Most often, in suburban and urban areas, we do not experience cell phone connectivity issues. This is because these places are properly covered by cellular networks. However, when you get out of town into rural locations, hilly locations, highways, etc., the cell phone signals usually become weak. As a result, the call quality is affected, data speeds are reduced, leads to dropped calls, etc. The best way to overcome this issue is to use a cellular signal booster. In this article, we will best attempt to answer what a signal booster can and cannot do.
The Change In Cell Phone Design
In the earlier days of cell phones, the cellular network coverage was not widely established as it is now. Because of this, they needed external antennas for better connectivity. But now, with better coverage and digital filtering of signals by receivers, signal transmission became less efficient. So, modern cell phones struggle to stay connected in areas with poor network coverage, and this is also exacerbated by their internal antenna(s). This can be rectified by using a cellular signal booster that functions like the scientifically designed external antennas of older cellular phones.
Cell Service Booster
A cell service booster receives weak cellular signals, amplifies it, and retransmits the signals to your phone. Besides, the reception of cellular signals depends on the efficiency of the antenna used in this device. For example, the efficiency rating of the antenna used in your phone usually ranges between -2 to -10 dBi. But the efficiency rating of antennas used in normal signal boosters ranges between +1.1 and +2.0 dBi. Keep in mind that higher numbers are better than lower numbers. Also, an increase in 3 dBi doubles the transmission power, and a decrease in 3 dBi decreases it by half. Finally, a typical signal booster gives a minimum of +3 dBi increase.
The donor antenna of a cellular signal booster is placed outside the building or vehicle. Due to this, it has a better line of sight with the cellular tower. This brings tangible improvement in connectivity, as it helps to bypass the objects and materials that block or reduces the strength of cellular signals reaching your cell phone. However, if the cellular signal is too weak, i.e. the tower is extremely far away, there will be more noise in the input signal to the device.
The Range Of Cell Service Booster
The coverage provided by the signal booster depends on the signal from the cellular tower. If there is any obstacle in the line of sight between the tower and the donor antenna, then the booster won’t make much difference. Otherwise, it will give a significantly good coverage area.
These are the important points that you must remember when using a cellular signal booster for better cellular connectivity.
