Q:The repeater is not connected

Repeater (Repeater) weighing and sending device is one of the most simple, but also the most widely used interconnection equipment. Repeaters are only suitable for Ethernet and can link up two or more than two Ethernet links. The repeater amplifies and amplifies the data signals transmitted over the cable, and then retransmit them to other cable sections. For protocols above the link layer, several sections of cables interconnected by repeaters are not different from a single cable (except that the interrupt itself causes a certain time delay).

Q:Elevator 3 party intercom, no repeater can connect how many meters

Depends on what kind of machine you are, the old 4~6 core line of transmission is relatively far, I have done 200 meters or so, the new 2 core in the case of external auxiliary power supply, the most done 300 meters

Q:What does the subway rep repeater mean?

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. Repeaters are designed to solve this problem. It completes the connection of the physical circuit, amplifies the attenuated signal and remains the same as the original data. In general, both ends of the repeater are connected to the same media, but some repeaters can also do the switching of different media. In theory, the use of repeaters is unlimited, and the network can therefore be indefinitely extended. In fact, this is impossible, because the network standards are specific to the delay range of the signal, the repeater can only work effectively within this set of regulations, otherwise it will cause network failure.

Q:Wireless repeaters are restored to initial strength regardless of how weak the signal is What is the principle of a wireless repeater?

The transmission of radio waves by the relay station is that the communication areas are divided into grid like signal intervals, because these small cells are gathered together without exception and are like honeycomb, hence the name "cellular communication"!

Q:What are the layers of routers, switches, repeaters, gateways, bridges and so on?

Physical layer - mechanical characteristics, physical standards, bit, HUB (Hub: shared bandwidth, no collision domain, no broadcast domain)

Q:About repeaters and common twisted pair problems

The function of the repeater is to regenerate and transmit the received signal so as to increase the distance of signal transmission. It is the simplest network interconnection device that connects two or more network segments of the same network.

Q:Who used the WiFi repeater? Is it easy to use?

No repeater is where you WiFi signal is not strong, like the Internet, repeater receive signals and then zoom in, let you before where the signal is not good can do, this is a function of repeater, a bridge router is also the same effect, 2 of the price difference is not much, the function of the router more than a repeater.

Q:Why do home networks typically use routers? Repeaters, bridges, and the like? What is the name of a direct link modem for a network?

Repeater: the 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. Repeaters are network devices that regenerate and restore signals.

Q:Where is the difference between a wireless repeater and a signal amplifier?

Yes, of course. The relay is to receive the signal of a wireless router and then share it, so that the signal of the original wireless router will be extended by relay, and the other signal will be transmitted directionally.

Q:What's the difference between unlimited wireless trunking and wireless bridging?

Normally。 Links between small LANs used primarily for two different locations. Used for remote network point to point or point to multipoint data communication.. And. In order to ensure the stability of bridge. Normally。 When the device opens the bridge function, it will close the intervention function of the common network card. That is, peer to peer communication. Wireless devices cannot be connected wirelessly.
