When you are planning to buy a cell phone, for sure, you will be having problems most especially in the selection of network that you would like to have. Your choices may be WiMax, LTE, GSM, or CDMA. Because of this, knowing these networks differences is important.

The most simple explanation for this is the G in a 4G means generation since it is the fourth generation for the technology in mobile data. While the LTE means Long term Evolution and this is an improved type of wireless broad bands. So this article will be giving you the ideas on the differences of GSM 3G 4G LTE antennas.

First is GSM or Global System for Mobile Communications. It is a type of cellular network in which the phones will connect through searching for any cells in the area or vicinity. Cells have different sizes in this network and these are micro, femto, macro, pico, and umbrella. Its area of coverage will be highly dependent on the implementation.

A micro cell is usually used in most urban areas. The micro cell antennas height is placed under a rooftop in average level. A femto cell is usually used in a residential environment or in small businesses. It is being connected to the service provider through a broad band connection. A macro cell is usually used in most buildings. The antenna will be placed on a rooftop above an average level.

Pico types are smaller and its coverage diameter is usually only few dozens in meters. Pico types usually are installed indoors. Umbrella types are used usually when covering shadowed regions of the smaller cells and also when filling up coverage of smaller cells.

Second is 3G. This is a short term for third generation and this is the third generation in the technology in mobile telecommunications. The basis of this are the standards that are used in the devices and the telecommunications are using networks and services that comply the specifications provided by the International Telecommunication Union. This type is being applied usually in phones internet access, video calls, wireless voice telephony, fixed wireless internet access, and phones TV.

The International Telecommunication Union or the ITU was not able to give a clarification on the definition of data rates in which the users expect when using this equipment or provider. And because of this, those users who are going to sold the service cannot point out some standards, and thus, the specifications on the rates were not met. Data rates include required average rate, minimum required rate, and modes of interfaces that qualifies as 3G.

Third is 4G or fourth generation and this succeeds the 3G. The applications of this would include IP telephony, high definition phone TV, 3D television, mobile web access, gaming services, and video conferencing. This refers to the IP packet switched network which gives the mobile an ultra broadband access or gigabit speed.

Fourth is LTE or Long Term Evolution. It is the standard used for the high speed wireless communications in data terminals and mobile phones. The speed and capacity have increased because of different radios interfaces being used together. It was marketed before as a 4G LTE but it was not able to meet the criteria of the 4G wireless network an LTE advanced.
