All About Cell Phone Signal Booster

Mobile phone towers are not always able to transmit strong signals for cell phones to catch. Often, when a phone is located far away from the nearest tower, the signal becomes weak. It’s in such cases that a cell phone signal booster becomes very useful. Let’s learn something about mobile phone signal boosters.

Principle

A mobile phone signal booster works via picking up weak signals that are transmitted by the towers of the service provider and amplifies the signal for the mobile phones’ receiver antennae for improving its performance. This usually happens when the energy emitted around the mobile phone handset is captured by the booster and funneled into the signal, which in turn, improves the reception. Mobile phone signal boosters are mostly linked to broadcast towers and they rebroadcast the phone’s incoming signal within a designated area only. In fact, with a state-of-the-art booster, you can make use of the same gadget for numerous phones.

Design

There are innumerable products available in the markets that are vended as cheap cell phone signal boosters. Most are tiny devices that can be directly attached behind the battery or externally for enhancing the signal captured and produced by the mobile phone handset. The main principle behind these boosters is to augment the surface and for receiving and sending messages almost similar to that of a satellite dish antennae. They are lightweight and thin and hence they can snug into any cell phone sans adding any weight or bulk. There are several cheap cell phone signal boosters that come as stickers and can be placed on the handset itself. Their effectiveness, however, hasn’t been proven and they are controversial as well.

The directional antenna is a component of the mobile phone signal booster. It is usually oriented toward the direction from where the signal comes, such as the cell phone tower, for acquiring the strongest possible reception. The thumb rule for a directional antenna is that the bigger the antenna, the better is the signal. Even small and cheap cell phone antennas are often capable of receiving higher signal strengths compared to the more expensive internal antennas.

Rebroadcast

Once the directional antennae catches signal, the internal booster rebroadcasts it within the radius of a localized area. This distributes the quality of the signal across all directions, subject to the fact that there aren’t any obstacles. It follows the principle that a mobile phone works best whenever the antennae is aligned to the signal booster antenna in the cell phone. The internal antenna of the handset helps to increase the reception quality of the transmission.
