How many times have we had experiences of poor cellular coverage: poorly covered areas of the house, garages, elevators, basements? And with little range, not only do phone calls work poorly, but the data connection limps and the smartphone consumes twice as much power and heats up. Luckily there is a solution, and it is not hoping for the “clemency” of the telco in question. Simply extend your coverage with an indoor mobile phone signal booster – anyone can install it.
Why do we have a bad mobile connection?
The loss of mobile communication has happened to everyone and continues to happen. Just like phone calls that drop and data connections that hit the lowest possible bitrates. Of course, fiber optic and good Wi-Fi solve almost everything, except for the classic phone calls that end up ringing in bits and pieces.
But it’s not just a communication problem: there’s also a problem of consumption and electromagnetic pollution. When the signal is weak, the smartphone works at full power trying to maintain contact with the base station, which degrades electromagnetic radiation and battery life. The smartphone, even when it is not doing anything, heats up and discharges the battery. The solution is an indoor or outdoor mobile phone signal booster, for example by UCtel, capable of restoring the signal where it is, and transmitting it to where it is weak.
Who can use mobile signal boosters?
Even as the government tries to roll out digital technology across the country, some remote areas or rural areas struggle to get quality network coverage. This is why mobile signal boosters are aimed at people who feel that their network is not sufficient for their usage. This type of device will allow you to enjoy sufficient network coverage for your daily life. If you choose a mobile GSM signal booster, they will allow you to transport your equipment on the go. You will be able to use it while on vacation, during boat trips or in a motor home.
How do mobile phone signal boosters work?
The principle of indoor mobile signal booster is simple: take the signal where it is available and bring it to where it is scarce.
In most cases, faced with poor cell coverage or unable to enter less exposed parts of buildings, it is believed that the only hope is to contact the telephone operator for intervention: this is practically an impossible mission, given that it is only called EE or Vodafone and complain about poor coverage in your home, so they can get technicians out to the antenna immediately to boost the signal.
But not everyone knows that the easiest thing to do without asking anyone’s permission is to receive a signal where it is available (for example, on the roof of a building or just on the other side of the house, from the side of the base station) and transmit it there , where this is not enough.
In order for the system to work, it is enough that the external signal, at the “tap” point, is between -65 and -30 dBm: the amplifier and antennas placed inside will take care of the rest.
Mainly today, telephony uses five bands:
- 800 MHz (LTE or 4G);
- 900 MHz (GSM);
- 1800 MHz (DCS, LTE or 4G);
- 2100 MHz;
- 2600 MHz (LTE or 4G).
What does the amplifier consist of?
The architecture of these systems, for example, by UCtel, is very simple: external and internal antennas, between which there is a dual-band amplifier. The external antenna is responsible for capturing the signal coming from the base station (so to speak, the antenna of the telephone operator) and transmitting the signal generated by local telephones to it; the indoor antenna spreads the field indoors, thus guaranteeing cellular coverage.
Indoor and outdoor antennas are generally equivalent and interchangeable, but outdoors, if possible, we use a directional model: it is more efficient and picks up a stronger signal; but it only works well if you point well to the nearest base station. To best point the antenna, you need a field meter, without which it is difficult to accurately determine the direction to the base station.
Alternatively – and in many cases it is preferable – you can choose an omnidirectional antenna capable of capturing the signal in 360 degrees: An omnidirectional antenna is the best solution for city centers and systems where you want to serve many users. : in this way, the system receives signals from several cells and routes calls to them, minimizing the risks of network congestion that can arise from targeting a single system.
The amplifier and two antennas are connected by a cable. The cable can also be very long, but to avoid losses, the longer it is, the more it should have a large diameter. It happens that you need more than one antenna for indoor coverage, for example, if you need to serve more than one floor or very large areas: this is not a problem, just add a passive splitter that multiplies the signal through several cables; obviously the amplifier must be sized to support a more generous distribution.
Radio waves and health: can amplification cause problems?
One of the most common questions is whether a stronger cell signal, such as at home or in the office, can lead to increased health risks, if any.
When we talk on the phone and the signal is bad, the smartphone pushes the power to the maximum to reach the base station, which may be several kilometers away, and this can be the biggest problem. Because you keep it in contact with your head. If instead we have a booster system, our cell phone will only need to reach an internal antenna located a few meters away, and will therefore use a fraction of the transmission power it would otherwise use. So, this way, not only does the connection become more stable (including the data connection, obviously), but it also reduces the personal exposure to electromagnetic waves and battery consumption.
