Application photoApplication:
To expand signal coverage of WCDMA2100MHz  which signal blind areas where signal is weak or unavailable.
A cheap and immediate solution that would allow them have clear phone calls or higher speed broad band.
No more dropped calls ! No more poor reception !
No more runing to the windows or going outside to talk on your mobile phone !

Now you can reach everywhere with signal boosters!

Q:Japanese fire automatic alarm system. How can I dial the repeater?
Now generally electronic dial code, S+S - that is loop bus. Passive contact is an action feedback signal, the need to relay things to 24V, in the 24V jumper to the beginning of the regular. The action of the module is to relay the 24V, and it is cut.
Q:What's the function of repeaters in fire fighting engineering?
Relay module works in fire protection engineering: in the bus fire automatic alarm system, a local bus failure (such as short circuit) often occurs, resulting in the whole alarm system can not work properly.
Q:The net line is about 200 meters, and there is a repeater in the middle. Can we use it?
As for outdoor, plastic sleeve must be used, otherwise the sun and rain will not change for more than two years.
Q:What is the function of the repeater in the automatic alarm?
In fact, far from the proposal of wireless transmission, many hosts can now support wired and wireless, generally 100 meters receive distance can be guaranteed, plus wireless repeaters can reach 1 kilometers
Q:RS485 photoelectric isolation relay
The 485 repeater is located in the 485 signal attenuation but also can detect the location of the signal, the 485 signal shaping in the reduction, copy the signal through the RS-485 bus transmission, so as to extend the communication distance of RS-485 bus, RS-485 bus to increase the load capacity of the role.
Q:What is the repeater used for?
Repeater (RP) is a device that connects network lines and is often used for two-way forwarding of physical signals between two network nodes. The repeater is the most simple network interconnection equipment, mainly to complete the physical layer, is responsible for the physical layer of two nodes according to a transmission of information, copy, adjust and complete the signal amplification function, in order to prolong the network length. As a result of loss, the signal power transmitted on the line will be gradually attenuated, attenuation to a certain extent will cause signal distortion, and this will lead to a reception error.
Q:How does a wireless repeater set up repeaters to enhance WiFi wireless signals?
Access points and routers play a pivotal role in the provision of radio frequency in the deployment of wireless networks. However, there are times when users need to access the network, but there are some vulnerabilities in coverage. Wireless repeaters can be a good solution when extending the range of existing access points (or wireless routers). This scheme will not add more access points and corresponding cables, so it can be our choice.
Q:What is a relay power supply?
Half duplex, that is, Half, duplex, Communication, means that at any time during the communication process, information can be transmitted from A to B, and from B to A, but only in one direction. When half duplex mode is adopted, the transmitter and receiver of each end of the communication system are switched to the communication line through the receive / output switch, so as to make the direction switching, therefore, the time delay can be generated. The receive / output switch is actually an electronic switch controlled by software.
Q:What does a repeater do? What is the 543 principle?
It is commonly used for bidirectional forwarding of physical signals between two network nodes. The repeater is the most simple network interconnection equipment, mainly to complete the physical layer, is responsible for the physical layer of two nodes according to a transmission of information, copy, adjust and complete the signal amplification function, in order to prolong the network length.
Q:What is the difference between a repeater and an amplifier in a computer network?
Just put out the network repeater delay, if the line over 200 meters may not have what information (the network connection is not a normal phenomenon)The amplifier can take the cable stretch extension, but also the signal amplification, the network is no longer a thing 200 meters
