GSM frequency
European countries, such as France, Belgium, Spain, Germany, Italy and Switzerland, use GSM 900 and 1800 frequency bands. The United States, Canada and some Latin American countries surf the GSM 850 and 1,900 frequency bands.
The GSM 900 uses the 880-915MHz frequency band to transmit voice or data from a mobile, while the 925-960MHz frequency band is used to receive information from the network. The GSM 1800 uses the 1.710-1.785MHz frequency band to transmit data from a mobile terminal (upload). The 1.805 -1.880MHz band is dedicated to receiving information (download).
Devices that operate on both the 900 frequency band and the 1,800 frequency band are referred to as " Dual GSM band ». Those who use only the 1,800 frequency band are called the "DCS 1.800" (Digital Communication System).
The exploitation of the GSM frequency is overseen by an independent administrative authority responsible for overseeing the postal and electronic communication sector, in this case, ARCEP in France.
For example, in the field of mobile telephony, each GSM frequency band is subdivided into many channels divided by the regulator to the various operators. These channels can be used for transporting communications or transporting control information (signaling).
Individuals and businesses can use GSM frequency bands for a spy camera detectora spy camera detectora spy micro detector or for a micro camera. These devices use over-the-air waves on a GSM frequency band to communicate. Their update can be done with a signal detector.
