1 Q: Using wire to the Internet would have a risk of electric shock? Will not cause harm to my computer?
    A: PLC technology uses 220V voltage lines to transmit data signals. The use of the process, the user can not help but be worried about whether it will damage the computer, or even a threat to personal safety. PLC equipment has taken various measures to ensure the absolute safety of equipment used:
         1) Using the principle of the coil coupling high frequency signals will be coupled into      the power in and isolated from the electricity, PLC device data signals transmission line      may not be directly connected with the 220V wires.
         2) Circuit design, separate strong and weak circuit design to ensure that the signal will      not be any high voltage.
         3) PLC device settings over-voltage protection circuit devices, to avoid induction or      because of short circuit caused by the computer and the user's injury
         4) Net Electricity Technology Co., Ltd. Kunshan of PLC products has passed FCC and      CE certification, in line with national safety standards.

2 Q: Internet access required using PLC to increase what equipment?
    A: Internet access required to use PLC has two types of additional equipment: PLC's central office equipment and terminals PLC modem. One of, PLC modem placed in the user's home, central office equipment in general placed in the interior distribution of buildings. Units can be one central office towing dozens of PLC modem.

3 Q: use of PLC can achieve so much speed?
    A: general different PLC manufacturers can achieve equipment speed are different, the Swiss company Ascom products can lead to the greatest rate of 4.5Mbps, Korea and Xeline my WD-85M Division of PLC products for maximum speed 85Mbps, Spain DS2 products can achieve 85 Mbps, and I 200M Secretary of PLC products, the largest rate of 200M, is R & D stage, is the world's highest rate of PLC products.

4 Q: How can users use PLC?
  A: the user wants to use the PLC, necessary to support the PLC network operators. Require operators to provide Internet for export and at the user's premises in the central office equipment placement PLC. Users to buy or rent PLC modem, you can use to access the PLC.

5 Q: how the user's computer and the PLC modem connection?
   A: usually, PLC modem with the RJ45 Ethernet 10/100 interface and USB interface, Ethernet cards and USB computer interface can be very convenient to connect them.

6 Q: how about PLC transmission distance?
   A: When the power line no-loading, the point-to-point PLC signals can be transmitted to several kilometers. However, when the heavy load of power-line transmission when one or two hundred meters. Currently speaking, PLC does not fit long-distance data transmission, but if only in buildings applications, to solve the "last 100 meters" of the home, or can be competent.

7 Q:what problems will arose by the radiation power line modem?
    A: Any electrical have radiation . So radiation is not a problem, how serious the radiation is. WD-85M has passed FCC and CE certification, that the radiation is safe and reliable

8 Q: What is the difference between power Line speed and ordinary ISDN and ADSL Internet access? What speed from under the message to?
    A:In fact, power grid is the speed of 85M bandwidth, depending on how much the number of users. 12 houses as one unit, and in extreme cases, 12 are in accordance with the exception of 85M, which is around 7M. Such an extreme case, the U.S. common share, of course, this is the case, the application from the user point of view, he would not find the pace slow, because the actual situation is not the case, at the same time everyone the chance to download a file or fewer, Moreover, the general shared ADSL bandwidth for 2 trillion. ADSL downlink speed of 8M, upload speed of 512K, non-symmetric transmission; power cat from downlink are 85M, are symmetric transmission.

9 Q: Power Line as a shared medium, how to prevent unauthorized users from using the Internet? Downlink are 85M, are symmetric transmission.
    A: information in power line is structure of a switch, each of the components have a central network password, the password is constituted by the networks themselves to grasp, and only the composition of the network who know the password, without his authorization, the information does not make sense , are controlled by a password.

10 Q: wiring that a sudden power failure suddenly calls what kind of impact on the device?
      A: This has to do specifically to protect the pilot, that is disconnected or Analog calls, including the line jitter, this is the safety of the equipment to do the test, no problem.
