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:Home signal is poor, how to connect the cat, routing and repeater to make the signal stronger?
Well, the repeater will amplify the half of the signal to 1.5 times, and your room should be good. I guess your house will be 150 square meters at most.
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:Differences between routers and switches and repeaters
Switches operate on the second layer (link layer), forwarding packets at the MAC address, and each port of a collision domain (collision termination) is itself in the broadcast domain. It can isolate the conflicts between ports and inhibit (not eliminate) the broadcast storm (after learning the address, no need to re broadcast).
Q:Repeaters, hubs, two - layer switches, three - layer switches and routers work on the OSI reference model layer
Repeaters and hubs are first - tier physical layers that work as the OSI reference modelThe two layer switch operates on the second layer of the OSI reference model data link layerThree - layer switches and routers operate on the third - layer network layer of the OSI reference model
Q:What is the function of the repeater in the automatic alarm?
Line repeater, which can be powered by an external power supply, preferably with batteries. Generally not connected from the host.
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: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:What is the principle of fiber repeaters?
There are more erbium laser repeater is adding rare metal in a fiber, the nearby photon in a state of activation, there is a small amount of light once into the fiber segments, can impact these active light source, the optical signal instantly increased several times, thus the optical signal amplification.
Q:What is the principle of fiber repeaters?
First, the transmission of optical signals is explained. When the transmission of the optical signal in the optical fiber with a longer distance and the signal decreased, when less than a fixed value when the optical receiver at the receiving optical signal can not correctly identify signal encoding, will lead to error, so at a certain distance from the optical fiber transmission, with a fiber optic repeater, the light amplification the signal can support long-distance transmission, similar to the gas station.
Q:The greater the power, the better the ability of the WiFi repeater to receive the signal?
The greater the power, the stronger the ability of the WiFi repeater to receive the signal. Because the transmit power and reception capability are two different physical parameters.
