The first computer appeared in the world forty years ago. Then the world wide web was created - the Internet. The first internet was wired and it was available to the chosen few. But over time, the elect became more and more, until those who did not have the Internet became the elect. There were more and more ways to connect to the Internet, providers appeared almost every day. But if the Internet was available to residents of big cities almost everywhere, then what to do for those who do not have the opportunity to stretch the cable. But progress does not stand still, and finally, the mobile Internet was created. The signal is transmitted using the transmitting antenna of the mobile operator, and is received by the modem. Nowadays, no one will be amazed by the wireless 3G Internet, which allows everyone to get involved in the expanses of the Web from almost the first place in our universe, whether it be a chic mansion on the outskirts of the capital, or an open field, or a house by a river in a remote village. The main thing is to have a mobile device or laptop and a modem. But the problem is that not all places are not only far from the base station, but even the suburbs of large cities are "covered" by the communication of mobile operators.
Antenna assignment
Under these circumstances, antennas for modems will come in handy, thanks to which you can catch even the weakest signal from the operator in order to enjoy a stable Internet connection. Such an antenna resembles television antennas that are in apartments or in private yards. When choosing an antenna, you should take into account the terrain and the distance to the operator's base station. The greater the distance, the lower the signal quality is received by the modem, and the more it becomes necessary to use amplifying antennas. Depending on the conditions of use of the modem and the distance to the operator's antenna, it is necessary to select an antenna. It is needed to raise the signal level and can have different geometric shapes and sizes for different operators.
Antenna types
In large cities, where there are many stations and high-rise buildings, it is best to use omnidirectional antennas that have the ability to receive the reflected signal. They are placed outside the window or on the balcony. These can be automotive, panel, collinear or planar antennas.
When the modem is located near a city within sight of the base station, there may be no need for a powerful antenna. An indoor or car omnidirectional antenna is sufficient.
Antennas with different gain are selected depending on the distance between the modem and the operator's station. The longer the distance, the more gain is needed. Antennas can be of medium gain - such as 14dB or
