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:Which of the two WiFi repeaters is good?
Repeaters are better off with routers, and the faster, of course, the better, but if the repeater is wireless, the network speed may be greatly reduced, or it may fall by half.
Q:What's the difference between a wireless AP and a relay router?
Wireless AP is the use of wireless devices (mobile phones and other mobile devices) users access to the wired network access point, turn the wired broadband into wireless WiFi, this WiFi is AP.
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:How to make a notebook wireless relay
XP system is not available, you can use win7, 8 systems have their own trunking function. But the cell phone still doesn't work.
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: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: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 difference between relay and bridge?
The relay can be different from SSID, and to be exact, the difference between the two is the allocation of the device's IP address to the latter. The relay is allocated by itself, and the bridge is assigned by the superior route. The relay is active, and the device is connected behind the line, regardless of the routing of the higher level. The bridge is passive and must be routed by the higher authoritiesA radio relay can be understood as a device that receives signals from other devices. Re launch with one's own center. Mainly used in areas with weaker signals. For the expansion and amplification of wireless signals.
Q:Is the bus relay fiber interface integrated with the bus repeater?
Optical fibers use optical pulses to transmit information along the optical line, instead of using electrical impulses to transmit information along the cable. At one end of the system is the transmitter, the starting point of the information to the fiber line. The received electronic pulse information of the transmitter is derived from the copper wire cable, and then the information is processed and converted into an equivalent coded optical pulse. A light emitting diode or an injection laser is used to generate an optical pulse, and a lens is used to focus the light pulses into the optical fiber medium so that the light pulses are transmitted along the line in the optical fiber medium. The total internal reflection principle shows that the optical pulse easily eye optical line movement, optical principle of total internal reflection shows that when the incident angle exceeds the critical value, the light will not overflow from the glass; on the contrary, the fiber will be reflected back to the glass if the above do not want to see, look at this: is by resending the data signal or forward, to expand the network transmission distance to generate signals (i.e., amplifying and shaping of the original signal). Principle: a repeater is a device for connecting network lines, often used for two-way forwarding of physical signals between two network nodes. The repeater is the most simple network interconnection equipment, mainly to complete the physical layer, is responsible for the physical layer of two nodes according to a transmission of information, copy, adjust and complete the signal amplification function, in order to prolong the network length.
