Q:How to relay submarine fiber optic cables?

Submarine optical cable without relay and relay submarine fiber optic cable. Here, repeaters are electronic devices at the bottom of the sea, not electronic optical repeaters used in previous undersea cables (working at 1300nm wavelengths). The current submarine optical cable system works at the 1500nm window using an optical amplifier. However, if the fiber amplifier is sufficient to obtain electrical power at the end of the fiber optic cable, then such a system should also be considered a relay. Repeaters can also refer to a cylindrical containing light amplifier and pump source for light sealed containers, but if the pump source of optical amplifier is located on the shore of the laser diode, optical amplifier that is installed on the seabed is not a repeater. Based on these definitions, a relay free submarine fiber optic cable is developed

Q:Why are radio repeaters different in frequency and frequency of reception?

Hello, under normal circumstances are different frequency repeater transceiver, such as relay station receives 438 emission is 438.500, then the relay station will send to send signal receiving, so there will be a further radio signal is received.

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:Request WiFi repeater settings, I do not know the other router's model and password, but I know the WiFi password!

The first step is to find the brand model of the other router. The second step is to buy a router that is compatible with each other's router, and basically compatible with the same brand. The third part is setting up.

Q:What is the difference between WiFi signal relay and WLAN extension?

Meaning is not the same as the two WiFi signal and WLAN a different in fact WIFI is WLANA (wireless LAN alliance) of a trademark, the trademark only support the use of the trademark goods can cooperate each other, and the standard itself actually does not matter, but because the WIFI mainly uses 802.11b the agreement, so people gradually accustomed to using WIFI to call 802.11b protocol. In terms of containment, WIFI is a standard for WLAN, and WIFI is included in WLAN, a new technology adopted in the WLAN protocol. WiFi can cover up to about 300 feet (about 90 meters), WLAN maximum (plus antenna) can go to 5KM.WIFI (WirelessFidelity), also known as the 802.11b standard, its biggest advantage is the high transmission speed can reach 11Mbps, in addition to its effective distance is long, but also compatible with the existing variety of 802.11DSSS equipment. Wireless internet access has become a reality. The coverage of radio waves, Bluetooth radio coverage radius based on very small, only about 50 feet or 15 meters, while the Wi-Fi radius of up to about 300 feet about 90 meters, the office since Needless to say, is also can be used in the whole building. However, with the development of WiFi technology, the scope of WiFi signals will be wider in the future.

Q:Which is good for a WiFi repeater?

1, first insert the product on the socket, the power indicator light shows the normal work;2, with a laptop computer search and connect the wavlink-repeater signal repeater (repeater and notebook computer or can be directly connected with the cable) (Note: if unable to connect the computer to the IP instead of manual input: 192.168.10.2, after determining the third step);3. After connecting the signal of the repeater, enter in the browser address bar: 192.168.10.1, enter the setup interface;4, enter the user name and password are admin, login successful, select relay mode, to the next step;5, select the name of the router that you need to connect to, and change the name of the repeater to the name you can easily remember;6, enter the original router password, click OK, that is set successfully

Q:Why is network repeater so fire?

Because it is relatively simple and convenient, and the cost is low. For example, your living room has a router and your bedroom wireless network is poor, and you can fix it with a repeater.

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:Switches, routers, repeaters, difference?

Routers: routers work in the third layer of the OSI model, the network layer. The router uses the network address defined on the logical layer of the network layer (that is, the IP address) to distinguish the different networks, so as to realize the interconnection and isolation of the network, and maintain the independence of each network. Routers do not forward broadcast messages, while broadcast messages are restricted to their respective networks. The data sent to other networks is sent to the router and forwarded by the router. Switch: LAN switch has many ports, each port has its own dedicated bandwidth, and can connect different network segments. The communication between the ports of the switch is simultaneous and parallel, which greatly improves the throughput of the information. To further improve performance, each port can only connect to one device bridge: the bridge acts on the data link layer of the OSI schema, which identifies the MAC address of the packet. In actual operation, the bridge compares the packet location of the received data to its known network segment address and transfers the data if the packet address is not in the same network segment.

Q:What does WIFI relay mean?

WiFi relay, that is, to receive the WIFI signal, and then launched. Is to relay wireless signals, increasing the coverage of wireless signals.
