11 Q: The power we used is 50 Hz, I would like to ask your company's power line modem which frequency will not interfere with the frequency of power supply?
      A: Problem of power Line Communication frequency, frequency ranging from 4.3 trillion to 20.9 trillion, during this band inside, the power will not affect. Opposite, the 50 Hertz power will shield the outside world. In this regard we have already done very stringent test.

12 Q: How much modification the use of power-line Internet access to the grid? Increase how much in the number of ancillary equipment required?
      A: It doesn’t need the transformation of the power grid. The need for a local client device, the broadband signal into a power signal is injected into the power line, and the rest is the terminal equipment - power line modem (Cat Power).

13 Q: What is the volume of the current Product WD-85M (Cat Power)?
      A: much smaller than the cat on the market, slightly larger than an ordinary mouse.

14 Q: Can foreign products enter the Chinese market directly?
      A: Can foreign products enter the Chinese market, there is a "acclimatized”, that is the foreign to the Chinese understanding of the power network, this problem is the most important, as long as they understand the power of our network, at U.S. network to carry out a variety of tests, that is, we feel that they should take some time, it will be possible to enter.

15 Q: If using power line, communication socket need replacement?
      A: No.

16 Q: If you bought a cat power online, whether installing them are very troublesome?
      A: Plug and Play, but also has a little computer knowledge.

17 Q: PLC power line communication with the short-wave communications, there is no mutual interference?
       A: After our EMC laboratory tests, and has passed FCC and CE certification. There is no interference of sub-standard.

18 Q: Power Line Communication technology to existing power facilities are not complete but a very attractive country, but the vast majority of the country the world has the power supply housing, and the phone is not very popular, the industrial countries, cable Internet technology existing technology can be used as supplementary.
      A: power line communication technology and a variety of Internet technologies, are in fact provide a way and a complement and a complementary relationship with the existing power line communication technologies, defined as an extension of access network technology, once the access that wireless or direct-to-home broadband Say or power line communicationitself is a very good extension methods.

19 Q: How to do the use of power on peak time?
      A: the case of peak velocity may be slightly down, this is the physical nature of the grid, but relatively short time. Test time can feel, not really a time when the Internet will certainly be able to feel that here there is a concept of the Q title to shield the media reported that the peak time of the power voltage changes the impact of cats, in fact, at peak and non-peak time, voltage changes are small, after testing it is not affected, mainly the size of the load current change.

20 Q: low-voltage power transmission lines on 1 trillion to 34 trillion of the carrier signal, how about the transmission distance?
      A: Ideally, at the actual environment, the transmission distance approximately 300 meters around; at a relatively poor environment, but also can lead to more than 100 meters.

21 Q: Network IP address changes, the power line modem sometimes Why should not use it?
      A: Reset the network IP address (the operating system re-installation) or modify the IP address, power line modem required power reduction, can be recognized before the Internet.

22 Q: How to judge the computer with the power line modem communications is normal?
      A: According to user instructions to check whether the IP address settings are correct; DOS mode, use Ping command to Ping own IP address, a length of 32 bytes, if Ping can, then the computer with the power line modem communications normal.
