High speed downhole communications network having point to multi-point orthogonal frequency division multiplexing
摘要：
A method and related apparatus for high speed digital data conmunications from multiple distributed modems to a single central modem or a common transmission medium. In one embodiment, multiple downhole modems, with each modem associated with a geophone, transmit data to a surface modem over a single transmission medium. In a second embodiment, multiple transmission mediums are used and a plurality of downhole modems associated with geophones communicate to the surface modem over the downhole modem's respective transmission medium.
摘要（中）：

一种用于从多个分布式调制解调器到单个中央调制解调器或公共传输介质的高速数字数据通信的方法和相关装置。 在一个实施例中，具有与地震检波器相关联的每个调制解调器的多个井下调制解调器通过单个传输介质将数据发送到表面调制解调器。 在第二实施例中，使用多个传输介质，并且与地震检波器相关联的多个井下调制解调器通过井下调制解调器的相应传输介质与地面调制解调器通信。
