Booster Basics for Boosting Cell Phone Signals

What is a Cell Phone Signal Booster

Cell phone signal boosters work by capturing a signal outside or nearby to your building and repeating that signal inside of your home, apartment, office, commercial space, car, truck, or RV. As a best practice, if you can make a phone call at any single location outside of your building, a cell phone signal booster will work for you. Even if you cannot, we can often customize your booster kit in such a way that it will. Boosters have no recurring fees, support all carriers, can be simple to install, and are a great way to get rid of dropped calls and bad cell reception for spaces between 10 and 100,000 sq ft.

  • Eliminates Dropped Calls
  • Improves Cellular Reception
  • Crystal Clear Call Quality
  • Improves Data Speeds
  • Support Multiple Users
  • No Recurring Fees
  • Support for All Carriers
  • Expands Coverage Area
  • Extends Cell Phone Battery Life

Why You Have Bad Reception & Dropped Calls

Bad reception and dropped calls are the result of different factors working both independently and together. These factors include distance from a cellular tower, user capacity for a cellular tower, and impediments between you and the tower such as geographic features (hills, mountains, rocks), organic features (trees, leaves, snow-pile), weather conditions (rain, snowfall, wind, dust), manmade structures (buildings, walls, fences), and conductive materials (copper, aluminum, salt water, and anything else that can conduct electricity). All of these can have a negative impact on the quality of your cell signal but, in most cases, a signal booster will be able to overcome these obstacles.

How Does a Cell Signal Booster Work?

HOME
COMMERCIAL
CAR & RV

A cell phone signal booster captures a nearby cellular signal, amplifies it, and broadcasts that signal in the space that needs a better cell phone signal. Signal booster kits work for small and large homes, offices, apartments, commercial buildings, and even cars, trucks, and RVs.

Regardless of the space, the specific components of a cell phone booster include:

  1. Outside Antenna - Installs on the exterior of your building in the location that receives the strongest signal from a nearby cell tower. This captures the strong signal outside of the building and pulls it into the building.
  2. Signal Booster - Receives the signal from the outside antenna and amplifies the signal strength before sending the improved cellular signal to the indoor antenna(s).
  3. Indoor Antenna(s) - These are installed inside of the building to distribute the amplified signal throughout your building or vehicle. Some buildings may require multiple indoor antennas and/or multiple boosters.
  4. Cables - Connects the outdoor antenna with the booster and the booster with the indoor antenna.

Choosing an Outdoor Antenna

SureCall Outdoor Yagi Antenna
SureCall Outdoor Omni Directional Antenna

There are a few key considerations that will drive your decision to buy a kit with a directional antenna or omni-directional outdoor antenna. The top on the list include the quality of your signal outside, the number of carriers that you need to boost, and whether the space is in-motion, like an RV, car or truck, or stationary, like a house, apartment, or office.

Choosing an Indoor Antenna

SureCall Indoor Panel Antenna
SureCall Indoor Dome Antenna
SureCall Indoor Whip Antenna

Generally, there are three primary indoor antennas: panel antennas, dome antennas, and whip antennas. SureCall boosters are kitted with indoor antennas that will provide the best coverage for that booster but, occasionally, some kit customization may be needed.

Choosing a Signal Amplifier for Car, Truck, or RV

Signal amplifier options for a car, truck, or RV are small and easy to install. The ideal booster for a single driver in a sedan will not be the same as the perfect choice for the family of four that is road-tripping in their SUV or RV. The SureCall Fusion2Go 3.0 is available as a kit for vehicle or RV and is the industry’s most powerful signal booster for cars. The SureCall FusionTrek is a single-user signal booster that has no outside antenna and is the easiest-to-install booster on the market. The Fusion2Go 3.0 and FusionTrek both boost 2G, 3G, and 4G LTE signals for AT&T, Verizon, T-Mobile, Sprint, Telus, Rogers and any other North American carriers and phones.

Choosing a Signal Amplifier for a Small Home or Office

A signal booster for a small apartment, home, or office can help you avoid having to run outside or stand by a window to answer calls or send texts. The award-winning SureCall Flare is an all-carrier voice and 4G LTE signal booster with integrated indoor antenna that supports spaces like homes or cabins up to 2,500 sq ft. The SureCall EZ 4G boosts 4G voice and data in spaces up to 2,000 sq ft without the need for an external antenna. The Fusion4Home similarly amplifies 4G signal in a space of up to 4,000 sq ft.

Choosing a Signal Amplifier for a Large Home or Office

Maintaining talk and text service in a large home or office can be challenging. Everything from construction materials to sheer size can turn parts of your space into dead zones. In most cases, a signal booster can deliver a better voice, text, and data experience throughout your office. The SureCall Fusion5s boosts voice, text, and 4G LTE data signals for buildings of up to 6,000 sq ft. The FlexPro is a more basic and cost-effective signal booster, also for spaces of up to 6,000 sq ft. For big jobs, choose the mighty Fusion5X 2.0, which is the industry’s most powerful signal booster in its class for amplifying 3G and 4G LTE signals up to 20,000 sq ft.

Choosing a Commercial Booster for Large Buildings

Commercial spaces present their own unique challenges for cell phone reception. The size of the building, distance from the cell towers, and construction materials used can turn a hot cellular spot into a dead zone, even in the middle of urban areas. The multi-award-winning SureCall Force5 2.0 is an easy-to-use commercial voice, text, and 4G LTE signal booster that uses four indoor antennas to support spaces up to 25,000 sq ft. Force5 2.0 systems can be expanded with multiple indoor antennas and boosters to deliver coverage to much larger spaces. The Fusion7 is the first ever all-in-one signal booster that increases cellular, Wi-Fi, and HDTV reception in large spaces of up to 20,000 sq ft. The Force7 Industrial is a perfect solution for larger installations such as schools, hotels and healthcare facilities. This powerful booster requires carrier approval and can amplify indoor cell phone, Wi-Fi, and HDTV signals for up to 20,000 sq ft of coverage and 100+ simultaneous users.

Best Signal Booster Kits for AT&T, Verizon, Sprint, T-Mobile, and All Major Carriers

Choosing the perfect signal booster can be a frustrating exercise in juggling brands, carriers, and technical information. Popular devices like femtocells are offered by cell providers and can boost specific signals. But these devices typically require monthly fees, can be a security risk, and anyone in your home or office outside of a certain carrier does not get the benefit. Choose a booster that amplifies the signal for all carriers, like SureCall's Fusion4Home, Fusion5s, or Flare. These devices are easy to install, simple to use, and increase voice, text, and 4G LTE data for all North American providers.

FAQs About Signal Boosters

What Cell Phone Bars Actually Mean

Cell phone bars are inaccurate indicators of signal strength. The reason for this is that there is no standardized scale, rather, each phone manufacturer makes up their own arbitrary algorithm. This being the case, we suggest testing your cellular strength yourself. Fast-forward to the next section to learn how!

How To Test Your Cellular Signal Strength

Websites like Cell Reception and Antenna Search or applications like OpenSignal (Android | iPhone) and Network Signal Info (Android) are easy ways to find towers and get a general reading of your cell phone signal. For larger installations we suggest using an RF Signal Meter to get a pin-point precision reading. The approach we suggest for our small- to medium-size home and office owners is field test mode.

How To Get a Better Cell Phone Signal

View our infographic for 10 free tricks to improve your cellular signal.

Will a Signal Booster Work When I Have No Cell Service?

If you have cellular service readings between -50 dB and -103 dB outside of your building, a signal booster should be able to improve your signal inside of the building. On the other hand, if your best signal reading outside of the building is between -104 dB and -150 dB and you do not have a clean line of sight to a cellular tower that is within 20-miles of your building, there is no signal booster, regardless of manufacturer, that will be able to boost your signal. Learn how to get a signal reading.

How to Use Wi-Fi Calling on Your Cell Phone

WiFi calling is a temporary workaround if you have no cellular reception but a strong Wi-Fi signal. It is important to note that without a strong internet signal, your call could drop or suffer from low-quality audio. To use Wi-Fi calling, you can download and run an application like FaceTime Audio, Skype, or Google Hangouts. You can also activate Wi-Fi calling on your iPhone by going to Settings > Cellular > Turn On: Wi-Fi Calling and for Android devices tap Settings > Activate Advanced Calling.

Is Weak Reception Draining Your Cell Phone Battery?

Yes. When you are standing next to a cell phone tower and have perfect reception your phone doesn't have to expend much energy to get great reception. On the other hand, when you have a weak cell phone signal your phone must use more energy to access a stronger signal, which draws from your cell phone battery.

Get to Know 2G, 3G, 4G LTE, & 5G Signals

What is Voice Over LTE (VoLTE)

VoLTE gives you access to more bandwidth thereby giving you higher quality audio. This allows you to place a phone call over your LTE connection rather than the older 2G and 3G networks, thus the name “voice over LTE.” Often called “true 4G” your ability to use VoLTE depends on your carrier:

Remote Signal Monitoring Software

Remote monitoring benefits business owners, managers, or installers who require continuous up-time. Whereas some booster manufacturers allow you to “remote monitor” to view the health of your system before performing on-site adjustments, SureCall Sentry™ Remote Monitoring System allows you to gauge the system's performance and manually tune the amplification and output power for each band via the Sentry web portal or applications for Android and iPhone. Remote monitoring comes standard on the Force5 2.0 booster.

Customer Example

Modern hospitals, like the Kaiser Permanente San Jose Medical Center, are becoming increasingly more dependent on cellular devices for communication with one another. When lives are at stake, dropped calls and sluggish data speeds are simply not an option. This full-service hospital is operated by 400 physicians and nearly 3,200 nurses that serve California’s Silicon Valley.

This massive and strongly-constructed hospital building made it difficult for cellular signals to penetrate through to the lower floors. Readings on floors one and two fluctuated between one and two bars and, according to hospital staff, dropped calls were a frequent concern. When teams needed to call a surgeon or doctor, send x-rays via mobile device, or receive advanced notice of an incident that would require additional staff, they needed total confidence in their cellular signal.

RepeaterStore’s RSRF Division used a Passive DAS system that included 8 SureCall Force5 signal boosters and 32 SureCall Dome Antennas to deliver reliable cellular signal to both floors of the hospitals 300,000 sq ft of coverage area.

The San Jose Kaiser Permanente hospital was so pleased with the results of the Force5 passive DAS that they added additional dome antennas to a new wing of the building in the basement. The hospital has been more than pleased with the installation and is reassured in knowing their teams are better connected and, in turn, more able to keep their patients safe and staff nimble enough to act at a moment’s notice.

Guide Summary

In order to benefit from a cell phone signal booster, you must already have cellular reception outside or nearby your building. If you are able to make a call at any point outside of your building or if there are cellular towers within 20-miles of your building, generally a signal booster will be able to help. SureCall offers lifetime support, a 3-year warranty, and a 60-day money-back guarantee to make sure your solution works well into the future.

A cellular signal booster can eliminate dropped calls, improve audio quality, boost data speeds, expand coverage area, and extend cell phone battery life. Boosters are compatible with all carriers, support multiple users simultaneously, and have no recurring fees.

Ask these questions to make the right purchase for you:

  • What is the quality of my signal outside of the building? We suggest small to medium buildings use Field Test Mode and larger buildings use an RF Signal Meter to get an accurate signal reading.
  • Which cellular carriers do I need to boost?This can have an impact on the outdoor antenna that will work best for your space. Need to boost all carriers? Most of the time we suggest an omni-directional outdoor antenna. Boosting primarily one carrier? Typically a directional (yagi) antenna should do the trick because you can point it straight at one cellular tower and the antenna will capture all signals from that tower while also receiving other signals from nearby towers just like an omni antenna. Here’s a guide to choosing the right outdoor antenna.

Signal Booster Terms You Should Know

  • Radio Frequency (RF)

    The signal wave frequency used to transmit cellular, AM and FM radio, and Wi-Fi signals.
  • Gain

    The higher the gain, measured as a positive number, the more a signal is amplified. Boosters, indoor antennas, and outdoor antennas each produce gain to create a combined, total gain value.
  • Loss

    The lower the negative number, the more loss will occur. Loss works against gain and, for example, if you have an overall 25 dB of gain and -5 dB of loss it would result in an overall gain of 22 dB. This is addressed in our complimentary design services.
  • Decibel (dB)

    The unit of measurement used to indicate cellular signal strength. Written in negative numbers, the further the number is from 0, the weaker the signal, with -50 dB being a perfect cellular signal.
  • Active DAS

    Active DAS is a distributed antenna system that uses fiber optic cables and requires the system generate a cellular signal, rather than amplifying an existing signal outside of the building.
  • Passive DAS

    Passive DAS is a distributed antenna system that uses a bi-directional amplifier (or signal booster) and does not require fiber optic cables. These systems take the signal outside of the building and amplify that signal indoors.
  • Dual In-Line Package (DIP) Switch

    DIP switches refer to the individual switches on a booster that are used to manually adjust uplink and downlink attenuation.
  • Wideband

    Also known as carrier neutral or carrier agnostic, this is the term used to define a booster, repeater, or amplifier that covers all bands of the RF spectrum. A wideband booster will support coverage for AT&T, Verizon, T-Mobile, Sprint, and all other carriers.
  • Received Signal Strength Indicator (RSSI)

    RSSI is the measure of RF signal strength that a building is receiving from an access point, like a cellular tower.
  • Donor Signal

    The signal that the booster is boosting, repeating, or amplifying. This is the signal being received from the cellular tower.
  • Broadcast Signal

    The signal that is generated by the booster and distributed to the inside of a building or vehicle.
  • RF Band

    Produced by cell towers, these sub-sections of the RF spectrum include cellular, PCS, AWS, and LTE.
  • Attenuation

    Reduction in the signal strength of a signal either through natural or forced means. You may want to attenuate a booster if a donor signal is too strong or too weak by adjusting the dip switches.
  • Oscillation

    Also called feedback, this occurs when the outdoor and indoor antennas are installed too close together. This causes the booster to rebroadcast one set of signals between the two antenna, progressively getting louder and louder until the booster enters sleep mode. Oscillation can be resolved by creating distance between the indoor and outdoor antennas.
