Bad cellular signal is a relevant problem not only in the outback, where the technical process has not yet reached. In large cities coverage GSM operators It is also weak. Take the mixer room: shops, offices, gyms and cafes - in these places the connection may be absent at all. To in such mesal People have always been in touch, you can improve the coating artificially. Now we will tell you how it can be done at home.
GSM amplifier
How to strengthen cellular signal - InstallationThis is a fairly effective way that works through the use of an additional device as a repeater or repeater. The main advantage of the bottom method is to ensure a worthy, well-working coating. You will not need to connect the phone every time to the analog antenna With cable. This device allows amplify 3G and 4G signal. Before buying equipment, it will not be superfluous with its specification.
How to strengthen cellular signal - Installing an additional antenna
This method is characterized by ease and simplicity of installation. The resulting signal will be qualitative anywhere wherever you are. Quality communication will depend on power GSM antennas. Now let's talk about the shortcomings. To phone antenna Connects through a special connector that your model may not be. Besides antenna can deliver inconvenience when using the phone. This method is often used by sailors, since another way to solve the problem of the lack of communication on the vessel is impossible.
Cellular signal amplifier do it yourself
Such a device will allow you to stay in touch in any corner of the Earth. The advantages of using this system:
- Reducing the level of radiation.
- Elimination.
- Increase battery life.
- Enhance the clarity of the message.
- Strengthening the signal.
But since this equipment is expensive, we will tell how to make it n. Hands.
What is needed for assembly
- Plastic.
- Polymer pipe (20 cm).
- Cable (10 m).
- Wire (30 cm).
- Fasteners.
- Connecting block.
- Insulating tape.
Assembly
Wire You need to bend so that the rhombus is. To do this, retreat on both sides by 9 cm. In place of the mark, bend the wire at an angle of 90 degrees. Performance operations will make a rhombus. Drill end inside And attach the block to them. One side of the polymer pipe cut along and perform Opposite the hole.
Colmia antenna, go to connect the coaxial cable. Remove the external insulation on one of its ends and connect to the connecting unit. What we got: cable has become a continuation antennas.
Now it remains to install the device on a pillar or roof of the house. The last stage is an attachment to the plastic plate of the second end of the cable.
Installing repeater
Collect the cellular amplifier is just a floor of the case, it is necessary to set it right. The effectiveness of the functioning of the equipment is influenced by 2 factors:
- Location.
- Antennasincluded in the system.
Before installation, not superfluous will be sure In stock Signal. To do this, make a call from the phone or look at the signal level indicator.
Planning the location of the components, you can start the coaxial cable laying. First of all, make sure clean and integrity all connectors. Restrictions are available in temperature mode. External antenna You can operate at temperatures from -40 to +50, but the repeater should always be in a heated room with a positive temperature.
Adjust the amplifier
Connect to high-frequency connectors antennas and power adapter. To protect yourself from voltage jumps, use a network filter.
As the next step, the gain will be adjusted. There is one requirement to him - it must be at least 15 DB. The repeater can be configured both in manual and automatically. In the first case, the potentiometer handle is used, and the position of the internal and external antennas changes.
Under the automatic setting it is understood to set the level of the gain of the coefficient so that the output is the maximum power. The device in this case will be independent adjust Under the traffic station operator.
