Booster Guide Lifestyle

Curious about cell phone signal boosters? In this comprehensive guide, you’ll get answers to the most common questions about cell signal boosters, the benefits of having a cell phone booster, and the different types of cell phone boosters currently available for your home and vehicle. 

What is a cell phone signal booster?

A cell phone signal booster (also known as a cell signal booster) is just what it sounds like; a device that boosts weak cellular signals for use by cell phones, smartphones, tablets, hotspots, and other cellular-connected devices. By amplifying the existing cell signal, cell phone boosters help:

  • Reduce dropped calls
  • Improve voice quality
  • Increase data speeds

Regardless of which U.S. carrier network you use, everyone has experienced weak cell signal.

Types of cell phone signal boosters

Cell phone signal boosters fall into two main categories:

Home cell signal boosters are designed to improve indoor signal conditions within spaces ranging from one room to an entire home. Most home boosters support multiple users and multiple devices simultaneously and across multiple carrier networks.

Vehicle cell signal boosters (or mobile signal boosters) are designed to enhance cell signal within a car, truck, van, or SUV. We also have models specially designed for RVs, towable trailers, semi-trucks, or fleet vehicles. Most weBoost vehicle boosters support multiple users and devices, while some like our Drive Sleek products, boost signal for only one cell phone.

For commercial and industrial buildings, we recommend our WilsonPro brand of products.

How outside signal strength influences booster performance

The stronger the outside signal strength, the more effective a cell phone signal booster will be at amplifying the signal strength indoors. Remember, the signal bars on your phone only provide a relative measure of the existing signal strength in your area. It’s possible for one phone to show full signal bars while another phone shows two signal bars while receiving the same signal from the nearby cell tower.

What makes cell signal unreliable?

Although several factors can contribute to the quality of cell phone reception, below are some primary causes of unreliable cell signal.

  • Distance - the farther away you are from the cell tower, the weaker the signal is. 
  • Terrain - Hills, mountains, trees, foliage, rocks, and other terrain features between you and nearby cell towers can prevent cell signal.
  • Buildings - Because cell signals can’t easily pass through metal, concrete, or energy-efficient windows, buildings are the main blockers of cell signal in many places.
  • Vehicles - Metal and safety glass, the materials making up the outer shell of most vehicles, do an excellent job of blocking cell signals.

Will a cell phone signal booster work for me?

As long as there is an available signal outside your home or vehicle, then the booster can amplify it inside your space to give you improved talk, text, data, and more.

We offer boosters that vary depending on your cell coverage needs. For example, If you only need a booster for a single phone in your car, the best cell signal booster for you will be different from someone whose situation might require a multi-user booster. Likewise, cell signal boosters can vary depending on the size of your home. By checking the existing signal strength inside your home (as well as outside), you can better determine which type of booster will work best for you. Since signal bars only provide a relative measure of signal strength, check out our blog on testing signal strength using free apps and online resources.

How much does a cell phone booster cost?

The cost of a cell signal booster can range from $199.99 to $1199.99. The cost depends on a number of factors, including the overall performance of the booster kit, installation, the number of users or devices the booster can support, and how many carrier networks are compatible with the booster.

As a general rule:

  • The more powerful the booster is, the higher the price.
  • A booster that provides more coverage area costs more.
  • One-device vehicle boosters cost less than a booster that supports multiple users and devices.
  • Boosters that only work with specific carriers cost less.

weBoost cell signal boosters are a one-time investment with no ongoing fees.

Do I need an internet connection to use a cell phone signal booster?

No, an internet connection is not required. A cell phone booster works by amplifying the available cell signal in your vehicle or home. It will improve cellular coverage for tasks like phone calls and text messaging. Cell coverage is more reliable and secure than WiFi. Some users may use cellular coverage due to its faster data speeds, uninterrupted streaming, and improved hotspot capabilities.

Do cell phone boosters interfere with WiFi?

Because they operate at different frequencies, cell phone signal boosters will not interfere with WiFi. However, it is still recommended to mount the inside antenna for a cell phone signal booster at least 12 inches away from a WiFi router to avoid any interference.
