How Boosters Work

At Walco, our customers are constantly battling to obtain sufficient signal in remote locations. As discussed in our previous post, Telus is working to increase towers in remote locations to boost signal. However, many areas still suffer from this problem. This is part of why cellular boosters are a common requirement in Canada. However, there is a limited understanding of what these devices can do. People purchasing a booster may be disappointed with the results due to this lack of understanding.

Here are a few key things to know about boosters:

1)      Work with what’s available

Boosters are aptly named. They boost signal. If there is no signal, the booster will not work. Thus, it is key to identify a location in your vicinity that has some level of signal consistently. If this cannot be located, a booster will not offer a solution to your problem.

The level of signal available dictates how wide a coverage area will be created by the booster. If 5 bars can be located, the range of the booster will be much greater than if there are only 2 bars. It also dictates how powerful a booster may be required.

A booster has a set amount of amplification power, rated in decibels. In theory, an increase of 3 dB amounts to double power. However, many factors affect signal and amplification. Nevertheless, it is important to know the level of signal you are working with prior to purchasing a booster.

2)      Antennas, Antennas, Antennas

Antennas are required to transmit signal. Therefore, it is not surprising that antennas are required for boosters. Actually, two antennas are required, one inside and one outside.

For outside antennas, there are two main options. First, is an omnidirectional antenna, which receives and transmits in all directions. This is best suited when receiving some signal from multiple towers.  Second, is a ‘yagi’ or directional antenna. This antenna does not cover as much area; however, it receives and transmits for a much greater distance in the chosen direction. This is best suited when receiving signal from one tower.

Inside antennas broadcast the signal inside the building.

Another feature of antennas to keep in mind is minimum separation. For 50 dB in building boosters, a separation of at least 40 feet must be maintained. This is to prevent feedback. The booster itself does not need to be separated from the antennas, just the antennas themselves.

3)      Other Factors

The amount of signal you obtain from a booster is dependent on many factors including frequency, strength of signal outside, and building construction. Factors relating to building construction include the number of walls, and the construction materials used. This is an important consideration when determining where to place a booster or antenna.

4) Summary

Increasing signal can be a complicated affair. At Walco, we have a great deal of experience assisting people with determining the best product for their needs. Drop by or give us a call if you have any questions about Wilson or Smoothtalker boosters and how they can help.
