What is Mobile Signal Booster?

Mobile Signal booster, also called Indoor Repeater, Signal Amplifier, is a device used to increase the signal strength of your mobile phone connections to BTS, reduce dropped calls and even help you to extend your cell phone range it can increase the signal strength of your mobile by up to 100%..
A mobile phone signal (or reception) is the strength (measured in dBm) of the connection to the mobile phone with its network. Depending on various factors, such as proximity to a tower, obstructions such as buildings or trees, etc., the signal may vary. Most mobile devices use a set of bars of varying heights to display the strength of the signal where the device is located.
Mobile Signal Boosters work in the same way as the towers of cellular operator, which broadcasts signals to the subscribers. The basic difference is that a Mobile Signal booster is much smaller in size and you can get the benefit for a limited area. Mobile Signal Boosters, depending on their formation, can expand the handset’s coverage up to more than a few thousand square feet. There are even suitable Mobile Signal Boosters available that can be used inside your car. Cities all over the world are going in for High-rise buildings viz., commercial, office complexes, shopping malls & residences. All the areas in shadows of these high rise buildings and offices in basements do not receive mobile phone signal leading to bad mobile phone connectivity. To overcome this problem, Sharp Vision has introduced Mobile Signal Booster System to amplify Mobile signal level for better mobile connectivity.

What You Need To Know About Cell Phone Booster for home?
With the saturation of cell phone usage in the United States, and the increased efficiency and lower cost to use cell phones for everything from phone calls to mini computers, many people have decided to abandon their landline phones and use a mobile phone exclusively. If you have decided you want to do this, but find that your indoor reception leaves a lot to be desired, you may want to consider purchasing a cell phone booster for home.

What is a Cell Phone Booster?
Cell phone boosters, sometimes also called mobile repeaters, will increase the reception of a wireless device in a specific, localized area by employing three things—one antenna for reception, another internal rebroadcast antenna, and a signal amplifier. Some of the more advanced types can even be used with multiple cell phones at the same time, if you have more than one person at your home regularly using a mobile phone. Our Signal Boosters for Home support multiple simultaneous users 5,10,20 and more, depend on the model.
Why Would I Need a Signal Booster?
There are many different reasons that people want or need a cell phone booster for home. Some of the more common reasons include: living in a rural area, where traditional cell phone reception is weak because the cell phone towers are too far away, having specific types of construction materials that were used in your home and may interfere with or block cell phone signals (this is especially common in older buildings or older homes), or dealing with interference from signals bouncing off buildings in densely populated urban areas. In all of these cases, the use of mobile repeaters can significantly enhance the signal and increase your reception regardless of other interference in the area.
What are the Benefits of a Booster?
The most obvious benefit of using a cell phone booster for home is, of course, the intensification in your wireless signal. This will allow you to talk on your cell phone inside your home without worry about accidentally running into a “dead spot” or having the call drop unexpectedly. Another benefit of this type of technology is that it will increase the life of your cell phone battery. This is especially helpful if you are using your cell phone exclusively and have gotten rid of your landline—if your cell phone battery dies and you have to plug it in to continue using it, it doesn’t really have the convenience of a “mobile” phone anymore. Finally, in some cases, the use of a cell phone booster may even reduce the level of harmful radiation exposure from your mobile phone.
Whether it is for convenience, to save some money, or any other reason, if you are considering moving from a landline to a cell phone exclusively, you may find that you need a better signal at home, and a cell phone booster is a great way to get it.

What is dB gain?
Gain is defined as the compressing of the vertical component of the antenna pattern, in effect causing the radiation pattern of the antenna to reach out further toward the horizon. It is not the creation of power, but rather a simple refocusing of energy from all directions to a specific direction. Gain is measured in decibels (dB). Vertical antennas are in fact quite directional, except in the horizontal or azimuth plane. 
What is the difference between dBd & dBi?
Gain can be expressed in many different ways. The two most common are dBd and dBi. Gain expressed as dBd is a measure referenced to a half wave dipole. The dBi measure is referenced to a theoretical dimensionless point source, with a completely spherical radiation pattern. Since it has no directivity, any real antenna without excessive loss will provide some amount of gain when compared to the isotropic.
What does dual band mean?
Many networks operate on a dual band system, e.g. (800Mhz & 1900Mhz in the USA) & (900Mhz & 1800Mhz in Europe). Depending on how the network is configured will determine which frequency your phone might be operating on at any given time. Some networks seamlessly switch between both frequency bands unknown to the user. Due to the fact that so far the 800Mhz cellular band provides a stronger and more stable signal, the some networks switch to this frequency band when faced with obstructions between the cell phone and the cell site to keep the signal or when you have left a metro area. Other networks may setup their voice communications on the lower frequency band and data communications on the upper band. This is why a dual band booster is always the better option.
