How do Vehicle Signal Boosters Work?

Similar to home signal boosters, vehicle cell boosters capture the existing outside signal and amplify it within a confined space, in this case your car, truck or RV.

Typically, car cell phone boosters have three parts:

  • Outdoor antenna captures the signal from the cell tower (also known as a “donor antenna”)
  • Signal Booster amplifies the signal from the outside antenna
  • Inside antenna rebroadcasts the boosted signal

Boosters act like a cell phone signal range extender, improving coverage area and strengthening transmission and data signal.

Do All boosters work for All Vehicles?

You will want to choose a signal booster based on your vehicle, so making sure you get the right one for you depends on the vehicle you plan on boosting your signal in.

Are Vehicle cell phone boosters carrier-specific?

Vehicle cell signal boosters are rarely carrier-specific. In fact, none of the vehicle boosters on the SIMETRY store are carrier-specific. That means you can use the boosters sold on the SIMETRY store to boost AT&T, Verizon, T-Mobile and most other network signals.

Some mobile cell phone boosters are designed to enhance just one cell network signal at a time, so if you are attempting to boost multiple devices with varying carriers, you will need to choose a booster with multi-carrier capabilities.

What Specs to Consider When Choosing a Vehicle Signal Booster?

In regards to vehicle cell signal boosters, you will want to consider uplink output power (measured in dBm), or the strength of the signal leaving your device towards the cell tower.

Gain (measured in dB) is also an important variant amongst boosters – the maximum gain from multi-carrier vehicle boosters is 50 dB. Maximum gain for single-carrier vehicle boosters is 65 dB.

Downlink output power (measured in dBm) measures the maximum signal the booster can transmit inside the vehicle. You will want more dBm for more area, or larger vehicles such as RVs.

Choosing the best cell booster for your vehicle

Pick the best booster for your vehicle based on two important factors:

  • What type of vehicle you have
  • Number of devices you want to boost

We have handpicked the best vehicle signal boosters for each use case below. These boosters are manufactured by the best brands in the business. Each booster is linked to its own product page on the SIMETRY store where you can purchase if desired.

Every booster we sell is FCC approved and designed and assembled in the USA. Additionally, these boosters enhance cell signal from all of the major carriers.
