دانلود کتاب Wireless Spectrum Finder: Telecommunications, Government and Scientific Radio Frequency Allocations in the US 30 MHz - 300 GHz

توضیحاتی در مورد کتاب به زبان اصلی :

Today's airwaves are prime real estate for anyone selling telecom services. But the public frequencies are not for sale; they are allocated, licensed and regulated by the FCC. Therefore, if your business offers a service that goes out over the airwaves, you'll need engineers, lawyers, license consultants and developers with expertise in "spectrum planning". Informed spectrum planning is the only way to ensure you'll get access to the bands that transmit what you sell, and to guarantee that products you market will be compatible with technology used by your customers. Despite the fact that spectrum planning is baseline information for today's hottest businesses, it remains an esoteric field. All data are in the public domain and available on the Web, but they are widely scattered, often out of date, sometimes contradictory, and written in Federalese. This book cuts through the confusion and deliberate obfuscation to make spectrum planning a much more intuitive exercise. There are 368 bands in the public spectrum, although not all of them have been commercialized yet. For each band, this reference provides the following hard data: scientific definition; allowable uses; licensees and term of license; and applicable regulations in the US and elsewhere. In addition SpectrumGuide offers interpretive aids for each band covered: footnotes on usage from government, international and other sources; business, legal and technical trends analysis affecting the band; pending legislation and issues before the FCC; effective dates of new legislation; and a policy statement from the trade organization or government agency representing users of the band.
