The question arises that how to choose the best cell phone booster? Cell phone signal booster is not very complicated, rather is very simple device with much information. It requires strong attention while installation so as to work smoothly. What you need to understand is the term used for power through which signals are to be transmitted. This power is measured in units called dBm like cm/m/km which are used to measure the distances, in the same way dBm is used to measure the power for transmitting the signals to the cell phone signal amplifier. For example, if the distance of your cell phone from the tower is 30ft then the power will be around 300 dB in wireless for transmitting signals. When low signal strength is converted in to high signals then the limits to be measured is to be decided by the ability f cell phone signal repeater. Suppose if the range of phone booster is 200ft then also the cell phone booster will work but after crossing the 200ft area the signals will lose its strengths.
Problems faced by people while installing:-
Some people have tried to install YAGI antennas in hilly areas for removing signals problems but they forgot that YAGI antenna cannot produce so much signal strength to cover full hilly area, it has its own limitations. So it is clearly understood that in order to cover large area then large boosters should be required. For these outside or hilly areas cell phone antenna repeaters are specially made for this purpose only. The range of these boosters’ increases according to the area to be covered i.e. $1600- $1900. It can also increase if the area to be covered is in acres. It can go up to $12000. This kind of booster will not be installed for one person but with the contribution of all.
