What is a GSM antenna?

GSM Antenna is one kind of Antenna to transmit GSM signal at specified frequencies 850, 900, 1800, 1900, 2100MHz. 2100MHz is separated into UMTS (Universal Mobile Telecommunications System) frequency band for 3G and other frequencies are separated into 2G.

Rubber Duck Antenna Applications

The GSM series has three main parts, GSM900, DCS1800, and PCS1900, and the main difference between the three is the difference in the working frequency band.

The emergence of cellular mobile communications can be said to be a revolution in mobile communications.

Its frequency multiplexing has greatly improved frequency utilization and increased system capacity, and the intelligence of the network has realized trans-regional transfer and roaming functions, expanding the range of customer services, but the above analog system has four major disadvantages.

No public interface between systems.

Difficult to carry out data-bearing services.

low spectrum utilization cannot adapt to the demand of large capacity.

Poor security and confidentiality, easy to be eavesdropped on, easy to do “fake machine”.

Especially in Europe, there is no public interface between the systems, can not roam between each other, causing great inconvenience to customers.

GSM digital mobile communication system originated in Europe.

As early as 1982, Europe has several major analog cellular mobile systems in operation, such as the Nordic multi-country NMT (Nordic Mobile Telephone) and the United Kingdom’s TACS (Total Access Communication System), other countries in Western Europe also provide mobile services.

At that time, these systems were domestic systems and it was not possible to use them abroad. In order to facilitate uniform use of mobile telephony throughout Europe, a common system was needed.

In 1982, the Nordic countries submitted a proposal to the CEPT (Congress of European Postal and Telecommunications Administrators) for a public European telecommunication service specification in the 900 MHz band.

At this conference, a “Group Special Mobile” (GSM) was established under the Technical Committee of the European Telecommunications Standards Institute (ETSI) to develop standards and proposals.

The GSM Group was established at the Congress under the Technical Committee of the European Telecommunications Standards Institute (ETSI) to develop standards and recommendations.
