What is a GSM Antenna

GSM Antenna Definition

GSM antenna is a type of antenna commonly used in mobile phones and cell towers. The GSM there means global system for mobile, which is a common standard for global mobile phone market. GSM antenna is used in a GSM phone, which allows the phone to communicate with another GSM antenna on a cell tower and then transfer the signal to another tower of cell phone based on the satellite communications technology.

There are many advantages to using GSM technology, which includes:

• Support worldwide roaming
• The capacity to replace services with a same cellphone
• The capacity to send text messages

Make a universal emergency number achievable, as you can call emergency services globally even without knowing the local number.

GSM service have been widely used on a number of radio frequencies, depending on the region and technology used. In order to meet the needs of different countries and areas, many phones will support a variety of these frequencies.

What is the use of GSM Antenna

1. GSM Antenna for mobile phones

Most modern mobile phones use internal GSM antenna to ensure the pretty look, and the antenna usually located in or near the bottom of the phone. But at the beginning, some manufacturers use the external pull-out antenna design or make the small bump of an antenna on the top of the phone. So the internal and external GSM antenna is all available and they works in a same way.

Beside the call function, more smartphones used additional technologies for the antennas, such as wireless Internet connections and data transfer, which used for sending email or web browsing.

2. GSM Antenna for cell site

Cell phone carriers use much larger antennas as part of their cell site. These can be mounted high on a tower or structure. A cell phone often is within range of more than one cell site, and it selects one to use for a call or data transfer based on signal strength and congestion. Carriers sometimes will hide a large GSM antenna or disguise it to make it look more appealing.

3. GSM Antenna for computer of usb device

A GSM antenna also can be found in a laptop, a netbook or a Universal Serial Bus (USB) device. In these cases, the antenna is meant only for data. It usually will use 3G/4G technology to deliver quick wireless Internet service over a GSM network.

4. Other application of GSM Antenna

In areas with poor coverage, special devices are designed to increase or extend the cell phone signal, typically for more reliable indoor use. These devices, which can be called femtocells, microcells or GSM booster antennas, have larger antennas than those found on mobile phones but smaller than those of a traditional cell site. The device uses its larger antennas to reach distant cell towers, and it provides a strong signal to nearby phones that otherwise would receive a poor signal or no signal.
