It's called "radio". aka "wireless". The modems/routers/hubs have these funny things called "antennas" on them and so do the boxes out on the utility pole. I had that 10 years ago - it was called Ricochet/Microtel, ran at dial-up speed using the 900 MHz non-licensed spectrum/technology, and worked just great. 24/7 connection with no extra phone line, DSL and Cable Modem service not quite on the market yet, and standards still being debated by several technical groups that I was a member of. Just about five years ago they went broke and stopped offering the service. I still have the device in the original carton (had to look at it to remember the name). I had heard that they tried to revive it at higher speed in the 2.4 GHz Part 15 band, but they aren't offering that service in this area and probably never will, what with everyone using 802.11b LAN access. I undertand that they would use a band of frequencies which would "endanger" our 2.4 Mhz allocations. But like I posted somewhere else earlier, I'll trade 2.4 Mhz for 14 Mhz any day. The 802.11b "Wi-Fi" LAN technology operates at 2.4 GHz, not MHz. The nice part about that is that Wi-Fi Channel 1 (IIRC) falls totally within the portion of the band that is shared between Amateur and Non-Licensed Part 15 users, and (theoretically, at least) a licensed ham can hang a super-high-gain antenna and a power amp on a commnercial Wi-Fi unit (CompUSA "special") operating on that channel, modifications that non-licensed Part 15 users cannot do. Just think what 1500 W TPO would do to the neighborhood Wi-Fi users. DX records. "King of the Hill". Some of them do and that's not good. Others are in the 5 GHz region. 802.11g - "Wide-Area" LAN or WAN. The Bay Area Wireless Communications Alliance members were discussing this about 5 years ago when I was active with that group. A higher-powered version requiring a point-to-multipoint microwave system license was starting to be pitched to a different crowd from the 802.11b (2.4 GHz) users. What is most important is that we can have a protected slice of GHz *and* those technologies can exist. The current show-stopper for the 802.11 crowd seems to be a lack of standards and coordination. Which is very typical of fledgling technologies, These ARE standards. Just different applications. Carl Stevenson is a national and international expert on them. And eventually evolutionary forces will do what they've always done and some 802.11 type system or another will be ready to market on a global scale. Both the 802.11b (short-range) and 802.11g (long-range) systems have been marketed on a global scale for several years. Don't confuse them with the differing standards for cellphoes and color TV - USA vs the rest of the world. BINGO! I knew you'd get it. Just like VHS smacked Beta's rear years ago. What makes you think that Beta died when VHS became the consumer standard? The TV and broadcast industry standardized on Beta for field recording, but alas Sony is no longer supporting it, having had it replaced by digital technology. Look for the same thing to happen with VHS - "everyone" is going to DVDs. -- 73 de K2ASP - Phil Kane From a Clearing in the Silicon Forest Beaverton (Washington County) Oregon |

Which is very typical of fledgling technologies, These ARE standards. Just different applications. Depends on what/how/who defines a "standard". Touch-tone pads are standard. The rest are questionable on that scale, and in the case of the instant topic very questionable. I spend a good bit of time cruising the financial news, London Financial Times, Reuters, Business Week, anywhere where I don't have to cough up coin to get into like the WSJ. The technologies which will matter down the road are those Wall Street buys into. The rest will be orphaned. Good collection of articles by the investments pundits on the likes of Wi-Fi and the related standards problems they see in this field. http://www.businessweek.com/technolo.../tc_04wifi.htm Speaking of orphans . . I have yet to run into a single peep about BPL anywhere in the tech investments rags so far. I think this silently speaks volumes about the future of BPL.

Run the fiber down the street on the poles, put a little box every so many poles, use a little encoding, no problem. Certainly. But running fiber optics lines is a very expensive proposition, much more expensive per unit length than any of the other utility lines. If/when real wideband access comes true in this country it's most likely gonna at least get started via the cable. That probability is mixed into Comcast's move to bring the Mouse to Philly. And if "they" can't find a "solution" then kiss the 2.4 Ghz (got it right that time) ham band 'bye-'bye. Get comfortable with the concept More bandwidth than all of HF. Hare and I touched on that when he was here, it's a classic case of use it or lose it and it's not being used. I asked him how much ham activity he knew about on 2.4 Ghz and he answered "What activity?". btw, I came across some info on the Manassas thing. $20 month for BPL - for the first three months! Then it jumps to $50/month. On a good day it might get up to half of DSL speed. Maybe. Good. I hope they lose their skivvies on that deal. In this country standard DSL runs 0.5-1.0 Mb/s and can be found for $30/month. Cable here runs at around 3Mb/s for $45/month. The JAs have a flavor of DSL which runs at 26 Mb/sec in heavily-populated areas for $50/month with the HLs close behind. Manassas BPL for $50/month for only half of 0.5-1.0 Mb/s you say? They gotta be kidding . . ! One more dot bomb in the making . . At this point I'm not in the least bit convinced that Gore would have been one bit worse that the Shrub. Izzat the sun coming up over Sugartown Road? Huh? How did Sugartown Rd. get into it?? Have you checked the size of the national debt recently? Yep. But that's not the big problem - the real 800 pound gorilla is how fast the deficit is making it grow. A few years back we had a surplus.... Yeah, it's the rate which is really scary. And now we're supposed to go back to the Moon, and send people to Mars. Yet the odds on a Shuttle failure are worse than 100 to 1... I don't see shuttle safety being part of the politics of the upcoming campaign. As has been the case in all major explorations since Leif Ericsson's days and millenia before the folk who ride the things know they didn't buy a seat in a 737 and some are not gonna come back. Tell ya what, let's fund Shrub's moon-mars-madness the same way things like education, mass transit and health care get funded. How 'bout we just bag the whole stupid Mars camping trip thing and first build a new version of the Shuttle then put Wideband on the front burner as a matter of national policy? Which is what the JAs and HLs did and explains why this country is years behind them in this field. We could have walkathons and bake sales. Corporate sponsorship in return for advertising space, just like they do in NASCAR and at Indy. Let groups and individuals send in money to buy parts and supplies - a gallon of rocket fuel, coupla resistors for the computer, etc. NASA can have anything in the Southgate Radio stockroom for a very nominal price. Let's not get carried away here Miccolis . . 73 de Jim, N2EY w3rv |

It's already all over the place out here in the Principality of Radnor. And TE, and West Chester, etc. There's an optics cable running along the street here which isn't more than 75 feet from me as I peck at the keyboard. And a half block north there's a moose-sized optics cable running along MacDade Blvd. I have no idea where they come from or where they go or what they actually do but there isn't a drop to a residence or a business in sight anywhere. I've seen Ma Bell "mobile labs" futzing with the things so I guess it's for running phone comms between switching centers. Or something. In any event these cables don't look like they're ready to duke it out with BPL. The really big cost is getting from the pole into people's houses. That's the really big selling point of BPL: no installation, every outlet in your house is a broadband connection. As if. A lot of "cable" is actually fiber. But it makes no real difference; the big probelm is getting into every overpriced little box made out of ticky tacky. The cable and telco folks took their pain upfront. And they can avoid more pain by *not* installing residential drops. Install 802 dot somthing boxes on the poles every hundred yards or so. Would work and would kick BPLs butt. The huge advantage wireless devices bring to this game is that they do *not* need a connection to the house wiring. Freely floating lappers, remotes, etc. Hare and I touched on that when he was here, it's a classic case of use it or lose it and it's not being used. I asked him how much ham activity he knew about on 2.4 Ghz and he answered "What activity?". I wuz there. And what activity does exist uses highly directional antennas.... Seems like we all forgot that most of it is satellite ops which do not always use directional antennas. That could be a problem but a couple MHZ wide AMSAT setaside would probably work. btw, I came across some info on the Manassas thing. $20 month for BPL - for the first three months! Then it jumps to $50/month. On a good day it might get up to half of DSL speed. Maybe. Good. I hope they lose their skivvies on that deal. They'll ask Uncle Sam to bail them out. "No millionaire left behind". That would require Congessional action and it would never in this world happen. Didja see where RCN went Chapter 11? I looked at RCN when it first popped up. Talk about no bang for the buck, the Comcast and Ma Bell guys musta been laughing their buns off at the RCN prices. The cofounder of Microsoft put 1.65 billion into that outfit and now his piece is worth $2 million. That's like putting $165,000 of yer IRA/401K in something and having it go down to $200. Yeah and after RCN drubbed him Mr. Allen came out with 20 point somthing billion left in his piggy bank. Pore thing. He and his buddy Bill are tossing coin at all sortsa wild investment adventures. Their baby airliner is a good example. They don't care, it's only money. Cable here runs at around 3Mb/s for $45/month. The JAs have a flavor of DSL which runs at 26 Mb/sec in heavily-populated areas for $50/month with the HLs close behind. Manassas BPL for $50/month for only half of 0.5-1.0 Mb/s you say? Double check with Ed but I recall half MB as the best they'd ever gotten - and that was for a single customer on the system. More folks = sharing. . . . . more is better, bring it on . . . They gotta be kidding . . ! One more dot bomb in the making . . I sure hope so. Boom dot bust. But it ain't over till it's over. It won't hurt very long . . Yep. But that's not the big problem - the real 800 pound gorilla is how fast the deficit is making it grow. A few years back we had a surplus.... Yeah, it's the rate which is really scary. Not just a big hole but digging it deeper as fast as they can. Check OMB's rant on the subject which was published yesterday. I don't see shuttle safety being part of the politics of the upcoming campaign. As has been the case in all major explorations since Leif Ericsson's days and millenia before the folk who ride the things know they didn't buy a seat in a 737 and some are not gonna come back. That's not how it was sold, though. Ask the McAuliffes if they were told that there was a 1 in 75 chance of augering in. Sure they knew, just like the relatives of military aircrews know the level of risk involved. Whether they accept it and internalize it or not is another story. How 'bout we just bag the whole stupid Mars camping trip thing and first build a new version of the Shuttle then put Wideband on the front burner as a matter of national policy? That makes way too much sense. In fact the really sensible thing would be a cheap oneshot big booster for unmanned payloads and a highly reliable but much smaller human transport system. Send the big stuff on ahead and the astronauts meet it up there. The UAs been doing that for thirty years. Hey - didja see where they're planning a space walk on the ISS where all the crew will be outside at the same time, with nobody in the station? Didn't they ever go to the movies back in 1968? Was not the first time by any means and yup, it rained so they had to duck back inside. 73 de Jim, N2EY w3rv |
