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, Global System for Mobile Communications or GSM. GSM is a cellular network where the phones will be connected by searching some cells that are just located in the same area. In this network, the cells are of five different sizes, these are the pico, macro, femto, micro, and umbrella. These cells coverage area depends on its implementation.

Micro cells can often be seen as being utilized by the urban areas and its antenna height is under the rooftops in an average level. Femto cells can often be seen as used in the small businesses or in the residential environments. These are connected to service providers via broad band connections. Macro cells are often used in buildings and the antenna is placed on rooftops above average level.

The pico types usually are small where in the usual diameter of its coverage area is only a few dozen of meters. These types are used indoors. The umbrella types usually are used for covering the shadowed regions of cells that are smaller and for filling up the coverage in those smaller cells.

Second is third generation or 3G. This is mobile telecommunication technologies third generation. This is based on the standards provided also for the in common devices. The telecommunications have been using the services and networks that comply to the specifications of International Telecommunication Union. The 3G type is applied most often in fixed wireless internet access, wireless voice telephony, video calls, phones internet access, and TV in phones.

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. It is one of the standards that is utilizing the wireless communication in high speed for the data terminals and for the mobile phones. The capacity and the speed are increasing due to utilizing the different radio interfaces altogether. This was marketed formerly as the 4G LTE but has not acquired the criteria of 4G wireless networks as advanced LTE.
