Four Points to Consider while Choosing a Cell Phone Booster

 In Technology

Cell phone boosters also known as cell phone repeaters were primarily developed to address factors that lead to poor cell phone reception. They work by improving signal strength by signal amplification and bypassing any obstruction to provide stronger signals indoor.

The system has three working components: an external antenna, a signal boosting amplifier and an internal antenna. The three units are linked to each other by a physical cable connection. Few manufacturing companies have an integrated amplifier and internal antenna. First, the signal transmitted is received by the external antenna, which then transmits the same through an amplifier, from which it is broadcasted through an internal antenna. Two-way stronger communication is ensured by reversing the signal reception: the signal is first transmitted through your phone, amplified and broadcasted back to the tower.

There are many cell phone repeaters that are available in the market. While the basic working principle remains constant, there are four important considerations before you zero in on a specific model.

  1. Potential of a signal booster: For optimal booster functioning, there must exist a stable signal which can be received and amplified. Repeaters are not capable of producing signal; they can only amplify and transmit an available signal. The booster will not work if you place the external antenna in an area devoid of any signals.
  2. Signal strength: The strength of the signal transmitted through the amplifier is directly proportional to the area covered inside your office, home or vehicle. A strong signal outside translates to a similar area coverage as advertised in the product description. If the signal is weak outside, to reach the preferred coverage range, opt for a stronger system. The bars on your phone also help in gauging the strength of the signal and assist in the placement of the external antenna.
  3. Coverage area: Coverage is specified by the square footage that is covered under optimal conditions. An optimal condition is defined as having strong external signal with ideal placement of internal antenna with absence of any obstacles that could hinder the signal transmission. Thus, while choosing a signal booster, choose a stronger one than the requirement.
  4. Carrier frequency: Each carrier transmits within a specified frequency range. If your booster is above or beyond the carrier frequency range, the booster will not work. Most carriers transmit two frequencies for 2G and 3G network 850 MHz (cellular) and 1900MHZ (PCS). If the booster is specified as “dual-band” amplifiers, they can boost both frequencies.
