Searching for the best mobile Internet signal in spring 2015

    So spring has come to our land. Weather on the street + 5 degrees, summer work is resumed, and with it the search for a reliable mobile Internet provider. It is in the spring, when nature begins to wake up, the trees create additional electromagnetic radiation, the foliage closes the direct line of sight with the base station, and the task arises of amplifying the cellular signal. And in 2015, the solutions with the lowest costs were especially popular, and this will be discussed in this review.

    So, there is a summer cottage in a picturesque area surrounded by a pine forest, because of which residents of the cottage are not able to receive high-frequency signals from the Yota operator, although the distance to the working base station is only 1500 meters.



    To begin with, we traveled around the area, using a spectrum analyzer and a laptop, we chose a base station with the best bandwidth and the best signal for amplification. However, the 4G signal was not received at the device site itself. The analyzer showed a signal level of -105-110 dB.

    And what has not been tried here ...

    We started with the most budget option - a 4G wave channel antenna (1,490 rubles) with a declared gain of 17 dBi, the effect is zero, the modem does not see a 4G signal. Then they tried the URSA 4G panel antenna (18 dB), it did not give us anything (2000 rubles). The next AX-2520P MIMO 2x2 4G / LTE antenna (20dBi), next in terms of quality and price (4000 r), but the modem didn’t connect to the base station either, and then heavy artillery was launched - a system based on offset parabolic antenna. More on this.

    Of course, the use of the mast would simplify our life, but we came up against the price, then the customer chose the barbaric method of installing the plate on the nearest pine. We made every effort so that the tree does not suffer, but the result paid off.



    So, the Internet user's survival kit in the forest includes:

    1. Installation of the bracket (500 rubles) at a height of 10 meters.
    2. The offset antenna, aluminum (65 cm plate), KU 36 dB (3000 rubles). It is possible, of course, and more, but we have a small distance, it was just necessary to collect the scattered signal, so this was enough. The main thing is good quality plates. We decided for ourselves that we work only with Italian plates. The difference is significant, and there are always fewer dances with her.
    3. Illuminator for offset satellite reflector AX-2400 OFFSET MIMO 2x2 4G LTE (1100 rubles). The description says that with a 65 cm plate it will give 21 dB of gain, but we did more. A good plate works wonders. Our modem showed a signal level of 80 dB, the rest of the options failed.
    4. Cable assemblies. We used a blue cable 5D-FB Aileron 25 meters * 2 pieces, 4 N-type connectors, two pigtails (from N to CRC-9), total: 4450 rubles.
    5. Huawei E3272 modem (1800 rubles)
    6. ZyXEL Keenetic 4G II wifi router (2900 rubles) for signal distribution throughout the house.

    Thus, the equipment pulled a little, a lot at 13750 rubles (dancing with a tambourine is priceless). But this is cheaper than installing a 4G repeater, and taking into account the signal level - the coverage area from our solution is larger.



    As a result, 35-36 Mbit / s for downloading, transmission - 6 Mbit / s - this is quite enough, and the subscription fee is only 1400 rubles for unlimited, which can be reduced to any price, speed or traffic volume that is convenient for you. Of course, you can put “real satellite Internet” and pay 4,000–7,000 rubles per month for 4 Mbit / s, the transfer will be up to 0.5 Mbit / s, and the traffic limit is 20–25 GB.

    It’s up to you, but we know for sure that “expensive” is a relative term. As said, the old woman from the “Ural dumplings” - “Expensive Land Cruiser to refuel!”.
