Log on to your computer today? Most of us couldn't do business without interactive computer capability. But without a modem for efficient data transfer, that PC or Mac on your desk would essentially be a word-processing paperweight. A noted mentor, John Bingham literally wrote the book on modems--his Theory and Practice of Modem Design is considered the major reference work by those in the industry, where he is regarded as "Mr. Modem." He invented the full-duplex modem with coherent detection in 1973 and has been at the forefront of high-speed developments ever since--culminating in the latest V.90 standard. Holder of 13 patents, Bingham has worked directly for eight companies in the Bay Area, founding two of them. Most recently with Amati Communications, now part of Texas Instruments, Bingham now consults with developers and is finishing his latest book on xDSL (expanded Digital Subscriber Line) technology that is allowing copper lines to challenge fiber optics for individual-subscriber, high-speed data transfer.
