 We have now finished reviewing the dismal (partial) list of historic FCC spectrum management engineering mistakes, and in this final part of the series we’ll look at some suggestions for how the FCC could, ideally, conduct this highly-important function. The Commission would never adopt any of these proposals, of course, but “even engineers can dream!” [...] In this post we will finish the list of FCC historic spectrum management mistakes that began with Part 1 of this series. 12. Land Mobile “Re-farming:” (1990s-present). By itself not a major league blunder, but more of a “wolf in sheep’s clothing” gambit. The basic idea is to halve, and then later halve again, the [...]  Just three decades after the first generation of wireless telephone technology was introduced, engineers, wireless operators, and industry analysts are talking about the best way to split the fourth generation broadband spectrum into more usable parts. It could get messy, LBA Group’s Chris Horne warns. Horne’s warning came in a discussion at last week’s 4G [...] The Curmudgeon recently read an account of yet another potential spectrum management (engineering) gaffe toward which the FCC has been briskly marching, and that set him to pondering. The FCC has, historically, produced a series of what might be classified as spectrum management mistakes, ranging from blunders at the marginally tolerable level to complete fiascos. [...]  Two RF safety experts from LBA Group, Inc. will teach radio frequency safety to company managers in a class in Texas. The class sponsor is ComTrain, which provides safety training for the vertical structure construction industry. It sought LBA’s expertise. “Basic Tower Construction Class” is Sept. 19-23 at ComTrain headquarters in Austin. LBA will present [...]  Chris Horne, LBA Group, Inc. CTO, will be moderating a free webinar on PIM: Passive Intermodulation sponsored by the WCAI Engineering committee. The speaker will be Ray Butler, Vice President – Base Station Antenna Products and Development at CommScope. PIM has become increasingly important with the explosion of wireless data services and the increasing need [...] In this series we have been looking at the telecommunications technology available to the average consumer in the year 1960 and comparing it with what exists today. In this concluding post we will summarize what has been presented and draw some (personal) conclusions. Summary: It should be somewhat apparent to the reader of these past [...]  Global Positioning System receivers remain wary of the plan by 4G network provider LightSquared to create a wireless broadband network to serve every nook and cranny of the U.S. In testimony June 23 before a House subcommittee, opponents of the LightSquared system said it would endanger the GPS navigation systems that aircraft and ships depend [...]  Many radio and TV broadcasters in the United States are not aware that a year’s old FCC rule may be about to wreck their microwave operations! If you have an affected operation, you should take immediate action to preserve interference protection for your system. On October 16, 2004 the FCC changed the coordination rules for [...] In this series of posts we are looking at the telecommunications technology available to the average consumer in the year 1960 and comparing it with what exists today. We will perhaps be able to see some of the changes in daily life that the technological advances of the past fifty years have brought, as a [...] In this series of posts we are looking at the telecommunications technology available to the average consumer in the year 1960 and comparing it with that which exists today. We can trace some of the changes in daily life that the technological advances of the past fifty years have brought, and also see how our [...] In this series of posts we are looking at the telecommunications technology available to the average consumer in the year 1960 and comparing it with what exists today. We will perhaps be able to see some of the changes in daily life that the technological advances of the past fifty years have brought, as a [...] Last time we began a discussion about some of the factors (mostly human-created) which could limit the future usability of the RF spectrum. The first two were spectrum-use saturation and the spread of poorly-designed, RF-radiating digital devices. In this post we’ll conclude the Curmudgeon’s list with three more possible factors, and then toss it open [...] The recent series of posts dealing, in part, with the future of the Amateur Radio Service launched the Curmudgeon’s thinking into a new direction. Being a “philosopher dude” kind of guy whose thoughts tend to move toward larger and more futuristic issues, the Curmudgeon generalized his thinking to consider the future prospects for the entire [...] There is an article in the October 2010 issue of IEEE Spectrum (p. 26), “The Great Spectrum Famine.” It makes much the same case as does the Curmudgeon, but from more general considerations and a bit higher level. The Curmudgeon said: “It really doesn’t say much that we don’t already know, and I don’t really [...] This is a tale of two cities and a case of monumentally stupid broadcast regulation by the FCC that has afflicted their region of the country. The story in Part I will make a small point, but one which has larger ramifications that will be developed in Part II. The Curmudgeon lives in a mid-sized [...] In this final part of the series, the Curmudgeon looks backwards (with just a little nostalgia) at the ARS of fifty years ago as a reference point for today’s Service and notes that, even then, it was not a perfect society. And he gazes into a well-clouded crystal ball and hazards a few guesses about its future. [...] In the previous post, the Curmudgeon looked at the first of the two major sociological changes that, in his opinion, have occurred in the Amateur Radio Service during the past fifty years: the “dumbing down” and “consumerization” of the ARS. In this post he examines the second major change. This other change, the Curmudgeon suggests, is the ascendency of ARS operators’ ego as a principal organizing force. It has changed the Service during the past half-century, and not for the better. There are several ways in which this trend manifests itself today. [...]  We reported in a previous post on the zombie satellite Galaxy 15 that went rogue on April 5th about the potential interference this “zombie satellite” could cause, at the time with AMC 11. This time, roughly 35,000 people in rural Alaska may experience problems caused by the zombie satellite. They may lose Internet access, long-distance phone service or both for periods of 90 minutes to as long as 5.5 hours between Wednesday August 11th and Saturday August 14th. [...] 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). [...]  Comments are now closed on the FCC Notice of Proposed Rulemaking (NPRM) to overhaul antenna-related rules, which covers Part 17 on construction, lighting, and marking. Comments were due by July 20th and the deadline for replies is August 19th. A lot of our readers and clients already own AM broadcast antennas or if you own any kind of antenna structure or are expecting to build one, hopefully you have already contacted the FCC and made your suggestions, as this opportunity does not come along often. [...] 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 [...]  Apparently believing the old Brylcreem advertising slogan “A Little Dab’ll Do Ya,” Canadian proponents of the digital audio broadcasting (DAB) technology relied on a few stations in major markets across the country to spread the word. It didn’t work. The Canadian Broadcast Corp. has announced it is shutting down DAB digital transmitters in Montreal, a [...] Within the developing utility Smart Grid universe, this time we’ll look at some special concerns about the customer-centric Advanced Metering Initiative area. Here the deck is stacked entirely against the consumer. First, the consumer will have to pay the costs for implementing the Initiative; in California alone, the costs just for replacing a significant portion [...] Last time we introduced the new buzzword term, the utility Smart Grid, provided a quick overview of the concept-undergoing-creation, and noted that doubts exist whether the utility industry can successfully implement it. Now let’s spend a little time examining those doubts as they relate to the utility-centric side of the Smart Grid effort. The first [...] There is a new “next great thing” concept now moving through the land, undergoing promotion in the popular press and probably destined to be a future concern (and cost burden) to the citizens of the United States. That term is “Smart Grid.” And it’s a term that would be much easier to deal with if, [...] The Galaxy 15 satellite that was knocked out by a solar storm on April 5th (but is somehow still transmitting) has been slowly drifting towards the AMC 11 satellite and was expected to drift into the orbit of AMC 11 around May 23rd. Since these 2 satellites operate on the same frequencies, there was expected [...]  Some wildlife conservationists and communications industry members have reached an understanding about how to start giving migrating birds safer flights when they take wing in the vicinity of wireless and broadcast towers. In a memorandum submitted this month (May) to the Federal Communications Commission, the ad hoc group recommended the FCC develop interim standards on [...]  Engineering consultant Richard Arsenault says the biggest problem for AM reception during the daytime “is no longer interference between stations”, as it was when the AM service was established decades ago. The former station owner and consulting engineer says the threat is now “interference from electronic devices and power lines”, and it’s steadily getting worse. [...]  Cisco recently performed an on-line survey about RF interference and Wi-Fi network usage with 600 participants from industries such as agriculture, education, arts, manufacturing, retail, healthcare, and many others. 78% of companies now consider all or part of their wireless network to be mission critical. 54% of companies indicated that RF interference causes wireless network [...] |
