Wi-fi antenna - a radio engineering devices, which serves to transmit or receive wireless signals Internet wi-fi. Matter of choice wi-fi antenna stands in front of the people, that, undoubtedly, They want to get high-quality and fast internet. As is well known wi-fi antenna is the most important component for the wi-fi stations, because it is the choice of the antenna will affect the data transmission speed and the fact, as the transmission signal will be implemented at different distances. For, not to be mistaken in choosing a wi-fi antenna, should be good to learn about all the classification parameters.
Types of wi-fi antennas
Wi-fi the antenna can be divided into three types: frequency, Polarization and Directionality.
The main types of wi-fi frequency signals on the antennas is an antenna for the frequency range 2,4 GHz 5 GHz. Wifi antenna in the direction of directional antennas are divided into, sectored antennas and omni-directional antennas.
Depending on the polarization of the wi-fi antenna can be divided into odnopolyarizatsionnye and dvupolyarizatsionnye.
The use of wi-fi antennas
Consider, to begin wi-fi antenna signal frequency. It should be noted, that stations with frequencies 2,4 GHz characteristic is their low sensitivity to obstacles, but they have the ability to combine with other instruments. Also pay attention to the fact, that their range is very noisy. But the wi-fi antenna 5 GHz in their characteristics are slightly better.
One variety of wi-fi antenna is a directional antenna, which has the ability to transmit signals in a given direction, that it is carried out by using a focused beam. It should be noted, that this type of antenna, by virtue of their characteristics, It does not apply to base stations, as, eg, very rare network clients are located in a very narrow band of the signal.
Sectored antennas tend to distribute the signal in certain sectors. This type of antenna operates fully in sectors from 60 to 120 degrees. In most sectored antennas used for constructing omni base stations. But omnidirectional antennas already make it possible to create a wi-fi coverage around, for all 360 degrees.
In addition to these types of wi-fi antennas, there is odnopolyarizatsionnye and dvupolyarizatsionnye, which is also called AirMax and MIMO. The difference between them lies in the fact, that the first view is a conventional antenna, to connect that only one connector is sufficient.
But the second type of antenna has two connectors for connecting to the access point. Also, the latter kind has the advantage over the first that, such that the antenna is twice as fast transfers information using wi-fi, by its transmission in two streams, one of which is in the horizontal plane, and the other - in the vertical. Do not forget, that failing to choose the correct WiFi antenna, You, undoubtedly, get excellent quality and good data transfer rate, that will provide peace of your nervous system.
