摘要： A method and apparatus for maintaining network connectivity over power lines is disclosed. Such network connectivity is maintained even if various customers are covered by different power line networks or if one or more power lines in a network are unavailable to transmit data. More particularly, in order to bridge a gap in a power line network, one or more messages are extracted from a first node in a power line network and are then transmitted to a second node via free space transmission, illustratively wireless radio frequency (RF) transmission conforming to one or more of the 802.11a, b or g standards. When those messages are received at the second node, the message is injected back into the power line on the other side of a gap in power line coverage. This method of transmission backup will continue until power line connectivity is restore upon which the preferred method will be selected and used.
摘要翻译： 公开了一种通过电力线维护网络连接的方法和装置。 即使各种客户被不同的电力线网络覆盖或者网络中的一个或多个电力线路不可用于传输数据，也保持这种网络连接。 更具体地，为了桥接电力线网络中的间隙，从电力线网络中的第一节点提取一个或多个消息，然后经由自由空间传输被发送到第二节点，例如无线射频（RF） 传输符合802.11a，b或g标准中的一个或多个。 当在第二节点处接收到这些消息时，消息被重新注入到电力线覆盖的间隙的另一侧的电力线中。 这种传输备份方法将继续，直到恢复电力线连接，将选择和使用优选方法。

摘要： A system according to embodiments of the invention may comprise a first communication path that converts an optically-modulated source signal to a radio signal based on a detected degradation in a quality of a received optical signal, and a second communication path that converts a radio-modulated source signal to an optical signal based on a detected degradation in a quality of a received radio signal. The system may therefore adapt to diverse weather conditions to improve the reliability of a communication link.
