Q:A cable line can use two wireless repeaters simultaneously

A's LAN port comes out to connect B's WAN port, sets a fixed IP to B's WAN, then connects B to be possible to access the net, such meets the computer and meets in A is not the same network segment.

Q:What is the use of the relay module in the fire fighting weak electricity system?

Relay, from the name will know. It is the module of locating and transmitting the related signals. Forward the incoming signal to the device that requires the signal. Return the signal of the equipment to the incoming party. Because there are so many terminals, it is impossible for each terminal to get a set of lines to central control, which is too expensive. Therefore, after the relay module is combined and then central control, the cost can be saved.

Q:Wireless AP, what is a repeater?

Wireless AP is the use of wireless devices (mobile phone and other mobile devices and wireless devices such as notebook computer) access point users access to the wired network, mainly for broadband family, inside the building, inside the campus, inside the park and warehouses, factories and other places need wireless monitoring, typically covering tens of meters to hundreds of meters distance, also can be used for long distance transmission, the distance can reach about 30KM, the main technology for IEEE802.11 series. Most wireless AP also have access point client mode (AP client), which can be wirelessly connected with other AP to extend the coverage of the network.

Q:What is the difference between a router, a hub, a switch, and a repeater?

Repeater：Is a network connected devices, a single function. Working on the physical layer is what you see. Used primarily to strengthen signals. General signal transmission is used when far away, equivalent to an amplifier.

Q:What level of work does the OSI seven - layer structure work with, hubs, switches, routers?

A switch uses physical addresses, or MAC addresses, to determine the destination address of the forwarded data. The router is to use the ID number of different networks (ie IP address) to determine the address of data forwarding. The IP address is implemented in software that describes the network where the device is located, and sometimes these third levels are also referred to as protocol addresses or network addresses. MAC address is usually hardware comes, by the network card manufacturers to allocate, and has been cured to the network card, generally speaking, is not to be changed. The IP address is usually automatically assigned by a network administrator or system.

Q:Wifi repeater can be used as a wireless network card, please master to help explain this knowledge

Yes, the router directly connected to the host network, and then open WDS, bridging the wireless network on it, but it is not easy to use those who rub network tools.

Q:What does a repeater do? What is the 543 principle?

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.

Q:What is SIEMENS's bus repeater?

The 485 bus can be isolated by photoelectricity to prevent common mode voltage interference. Auto switch between RS-485 bus and RS-422 bus can be supported.To put it plainly is to extend the use of network communications for example

Q:What is the difference between a repeater and an amplifier in a computer network?

The repeater signal forwarding function, the equivalent of the mouthpiece, not just for forwarding data, such as advanced relay ATM asynchronous frame relay, but also for the session and application service relay transmission; wireless network, optical network is the most used network relay, and the relay is not necessarily a transmission, can also be transfer to a plurality of base stations, such as China Mobile; relay in the process involved in supporting scheduling and scheduling algorithm, and error correction algorithm, transmission efficiency algorithm;

Q:The role of repeaters?

The function of a repeater is to increase and expand an existing signal. I will send a signal repeater, when you connect the switch relay mode (some repeaters used to relay more than) you can find yourself in the emission signal routing in the WiFi list, after the connection (to be renamed) to achieve the forwarding of the original signal, so as to achieve the goal of enhancing signal propagation.
