Range and Coverage Area of mobile signal booster

A mobile signal booster comes in various designs and each solves a different purpose in accordance with the range and the area to be covered by a cell phone booster. Each mobile signal amplifier has a different frequency according to the requirement of the user. For example, a mobile signal booster of 2100 Mhz covers up to 250 square meters area. We, ESPOW, have various of cell phone boosters for you.

Therefore, the main thing to be considered before buying mobile signal amplifier is to determine the requirement of the area to be covered by the cell booster.
It is best to place the antenna where there are 2-3 bars of signal like on the roof for optimum signal quality inside the house.

How to Differentiate Between Cell Phone Boosters by Frequency?

Cell boosters operate on different frequencies: 800 MHz, 1900 MHz and iDEN. The 800MHz frequency is compatible with Verizon phones outside of Florida and Texas, Alltel phones in selected states, and US Cellular phones in selected states. T-mobile, Sprint, Metro PCS and several other carries operate on the 1900MHz band. AT&T operates on both bands.

Often the most comprehensive solution is to opt for a Dual Band Cellular Repeater. These repeaters operate on both the 800 MHz and 1900 MHz bands, ensuring proper coverage with all major carriers (with the exception of Nextel). Nextel users in need of a cellular repeater must invest in an iDEN booster.

Cell Phone Boosters

Cell phone signal boosters are becoming very popular with people in areas where their cell phone signals are weak. Weak cell signals can be caused by a variety of issues such as poor cell tower location coverage, concrete wall construction, aluminum siding, electrical interference (large power towers), stucco ceilings and other contributing factors.

To solve the weak cell phone signal problem, manufacturers such as Wilson, ESPOW and Terrawave have created some truly innovative cell boosters and cell phone antennas designed to boost your cell signal. Choose from home cell boosters including outdoor cellular antennas, cell signal boosters, as well as auto cell boosters for use in your car or truck. Also find a great selection of cell booster accessories such as antenna cables, mounting kits and more.

How to identify the LED light quality?

        1, see the solder joints. Regular LED strip light manufacturers to produce the LED lights is the use of SMT chip technology, solder paste and reflow soldering production. Thus, LED strip light on the amount of solder joints is relatively smooth and not many joints cylindrical arc-shaped LED from the FPC to the electrode pad at the extension office. The cottage version of LED light amount of the solder joints is uneven, mostly a dot wrap fillet, and have varying degrees of tin tip appeared, which is typical of manual welding.

You can google more.(www.google.com)

        2, see FPC quality. FPC sub-rolled copper and copper are two kinds of Bonded Copper of copper foil is protruding, then look from the pad and the connection of FPC seen. The rolling of copper and FPC is closely connected as one, and can bend and will not appear any pad off phenomenon. Bonded Copper pad will appear if bent too much off, when the temperature is too high maintenance can also cause the pad off.
        3, see the LED strip light surface cleanliness. If the SMT technology and production of LED strip lightLED lights, the surface cleanliness is very good, do not see any impurities and dirt. However, if the hand-welding production Knock LED strip light, no matter how clean the surface, there will be residual traces of the stain and cleaning, while the surface of the FPC will be flux residue and solder residue.
        4, see the packaging. Regular LED lights will use anti-static packaging trays volume, usually 5 m or 10 m roll of a roll, and then outside and then use anti-static bag sealed moisture-proof. The cottage version of the LED strip light because of cost savings, while the use of recycled material disk volume, then there is no proof anti-static bags, a close look at the volume tray can be seen that the appearance of a clear label traces and scratches.
        5, see the label. Regular LED lights and the volume of bags will have printed material above the disk label instead of printing the label. The cottage version of the label is printed, and specifications and parameters are not uniform.
        6, see Annex. Regular LED lights will be attached inside the box with instructions and lamp specifications, and will be equipped LED strip light connector or deck; The cottage version of the LED strip light inside the box there is no such attachment because Some manufacturers, after all, could save the province.

How Cell Phone Repeaters Work？

Cell phone repeaters, also known as cell amplifiers, cell extenders or cell boosters, are fairly simple to use.  Most boosters consist of three major components: an external directional antenna, an internal antenna and a signal amplifier.Cell phone repeaters
The external directional antenna is typically placed outside the home or office (preferably outside a window or on a roof) and is positioned to face the nearest cell tower. In the event that you are installing the antenna yourself, a signal strength monitor is recommended to help you figure out the best location for the antenna. The external directional antenna is designed to pick up the weak signal that is being broadcast by your cellular provider.
The signal the external antenna picks up is sent over wires to the signal amplifier. The signal amplifier is what increases the signal. Your boosted signal is then sent to the internal antenna which wirelessly rebroadcasts a more powerful signal within your space.
