A cell phone repeater (also known as a cellular repeater, cell phone signal booster, or cellular amplifier) is a device used to improve cellular signal in an indoor or outdoor setting. Most common types of cell phone repeater work in confined, indoor areas such as buildings or vehicles. They are usually made of three primary components:

A cell phone repeater is used to bring signal from outdoors inside a structure or vehicle, bypassing building material that harms radio frequency (RF) waves. These can be scaled from low-power units covering the inside of a car to large active distributed antenna systems (DAS) covering large stadiums.

The outdoor antenna(s) is connected via coaxial cable and connectors to a repeater (or amplifier) unit, which amplifies the signal. The rebroadcast antenna(s) then retransmit this amplified signal locally. These three components are installed in order to maximize coverage indoors. These components have numerous arrangements based on the power of the amplifier and the desired result. More powerful systems can have numerous donor and rebroadcast antennas depending on the need of the building they are installed in.

The most important part of a cell phone repeater is the bi-directional amplifier. This is the centerpiece of every system, and what provides the increased reception you are after. There are several types of amplifiers, each of which function slightly differently:

The weBoost Home MultiRoom is the bestselling do-it-yourself cellular repeater. It is the signal repeater that works for most people. It can cover up to 5,000 square feet if your outside signal is perfect. Most people will probably see a coverage area of 2,000 to 3,000 sq ft. If you live in a rural area with very weak outdoor signal, expect much less coverage. This is the weakest cell repeater you should buy if you have bad signal outdoors.

The cell phone repeaters we recommended above are multi-carrier systems. This means they are also compatible with AT&T, Verizon, T-Mobile, US Cellular, and other major and local carriers. They cover 5G, 4G, and LTE signals.

Wilson Amplifiers is the leading provider of Wilson Electronics cellular signal repeaters. Cell phone boosters amplify 5G, 4G, LTE, and more for any phone with any carrier for home, office, or vehicle.

A WiFi repeater or extender is used to extend the coverage area of your WiFi network. It works by receiving your existing WiFi signal, amplifying it and then transmitting the boosted signal. With a WiFi repeater you can effectively double the coverage area of your WiFi network - reaching far corners of your home or office, different floors, or even extend coverage to your yard.

WiFi Repeaters are very easy to install. All you have to do is place the repeater in a location that can receive your existing WiFi network, and then attach the power supply. You can then log into the WiFi repeater via your computer, and input the login details and password of your existing WiFi network, to allow the WiFi repeater to connect and extend.

Got a tricky situation like a pool house in your garden? No problem! There are weatherproof WiFi repeaters like the Hawking Outdoor Smart WiFi Repeater that can be placed outside, boosting signal throughout your property. This kit is very flexible and can be moved easily. For example, if you are RVing and the campsite has weak WiFi signal, this repeater can be fixed to the roof of your RV to boost the signal inside.

Only if you go entirely out of range of the first network. A WiFi repeater creates a second network. If your first network is not available, your device will connect to the second. But in some parts of your house, your device will be able to detect both networks at the same time. This means that if you wish to change from the original network to the boosted network you will have to disconnect and then reconnect.

All WiFi repeaters have some speed loss, but some are much worse than others. WiFi repeaters work by receiving wireless signal and rebroadcasting it, but single band repeaters have to receive, then retransmit each packet of data using the same radio on the same channel. This can cost single band repeaters 50% of their bandwidth.

Dual band repeaters get around this by connecting to the router on one band and outputting a WiFi signal on the other. The Netgear Nighthawk AC1900 Dual Band WiFi extender uses FastLane technology to improve performance using both WiFi bands. A fast processor also really helps (the Nighthawk has a Dual core 1GHz processor) by enabling maximum WiFi throughput.

One final feature that helps reduce speed loss is dual radios. If the device has dual radios, it can speak to the main router on lower channels, and then rebroadcast on higher channels. The Hawking Dual Radio Smart Repeater (HW2R1) uses two Wi-Fi radios. One Wi-Fi radio receives the signal and the other radio rebroadcasts the boosted signal. This clever design allows the boosted signal to utilize a different WiFi channel, which greatly increases performance compared to single radio repeaters. The Smart Repeater Pro also has a very powerful high gain antenna that can pick up even very weak WiFi signals, and it rebroadcasts that signal on two powerful 3dBi omni-directional antennas.

To qualify as licence-exempt, a repeater must only boost the signal of one network at a time. You can buy wideband repeaters that cover multiple networks, but these are illegal to use in the UK without a licence, as that they can impact every network in the area at once.

With a static indoor repeater, the uplink antenna also has to be located inside a building, rather than outside, to minimise interference. Similarly, a low-gain mobile repeater must only assist coverage inside a road vehicle, not inside a static caravan or boat.

If your business is located in an area where AT&T provides cellular service, your indoor signal strength is two bars or less, and you are able to comply with all of the transport requirements outlined in the AT&T Cell Booster Pro User - Technical Requirements Guide, AT&T Cell Booster Pro may be the perfect solution for you. An AT&T Cell Booster Pro is designed for up to 64 simultaneous sessions and provides in-building coverage of up to 15,000 square feet per device, depending on building layout and construction. Up to 3 Cell Booster Pros can be used at a street address, bringing the total space to 45,000 square feet for up to 192 simultaneous sessions. An AT&T Cell Booster Pro may not be used as an RF source for a DAS.

We've put together a brief summary of the basics of an in-building cellular signal repeater system in nontechnical terms. We've also included a short video. We explain the components and factors to consider when selecting each part of a system. Remember, much of the following are generalizations and simplifications but enough information to select parts for a simple system.

A cellular repeater system captures the signal using the Outside Antenna. The signal transfers to the Cellular Repeater Amplifier through a cable. The signal is then amplified and rebroadcast through the Inside antenna. Sending a cellular signal works in reverse. The inside antenna captures the signal, and it travels to the amplifier. The signal is amplified and sent back to the tower via the outside antenna.

Omni-directional building antennas are best for capturing a signal from several towers in the area. For instance, use an omni-directional antenna if your repeater system installation goal is to obtain a signal from several service providers (AT&T, Sprint, Verizon, T-Mobile for example). And, each service providers tower is in different directions, an omni-directional antenna is best.

The cellular amplifier is the heart of the repeater system. It takes the outside signal, amplifies it then rebroadcasts the signal through the system's inside antenna. A few key factors on amplifiers are:

Amplifier Gain is used as a relative measure of improved cellular coverage area inside. The higher the gain, the more area is typically covered. If one amplifier has 3db gain more than another amplifier, the amplifier with 3db more gain will cover roughly twice the area. So why don't you just purchase the booster with the highest gain? Cost and antenna separation requirements. It's important to note that the higher the gain, the more separation distance required between the inside and outside antenna (Read more in "Oscillation Control" below).

The output power of an amplifier can be used as a relative measure of power when communicating with your service provider's tower. Higher power is not necessarily better. The power required is just enough to get the necessary coverage inside and not negatively affect a service provider's tower and knock other customers off (read "Oscillation Control" below). The maximum power allowed with the US is 3 watts. A good cellular amplifier will have oscillation control and will monitor the power of the amplifier to and from a tower.

The cell amplifier used must match the frequency used by your service provider. Most US cellular service providers use wireless networks that are within 800MHz or 1900MHz frequency ranges. For 4G, carriers may use different frequencies. For example, AT&T and Verizon may use 700MHz for their 4G LTE service. T-Mobile may use 1700/2100MHz for their 4G.

Signal oscillation occurs when the inside antenna signal contacts the outside antenna. Instead of the outside antenna getting a signal a service providers tower, the two repeater system antennas communicate with each other.
