Based on analyzing the theory of OFDM (Orthogonal Frequency Division Multiplexing) and characteristic of cable transmission, the Modem of high speed cable telemetry system has been designed.

通过对OFDM(正交频分复用)技术原理及测井电缆传输特性的分析，设计出满足测井电缆所需的调制解调器。

Through the analysis the characteristic of cable transmission, it is the first time for using the OFDM in the high speed cable telemetry system, and has given the result of this realized system.

通过对测井电缆传输特性的分析，首次使用OFDM 的先进成果，设计出新型的高速电缆遥传系统，并给出了系统实现的成果。

What is more, high-speed cable modems are a faster and cheaper alternative.

ECONOMIST: Hold the line

Even high-speed cable modems and DSL lines typically run at only one-fifth the speed needed for a full-size TV picture in real time.

FORBES: Steal This Movie

The NETGEAR D6300 WiFi Modem Router also includes a separate gigabit Ethernet WAN port for connecting to either high-speed cable or fiber optic broadband.

ENGADGET: Netgear D6300 mates 802.11ac WiFi with ADSL, risks one heck of a mismatch
