Summary "This practical book provides design and implementation guidelines for LOS (Line of Sight) Microwave Radio Links, which are a technological necessity in the telecommunications industry, offering readers ample case studies and ways to apply and adhere to industry standards. The coverage describes the procedure for designing a frequency plan and a channel arrangement structure according to ITU current standards with specific application examples. Analytical examples illustrate the specifics of calculations and provide order of magnitude for parameters and design factors for students approaching the topic for the first time"--Provided by publisher
