Some devices that have sometimes lose the WiFi signal in parts of the House. Searching on the internet, andncontrei this reflector to WiFi antennas and really works! You can significantly improve the speed and signal strength of wireless networks doing this small parabolic reflector in house. The first step is to download the picture below and print.
Then cut if the two figures and foil tape aluminum foil on the front side of the rectangle, where it says freeantenas. Then make small openings in six locations indicated by lines inside the rectangle, where will be later fitted tabs of the parabolic reflector. In the figure below we have already coated rectangle of aluminum foil with the tabs already inserted. To be secure the flaps pasted the reflector with durex.
If all goes well you will have a parabolic reflector as this in figure below. To fit the antenna of your router or WiFi receiver must make two cuts on the cross at the top and bottom where it says WindSurfer (indicated by an X).
Below the reflector with the cut to fit on the router antenna.
See how it looks finished mounting, with the parabolic reflector antenna embedded in the.
To ensure that work done this before putting the parabolic reflector. The WiFi signal on my room, by measuring using the WiFi on my mobile analytics UMI X 2, floated between 66 and 70 DBM.
After the reflector installed on the router I have between 56 and 60 DBM. At least 6dBm over sign!
Now let's do a quick explanation: actually, What occurs is not a signal amplification, but only an increase in directionality. With the reflector, signs that would be played back are partly oriented forward thereby increasing potency in the direction of the spotlight, Although decrease the amount of signal in the opposite direction. In other words, the reflector only guides better reception for the direction you want it to go, But if you own devices on the back of the reflector they certainly will record a decrease in signal strength.
With this reflector you can improve significantly the WiFi reception of its Chinese devices, you usually do not have good antennae. I leave a link to the original site where this antenna first appeared, and where there are also diagrams of irradiation of this adaptation. If you are already in need of a better WiFi router let also a link to all found in DealExtreme:
