In order for direct wave communication to occur, antennas at both ends of the path have to have low angles of radiation so they can see each other. Some ground wave communication is possible on 80m, but at frequencies above 5 MHz, the ground wave is irrelevant. It has daily and seasonal variation, as well as a much longer 11 year cycle.
Radio Wave Propagation - PowerPoint PPT Presentation The only MF amateur band, m, will not be discussed, nor will bands above 10 meters. Products Sold on our sister site CrystalGraphics. It is a paradigm shift in student-centric, online education.Toggle navigation. Virtual labs are any place, any pace, any-time, any-type labs. Training and skill-set augmentation through workshops and on-site/ online training.Access to online labs as a complementary facility to those colleges that already have labs.Access to online labs to those engineering colleges that lack these lab facilities.Specifically, the Virtual Labs project addresses the following: Internet-based experimentation further permits use of additional web-resources, video-lectures, animated demonstrations and self-evaluation.
This student-centric approach facilitates the absorption of basic and advanced concepts through simulation-based experimentation. Yet another objective is to arouse the curiosity of the students and permit them to learn at their own pace. The Virtual Labs project addresses this issue of lack of good lab facilities, as well as trained teachers, by providing remote-access to simulation-based Labs in various disciplines of science and engineering. Also, good teachers are always a scarce resource. Paucity of lab facilities often make it difficult to conduct experiments. Good lab facilities and updated lab experiments are critical for any engineering college.
