 Back in March we made a post introducing the FCC Spectrum Dashboard which at the time was being beta tested. Now the site has been upgraded and officially taken out of beta! The dashboard adds a sense of transparency into how America’s spectrum is being used. In the FCC’s words: “The Spectrum Dashboard allows new [...]  It’s not been the Curmudgeon’s intention to devote appreciable coverage to the Amateur Radio Service (ARS) in these blog postings. A majority (perhaps most) of today’s telecommunications professionals are no longer licensed hams, although in past decades they most likely would have been. However, two recent personal events again brought the ARS into focus. In the first, earlier this year the Curmudgeon (today an Amateur Extra Class licensee) celebrated the fiftieth anniversary of earning his first ARS license, which was the (former entry-level) Novice class ticket. The second event was receipt of a gift of some computer CD-ROMS containing sets of page image files for the historic 1930 through 1959 issues of QST Magazine (the principal ham journal, published by the American Radio Relay League). [...] The US economy, juiced by the national popular culture, is about to commit another major telecommunications blunder! The title of this piece gives a clue to it. Since there is no way to stop or to prevent the developing blunder, it might be of some use at least to understand what we are doing. American [...]  The FCC requires that all 2600 MHz band BRS and EBS broadband licensees who would must demonstrate that they provide “substantial service” to actual customers no later than May 1, 2011. Failure to meet this requirement will result in forfeiture of the license and the licensee will be ineligible to regain it. Various “safe harbors” [...]  The Spectrum Dashboard pulls from the FCC’s license databases and lets anyone browse the allocations table for licensed spectrum. Users can search FCC license records using a map interface, or search the records by common name – Verizon, for example – which greatly simplifies pulling together data by carrier. Determining who has radio frequency licenses in a given metropolitan area suddenly is [...]  Through collaboration between Artech House publishers and the IEEE Communications Society, a free web tutorial has been made available to wireless engineers. The tutorial will address a number of autonomous and intelligent techniques which can be applied to emerging high bandwidth systems to realize spectrum and network efficiency. It will address smart and effective design, [...]  There’s so much heat on in the spectrum and broadband areas today, LBA asked the Curmudgeon to expand a bit on his last posting’s spectrum musings. In the last blog post we identified the looming potential problem of total consumption of the radio frequency spectrum. If we want to head this off, we need to [...] LBA asks the Old RF Curmudgeon to put on his magic glasses and look through the swirling mists of spectrum policy. In this several part (he’s still looking) series the Curmudgeon will share with us the fantastic visions of spectrum usage and policy that he tunes in. Look with him carefully, as the spectrum path [...] LBA asks the Old RF Curmudgeon how “being wired-in continuously” on hand held RF devices is affecting the (still) finite RF spectrum. The Curmudgeon believes that, without necessary and sufficient prior consideration, the US is starting down a technological path which may well prove to be unfortunate, festooned with many unforeseen consequences. One wishes that [...] LBA asks: What do you think of the future of AM broadcasting as you see it today? This one is emotional, of course. After all, AM radio is one of the very oldest uses of the radio spectrum (beginning ~1919), as evidenced in part by the Medium Frequency band on which it began and still [...] Radio frequency test equipment now offered by LBA includes instruments for digital TV, radio, wireless, CATV, satellite and laboratory use. The supply of this equipment in the Americas through LBA is fully supported by the entire Kathrein – Schomandl team! Read more [...] LBA asks: There has been a lot of activity recently among FM broadcasters, what with adding IBOC digital, more transmitting power and station upgrades for better coverage. Knowing your “RF sensitivity”, where is all this going for our spectrum? One day not too long ago I happened to have my spectrum analyzer connected to the outside [...] *** If you are new to The Old Curmudgeon series, read the previous blog for a brief introduction.*** LBA asks – “Well, RF Curmudgeon, what do you say to this RF interference and spectrum pollution from the nifty LED devices popping up everywhere? Why I can’t drive through an intersection without LED traffic lights blanking [...] From what I have been able to observe, the “driver” for establishing the new data service may have come directly from the White House. There it may be the case that some big-hitter campaign contributors got to the administration, or it may be the case that they were convinced by “experts” that BPL was the [...] |
