There are millions of homes around the globe where people don’t get a strong cell signal. Despite having a cell tower nearby and a strong signal just outdoors, your home or office can sometimes be a no-reception zone. There is a workaround for this kind of problem: a cellular repeater. Such a device takes in the weak signal, amplifies it, and rebroadcasts it in the immediate vicinity.
How Cell Repeaters Function
Cell repeaters are much like actual cell towers, in that they broadcast the waves which carry cellular data. The main difference though, is that coverage cannot be created out of nothing. The repeater has to be able to grab the signal coming in from the carrier’s tower.
For that, this device has an exterior antenna as one of the components. This antenna picks up the signal coming in from outdoors, no matter how weak it is. Then there is the amplifier component, which is responsible for boosting the signal and then sending it on to the internal antenna. The latter rebroadcasts the signal within the immediate vicinity, say inside the house or the vehicle, and you phone is able to pick this up fairly easily. This signal is a lot stronger than the regular signal, so you don’t have to worry about dropped calls or slow loading speeds.
Where To Place One?
Cellular repeaters can work potentially anywhere, provided there is a signal from a tower. Even though the building or home may have poor coverage on the indoors, there is usually bound to be sufficient signal one at least one side. The exterior antenna is meant to be set up in this side, so that the strongest possible signal can be caught and used. It is popular practice to use repeaters in basements, buildings that have metal walls, and the interior areas of large buildings. Even in locations where the nearest cell tower is placed on the opposite side of an obstacle, such as a mountain for instance, repeaters can be sued to amplify coverage.
There are many repeaters in the market that are carrier-specific, while others are able to work with all carriers at the same time. The former are better when it comes to signal strength and security. There are also repeaters which can provide both 2G and 3G coverage with signals from all carriers. There is also the option of setting up multiple repeaters.
