It is CAE’s mostly used transmission system, because of its capacity to allow safe and constant data flows, less exposed to overload problems and suitably quicker in comparison to other technologies. Through radio, data reach all users in real time, even during the most congested emergency situations, when perfect efficacy is not only desirable but a must. |
The GSM/GPRS technology, although an experimented technology for data transmission, is not exempt from line drops or even important delays in message delivery, when excessive traffic or congestion of radio mobile supported networks occur. These critical conditions mainly occur during hydro-meteorological emergencies, due to the high traffic flow of personnel and rescuing means employed for the management of the emergency itself. For this reason the GSM / GPRS technology is used by CAE mainly transmission of data, faxes or text messages, when real time acquisition should not granted as absolute priority. Opposite to this, radio transmissions remains the best option when reliability of data and immediate response are a must. For these reasons, GSM / GPRS communication systems are often combined with radio technology for the creation of service channels, which are able to integrate radio communication for the implementation of operations such as remote control, software upgrade in the field stations, acquisition of images and so on. |
The satellite system is useful when it’s impossible or not convenient to provide adequate radio coverage, due to topography or particular features of the area to be monitored. |
