What is a GSM antenna?
 

The GSM (Global System for Mobile Communications ) is a standard developed by the European Telecommunications Standards Institute (ETSI) to describe the protocols for second-generation (2G) digital cellular networks used by mobile devices such as mobile phones and tablets.

2G networks developed as a replacement for first-generation (1G) analog cellular networks. The GSM standard originally described a digital, circuit-switched network optimized for full-duplex voice telephony. This expanded over time to include data communications, first by circuit-switched transport, then by packet data transport via General Packet Radio Service (GPRS), and Enhanced Data Rates for GSM Evolution (EDGE).

GSM networks operate in a number of different carrier frequency ranges (separated into GSM frequency ranges for 2G and UMTS frequency bands for 3G), with most 2G GSM networks operating in the 900 MHz or 1800 MHz bands. Where these bands were already allocated, the 850 MHz and 1900 MHz bands were used instead (for example in Canada and the United States). In rare cases, the 400 and 450 MHz frequency bands are assigned in some countries because they were previously used for first-generation systems.

What is a GSM antenna used for:

The GSM standard is the most common application for the mobile communication field global. GSM is Global System for Mobile communication and is the most popular standard for mobile phones. GSM Antenna will boost the signal strength in receiving and transmitting.
