    The first edition of this book was published in 1986 by Howard W. Sams Co., then a subsidiary of ITT. When Sams was sold by ITT, it changed its direction of interest to computers and terminated its list of radio communications books. Since that time, many readers have requested that I reissue this book. I am beholden to John Wiley and Sons, Inc. for its willingness to publish this second edition. Cellular systems have proven to be both high capacity and high quality systems. However, in a realistic situation, due to the frequency re-use scheme for increasing capacity, cellular operators always struggle between quality and capacity, putting all co-channel cells closer together for capacity or putting all co-channel cells farther apart for quality. In August 1985, I was invited by the FCC to give a public presentation on "Spectrum Efficiency Comparison of FM and SSB." My analysis concluded that because of frequency re-use in cellular systems, there was no advantage in splitting the FM channels for capacity. The spectrum efficiencies of FM and SSB are the same. In 1987, I was the first co-chairperson of a newly formed CTIA subcommittee of Advanced Radio Technology (ARTS) and led the cellular industry in setting the requirements for the first North American Digital Cellular System. TIA, then formed a new group TR45.3 to develop cellular digital standards for North America. I personally preferred FDMA because it was a low-risk approach due to the fact that the cellular analog system is also FDMA and the equalizer is not needed. Furthermore, with ARTS suggestions of having dual-mode
