1.Basic Repeater System Installation
Your system should come with at least the following items:
2.In-Building Booster Installtion Sloution
Above diagram illustrates how a repeater extends signal coverage to every corner of the building. The exterior yagi donor antenna placed outside of the building where it has easy access to a BTS. Signals from the donor BTS are then introduced into the repeater. After amplification by the repeater, signals are divided into several parts by splitters or couplers and sent to the interior service antennas. The service antennas are placed inside the building where it can extend radio coverage to the dead zones. Therefore, the subscribers have seamless access to mobile signal from every corner of the building. Through a high-tech, reliable repeater made by Remotek and the applicable system design, the QoS for applications like voice call, video call, video streaming, and data services will be guaranteed to each customer.
3.High-Rise Building Booster Installation
The diagram illustrates signal coverage extension for a high-rise building. Suppose the facility has 13 levels, 11 floors and 2 basements. For example of a scenario, Floors 9th to 13th level suffering the " Ping Pong Effect " . The first to 8th level will be the " signal fades " areas. The basement and inside the elevator are " dead spot " which can not access any signal from base stations. A way of solving this problem is to install a micro base station, a cable booster and indoors distributed antennas to extend the coverage of mobile signal within this kind of large building. Users will see a noticeable increase in the range of their mobile networks as the repeater is indeed putting out a stronger signal.
4.Mountains Repeater Installation
When coverage extension becomes difficult due to hills and mountains preventing line-of-sight with the BTS location, using a RF or fiber optical repeater to enhance signal coverage provides an ideal solution. Deployment of repeaters can minimize the rollout time and site acquisition is much easier approved.
Above diagram provides a typical installation layout of an outdoor project. The repeater is connected via coaxial cables to donor and service antennas. Ideally to maximize the output power of the repeater, donor and service antennas should be installed on opposite sides of the mountain to take advantage of mountain as an isolation barrier
5.Tunnels and Subways Installtion
Delivering a reliable and seamless mobile communications for underground subway and tunnels presents operators with many challenges due to the limitation of RF propagation and penetration. For the most part subscribers in these areas are unable to receive mobile signals to establish a call connection. In order to provide coverage to these areas, a cost effective and reliable solution may come from a RF or fiber optical repeater.
Deployment example 1:A 4km tunnel is served with two 5W repeaters.
As the diagram illustrates, donor antennas are located on both ends of the tunnel. Signals received from the BTS are amplified and then projected into the tunnel through the service antenna, providing coverage to the length of the tunnel.
Deployment example 2: Fiber Optical Repeater with micro-cell
Solution to provide coverage to underground sub-ways, a mix of micro-cell and fiber optical repeater will enable an operator to provide full coverage to the underground subway network.
With the fiber optical repeaters, consisting of a master and a remote unit, signal is tapped from the micro-cell, where the master unit will convert to an optical signal for transport down the fiber cable to the remote unit; in turn the remote unit will re-convert the optical signal back to RF signal and boost the signal for distribution via antennas or leaky cables providing further coverage in the subway.
6.Highway Repeater Installation
Highways provide a good example where deployment of new BTS' s is not only cost ineffective but under utilization of BTS capacity. In most practical situations providing coverage to highways provides convenience and for emergency purposes, but BTS capacities along highways are extremely under utilized. Also with growing intolerance from subscribers to call drops, operators are force to provide coverage along the full stretch of the highway.
The diagram illustrates a simple deployment of a repeater to extend coverage to a road around a mountain. Highways tend to be long winding roads obstructed by hills in between, leaving blinds spots where the BTS signals can not reach. Installing a repeater will provide coverage into this area, without a repeater to extend coverage; mobiles traveling around the hill will result in a call drop.

Tired of poor reception on your mobile phone? Troubled by intermittent communication during your call?This device,Mobile Signal Booster,now can remove all these troubles.
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
cellphone range.It can increase the signal strength of your mobile by up to 500%.
Application situations
Mobile Signal Booster is specially designed for the “blind zones” of offices, family rooms, underground
parking garage, cars, lifts, elevators, factories, bars,supermarkets, mountain areas,marines, deserts,
high ways,tunnels,etc, where the signal is very poor. Or in spite of full bar signals on the mobile phone,
there is a break in voice leading to call clarity problem. Simply place the mobile phone booster in such
places, you'll be astonished with the huge gain in both the incoming reception and outgoing transmission
levels as the mobile signal booster goes to work!

Improving Long Distance Calls
Cell phone boosters help us to achieve long distance and more reliable communications. The antennas
with the magnetic mount or the glass mount can be used in the car as well as in boats and trucks. The
indoor cell phone coverage can also be increased to cover an area of 2500 square feet.
The booster is also used to enhance wireless applications such as cell phone internet use as well
as text messaging.
Dual Band Cell Phone Boosters
Whether you use your cell phone for business or just social communication at home, a booster is very
necessary. With a booster you will never have to lose signal in places or environments which are very
important for communication.
There are dual band cell phone signal boosters available for use with a dual band phones. There is
also the wireless extender system cell phone signal booster that is capable of improving the signal strength
of the PCS phone through signal amplification up to an area of 2500 square feet.
In case you need additional coverage, you can simply introduce a wireless extender PCS indoor antenna
which is sold separately. You can place the antenna on the roof and then run the RG6 coaxial cable to your
room where you will place the base. Once it is connected there will surely be fewer dropped calls. The signal
booster can also be used for other wireless applications, as well as cell phone internet use and messaging
through PDA. The signal booster is easy to install,detailed install infomation,please check
Reasons for weak signal
Rural areas
In many rural areas the housing density is too low to make construction of a newbase station commercially
viable. In these cases it is unlikely that the service provider will do anything to improve reception, due to the
high cost of erecting a new tower. As a result, the only way to obtain strong cell phone signal in these areas
is usually to install a home cellular repeater. In flat rural areas the signal is unlikely to suffer frommultipath
interference, so will just be heavily attenuated by the distance. In these cases the installation of a cellular
repeater will generally massively increase signal strength just due to the amplifier, even a great distance
from the broadcast towers.
Building construction material
Some construction materials very rapidly attenuatecell phone signal strength. Older buildings, such as
churches, which use lead in their roofing material will very effectively block any signal. Any building which
has a significant thickness of concrete or amount of metal used in its production will attenuate the signal.
Concrete floors are often poured onto a metal pan which completely blocks most radio signals. Some
solid foam insulation and some fiberglass insulation used in roofs or exterior walls has foil backing, which
can reduce transmittance. Energy efficient windows and metal window screens are also very effective at
blocking radio signals. Some materials have peaks in theirabsorption spectra which massively decrease
signal strength.
Building size
Large buildings, such as warehouses, hospitals and factories, often have no cellular reception further than
a few meters from the outside wall. Low signal strength is also often the case in underground areas such as
basements and in shops and restaurants located towards the centre ofshopping malls. This is caused by both
the fact that the signal.
Multipath interference
Even in urban areas which usually have strong cellular signals throughout,there are oftendead zones caused by destructive interference of waves which have taken different paths (caused by the signal bouncing off buildings etc.).
These usually have an area of a few blocks and will usually only affect one of the two frequency ranges used by cell
phones. This is because the different wavelengths of the different frequencies interfere destructively at different
points.Directional antennas are very helpful at overcoming this since they can be placed at points ofconstructive
interference and aligned so as not to receive the destructive signal.
Diffraction and general attenuation
The longerwavelengths have the advantage of being able to diffract to a greater degree so are less reliant on line
of sight to obtain a good signal, but still attenuate significantly. Because the frequencies whichcell phones use are
too high to reflect off the ionosphere asshortwave radio waves do, cell phone waves cannot travel via the ionosphere.
