Microwave Components & RF Propagation | Duration: 1 hour | Tuesday, October 13, 2020, 01:00 PM Eastern Daylight Time
Speakers: Comsearch’s Joe Marzin (Technology Group Director) and Eric Nielsen (Sales Relationship Management Specialist)
Summary: This webinar covers RF propagation concepts for the transmission of a microwave signal from one endpoint to another. The behavior of the signal is broken down into various concepts of path loss to include free space path loss, atmospheric absorption, diffraction, and refraction. The concepts of diffraction and refraction lead to the development of the parameters Fresnel Zone and K-factor, or effective earth radius factor. These are key components in the evaluation of microwave path clearance. These key concepts and parameters help to understand path design criteria and fading characteristics of microwave paths.
Path Reliability & Path Design Considerations | Duration: 1 hour | Tuesday, November 10, 2020, 01:00 PM Eastern Standard Time
Speakers: Comsearch’s Rhett Butler (Engineering Manager) and Eric Nielsen (Sales Relationship Management Specialist)
Summary: This presentation will provide an understanding of microwave path reliability and how factors such as antenna size, radio transmit power, terrain, path length, rain, climate can affect the overall availability. Strategies for designing microwave paths to overcome common problems including multipath and rain will also be offered.
Interference Analysis & Frequency Planning | Duration: 1 hour | Tuesday, December 08, 2020, 01:00 PM Eastern Standard Time
Speakers: Comsearch’s Tim Rockett (Frequency Planning Manager) and Eric Nielsen (Sales Relationship Management Specialist)
Summary: Interference Analysis — Sources of potential interference, from both point to point and earth station operators | The calculation of both C/I actual values and C/I objectives. Frequency Planning — Establishment of high/low plans at sites and “bucking” | Analysis results and mitigations techniques, to include polarization and frequency offset, terrain blockage, ATPC, growth channel relinquishment and antenna upgrades | Regulatory warnings, ASR location issues and legacy call sign data synchronization.
