What Are Cell Phone Signal Boosters And How Do They Work?

Cell Phone Repeater Reception Booster Types

Analog Signal Repeaters

Most of the amplifiers of today are analog types. They amplify every type of mobile phone carrier frequency with the use of traditional technology. There are also wide-band or broadband amplifiers, that are typically sold with an outdoor-antenna cable kit. Installation is required with this option.

In some cases, the analog signal amplifiers are called BDAs or Bi-Directional amplifiers or repeaters. These are the signal boosters that localities require under their laws to permit first-responders to stay in constant contact around various facilities and areas for the purposes of catering to emergency situations. Bi-directional amplifiers are used for both two-way radio and cellular phone use.

Smart Signal Boosters

This generally defines the latest version of the “wireless” cell phone signal boosters that use powerful all-digital baseband processors which clean the coverage before rebroadcasting. Smart-reception amplifiers include over 100 dB gains when compared to the analog counterparts that only include 63-70 dB gains. They may cost a bit more than the analog types but include impressive features such as plug-and-play, and an internal-donor antenna inside the booster box, and there is also no need for an outdoor antenna.

Why Is Your Cellphone Signal Weak?

When testing cellular coverage in a location filled with 100-feet white pine and deep wood red trees in New York, the signal booster managed to overcome several obstacles situated in many rural areas spread across the U.S. The outcome involved a reliable reception for cell phones in the homes in these areas. Voice and data receptions for the different carriers were also enhanced.

Distance Between Your Home/Vehicle And The Cellular Tower

One of the main reasons why cellphone reception drops is when you are far away from the closest cellular tower. The closer you get to one of these towers, the more the signal increases.

Outside Interferences

There is also external interference that can affect cellular coverage. In most cases, the cellular signals are typically radio waves that encounter many obstructions since they cover a long distance to reach cellular phones. Effective transmission for these waves will require an unobstructed and clear line directly to the carrier tower. External interruptions such as skyscrapers, trees, tall buildings, mountains, billboards, hills, and weather elements such as rain, thunderstorms, and snow often weaken or decrease the reception.

Inside Interferences

Internal interferences are another factor that weakens reception. This can include things such as building materials such as thick concrete, thick layers of bricks, radiant barriers, and metal and glass, electronic and magnetic clutter. There are also conductive materials in buildings that can weaken or block the incoming coverage. The external signal might be strong, and even near to the cellular tower, but when it comes to the interior of your home or office building the signal might be weak or blocked caused by various internal interferences.

Certification Of Repeaters

Today, in both the United States and Canada, every cellphone signal booster repeater or a mobile signal repeater must be certified. Certification from both these federal governments will mean that these amplifiers are working as indicated or required. This means that they will extend the overall range of cell phones or deal with decreased cellular coverage. The FCC or Federal Communication Commission is the U.S. body that mandates the testing and certification of cellular boosters on the markets. In Canada, the IC or Industry Canada holds the responsibility to make sure this also happens.
