The present invention extends the transmission distance of the Internet service using the home phone-line networking alliance (PNA) method to transmit data using an existing telephone line in an apartment complex and a building, and easily connects various devices in the home to the Internet. For home PNA gateway devices.;Home PNA is a technology that can transmit Ethernet frame using telephone line in home. It is suitable for environment where there is a lot of external noise, such as telephone line, and the line is branched into several rooms in the house, and the signal reflection is caused by impedance mismatch. Position modulation method is used. The pulse position modulation method has a strong characteristic against signal distortion caused by external noise and reflected signal, but has a disadvantage that the theoretical maximum distance that is not affected by the reflected wave is limited to about 300m at 1Mbps. Therefore, the home PNA standard specifies a transmission distance of 150m. The present invention focuses on the fact that the maximum transmission distance is limited only by signal attenuation and external noise in the environment where no reflection wave is generated in the pulse position modulation method applied in the home PNA. In addition, a home PNA gateway may be added between the home PNA centralizing apparatus and a home terminal to block reflection signals generated in the home.;The Home PNA Gateway not only extends the distance between the home PNA centralized device and the home Internet service, but also enables faster communication between the PCs in the home than the Internet service speed. It has a side effect that can be utilized as a device that can be used simultaneously.
