Many digital radio-relay routes use radio-frequency channel arrangements originally designed to accommodate analog radio-relay systems.
A paper giving the results of h.v. measurements made on needle gaps, wire gaps or parallel wires, sphere gaps, air capacitors and insulators, carried out at 13 000 kc./s.
The number of microwave systems that may he used on a particular frequency assignment in a given area is determined by the mutual interference between the systems.
This study investigates potential applicability of LoRa technology in power distribution and monitoring. A testbed has been set up at Dudullu Industrial Zone as a pilot study.
After World War One, in October 1922 the Austrian federal government decided to privatize the domestic radio activities to provide a commercial oriented entertainment broadcasting service.
In the radio operating room there are two positions for short waves and broadcasting, one for medium-wave telegraphy and one for long-wave telegraphy.
We present a map of the sup 12 CO (1-0) emission from the region around Zeta Oph at high spectral resolution and high signal to noise, and report a detection of sup 13 CO along the line of sight t
With the wide availability of broadband Internet access driving upwards the bandwidth needs of network applications, at the same time as users increasingly shift towards mobile devices and on-the-r
The analog modulation performance of a high-power two-electrode tapered laser is investigated.
The power radiated from a transmitting antenna is ordinarily spread over a relatively large area.
