Q:Can wireless routers be used as repeaters?: PS: if there are a lot of WIFI around, it's better to set a good WIFI name so that you can distinguish between them.

Q:What is the principle of fiber repeaters?: Black and white life explained the principle of fiber amplifiers, usually using rare metals to play a role in amplification;However, the optical repeaters will receive weak light signals from the optical fiber and convert them into electrical signals by the optical detector. After the regeneration or amplification, the light source will be excited again and converted into strong optical signals, which will be sent into the optical fiber to continue transmission. In the middle there is a process of converting electrical signals and regenerating them;The purpose of this process is to:In long distance optical fiber communication system, the loss of optical signal of optical cable line is compensated and the distortion of signal and the influence of noise are eliminated

Q:Which layer does the repeater run on the OSI model?: A repeater is a network device, a physical layer device for the regeneration and reduction of signals, and a OSI model.

Q:What is the use of the relay module in the fire fighting weak electricity system?: A relay module is a module used to connect two different devices. Powered by the DC24V bus signal, electrical isolation between input and output, the signal transmission bus isolation detector, can enhance the anti-interference capability of the whole system, and has extended bus communication distance function detector. Relay module is mainly used in the area where the bus is in strong electromagnetic interference and the length of the bus is longer than 1000m and needs to extend the communication distance of the bus.

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:What is the performance of wireless WiFi repeaters, wireless relay radio, 150m and 300m?: Wireless relay is an additional device for amplifying WIFI signals. Wireless routers are devices that provide wireless access and configure and manage wireless access policies and terminals, such as wireless routers;

Q:What's the function of repeaters in fire fighting engineering?: When the bus isolator is at fault, isolated bus part and the whole system will fail, to ensure that the rest of the system can work normally, and to determine the fault location of bus.

Q:How does the COMFAST wireless relay router use the relay function (model CF, wR360N)?: To set up WiFi wireless relay, first need to ensure the wireless router relay is normal network, in order to facilitate understanding, we sometimes also known as a wireless router to the relay router or relay signal, and we want to set up a wireless relay router is called the wireless router or wireless repeater, to show the difference, don't confuse oh.The use of mobile phone or computer to be relayed to the wireless router, wireless router to the TP-LINK for example, enter the router settings page, view the running state of the router, the router has to ensure network, if the router does not relay network, the wireless Internet is not in the following.

Q:What are the differences between a bridge and a repeater?: A, transparent bridges, simply speaking, do not need to change hardware and software using this bridge without setting up address switches without routing tables or parameters. Simply plug in the cable and the existing LAN is completely free from any impact of the bridge. The core idea of B, source routing, and Bridge source routing is to assume that the sender of each frame knows whether the receiver is on the same local area network (LAN). When sending a frame to another segment, the source machine sets the destination address to 1 as a mark.

Q:Why is the repeater full of signals, but not Internet access?: The wireless password spread signal to be input, set up a wireless password here is not new, the next set, page will pop up to view the status indicator reminder, wireless extender lights on the green or orange extended success.
