Q:How does ZigBee implement the routing relay function?
For example, with FastZigBee protocol, to ensure AB two terminal configuration can make two normal communication, in the distance is too far away to do communication, as long as the AB into the middle of the routing node, you can return to normal communication points, other configuration does not need to be modified.
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:Relay function of wireless router
The relay (repeater) will spread the relay wireless network coverage.For example, neighbors have a router, but the distance from the middle or more than 3 of the wall, the signal is weak. You can connect to a router with a relay so that the wireless network can cover the required range of activities
Q:What's the communication pad for?
Digital trunk board (divided into 2B+D and 30B+D), is through the 1 2M optical fiber data, provides 30 voice channels, equivalent to 30 analog telephone lines, the general situation is the use of large enterprises, hotels, and engineering units; E&M simulation of relay board is mainly used in the networking, analog relay.The above is basically the switch, the general needs of the relay plate.
Q:How do you use a wireless router to connect WIFI signals to another wireless router?
The second router refers to the router that routes the line from the first routerStep 1 connect the external network to the first router, and set the method to set the default URL of the first router to 192.168.1.1 as per the instruction manual
Q:Does the use of a higher router as a relay affect the network speed?
This is only within a certain range and may not be very effective (not very much).
Q:How to relay submarine fiber optic cables?
At present, the number of fiber pairs in each submarine cable is limited to 4 or 8. In addition, the housing standard repeater can accommodate 8 fiber amplifiers, but the 4 is enough for optical fiber, and the shell model can accommodate the repeater optical amplifier this is more than 8 times, is suitable for occasions of fiber. Amplifiers with relay submarine cables are typically about 50 kilometers apart, about half the length of the land long haul fiber optic cable system. This is necessary because the length of the submarine optical cable system is often thousands of kilometers, much longer than that of terrestrial optical fiber cables. In submarine optical fiber cables, the gain of optical amplifiers should be kept at a low level, usually only about 10dB, which is to control the spontaneous emission noise and nonlinear effects of amplification, and these effects are accumulated along the length of optical fiber cables. The input power of high and low gain power is helpful to balance the entire spectrum of the optical amplifier, this point is very important, because after the 100 amplifier, small gain difference will accumulate a huge problem. The Raman amplifier in the last section of the optical fiber can not only amplify the signal of the optical amplifier, but also realize the gain equalization in the whole WDM spectrum. The current submarine optical fiber cable system uses only C band erbium doped fiber amplifier, but because of the increase of single channel rate and multiplexing wavelength, the capacity of submarine WDM system has been greatly improved. Early WDM submarine fiber optic system, each fiber transmission 4 2.5Gbit/s channels, such as 4 pairs of optical fiber, the total capacity
Q:After setting Repeater mode, the relay effect is not obvious or unsuccessful, what can I do?
In Repeater mode, the wireless signals, SSID, and encryption modes sent by TL-WR700N are exactly the same as those of the main AP, so after setting the Repeater, the wireless cannot search for the default TL-WR700N of the SSID. In the Bridge mode, the TL-WR700N can set its own SSID and encryption mode for wireless signals, which can be different from the main AP.TL-WR700N sets the Repeater mode as a relay amplification for the front-end wireless device, first establishing a wireless connection with the main AP, and then sending the wireless signals of the main AP,The TL-WR700N setting Bridge mode can also extend wireless coverage by first establishing a wireless connection with the main AP, then TL-WR700N sends its own wireless signals for client connections
Q:What's the difference between repeaters and hubs?
The difference between repeaters and hubs is the number of cables connected to the device. A repeater usually has only two ports, and a hub usually has 4 to 20 ports or more.
Q:What is the function of relaying?
Simple to say, is used to amplify the signal in the repeater in the wire, the maximum transmission distance theory of stable five cable general is 90 meters, and general in the brand is only 70~80 meters, and then will the loss. At this point, if we still have to use ordinary five - class twisted pair transmission, we need to put a repeater in the 80 meter position, so that the line can work steadily in the length of 160 meters.
