I am pretty sure that you know why you are experiencing dropped and unclear phone calls. However, are you aware of the product that could solve this problem of yours? Here is a description of how you can improve cell coverage. Let me be crystal clear here, you can enjoy calls with better clarity by installing a cell phone repeater. If you are still interested in knowing more about this then continue reading.

What Is A Cell Phone Repeater?

This device is popularly known as a cellular repeater, or a cell signal booster or even simply amplifier. It essentially is a device that is used by the customers in pursuit of excellent network coverage indoors. It is typically made of three components:

  • Donor antenna
  • Amplifier
  • Rebroadcast antennas

Often this type of device is found installed indoors. The primary goal of installing it indoors is to negate the attenuations caused by the building materials and thereby attract signals from outside. The donor antenna attracts the available RF signals from the nearest cell towers. This donor antenna then transmits this signal to the amplifiers using a coaxial cable. After the process of amplification is done, it then retransmits the stronger signals to the rebroadcast antennas.

How Does A Cell Phone Repeater Work?

The main component of this kind of repeater is the amplifier device which is essentially a bi-directional signal booster. The specialty of a bi-directional amplifier is that it can enhance signals in the downlink as well as uplink directions. This enables the connected devices to receive and send data signals to the nearest cell tower locations.

There are three main components to this bi-directional amplifier and they are:

  • Power splitters – to split the available RF signals into various bands
  • Duplexer filters – to segregate downlink blocks from the uplink blocks within bands.
  • Amplifiers – to enhance the available signals

What Are The Mandates For Its Smooth Operation?

The primary requirement that essentially must be met to ensure the smooth operation of a cell phone repeater is the availability of adequate donor RF signals. A majority of the RF boosters add noise to the donor signal and this is called a noise figure. On an average, the noise figure lies between 6dB and 8dB. For the cell phone repeater to perform optimally, the signal to noise ratio must be higher than the noise figure. Therefore, if there is not an adequate donor RF signal, the users will not be able to enjoy boosted signals. Furthermore, there must be isolation between the donor and the rebroadcast antennas.
