Product Description:





Application photoApplication:
To expand signal coverage of GSM900&2100MHz  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:Is the repeater time relay?
No, the intermediate relay, light load, can withstand the contactor coil current, is a lever like truth, can also be used when the relay switch, contactor, is responsible for small enough, the relay can be used as the indicator, the coil of the contactor is connected and disconnected,
Q:The net line is about 200 meters, and there is a repeater in the middle. Can we use it?
As for lightning, cable with plastic sheath, not by lightning theory, and you can't do lightning protection treatment, but other devices (switches, power supply, host) to do grounding switch using lightning protection switch. The cable is struck by lightning, one is induced by electricity, and the two is by lightning from other devices, which can only be done by grounding.
Q:What's the difference between unlimited wireless trunking and wireless bridging?
Wireless relay and wireless bridging differ mainly in the device operating mode. White spots are the applications. A radio relay can be understood as a device that receives signals from other devices. Re launch with one's own center.
Q:What is the difference between WiFi signal relay and WLAN extension?
Using wireless repeaters to amplify WLAN signals in the distance and then receive them with WiFi phones is possible. A wireless router refers to a wired network that transmits wireless WiFi, wired signals and wireless WiFi, and a signal amplifier
Q:The role of field bus PROFIBUS DP/FMS isolation repeater is also discussed
As far as DP is concerned, a repeater must be added every 32 DP devices according to specifications. The relay acts as follows1, photoelectric isolation signal, 2, can change the topology (if necessary, can produce a tree branch) 3, cut and cut terminal resistance4, to enhance the signal, optimize the waveform and extend the communication distance
Q:The wireless network signals received by the computer are weak. Can the central repeaters be enhanced?
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.
Q:What are the differences between routers, trunks, and bridges?
Relay (Relay) is a transmission path between two switching centers. A relay is a physical connection that carries multiple logical links.
Q:Is wireless router directly plugged into the Internet?
Can enter the wireless router settings, run the setup wizard, select the "broadband Ethernet, obtain IP address automatically from the Internet service provider (IP), then the next step completed, while opening the wireless function, set the SSID, wireless security settings and restart the router encryption settings of your WiFi environment will have a wireless network you set the SSID, connect to the internet.
Q:Should the two wireless routing be chosen as a relay mode or a bridging mode?
For home or small network users who use wireless routers, relay and bridge access is a concept.
Q:What are the functions and principles of repeaters?
Principle: when the relay coil is applied to the required voltage, the armature is sucked into the guide magnet, and the armature presses the contact spring fragment to make the contact switch on, disconnect or switch the controlled circuit. When the coil voltage of the relay is broken, the armature and contact piece return to their original position.
