a zone that lacks coverage (white spot). This is fundamental for critical services (security, emergency and so on). When the user goes to a covered area, the noticer ceases beeping.

It can be integrated in a mobile phone
