[WISPA] Gas-line broadband a pipe dream?
Gas-line broadband a pipe dream? Posted 9/10/2006 6:22 PM ET BROADBAND BY GAS PIPE How customers can get broadband access through natural gas pipelines, according to Nethercomm: 1. Ultrawideband radio transceiver sends wireless signals through natural gas pipe. The signals would not interfere with gas delivery or present a risk of explosion. 2. Buried pipes are shielded from open-air broadcast interference. Pipes can be metal or plastic; stronger signals are needed for plastic pipes. 3. The signals travel through the pipe at broadband speeds -- up to 6,000 megabits per second. 4. Transceiver takes signals from pipe, decodes the broadband Internet, cable TV and phone content, and sends them to the converter box in the home. Sources: West Technology Research Solutions, Nethercomm NATURAL GAS MARKET SHARE Natural gas market share: West: 75% Midwest: 76% Northeast: 64% South: 42% U.S. total: 62% Source: American Gas Association By Paul Davidson, USA TODAY So intense is the drive to deliver high-speed Internet service to American homes that entrepreneurs have seemingly tapped every conceivable pathway: fiber-optic cable, the air, even power lines. Now the relentless pursuit for faster, cheaper broadband is leading to perhaps the last unclaimed conduit to your house: natural gas pipes. Nethercomm, a San Diego-area start-up, says it has developed technology to send lightning-fast broadband and TV services via wireless signals through the pipes that deliver the fuel used to heat homes and fire up stoves. Gas pipes serve 62% of U.S. households, says the American Gas Association. Broadband in Gas, or BIG, could give consumers a third high-speed option at low costs and speeds that far surpass today's phone and cable offerings. It also could bring fast Internet to unserved rural areas. But, so far, the idea has been met with both excitement and skepticism. It's been a Coke and Pepsi (battle) between cable and phone companies, says Nethercomm founder and CEO Patrick Nunally, 42, a veteran high-tech entrepreneur. We're in a position to come in and provide real competition. More important, Nunally says, the pipes could be used by pay-TV providers to compete with cable and satellite. In fact, he says, Nethercomm and local gas companies would lease the wireless spectrum to any provider for myriad services: cable giants seeking extra bandwidth for their high-definition TV channels, phone companies looking to pare their multibillion-dollar investments in fiber-optic cable, even businesses such as medical providers with high-bandwidth needs. Gas companies, besides earning revenue from leasing their pipes, could use the broadband service to remotely monitor the integrity of their lines and read gas meters. I think there is a general pulse of excitement about the technology among publicly owned gas companies, says Bob Beauregard of the American Public Gas Association, which represents 650 gas providers serving 5 million rural customers. Nunally says he hatched the idea in 2002 while searching for a new TV and broadband artery to the home that didn't require digging up streets. Around the same time, some California utilities were stringing fiber cable through gas lines to offer broadband. But the process was expensive. Nunally says he had a light bulb on the head moment: wireless. Normally, the twists and turns of a gas pipe would cause wireless signals to lose strength. But ultrawideband, a new unlicensed wireless technology, sends out pulses of radio energy across such a wide swath of frequencies that if some data packets are lost, others can easily make it to the home. Also, federal rules that limit the strength of ultrawideband signals don't apply in underground pipes. So, Nunally says, power levels can be boosted to provide each household bandwidth of up to 6 gigabits per second, several times that of a cable provider. Yet power is low enough so that signals can share the pipes with natural gas without starting a fire, he says. A similar initiative, broadband over electric lines, is further along, with services offered in Manassas, Va., and Cincinnati and a rollout planned for Dallas this year. But the electric companies don't offer TV services and incur high costs to bend signals around transformers. Broadband in Gas would require installation of an ultrawideband transmitter that's linked to an Internet backbone or pay-TV facility at a gas company's network hub. A receiver would be placed at a customer's gas meter. Build-out costs are about $200 per household, Nethercomm says. By contrast, broadband over power lines costs about $600 per household, while phone and cable TV networks each cost well over $1,000 per home to build, says West Technology Research Solutions. Broadband in Gas really has the potential to accelerate adoption of these technologies, says George West of West Technology. Yet some say BIG is,
[WISPA] Patent for Invention to Eliminate Wireless Interference
Patent for Invention to Eliminate Wireless Interference TechnoConcepts says that it has filed a patent application for a new invention to cancel unwanted radio signals that interfere with wireless reception. The Adaptive Narrowband Interference Canceller for Broadband Systems is fully software programmable, can be adapted for use in many digital radio receivers, and claims the benefit of a provisional patent filing in September 2005. The airwaves, particularly in urban areas, are crowded with competing wireless transmissions. Often, strong unwanted transmissions interfere with reception by a wireless device. This invention will make it easier for our wireless receiver chip to ignore those interfering transmissions, said Ronald Hickling, Chief Technology Officer of TechnoConcepts. Antonio Turgeon, CEO and Chairman of TechnoConcepts, said: We continue to expand our patent portfolio. Based upon several innovative ideas and methods from Dr. Oleg Panfilov, our Chief Scientific Officer, this patent should help us in our efforts to protect certain aspects of our direct conversion receiver technology. We anticipate that this invention can also be separately applied to improve the reception of conventional digital wireless devices. If we are able to successfully commercialize this new invention, we expect that it will provide the Company with an additional continuing source of licensing revenue. This invention will become an integral part of TechnoConcepts' True Software Radio, a wireless transmitter/receiver chip technology that operates continuously across different frequency bands, controlled entirely by software. As part of the commercialization process, the Company is currently conducting parametric characterization of its first chips designed for base station applications. Completion of the characterization process is expected by October 2006. The Company anticipates then having a preliminary specification sheet that will serve as the baseline for its initial production run, targeted for the first quarter of the 2007 calendar year. http://www.cellular-news.com/story/19250.php --- --- -- WISPA Wireless List: wireless@wispa.org Subscribe/Unsubscribe: http://lists.wispa.org/mailman/listinfo/wireless Archives: http://lists.wispa.org/pipermail/wireless/

They tried to leverage their situation and provide VoIP e911 until they found themselves out of money from the buildout expense. They were bought by an unheard of company back in January. See http://radinfo.blogspot.com/2006/01/intrado-gets-bought.html. Yes - there is. First, where there are no actual 911 addresses or the County/Parish does not have their end set up there is the long/Lat approach that is being used. The right PSAP is still attained and the right address is given. Wrong, the FCC requires the VoIP operator to support e911 regardless of whether it is available. The VoIP operator is not allowed to market services in areas where e911 isn't supported. Well, we are doing much better than that :-) The biggest advantage with us is that once the e911 call is placed it does not travel over SIP trunks or the internet when it hits our NOC as we have dedicated PRIs to handle that traffic and we dump it to that route. This way we are not relying on Level3 in Dallas J but a straight shot to Intrado. Having PRIs doesn't help you with manual administrative processes. Your company is not special; every telecom company has to deal with these issues. You just don't know that you will have to. The e911 price is exactly what's holding the majority back! The majority of the ISPs who want to do VoIP can't handle a $5000.00 set up fee and then a minimum of $300.00 per month starting out with 3 VoIP phone clients! When we talk with other WISPs about VoIP they aren't so much worried about the price. They are worried about their network,

They had 460 million CASH - - someone knows them well and does a lot of business with them! In fact West did not have $460M in cash. Their balance sheet for Q405 (before the transaction) showed just over $34M in cash, which is why the press release stated they would use cash, debt, and a credit line for the acquisition. You can see the effect of the acquisition on their balance sheet now, which shows they have $33M in cash and $736M in debt. Compare that with Vonage, which currently has $597M in cash and $278M in debt. Clearly, Vonage has a stronger balance sheet, but that doesn't mean much in and of itself. Anyway, my point remains the same; Intrado had a problem with their business that gave West the opportunity to buy them. Whether West can make it work remains to be seen. You can try to trash anything, but that does not change the truth of what is going on at Intrado, West Communications or their partners. You can schpill a bunch of crap, but that is not going to change the fact that you are not legal in what you are doing if you aren't providing e911 for your VoIP clients. I haven't trashed anything; just shared facts, which you don't seem to like. Further, you don't need Intrado to provide e911 services. Why? Because Intrado is just buying the e911 trunks from the ILECs anyway. Anyone can purchase a DS1 e911 trunk to each of the selective routers they may need to cover their market area. If you are a WISP, you don't need national e911 coverage; you need local e911 coverage. Think about that... Intrado et all have a business model based on providing e911 services to national over the internet VoIP providers who need national e911 coverage. Why pay for national e911 service when you can get a single DS1 from your local ILEC and be done with it? Now, as far as we are concerned - for any and all that want to sell their VoIP solution (or ours) and not worry about having the FCC breathe down their necks - - I am offering a solution that will allow that at a price that will not send them to the bank or wonder how they are going to manage to pay next months bills due to an outrageous expense where there is no ROI.

It does however share facts about the situation with others who are less informed. You should know that not only have we been selling VoIP service to our customers for over a year now, we also looked at Intrado as a solution. However, we found that Intrado's solution didn't make sense for us and I would argue doesn't make sense for any WISP. As far as providing e911 where there is NO 911 services - - well that says it all. That would be like building a 5 star hotel in the ghetto.

There is simply no way around the FCC's requirement today if e911 service is not available. Vonage et all don't care, but the FCC is pretty clear. I am also unsure what MANUAL administrative processes you are referring too and if you would care to hit me off list with that I will do my darndest to understand. I provided an example of a PSAP requiring that database updates be supplied via fax.

RE: [WISPA] Tower ice buildup
snip Have been looking at www.usedtowers.com but I will need stamped PE drawings for my state so any of those will need to be re-engineered. snip Buyer beware :)~ I have not personally dealt with Mike Landa - but several in our industry have with great pains and loss of $$... If you're looking to go above 120' you really need to look into a RohnSSV or equivelant. Yes - we lost a Trylon during hurricane Rita ! DOH ! - only had 1/2 of the wind loading she was rated for and she folded clean in half ! The ANWireless towers are built using heavier angle John.

No hollow tubes. I like them myself. I have never tried the ANs discussed though. I am guessing it is a good tower if Johnny thinks so. Hey Johnny, did you lose a Trylon during the hurricane? Did you have an AN tower then also or is that what you replaced the Trylon with? :-)I have 2 Trylons in service currently. One of them just went online last week. The Trylons appear to be built very solid to me. I am not a PE but I did stay at a Holiday Inn Express last night! Scriv Mario Pommier wrote: solid rod towers is all I can say. Don't know if Trylon is solid or hollow. Mario [EMAIL PROTECTED] wrote: I have looked at the AN Wireless product line and they look like great towers and are close by in PA, but they don't make anything over 120 feet. I need to get higher than that to ensure LOS to some key areas. I believe my ice question will be answered shortly, the county's communication site coordinator is having one of his engineers send me the requirements. I'm looking for other suggestions for light duty self-support towers or monopoles as close to 200' as possible but below the 200 mark to avoid FCC registration and FAA marking. Have been looking at www.usedtowers.com but I will need stamped PE drawings for my state so any of those will need to be re-engineered. Trylon is appealing because they will supply the engineering drawings and the cost is relatively low. I don't have room for a guyed tower. Suggestions? Patrick PLEASE take a look at www.anwireless.com for tower considerations. Their HD series is much beefier then the Trylon towers. When compared side to side - you'll be pleased.

RE: [WISPA] 300Mbps Wireless
Our Spectra Lites are adaptive timeslots, if thats the right term. If you run the link calc it will give you a Max throughput in either direction: 146.50 114.26 99.9% 0.06 All I can say is make damn sure you set the noise floor, it makes a huge difference with these radios.

I see the Gemini and Spectra have been rebranded as the PTP 400 and PTP 600, respectively. What stupid names! I hope to god they don't screw up the hardware as they're doing to the brand.
