  4. Various buildings have power lines access. different from the common internet, the plc ( power - line communication ) is not a long - distance correspondence, but the " last mile ” communications access

    與常見的internet不同，電力線通信（ power - linecommunication ）由於通信線路的特點，不是一種遠距離的通信方式，它適合「最後一英里」 （ lastmile ）的通信接入。
  5. The system can resolve the noise and impedance on the power line and obviously improve the abilities of anti - disturbance and successful rate of communication. at the same time, the software realy method and arithmetic is also introduced to settle the problem of attenuation and increase the distance of carrier communication, it can satisfy the need of remote reading meter system

    該系統有效地克服了電力線噪聲和阻抗變化等干擾因素，提高了抗干擾能力和通信成功率，同時提出軟體中繼的思想和演算法並加以實現，進一步抑制了線路衰減快的問題，使載波通信的距離增加，滿足了遠程抄表系統的要求。
  6. The directional routing protocol ds _ dsr put forward by the author is the improvement of the current protocol dsr, complete routine discovery and maintenance by directional neighbor nodes routing table, source routing and directional steering. the research discovers the application of the directional antenna, compare the omnidirectional antenna can increases the networks " total throughput, obviously reduces the co _ channel interference ( cci ), multiple access interference ( mai ), enlarges the nodes " signal and interference to noise ratio ( sinr ), and because of the high gain of directional antenna can realize the communication with farther distance and less jump, end to end delay can decrease deeply, simultaneously, security of networks can be improved partially, the node energy also can be saved easily by power control
