A mobile signal booster is a simple device that comprises of 3 parts: a donor antenna, an internal antenna, and an amplifier. These parts work together to give improved cellular reception to user devices. The external or donor antenna works as a signal receiver having maximum sensitivity and power. The main purpose of using a 4G LTE booster is to pick up the weak signal around your house, workplace building, or vehicle, and strengthen it.
After it is amplified, the signal is emitted through the internal antenna to the area of weak reception. Some signal boosting systems come with a reception amplifier in the indoor antenna, besides the external antenna and main amplifier.
There are some add-ons for the three main booster system components, and these include a splitter, couplers, an attenuator, and a surge protector. The fourth component is made to safeguard the booster system from surges in amperage, which occurs because of lightning. Therefore, some manufacturers also refer it to as lightning surge protector. This kind of product is also available for distributed antenna systems and Wi-Fi boosters.
On the other hand, couplers are utilized to drive the booster signal between multiple internal antennae. Put another way, these things and splitters enable distributing the signal in the desired way throughout the area of use.
What Causes A Requirement For The Booster
Boosters are of use where the signal is weak. Certain physical and immaterial things affect the signal strength, and these include trees, metal, concrete, and distance between the device and a cellular tower. The distance has no physical form, so it is an immaterial thing in this context.
Cell signal strengths are expressed in decibels per milliwatt. Also known as dBM, this unit is utilized to work out the receiving and sending power of cellular signals. The signal strength is calculated on the basis of the magnitude of the electric field at the intersection point. This strength of the signal is also described as field strength. When you talk on the phone, your voice is turned into signals, and these are then transmitted in the form of radio waves. After recpetion, the other caller’s mobile device converts the signals into voice.
The use of a 4G signal booster for home can help improve the voice quality. It works on every carrier network, including 4G LTE, and for all types of mobile devices.
