Q:WIFI how does the repeater amplify the amplified signal?
The realization method of wireless relay is to increase wireless devices, by the relay to the host device to transmit signals, the increase of transmission distance, intermediate relay equipment after more mobile terms called micro cellular system, because no routing relay equipment and DHCP and other more than three layers, is also transparent to users. Is that users feel like intermediate relay equipment, or connect to the same device, through the relay to amplify the signal distance, avoid attenuation.
Q:Japanese fire automatic alarm system. How can I dial the repeater?
Now generally electronic dial code, S+S - that is loop bus. Passive contact is an action feedback signal, the need to relay things to 24V, in the 24V jumper to the beginning of the regular. The action of the module is to relay the 24V, and it is cut.
Q:Can Tengda F6 repeaters be controlled by mobile phones?
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:How can I find the coverage area of repeaters?
(1) types of repeater stations for mobile communications;From transmission signals, there are GSM repeater and CDMA repeater station;--- from the installation site to outdoor machines and indoor machines;--- from the transmission bandwidth, there are broadband repeater and selective frequency (selective channel) repeater;--- from the transmission mode, there are vertical repeater, fiber transmission repeater and frequency shift repeater. ?(2) the type of mobile repeater;GSM mobile communication repeater stationGSM mobile communication repeater is a way to solve the blind spot of the base station coverage. The erection of the repeater can not only improve the coverage effect, but also greatly reduce the cost of the investment base station.GSM repeater is a communication device designed to eliminate the small signal blind area or weak signal area of GSM900MHz/1800MHz band mobile communication network. Blind signal is widely used in underground shopping malls, parking lot, subway, tunnel, high-rise buildings, entertainment, office or private residential elevator cannot reach the base station signal, but also has a fairly good coverage for the elimination of weak signal district city due to the impact of the edifice of several rural outdoor local signal shadow Yin the side or outer zone.
Q:How is the Tengda 11n wireless router set up as a repeater?
I do not have a router in Tengda, there is no way to show pictures, but the settings are almost the same, in the wireless settings, there is an open WDS option, open on the OK
Q:Ask the difference between the base station and the repeater
The base station is the core part of the mobile communication network. The base station includes the antenna, the tower, the computer room, the base station equipment, the power cabinet, the battery pack, the BTS, the BBU, the cable and so on;
Q:Routers, repeaters, two computers are connected, and how to form a LAN
Routers do not have special settings (but to open the DHCP service), and the repeater uses the AP mode (to turn off the DHCP service and modify the repeater LAN address with the same network segment of the router, but not IP).If wireless, it's simplerRouters do not have special settings (but to open the DHCP service), and the repeater relays the signal to the main router via the wireless signal in the relay mode, and forwards the signal.
Q:The greater the power, the better the ability of the WiFi repeater to receive the signal?
The sensitivity of the receiver generally has a limit, or the maximum reception sensitivity is a constant, and the reception capacity is limited by the sensitivity constant. It does not change as the power of the transmitter increases or decreases. It has nothing to do with the transmitted power. They are two different devices. It can only be said that the greater the power, the stronger the received signal.
Q:Can routers be plugged in after the relay is successful?
Please note that when you set up a router to open the DHCP server, the local connection of the computer should be set to automatically obtain the IP address.
Q:Repeater with output network socket
A common router can act as a repeater, and as a repeater, the LAN port can output the network
