The Power Line Communication That Effectting The Radio Communication, And The Radio Management Of That

With the development of communication technology, more attention has been paid to PLC (Power Line Communication).Using existing Power lines to achieve data communication has many advantages, including decreasing the building cost of communication network, predigesting the communication equipment, taking effect quickly, hard to be destroyed, keeping in step with the building of Power electric system and so on. It can realize the transmission of data, audio and video while transmitting the Power.Aim at the problem that there is electromagnetic radiation around the power line communication of low-voltage network,this article had rounded summarized the development of the PLC thechnology in china, how to measure the electric-filed intensity of PLC in and abord,and also rounded summarized the standard of the limited value. In the near field conditions.electromagnetic that under the CISPRI6 standard multiply 337O(or add 51.5dB) is called the electric-filed intensity.the article also shows how to calculate the error thought this method mentioned above.and the article puted forword a method that can calculate electric-filed intensity from magnetic field that bacing on a wave impedance ,and the electric dipole of the wave impelence change along with the frequence.And the method mention in the article can practically mersure the level of electromagnetic radiation of the PLC system,and can test the difference frequence,also can measures the intensity of radiation of the PLC in difference distance,thought above,we can judge the factor that effectting the intensity of radiation.we can also analysis the electromagnetic radiation level that effectting the radio communication.so we can take advice for good controling the spectrum and making the standard about measuring the electromagnetic radiation of low-voltage network and limited value.
