Terrestrial microwave relay links are limited in distance to the visual horizon, a few tens of miles or kilometers depending on tower height. Tropospheric scatter ("troposcatter" or "scatter") was a technology developed in the 1950s to allow microwave communication links beyond the horizon, to a range of several hundred kilometers. The ...
Microwave engineering pertains to the study and design of microwave circuits, components, and systems. Fundamental principles are applied to analysis, design and measurement techniques in this field. The short wavelengths involved distinguish this discipline from electronic engineering. This is because there are different interactions with ...
CableFree Fixed Wireless Microwave Backhaul links deployed for mobile operators in the Middle East. These microwave links typically carry a mix of Ethernet /IP, TDM (Nx E1) and SDH traffic to connect sites with high capacity. Such microwave links used to carry 2xE1 (4 Mbit/s) now carry 800 Mbit/s or more, using modern 1024QAM or higher ...
International Journal of RF and Microwave Computer-Aided Engineering is a peer-reviewed scientific journal, covering computer-aided design methodologies for radio-frequency and microwave engineering. Established in 1991 and originally published by Wiley , it was transferred to its subsidiary Hindawi in 2023, adopting an open access model.
RF microwave CAE CAD is computer-aided design (CAD) using computer technology to aid in the design, modeling, and simulation of an RF (Radio Frequency) or microwave product. [ 1 ] [ 2 ] It is a visual and symbol-based method of communication whose conventions are particular to RF/microwave engineering.
This corresponded to the opening of the first new microwave link. By 2013, 15 such links were in operation between the two cities, and similar networks have been started between London and Frankfurt and other locations. Although these do not use the original equipment, and generally do not use the antennas either, the towers are perfectly sited ...
A Goubau line or Sommerfeld–Goubau line, [1] or G-line for short, is a single-wire transmission line used to conduct radio waves at UHF and microwave frequencies. [2] [3] [4] The dielectric coated transmission line was invented by F. Harms [5] in 1907 and George J. E. Goubau [6] in 1950, based on work on surface waves on wires from 1899 by Arnold Sommerfeld.
Radio links can also be digital, or the older analog type, or a hybrid of the two. Even on older all-analog systems, multiple audio and data channels can be sent using subcarriers. Stations that employ an STL usually also have a transmitter/studio link (TSL) to return telemetry information.
