Transcription

1 2013 * This course is intended for Transmission Planning Engineers, Microwave Support Technicians, Project Managers, System Installation, test personal and Path design Engineers. This course give detail insight about all the aspects related to Microwave Planning for wireless networks. It includes but not limited to SDH, PDH, RF Channel capacity, link budget concepts, propagation, fading, interference and radio link commissioning. *Formally known as Microwave Transmission & Link Planning Engineering & Technology Solutions info@etspk.com, 2/24/2013

2 Course Overview This intensive microwave link planning course discusses the microwave wave propagation in depth and meaning of equipment parameters that determine the performance of a radio-relay path. The formulas used in link planning and methods to predict both performance and unavailability are described in depth, both for the radio hop and for the radio circuit (or link). During this course, a great number of examples are used to make it easier for the course participants to understand the steps and formulas involved in end to end microwave transmissions network planning. The course begins with the basics of radio system design and analysis, addressing operating frequency, available spectrum, channel bandwidth, modulation schemes, radio access techniques, basic and advanced antenna systems, using equipment specifications in link budget analysis, and performing path loss analysis based on the type of propagation environment and signal distortions caused by time displacement of radio signals in non-line-of-sight environments. Course Objectives ETSI Digital Signal Hierarchy for customer payload signal types and the relationship to microwave radio interfaces Signal flow through a radio terminal Transmission line basics and the passive components used in typical radio terminal designs Customer traffic loss protection hardware vs. propagation failures ETSI RF channel sizes in frequency bands, link capacity and the tradeoffs of each modulation type Radio link budget basics, signal propagation basics, and technologies used in radio to increase availability High level radio link commissioning / testing of PDH, SONET and Ethernet traffic Troubleshooting techniques Who Should Attend?
