목차/설명	Take the guesswork out of land-mobile radio system coverage prediction with this unique book and software package. Taking you beyond mere descriptions of system aspects such as propagation, modulation, coding, and frequency re-use, it addresses how to use this information to accurately predict, verify, and measure radio system coverage. If youre responsible for specifying the site layouts of conventional or cellular land-mobile radio systems, youll find the information in this book compelling. Clearly written and concise, it shows you how to handle both Rayleigh fading and lognormal shadowing in coverage prediction, and how to estimate signal strengths and bit-error probability. You also learn how to implement acceptance procedures that help you decide whether your test plan will be cost efficient. Supplemented with more than 50 examples of real-world radio system coverage problems, the book also suggests how system coverage procedures will evolve in the coming years. Other well-structured chapters detail... Expressions for area coverage Models for median path loss Relations for the ratio of desired to undesired signal level How to tabulate gains and losses to establish communications distance -------------------------------------------------------------------------------- Contents: 1.
