The Differences Between The GSM 3G 4G LTE Antennas

By Joyce Smith


When you plan on buying a new cell phone, surely, you might have a problem on choosing what kind of networks will you have. It maybe GSM, WiMax, CDMA, or LTE. So it would be very important on knowing the differences of these networks.

The simplest explanation for this would be the G in 4G means generation because this is the fourth generation of mobile data technologies. While for LTE, it stands for Long Term Evolution which is the improved type of broad bands that are wireless. This article is going to provide you on the ideas about the differences between the 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.

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 ITU or the International Telecommunication Union did not clarify the definition of the exact data rate that the users will expect upon using the 3G provider or equipment. And for this reason the users that will sold this service cannot be able to point out the standards, thus, saying that the specified rates are not met. These data rates include the minimum required rate, required average rate, and the interface modes that will qualify being 3G.

Third is fourth generation or 4G, succeeding the 3G network. Some uses of this include mobile web access, IP telephony, gaming services, HD TV phone, video conferencing, and 3D television. This refers to networks of IP packet switched type that provides a gigabit speed or ultra broadband access to mobiles.

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.
