Is it necessary to use high-power mobile phone signal repeater and high-gain antennas to achieve large-scale coverage of mobile phone signals? In fact, this needs to be considered on a case-by-case basis, but according to my experience in dealing with so many engineering cases, in most cases, a high-power mobile phone signal booster is used in conjunction with a high-gain antenna to achieve a wide range of mobile phone signal coverage.

    Aside from the fake and inferior mobile phone signal amplifiers on the market, when the signal booster is fully output, the coverage range is 10dBm, which can cover 100-300 square meters indoors; 15dBm output power, which can cover 200-600 square meters indoors; Output power 20dBm, indoor coverage of 600-1000 square meters; output power of 27dBm, indoor coverage of 1000-3000 square meters; output power of 30dBm, indoor coverage of 2000-5000 square meters; output power of 33dBm, indoor coverage of 3000-6000 square meters Meter, outdoor can cover 1-3 kilometers; output power 37dBm, indoor can cover 6000-10000 square meters, outdoor can cover 2-5 kilometers; output power 40dBm, indoor can cover 10000-15000 square meters, outdoor can cover 3-6 km; output power 43dBm, indoor coverage of 15,000-23,000 square meters, and outdoor coverage of 4-8 kilometers. Except for me, almost no one can tell you such specific parameters. Because it must be a good quality mobile phone signal amplifier to achieve the above effect. Then there is a concept called full power output, which I will explain to you later.

    Let me list some situations for you to understand when high-power mobile phone signal amplifiers and high-gain antennas must be used.

    The first situation is that the outdoor signal strength is very good, and there is no indoor signal. It needs to cover the mobile phone signal of several floors, and each floor exceeds 2,000 square meters. It is also one of the most demanding situations in daily life. Let me analyze the idea of choosing a mobile phone signal amplifier and antenna in this situation. First of all, the outdoor signal strength is very good, so there is no need to use a high-gain outdoor antenna, just use an ordinary outdoor antenna, because the ordinary outdoor antenna can already receive very good signals at this time. Then, according to the size of the coverage area, select the mobile phone signal amplifier of the corresponding power. But it should be noted that the above parameters do not calculate the space loss and cable loss. Capable friends still have to draw a picture or find a supplier for calculation to select a specific model. Because the three-story building assumes that each floor is 2,000 square meters and the first floor is 6,000 square meters, although the total is the same. However, in the actual coverage scheme, because the space loss is different from the cable loss, the selected mobile phone signal amplifier power is not necessarily the same.

    Then the second situation is that there is no mobile phone signal outdoors, and there is no signal indoors, and a large area of mobile phone signal needs to be covered. This situation is also the most common, but 9 out of 10 do coverage failures. Pay attention, the following are the details. Because there is no mobile phone signal outdoors, it proves that the ordinary outdoor antenna cannot receive the mobile phone signal transmitted by the base station. At this time, we should use a high-gain outdoor directional antenna, facing the direction of the nearest base station. In this way, relatively qualified mobile phone signals can often be received, but be careful, because there is no signal outdoors, using high-gain outdoor directional antennas can often only receive relatively qualified mobile phone signals. Therefore, at this time, the mobile phone signal amplifier cannot output full power.

    We compare the outdoor antenna to the mouth, and the outdoor signal is equivalent to food. If you are not full, where does the cell phone signal amplifier work? The reason why doing this type of signal coverage fails is that it ignores this. Therefore, the power of the mobile phone signal amplifier selected by the method mentioned above is not enough at this time, because it can no longer output full power. Keep testing with higher power cell phone signal amplifiers. Or ask the supplier to return a higher power cell phone signal amplifier.

    So the situation is different, and the matching signal amplifier is different from the antenna, but to cover a wide range of signals, a high-power mobile phone signal amplifier is indeed essential. It's just that the specific power required needs to be determined through field investigation and calculation.
