In order to increase the speed of receiving and transmitting data to the Internet, it is necessary to install an external antenna for 3G modem .
Consider ways to install and configure an external antenna.
An antenna fixed to the mast is connected to a 3G modem using a pig-tail adapter. The modem must be connected to the PC and run the accompanying software. In the program that comes with the modem, we are looking for a line indicating the level of the modem signal. When you bring the cursor to the scale, the value dbi will be displayed. Next, smoothly rotate the antenna around the mast and monitor changes in the signal level using the running program. Note that the signal indicator changes its value with a delay of 20-30 seconds. The best signal quality is observed when dbi is closer to 0. After the best position is found GSM communication antennas , it is necessary to tighten the clamping nuts.
Do not forget that in case of commissioning by operators of additional base stations, or simply building new houses near you, the level of the received signal may deteriorate. To remedy this situation, the gain antenna for the 3G modem is re-configured.
Consider the types of antennas for 3G modems.
Whip antenna for 3G network
It has a signal gain up to 5 db. In this regard, is used only in cars, in order to avoid the manifestation of the shielding properties of the car body. Whip antenna has another name - "circular", because it has a radiation pattern of 360% and does not require any adjustment. However, due to low efficiency is rarely used. The radiation pattern is the dependence of the antenna gain on the direction of the antenna in a given plane. In other words, it is the angle of the antenna towards the base station, providing maximum gain.
Log-periodic antenna for 3G network
An antenna of this type can be made with almost any gain. But, most often, manufacturers do not manufacture a log-periodic antenna with a gain of more than 14 dB. This is due to the increasing bulkiness and difficulties in installing the device. These antennas are made because their design does not cause difficulties in the manufacture and installation. Special accuracy is also not required. Most log-periodic antennas have a radiation pattern of about 50%, which simplifies their setup. However, due to their large dimensions, log-periodic antennas are not very popular.
Antenna type wave channel for 3G network
Unlike the above antennas, the use of a wave channel antenna to enhance the speed of the Internet is the best option. Such antennas are made with a gain of 5 to 21 dB. In order to obtain a higher gain, the following steps should be taken: an even number of identical antennas should be connected to the antenna array by means of a wave transformer. The popularity of wave channel antennas is determined by a radiation pattern of about 30–40%.
