How signal booster Works?
Mobile repeaters are designed to fulfill the idea of one and main principle: to fill the areas with the
weak or bad signal and to amplify these low signals in order to provide you with the
communication suitable for you.
The signal booster makes the signal stronger in places with poor signal such as:
1) Underground areas: basements, parking lots, tunnels;
2) Other places where cellular signal is shielded by metal or concrete walls:
offices, supermarkets, cinemas, hotels;
3) Places distant from the BTS like private houses.
Steps that describe the work of signal booster .
1) The outside antenna receives the signal from the nearest mobile base station.
2) The outside antenna sends the received signal through the coax cable to
the installed Repeater.
3) The Repeater accepts the low signal and improves it.
4) The improved signal goes to the inside antenna through the connection coax cable.
5) The inside antenna send the improved good signal to your mobile phone.
Installation Approaches for signal booster :
1) Fix up outdoor antenna reception on housetop
or outside the window and point it to the signal tower.
2) Connect outdoor antenna to “Outdoor” port in repeater machine through cable.
3) Connect indoor antenna(s) to “Indoor” port in repeater machine through cable also.
4) Plug power adaptor into AC power socket and finish installation.
The signal booster Guide
A cell phone repeater (also known as a cell phone signal booster) is a system which takes a cell phone signal from one area where the signal is good, and repeats (or amplifies) it to an area where the signal is not good or nonexistent. A cell phone repeater has three main parts, an outside antenna that receives the initial signal, an amplifier that boosts the signal, and an inside antenna that broadcasts the boosted signal to the inside are that needs it. All three components are connected together with high quality cable.
A cell phone repeater is able to bring a weak signal inside and amplify it significantly, but it does require a stable signal in the area where the external antenna is placed in order to work. Ideally, this is a strong signal that it can repeat, but even a weak signal can be adequately amplified when combined with a strong amplifier. A cell phone repeater will not work for areas which have no signal or have a signal which is unstable and repeatedly cuts out. If you are able to place the external antenna in a location which has signal, then a cell phone repeater should work for you.
There are different types of cell phone repeaters which vary in strength and can be configured with different types of antennas in order to solve your situation. We'll cover the most popular types of cell phone repeaters here.
Cell phone repeaters for homes and offices, or really any building, utilize a powerful amplifier and antennas to broadcast the boosted signal to a large indoor area. They range in power from entry level boosters that are for a single room, up to the most powerful boosters that can cover tens of thousands of square feet. Some of these boosters can also employ multiple inside antennas to provide the necessary coverage to the indoor area the requites better coverage. You can browse the home and office or large building signal booster kits, or use our product selector tool below to determine the right booster kit for you.
Vehicle cell phone repeaters come in two kinds. The first kind is a cradle cell phone repeater which combines the amplifier and internal antenna into once device and can only be used by one cell phone at a time.
The other type of vehicle cell phone repeater is able to broadcast boosted signal to the inside of the vehicle and can be used by multiple phones and data cards at the same time. This is the ideal cell phone repeater kit for long distance travelers, families, carpools, and more.
