Increasing and Stabilizing Signals Wireless Modem

Increasing and Stabilizing Signals Wireless Modem

At this time almost all mobile phone operators in the country providing internet services, we just choose which service we want to .. .
Post this time will not discuss select-select ISP (Internet Service Provider), but how do I or tricks enhance / stabilize the 2G or 3G signal, so our internet access is more stable.

This is my own experience that had always been irritated by the HSDPA signal from the service that I use are always arising tengelam and even disappeared .. probably because much of the Internet BTSnya.sehingga often slow or frequently broken.
Currently it has not happened again because the signal is always full bars HSDPAnya .. even though I was in a closed room wall or in a room that usually do not get a signal ..

What I do is put the modem far above, in a more open area that is outside the home, on the roof of the second floor .. makes the captured signal strong and stable, no longer drowning arise.
The way used is to extend the USB cable modem .. to 12 (twelve) meters (standard 1 or 1.5 meters), this is against the theory that she was the maximum USB cable length is about 5 meters. but in reality .. CAN plus length. Maybe this will depend on the type of cable used, brand / type of modem, and the power of computer power usb port.

Modem that I use is the Huawei E270 .. even before when using a modem huawei EC325 (CDMA) wire length reaches 15 meters, and when the cable is used to huawey E270 modem, modem is not detected then the cable length is reduced and reduced so that the range of 12 meters length E270 modem working properly.

How do I connect?, What type of cable used?

1. Prepare a standard USB cable (USB cable to the modem) of good quality.
2. Prepare a UTP cable (unshielded twisted pair, is the standard cable to connect to the LAN computer network), cat 6 cat 5 or better, ie adjusted length 12 meters used (12 m not necessarily compatible with your modem, will probably be reduced in length)
3. Equipment for connection: solder, tin, insulation, scissors / pliers cutters


How to work

1. Cut (for two) USB cable modem, then peel each end.
USB cable in it has 4 wires plus 1 ground (ground wire will not be used, because the limited amount of content UTP cable)



2. Prepare UTP cable, peel the ends. UTP cable has 8 wires content in it. Because the USB cable contains 4 wires, then we only need 4 UTP cable content, but in order to increase the conductivity (reduce resistance) every two wires coupled / combined, so as if the UTP cable contains 4 wires.






3. Connect the USB cable with UTP cable, note the color of the cable so that should not be confused, solderlah each connection then give insulation.

Pick and choose the color of UTP cable-free, an important color at the end of the USB cable that one should meet again with the same color on the other end, red USB cable had to meet again with the red wire, black to black and beyond to meet .. should not be confused .. if not, could be a modem or even damaged USBnya port ..

4. To have a strong connection between the cable and good connections, good solderlah then give insulation to prevent konsleting.

5. Check once again, if you're sure the connection is, new to try, if not sure do not try and error. because if the connection is not correct can cause your computer (USB port) or modem damaged. if you still do not understand or try asking for help to friends who know about electronics.

6. if you are absolutely sure, please try, turn on the computer and connect the modem, if the modem is detected by the computer modem is staying put in the best area to receive the signal.
If not detected or USB malfunction, then the cord should be made even shorter ..


6. Having proven modem function, then place the modem in the area of the operator if the signal is strongest.

Which must be observed:
Beware of the dangers of lightning, when it's cloudy and we are not sure about the lightning rod building we are .. Just lower the better
Place in areas that do not receive direct sunlight.
Be careful also to rain .. if ya get the rain ended the ...




In the application can also be used to put the modem in the vehicle, of course with a cable connection is shorter ..
