Q:Broadband lines over 300 meters. Can I use repeaters?
As far as your network line condition is concerned. It can be said that five types of network cannot be installed. The distance of 300 meters is really too far away. As for the use of repeaters. Indeed, the distance to extend the signal transmission can be limited. You have to think about a lot of problems. For example: to relay equipment installation problems, power supply problems, lightning protection issues, security issues, and so on.
Q:What are the functions of repeaters and what are their characteristics and disadvantages?
A repeater is a connection device above the network physical layer. Applicable to the same two types of network interconnection, the main function is to transmit or forward data signals to expand the distance of network transmission. A repeater is a network device, a physical layer device for the OSI model for signal regeneration and reduction
Q:Japanese fire automatic alarm system. How can I dial the repeater?
Fire control module is also called input and output module, which is an important part of fire fighting linkage control system. It is used in automatic fire alarm system to connect smoke exhaust valve, air supply valve, fire damper and so on. The module has a pair of normally open and normally closed contacts. The external contacts of the module are connected with the external circuit to realize the linkage control of the external equipment. Domestic fire alarm manufacturers are numerous, here introduces several input and output modules.
Q:What is the walkie talkie relay station?
Radio relay station is used to increase the distance of the radio communication equipment, when two walkie talkie over a distance range of radiation radio signals, walkie talkie will not receive effective signal, then you must use the walkie talkie relay station. The function of the relay station is to forward the received signal and complete the relay between the signals.
Q:How can I use a wireless repeater where there is no power?
Where there is no power supply, if the wireless repeater is 12V, it can be powered directly by the 12V battery.
Q:What are the WiFi repeaters that can receive signals hundreds of meters away?
A relatively common solution is the use of electric cats, which use electrical wires to transmit network signals, usually sold in pairs. Cat Power earlier do not have dial-up function, and there is no built-in wireless module, and can be used independently, need to use a router, which is inserted in the socket near the router, the router LAN port from a power cable connected to the cat, the other one can be inserted in the signal is not good room. From this a cat can get in touch with the power of a wireless AP or wireless router as a AP signal, it must be full.
Q:Routers, repeaters, two computers are connected, and how to form a LAN
Wired relatively stable, wireless remote sure speed will be a problem.Wired connection mode: LAN port + router + relay LAN port
Q:How can there be a walkie talkie in the absence of walkie talkies and repeaters? 30KM. My friend succeeded and didn't know how to set it up.
At present the intercom far more than 10 km far or in no obstacles or ideal conditions can have, you said thirty KM theory is not possible, unless he is using a digital radio base station into the network, then the conditional can interphone, there may be he cheated on you he used the relay station did not say with you,
Q:What is the difference between repeaters, routers, modems?
Repeater - as the name implies, for there will be a general signal relay, signal attenuation in the transmission process, serious attenuation will affect the normal communication, repeater can make signal "Rejuvination", but now it has been not much.The router is used for routing - like control network we send mail through the post office, each can be seen as a router, is based on the destination address you packet, the router to determine where to send.Modem is a device that converts digital signals into analog signals. In general, home phone lines are analog signal lines, our network signals are digital signals, we have to have a device for conversion, this device is a modem
Q:What's the function of repeaters in fire fighting engineering?
When the faulty part of the bus is repaired, the isolator can work itself back, and the isolated part is re incorporated into the system. The relay module is installed at the front end of each branch circuit of the two bus circuit and will be automatically disconnected when the branch circuit is short circuited.
