To answer that, we need to be specific about each aspect of CBRS. In the spectrum domain, CBRS must carefully participate in spectrum sharing, as there are other users of the same frequencies. These users are g
In analog modulation, some aspect of the carrier is varied in a continuous fashion. The oldest form of analog modulation is amplitude modulation (AM), which is still used in radio broadcasting at some frequencies. Digital modulation predates AM; the earliest form was Morse code. Modern telecommun...
Spectrum efficiency refers to the use of a radio frequency spectrum in more efficient ways. The wireless spectrum or wireless frequency spectrum is the set of radio frequencies used for wireless devices. Each specific type of radio frequency use has its own frequency bands available within a comple...
A coaxial antenna is a type of dipole antenna used with an unbalanced feed line connected to the device. A coaxial antenna has a hollow conducting tube through which a coaxial cable passes. Coaxial antennas are mostly used with citizens band (CB) radio at frequencies above 10 megahertz. Coaxia...
What are the wavelength ranges in (a) the AM radio band (540−1600 kHz) and (b) the FM radio band (88−108 MHz)? Frequency and Wavelength Both frequency and wavelength can be expressed using the equation f=cλ, where c=3.0×108 ms is t...
radio emissions produced from electrons spinning in magnetic fields provide information on the formation and evolution of the cosmic web across time and space while low radio frequencies uncover oldremnant sources. Whether magnetic, electric, or gravitational, the Universe is full of vibrational signals...
Boost Mobile’s new 5G unlimited plans are here, and they’re cheap T-Mobile just made its 5G Home Internet plan cheaper; here’s the new price However, for 5G to deliver on its promise, it also needs to break new ground in the radio spectrum, using frequencies that have never before...
For instance, there are 2 basic types of coax cable in use in amateur operations. Go to the RadioWorks catalog page 62. You will see the 3 types to the left are about 1/4 inch in diameter and the others are about 0.4 inch. If you look at the table below the cable types, you wi...
Well, to make a long story short, when a new communications protocol is to be launched there are certainly some requirements that need to be fulfilled to make it compatible with long established amateur radio standards. In my opinion WSJT/JT65 is not in all ways complying with these standards...
lower frequencies than classical music), so one pair of headphones might not sound equally good for everything you listen to. If you're going to go by online reviews, read widely and critically, and check well-informed professional reviews on audio sites as well as off-the-cuff amateur ...
