Q:About repeaters and common twisted pair problems
At A, for example, I put a repeater, which can amplify the network signal to 500 meters. In the middle, I directly pull a 500 meter net line can be, B point and then put a repeater, connect a cable to the computer, you can access the internet.
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:How do you build bridge repeaters with Tenda and fast routers?
Home network cabling:1, there is a telecommunications cat: Telecom cat ---- router WAN port; router LAN port ---- computer;2, did not get Telecom cat: Cable ---- router WAN port; router LAN port ---- computer;
Q:Android phones do wireless relay, how can I do that?
If you do need to use mobile phone relay can, but need a mobile phone wireless module supports WDS function, which we call two WiFi wireless connectivity, a WiFi connection next door, when a hot to provide their own home. But mobile phones with this function are few and far from practical, because the cell phone's transmitting and receiving function is very small, and the battery power is also consuming rapidly.
Q:Why does the repeater always drop off?
This is normal. After the relay, the bandwidth is halved.The repeater must receive and forward frames on the same channel, which means that your bandwidth is actually split in two. Although the scope is more important than bandwidth, the rate of transmission over the remote client will be as low as 1Mbps. Because of the overhead of 802.11, only about half of the bandwidth can be used for data transmission. Because of the repeater, bandwidth is once again divided into two halves, especially when multiple users share the same channel, and thus you experience bandwidth problems.
Q:In the fire alarm system, when will the relay module be used?
A lot of water indicators, ordinary 70 degree fire dampers. With input module, fire shutter door, fire smoke exhaust valve, cut off non fire electricity, sound and light alarm (now generally bus system), no need, general use control module or call input and output module. Multi line module for smoke exhaust fan, fire pump and spray pump
Q:After wireless relay, network speed is slow, bandwidth is reduced, how to solve?
Of course, it is possible to run at full speed if the bandwidth between the routers is large and the quality of the signal between the two routers is good. However, in this case, the distance between the two routers should be relatively close, and the antennas should be kept perpendicular to the ground. The best route of sight propagation between the two antennas is guaranteed.
Q:Is wireless repeater good or wireless AP good?
Wireless AP generally refers to wireless access point.Wireless access point is a wireless network access point, commonly known as "hot spot"". The main route switching equipment and access one pure access equipment, implementation of integrated equipment access and routing, access net access equipment is only responsible for the wireless client, pure access equipment is usually used as the wireless network and expand the use of other AP or AP connection, to expand the wireless coverage, and development is the core equipment of wireless network the.
Q:Why is home installed wireless network repeater, can not get on the network?
Connection method: from the cat out of the network crystal head, insert the routing WAN port, the computer each line with the router of any LAN port connected. To set up the router, you also need a network cable, a temporary computer, and a router to set it up and then unplug it.
Q:What is the repeater used for?
Repeaters (Repeater) work at the physical layer of the OSI, the center of all nodes on the LAN, which amplifies signals, compensates for signal attenuation, and supports remote communications. Repeaters are a small invention designed to push your network signals so that they can be transmitted farther. It's like a drink stand in a marathon. When the signal passes through a repeater, the network signal picked up a cup of drink, drink, the rest of the poured into his head, throw away cups, if convinced that no one saw them, jumped on a car. Due to the effect of transmission line noise, carrying digital signal or analog signal can transmit information in a limited distance, repeater function is regenerated and sending the received signal, thereby increasing the signal transmission distance. It is the most [1] simple network interconnection device, connecting two or more network segments of the same network. If the length of the cable Ethernet Repeater often use bus standard, thinnet each maximum length of 185 meters, up to 5, thus increasing the repeater, the maximum length of the cable network can be increased to 925 meters. In general, the network at both ends of the relay is a network segment rather than a subnet. Repeaters can connect two LAN cables, re - timing and regenerating digital signals on the cables, and then send them, which are typical functions of the first layer, physical layer, in the OSI model. The effect of relay is to increase the coverage area, such as Ethernet LAN [2], the maximum length of standard single signal transmission cable is 500 meters, but using the repeater cable to connect 4, Ethernet signal transmission cable up to 2000 meters. Some brands of repeaters can connect cable segments of different physical media, such as thin coax cables and fiber optic cables. The repeater sends only data from any cable segment to another cable, regardless of whether the data has erroneous data or is not suitable for the data of the segment.
