What is a mobile phone signal booster?

Most people are curious as to what a mobile phone booster actually is. The answer is simple, but less us give you some background first. In this era of globalization, wireless technology has been growing by leaps and bounds for several decades now. Cell phones, or mobile phones as they are also known, are the most widely used medium of communication. These phones work off of wireless networks. The UK has several network carriers, one of the biggest is Vodafone. Over the years, the network carrier industry has increased its scope to cover most of the country but there is still a large part that has signal issues. Parts of the country are still left out of full, reliable coverage. Signal boosters for mobile phones come can fix those problems. The Mobile signal repeater is a device that attracts signals from the air through an outdoor unit (usually outdoor antenna) and transmits it to an indoor unit boosts the signal. The transmission is conducted through a wired connection between the outdoor antenna and the indoor booster unit. The indoor signal booster has complex circuitry, and in turn, amplifies the signal with the help from a source of power. The gsm

then sends the amplified signal to the indoor antenna connected to the unit and the antenna transforms the received electrical signal into waves of the same frequency as received by the outdoor antenna. The received frequency range is non-varying in nature, so mobile phones do not notice any change in the frequency except for amplified signal strength. So basically, a mobile phone booster is a device that effectively boosts the mobile signals you receive. The complex circuitry incorporates external power and boosts the signal strength to the required threshold. How Mobile SIgnal Boosters work? It is crucial to understand the functionality of the GSM booster. This is a step-by-step analysis of how the different levels work involving signal boosters for mobile phones.

  1. The cell phone signal booster comprises an outdoor unit (a directional antenna) that detects and receives the signal from the air. These signals have very low strength and are very difficult for a mobile phone to detect them. The reason is that a very small antenna is embedded inside the cellular device. The outdoor antenna is much larger and is able to collect the signal easily, which goes untraced by the mobile phone.
  2. The collected “poor” signal is then moved through the wired medium and bypasses the local obstruction and is finally fed to the booster or amplifier. This is usually performed to make sure that the signal is not weakened further while reaching the indoor unit through the conduction medium.
  3. In the indoor unit, the booster performs the amplification process by superimposing the frequency of the carrier waves to the actual faint signal that in turn strengthens the signal overall. The booster is reinforced with power provided by the power outlet to perform the amplification
  4. The amplified signal is then transferred to the indoor antenna that broadcasts the signal throughout the coverage range. In this range, the mobile devices receive the stronger signal, different than their original signal from their carrier. The GSM signal booster makes all this possible.

Are Mobile Signal Boosters safe?

Today we are surrounded by a huge number of various devices and gadgets and whether we believe it or not every device emits a certain amount of radiation in the atmosphere whether it is your TV, your Radio or personal computers and devices of such like. These radiations influence us in one way or another. People are seen often arguing upon whether Mobile Signal Boosters are safe to be around us or not. Debates are still going on about the safety of the mobile boosters in UK and the views are conflicting. We are surrounded by electromagnetic radiations emitted by various devices all the time and adding a mobile network booster with a low powered signal won’t increase the electromagnetic radiation limits dramatically. Studies and researches have shown that a Mobile Phone Signal Booster hardly possesses any risk towards human health. The impact of mobile network booster is very cursory. It is because of the reason that the power emitted by the amplifier is very low and even multiple mobile network boosters are added into the system, there will hardly be any variation in the emitted power. Interestingly mobile phone, on the other hand, is considered more harmful according to various conducted researches and studies. This is prominent by the fact the mobile phone stays with a person all the time and remains in the nearest proximity, thus affecting the individual to a greater extent. What we should consider here is a fact, that in low network coverages, mobile phones tend to increase its input power to the inbuilt wireless receiver in order to catch the weak signal and thus emits increased radiations, whereas installing a Mobile repeaters will decrease the potential threat as due to increased signal strength, mobile phone receiver will exhibit less power. So ironically, you can save yourself from harmful radiations of the mobile phones in the weak signal zone by having a mobile phone signal booster and numerous speculations about mobile phone reception boosters being harmful to have no ground at all.
