 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 [...]  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 [...]  Recent legal cases between some wireless carriers and manufacturers of signal boosters also known as handset amplifiers have moved the FCC to issue a Notice of Proposed Rulemaking (NPRM) to address interference concerns by the mobile operator. The FCC initiated the proceeding to “facilitate the development and deployment of well-designed signal boosters” In the proceeding, [...] “Whatever happened to HF radio?” (No, not HD radio, HF radio!). “High Frequency” radio flourished back in the days before “radio” became “wireless,” when perhaps it was better known as “shortwave radio!” And if you are old enough, the term “shortwave” can still conjure up some half-forgotten memories. Of crackling news broadcasts from far away [...] 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 [...] Last time we looked at the consequences of a broadcast channel allocation matter in which a small, analog Low Power TV station was displaced from its high UHF channel assignment in Pleasantville (a medium-size city located near Gotham City, a regional metropolis) by the FCC’s re-allocation of its existing LPTV channel to the new 700 [...] 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 [...] |
