- WHY REPEATER
1.1. Reason
(1) Blind or weak signal areas are formed if the buildings are too for away from CELL TOWER, or the buildings themselves shield or absorb signals.
(2) There are too many complicated signals in the higher part of the building, therefore ping-pong switching effect has been formed and the signals fluctuate a lot, there are annoying noises during phone calls and call drops according.
(3) Elevators and basements are well-known for blind areas.
(4) Downtown areas of the cities, which congested with many high-rise buildings, are usually the weak or blind areas.
(5) The remote villages, mountain, hills, valleys, etc, are mostly populated areas with quite few mobile users, so the main target is to send coverage to there areas, and it will not be worthy installing a CWLL TOWER, therefore a booster is a quite good option.
1.2. Solution
Our consumer repeater is the perfect solution for providing a wireless improvement in the cellular reception of a home, office, restaurant, VIP room, apartment, building or shopping mall, in the quickest time possibly. One repeater covers 300 to 2000 square meters.
Below diagram shows how simple and fast for the repeater system is installed and works effectively.
One Yagi antenna, as Outdoor antenna, is installed at the top of the roof to pick up good mobile signal from outside, and send though coaxial cable to repeater to amplify the signals significantly, them the output signals are divided into two signals by one 2way splitter, sent to two indoor Omni antennas and finally transmitted into area. Very clear phone call or high speed mobile data are immediately achieved withed within the area.
3. THE REPEATER SYSTEM
4. Installation
The repeaters should be used to cover the Indoor area. Humidity and temperature of working environment can affect the reliability of repeater. So, temperature, humidity, dust, interference, power, space requirements and other factors should be considered during installation of repeater.
4.1. Installation Location Requirement
(1). It is appreciated that repeater is installed in a cool, dry and ventilated room without erosive gas and smoke and without leakage on its proof.
(2).Or a cool and ventilated wall of which sun-proof and waterproof is expected.
(3).Besides above, common wall, tower or high pole is ok too.
(4).Installation height should be easy for RE cable wiring, heat dissipation, security and maintenance.
(5).Have a set of independent and stable power supply.
(6).Have lighting conductor in the building, tower or high pole with enough strength or stability.
4.2. Installation of Outdoor antenna
It is very important to choose the Outdoor antenna location in order to get the best signals.
Testing the signal strength received from Outdoor antenna mounted in site by mobile phone:
Please select the top of install the Outdoor antenna if total floors are less than 7 floors, and shall try your best to select places like balcony or platform lower than 7th floor for Outdoor antenna if the building are over 7 floors, because the mobile signals are clean at less than 7th floor.
The mobile phone shall display full bar signals in location where the Outdoor antenna is installed
The phone calls or data transmission shall be smooth and by 3 times testing in location where the Outdoor antenna is to be installed
As shown from the above illustration, testing the signals from A to E, and select a best place that displays full bar signals to install the Outdoor antenna.
Selecting the installation direction of Outdoor antenna.
The Outdoor antenna shall point to the directions of the tower, and it would be much better to keep line sight.
In order to avoid interference, please note that Outdoor antenna should be far away from the following objects of metal, high-voltage line, and RF antenna and high-voltage transformer.
5. Indoor antenna installation
Proper antennas shall be according to the site conditions and the requirement. And more than one antenna can be used with the repeater.
(1). Indoor ceiling Omni antenna is suitable to be installed in the center and radiate all directions.
(2). It is better to use a directional panel antenna when the coverage shape is long and narrow (corridors, long row of houses in two sides, tunnels or elevators or rural open space).
(3). The small whip antenna to be installed use for small room or apartment. It is very convenient for simple use with a good result.
