Product Description:

Application photoApplication:

To expand signal coverage of WCDMA2100MHz  which signal blind areas where signal is weak or unavailable.
A cheap and immediate solution that would allow them have clear phone calls or higher speed broad band.
No more dropped calls ! No more poor reception !
No more runing to the windows or going outside to talk on your mobile phone !

Now you can reach everywhere with signal boosters!

Q:What's the difference between unlimited wireless trunking and wireless bridging?
Normally。 Links between small LANs used primarily for two different locations. Used for remote network point to point or point to multipoint data communication.. And. In order to ensure the stability of bridge. Normally。 When the device opens the bridge function, it will close the intervention function of the common network card. That is, peer to peer communication. Wireless devices cannot be connected wirelessly.
Q:What are the functions and principles of repeaters?
Effect: the general relay has 2 or 4 pairs of normally open normally closed contact, when the coil operating normally open, normally closed variable variable normally closed, normally open, if, at this time, normally open normally closed contact is connected in the control circuit, a closed or to disconnect the other line function.
Q:The role of repeaters in Ethernet?
In the transmission of network data, data will be attenuated, if the transmission distance is too long, it may lead to data distortion, resulting in non discrimination,
Q:Should the two wireless routing be chosen as a relay mode or a bridging mode?
Relay mode. Two router SSID consistent, so that if you move back and forth between the two installed router room, you can achieve two routers between WiFi signal conversion.
Q:Repeaters, hubs, two - layer switches, three - layer switches and routers work on the OSI reference model layer
The repeater works on the physical layerThe hub works on the physical layerThe two layer switch works at the data link layerThe three layer switch works at the data link layer and the network layerRouters work at the network layer
Q:The repeater is not connected
Repeater (Repeater) weighing and sending device is one of the most simple, but also the most widely used interconnection equipment. Repeaters are only suitable for Ethernet and can link up two or more than two Ethernet links. The repeater amplifies and amplifies the data signals transmitted over the cable, and then retransmit them to other cable sections. For protocols above the link layer, several sections of cables interconnected by repeaters are not different from a single cable (except that the interrupt itself causes a certain time delay).
Q:What is the meaning of intrinsically safe CAN repeater
High reliability, perfect specifications and agreements have been used more and more in various systems of coal mines. The equipment in coal mine field has many nodes and long distance. Under the premise that the CAN bus transmission rate is certain, it can not guarantee a longer transmission distance. Therefore, it is necessary to relay the CAN bus signalBig.
Q:Can the wireless repeater amplify the signal output by wire?
If the wireless router can select AP mode when a router is used, the end users need to dial, generally the long nail flap with solid change thanks to cool routing with AP mode with whales, and when the router, and used to transmit radio signals.
Q:How do Apple phones act as WiFi repeaters?
Confirm the wireless router relay network normal after entering the "Wireless Settings" - "basic settings", you can see the wireless router's "SSID", this is to relay wireless network name, later will be used when the relay set. By the wireless signal relay cannot use the "auto" channel, some routers default will be set to auto channel, it will cause the router to restart, because different channel repeater relay failure, channel 1, 6 is 11, etc..
Q:How to connect the router Tuoshi wireless bridge repeater
Repeater is the extension of the length of wireless signals (not amplified signals), of course, is a wireless bridging function, but the use of different, so the relay can not replace the bridge.
