FCC Approves 802.11b Phased Array
n6zfx writes "802.11b Networking News is reporting that vivato received FCC approval for the 802.11b AP that has a range of 4 miles... This was discussed recently here on slashdot -- There were comments that it might not be totally legal. Hopefully, this paves the way for more WISPs, bigger hotspots, and replacement of outdated wireless technology that seemed to be the only competitor to DSL and tv-cable for the last mile."
Sorry
With a long range like that I guess your brain will be pretty fried if you sit close to the AP, no?

TO THE RESCUE!
:) These are girls without e-mail listed obviously....many are realizing the importance of e-mail, but they have a hard time justifying the cost since they are not 100% sure that they will have mail to read.
Q. How are you different from the other agencies?
A. The reason this service was started was because I simply was dissatisfied by efforts of the other foreign dating services. If you look at the typical dating service, their girls are from all over the Philippines. The Philippines covers a very large area and consists of over 7000 islands. It is unrealistic to think that you will have an opportunity to meet multiple girls due to the fact that it can take as many as two solid days of travel once you get off the plane in Manila to meet a girl in a distant province. And with up to two days of travel on your journey back, you have likely spent as much as four days, and possibly half of your vacation, on a bus or a boat. I had purchased 50 addresses from an agency and upon doing research on the Philippines, I realized that 90% of those addresses were potentially worthless due to inaccessibility. This would especially be the case if one girl was from Luzon and another from Mindanao (the two largest major islands). I didn't have more than 8 days for my vacation and I wanted to meet more than one girl. And since there are many things you must do, like meet her family which takes even more time to accomplish, I knew that I would drastically have to narrow my choices. This left me with 5 girls. I was fortunate that four of the five replied to me. I eventually was able to meet with two of those girls, but I realize now that my money was wasted by those unusable addresses and because my choices were very limited. Because of this, I realized that the foreign introduction industry was severely lacking in its convenience factors. I have set out to create my own custom agency that recruits all of its ladies from the easily accessible and very modern areas such as Manila, Quezon, Baguio City, and Laoag City from the Luzon island. I also realized the much greater demand for these ladies after talking to many of them over a long period of time, and comparing them with ladies from the distant provinces.
Q. Why should you chose the larger cities over the provinces?
A. My personal opinion is the compatibility and convenience factor. If you found this site, it probably means that you are a modern, forward-thinking gentleman. It is in your best interests therefore to choose a lady who, while feminine and conservative, is able to adjust to your habits and culture with relative ease. Typically in the cities, the girls tend to emulate their American and Canadian counterparts with respect to their interests and sophistication. Most, if not all, have cell phones, use e-mail, and are fluent in English. If you have ever written a letter abroad you can expect to have to wait up to two months for a reply. This makes e-mail the only realistic alternative. These ladies are very fashion conscious and try to keep up on current events and popular culture. Most are huge fans of American films and music and love anything that is different from their traditional native culture. They are also fascinated with foreign men in general. If you ever walk the streets of Manila, you will understand what I mean. For example, if you are sitting outside at a cafe, people will slow their pace and stare at you while they walk by. Often they will approach you and ask if you are enjoying your stay and if you like their country and its people. In contrast to the cities, most foreigners tend to experience culture shock when they visit ladies in the distant provinces. While friendly, the people tend to struggle with English and communication is always a challenge. The attitudes about everyday living are also much different than with what we are accustomed. Amenities are scarce. It is almost impossible to find a public restroom in these areas and you must typically resort to having to relieve yourself in the bushes. But if "roughing it" is for you, then maybe the provinces would suit your tastes. Also travel is difficult where you must take a motorcycle or a jeepney for very long distances to complete your trip. There is nothing more frustrating than getting temporarily lost in the provinces. It has happened to me twice, and it was enough for me to pledge my loyalty to the big cities and I am content with what I have found there.
Q. How do you recommend that I go about writing to these ladies?
A. Men who utilize this website tend to focus on girls who have e-mail listed. I must emphasize that just because they do not list an e-mail address does not mean that they cannot or will not use e-mail. Think of it this way: Would you use e-mail and/or pay the fees of an internet cafe if you didn't know anyone else who uses it? Of course you wouldn't. And it is the same for these ladies. They just need a reason to start, and then they will be checking it regularly when they know, for sure, that there will be mail waiting for them, thus not wasting their money.
Therefore I recommend a mixture of girls...write to a few with e-mail and a few that do not have e-mail. Your results will be alot better than if you only wrote to those with e-mail, as they get the most replies. Yes, it will initially take a couple of weeks longer to start your correspondence, but once you have initiated contact, the rate of your communication will increase rapidly as her interest builds. Many girls have even asked why nobody has written yet to our staff in the Philippines. When they are told that it is because they don't have e-mail, they sigh and say how they would use it, but they can't afford to keep paying for something if they are not getting anything out of it. It's up to you to give them a reason. Many filipias actually have e-mail, but they don't want to give it out until they receive an actual letter. They use the written letter as a test of the sincerity of a man. Even though it is clearly stated here about the benefits of taking the time to write, most men will STILL opt for girls who already have an e-mail address available. For those who are reading this, use this "inside" information to your advantage. Also, please make sure to enclose a photo of yourself. It is only fair that if you know what she looks like, she should be able to see your face as well. Finally, make the letter descriptive , honest, and be sure to tell her about your family. Most importantly, do not boast of your accomplishments...it will only turn her off. In other words, be yourself and be humble. They don't want an arrogant and macho attitude....they have seen plenty living from their own areas.
Q. What about calling them on the telephone?
A. I don't recommend contacting them by phone until you have established contact through either a letter or e-mail. Just like you probably don't like it when someone calls to try to sell you something over the phone, these girls are not going to be comfortable talking to a complete stranger (and in a personal manner) that they know nothing about.
Q. How many girls should I write?
A. The minimum number that I recommend is 10. That is why our rates are set up as they are....so that you will be persuaded to choose a healthy number of ladies with which to correspond. A man who is truly sincere about meeting a filipina would be best suited for a membership of some sort. We currently have three different membership options which gives all of the addresses in our database (hundreds) plus all additional updates for a period of time, depending on which option you choose. And the number of available ladies greatly outnumbers the number of members that we have. I am positive that you will be very busy for a long time....and will not be disappointed with your results.
Those men who are disappointed typically only write to 1-3 ladies. Remember that this, like anything else dealing with relationships, is a numbers game. Chances are that there is a lady in our pages that complements you perfectly. You just have to find her. This brings me back to a guy that I used to know back in college. He was just an average looking guy. But he was very aggressive when it came to women. Most of the time, he was rejected outright. But due to his persistence, he was never without a desirable girlfriend. And my other friends could only scratch their heads in disbelief of his success. So hopefully you see that it is much to your advantage to put forth the effort to write to multiple ladies.
Q. What about age differences?
A. Realistically, most filipinas will accept a man who is as many as 20 years her senior. There are a few that want someone of a certain age range, and this is specified in her profile. Much of this depends on you as well, as the age range is not set in stone, so to speak. What this means is that if you are very successful and are in good shape (not overweight), you may find a lady who is as many as 30 years your junior to accept you.
Q. How difficult is travel to the Philippines?
A. Basically the major airlines offer the same types of travel options to the Philippines as they do to any other foreign country. If you live within the continental United States, you can expect to pay between $650-$900 for a round-trip ticket during the "off-peak" season. Typically those who will pay less live on the West Coast since there is one less connecting flight. I recommend that you shop around for the best price and talk to independent travel agents instead of dealing with the huge on-line travel agencies which typically charge as much as 25% more for a ticket. Once you get there, either your lady will meet you at the airport if she is from the Manila area, or you will take a modern bus to one of the other major cities. I was surprised to find that the Philippines uses the same style of air-conditioned bus that is so common in North America.
Q. What about language differences?
A. The official written language in the Philippines is English. Almost everyone in the cities speaks English very well. As you get away from the cities, people tend to be more isolated and do not do as well with English. Some people in the cities speak English so well, that you forget that you are talking to someone who is foreign to you. And you will find that the writing skills of the average filipino is often much better than that of the average native English speaker.
Q. What is your guarantee on the addresses?
A. We do everything that we can to see to it that the addresses are current in our pages. It is inevitable that some girls will move or their e-mail addresses will expire if they do not log in for awhile due to a vacation or what-not. Therefore, if you scan a copy of a return letter or send us an e-mail failure daemon notice, we will give you your choice of TWO addresses for your inconvenience either from our current pages, or from a future update to the site. We are not able to issue refunds or credit due to the nature of the information provided however.
Q. Will you respond if I write you an e-mail?
A. Of course. Typically someone will check our main e-mail account at least 3 times per day and respond in a timely manner. We honestly don't get that many letters or inquiries, so you will be taken care of quickly. This is a medium sized site in a small industry. Sites like these do not get anywhere even close to the number of hits that the average dating site gets, either national or local. A safe bet would be to assume that your e-mail will be answered by us within 24 hours.
Q. How many men write to these girls?
A. Believe it or not, it is not anywhere near as many as you might think. As was mentioned above, most girls without e-mail get ZERO replies! The prettiest girls without e-mail will get one or two, but that's it. Most guys tend to only pick 1-2 girls to write, and they almost always have e-mail. Our policy is that when a girl has her address requested by about 8 different men, we will remove her from our pages unless she requests otherwise.
Q. How will I receive the addresses I purchase?
A. If you order through our secure system, it should immediately be delivered to the e-mail address that you provide. In addition, we display their contact information on a "thank-you" screen after you complete your order. It would be therefore in your best interests to "cut-and-paste" the addresses from that screen onto the 'notepad' feature of your PC.
Sometimes there will be a database error where the addresses do not get delivered. If this happens, simply e-mail us with the names of the girls you requested, and we will forward them to you as soon as possible.
Q. Why should I give this type of introduction service a try?
A. While this type of service tends to have the "Mail order Brides" stigma attached to it due to historical reasons, it is no longer the case. These ladies join this agency of their own free will and should be respected as such. If you think about it, this service is really no different than any other domestic singles, dating, and matchmaking service. "Mail Order Brides" is a term that means slavery and servitude. While true in the past and in illegal, underground sex trade operations today, it is no longer a normal part of the foreign introduction industry and mainstream websites such as this. The most significant difference that you will find with this type of service is in the quality of girls that you see. Most of these ladies would have dozens of men chasing them if they were single and living amongst us domestically. I have read statistics that show that for every single Asian girl in non-Asian countries, there are about 50 men competing for her affection. This is true from my own experiences, as I dated filipinas from areas like Chicago who would get "hit on" at least 5 times on any given day and were well aware how desirable they are to the average man.
But in Filipino dating sites such as this, there just is not this level of competition. Why? Because, for one, it is not a free singles service. Most men will avoid paying for a dating service. They convince themselves that they can find an unattached Asian woman on the internet. For a short time, I was one of those guys. But I quickly realized how pointless it was to go about the dating scene in that manner. You should use this little bit of information to your advantage over all of the others.
And the best thing of all, is that they do not have the same outlook on life or attitude as the average American girl! This is, by far, the most significant aspect. Most, if not all filipinas are Christian or strongly believe in God. Many of these same women specifically request a Christian man as one of their desired traits in a mate. While many women that you are used to would never cater to you like in old-fashioned times, a filipina will insist that she make you more comfortable. If that means getting you a glass of iced tea (without you asking) after a long day of work, so be it. She will do everything to shows that she appreciates having you as her man. There are not too many girls like this anymore (especially domestically), but rest assured that this character trait is ingrained in the mind of the average filipina.
Q. Are these Filipino women simply using me to become an American, Canadian, or European citizen?
A. While it has happened before, it is EXTREMELY rare. It is far more likely that a woman from your own area will marry you for your money rather than who you are as a person, statistically speaking. All these girls really want is to meet a man who loves and truly appreciates the love that they show to him. This "celebration of woman" is mainly a Western phenomenon. The average filipina comes from a male dominated area or household where it is common for the man to be lazy and get all the benefits, while the woman does all of the work with no appreciation.
In our modern times, most of these ladies life a fair life, devoid of poverty or truly harsh conditions. They simply want to try something new....in the exact same way that you are trying something new by writing to them. It really is as simple as that.
Q. What about getting her a visa?
A. This varies from country to country. In the United States, the law is very strict about immigration. Typically, it will take 3-6 months to get a "fiancee" visa, and a year to get a visa if you are already married. But if you have a minimum of a high school education, you can easily complete the required documents. For more information, please see our page at: http://www.manilabeauty.com/visa.phtml.
Q. How does e-mail forwarding work and how much does it cost?
A. Definition of e-mail forwarding: The interested man writes an e-mail sent to us in the form of an introduction letter to the girl he wants to contact. A member of the staff prints out the letter locally and sends it to the girl.
This is our e-mail forwarding plan:
For full members, we will be charging $2.50 per letter with a minimum of 10 letters sent at once. For 5-9 letters at once: $3 each. And then $4 each for 1-4 letters. Each letter includes a Philippine P15 international stamp for the lady to reply. But remember that since they live in or near the cities and internet cafes, many will likely reply by e-mail. Actually, the ones in Manila were complaining to my agent there why nobody has written yet
Note that you will see e-mail forwarding services at our competitors sites for a minimum of $5 each, and Philippine stamps for $1 each only if you buy 10 or more. Considering that express mail from the U.S. to the Philippines is $20 and it still takes a few days, our e-mail forwarding system is a great deal.
For non-members we offer the following:
$3 per letter with a minimum of 10 letters sent at once.
$3.50 per letter for 5-9 letters
$4.50 for 1-4 letters
Non-members may upgrade to a full membership by paying the difference for the desired membership option from their initial purchase to us through Paypal at http://www.paypal.com
Is preferred that payments are made through Paypal using the address: support@manilabeauty.com
Send your letter to that e-mail address as well following payment and it will be forwarded to the appropriate mailer in the Philippines.
Q. Where is your physical storefront?
A. Basically you are there now. We do not have a static address to keep our costs low and thus we can give better rates to you. The beauty of the internet is that all you need is a PC to maintain a website. We have men and women who live and work in the major cities such as Manila, Laoag, Cebu, Baguio, and their suburbs who find these filipino girls and offer them the option of joining the agency. At any given time, one of these "field agents" may also answer your e-mails, as they help to administer various aspects of the website operation as part of their duties.
Q. Do you have a brochure you can send?
A. Again, to keep our overhead down, we do not offer a brochure. We cannot justify a brochure, since the main purpose of a website is to give you all the information you need.
These are the questions that we most often get if someone does not read this page beforehand, and they are therefore covered here. If you still have questions after reading this, please e-mail us at support@manilabeauty.com and someone will get to your question as soon as possible.
Good Luck!

This will be especially relevant for Bandwidth co-ops.
The biggest obstacle to creating a co-op is having enough potential subscribers to convince the telcos that it will be worth their while to run the dry pairs the "last mile" from the DSL POPs to the houses. I am guessing that this technology will begin to allow metropolitan bandwidth co-ops to have an effective solution outside of the telco's control. Please, oh please, let broadband not suck forever.
These people are so stupid. This will never work.
Vivato's bases reach groups of users on existing laptops and other computers, with an operating range up to 7 kilometers outdoors, the company claims. Software controlling the antennas detects Wi-Fi clients in the area and adjusts the signal across the array many times per second.
Which is great, except when they overbook in order to maximize revenue, much like cell phone companies. Then we have spotty, intermittent coverage serving only a percentage of paying customers, as the system struggles to keep up.
Yay technology!

Well, Sprint Broadband works, it delivers >3Mbps, it's fairly easy to install, and it costs $50/mo. And I doubt it's a money losing venture, otherwise they'd have discontinued the service entirely rather than just not taking new signups.
If companies will compete with Sprint broadband using Vivato technology, that would be great. But with the Vivato APs being released in 2003, I think it's at least another year away until you are going to see viable commercial broadband services based on it springing up.
I'm afraid killing people takes precendence over informing them. The Pentagon reports that wi-fi networks interfere with their radar and further rollout of the technology must be curtailed. Read this article.

4 miles? That's all fine and dandy, but think of the implications aside from being able to connect in "pocketed" areas.
Too many "off-limits" zones in the suburbs of major cities for this to be any good. Considering the fact that upwards of %80 of the people that'd benefit from this live in such suburbs. PD's, FD's, Hospitals, etc. are all considered to be zones absolutely off limits to any such interference this would cause (suburbs are totally PACKED with these, There are 3 PD's and 2 FD's, as well as 2 Hospitals within a 4 mile radius of my house). That's FCC regulation that's been around since the '30s, and they're sure as hell not going to change them now.
Given the method they'd have to use to make sure they aren't broadcasting in that area, you end up with 1 or 2 degree swaths of no service areas eminating from the tower. May not sound big, but after a mile or so it gets to be the width of a city block.
I'm all for this, but a better solution would be to use smaller and cheaper arrays. Just find a way to lower the latency and it'd be even better.

An AMPS phone may be limited to 600 mW in the systems in Australia, but the actual limit on a Power Class 1 Phone is 5 watts. That is one of the reasons that replacing the AMPS system with (CDMA|TDMA) systems in the US has been very slow - a Class 1 phone can contact a base station many tens of miles away, which is IMPORTANT in much of the US - when you are in western Kansas, Nebraska, Wyoming, Montana, Utah ... you get the point.
That was part of why the old phones where so large - a 5 watt 100% duty cycle power amp isn't tiny. (the other reason was that since AMPS requires the phone to transmit and receive at the same time, the phone had to have an RF duplexer in it - not a small item, even at 800MHz. TDMA phones don't transmit and receive at the same time, hence they don't need the duplexer).
That's one of the reasons I tell people to look for the old phones at garage sales - get the phone and you have a dandy 911 phone - you WILL get a connection!
www.eFax.com are spammers
So how exactly do people with pie in the sky Wi-Fi plans intend to overcome 802.11b's inherent scalability problems? How many people can one AP REALLY serve?
From my experience I'd say that answer to that question is not very many. Having more than a couple people on a single AP is a recipe for pain and suffering. As the number of users on an AP increases so does the chances of packet collisions. As collisions increase the viability of the network decreases and you eventually reach a collapsing point where the network is unusable. A corollary to that rule then would be the larger your coverage area the higher a chance of collisions and thus a higher chance of the network collapsing.
You run into a similar problem with 802.3 which is solved by switching the network. With a wireless network you don't have the ability to add a switch in the middle of the network to keep the number of collisions down to a minimum. You're only got a bunch of nodes waiting their turn to talk. Switching channels isn't an option because APs can only serve particular channels.
With a coverage area of four miles then, the number of potential collisions on a channel is pretty high because your entire customer base could be in that four mile coverage area. Sweeping a broadbast between different nodes doesn't do much good on their end where all the static from other connections is an issue. On current networks you've got a small number of users because your coverage area is pretty small so problems aren't evident. You don't have problems on a wired network with only a 5 port hub either.
I'm a loner Dottie, a Rebel.
Makes sense that you can build a big-ass AP that will provide a large 802.11 blanket, but how is my laptop's little antenna going to talk back to it?

I've been awaiting the resurrection of Ricochet in Orange County, CA, but with a four-mile radius I could (using company money, of course--I doubt this new AP will be cheap) set one up at home and at the corporate office and have the effect I try to achieve using (past tense) Ricochet and (present tense) T-Mobile HotSpots. That effect is to change my environment to either a nearby park, pub or (what's a another p-word? It's early) other place while I work. Within a couple miles of both home and office I have parks, lakes, pubs, restaurants. . .just not the beach (maybe I still will need Ricochet!).

Please guys, this techonology is NOT about splattering megawatts all over town!
It is about aiming a low power beam in the right direction using a smart antenna AND that same smart antenna is a better listener.
It's a high-tech equivalent of a parabolic antenna and it is adjusted to radiate the same power at a distance as a normal omnidiretional antenna would do. That's what the FCC require in order to approve an antenna.
It's a common mistake to think that range=power. Note that this is a two way operation.

I understand that you are trying to be funny, but I see sooooooo much cell tower ignorance at zoning hearings.
First of all, people (including zoning officials) do not understand that radiation levels are not something that can keep out cell towers. That is an area which has been pre-empted by federal law.
Second, they do not understand that cell phone radiation is not ionizing radiation. It cannot break chemical bonds and cause genetic mutations. It could cook you if you stood close enough and it broadcast at a high enough power, but it cannot cause cancerous changes. These people hear "radiation" and think "Godzilla" not "reading lamp". It's just blatant science ignorance.

Lots of petrified grits
Actually, the FCC doesn't limit raw power, it limits power per solid angle steradian (actually, it's usually max power/square area at a certain distance -- effectively the same, but no confusion over near-field effects of the antenna). Just like using a magnifying glass to concentrate sunlight, it can be just as dangerous to concentrate RF power - and the FCC knows this.
Still, the increased bandwidth due to multiple beams will be very helpful in overcrowded environments.

SAN FRANCISCO, Dec. 16 -- The Defense Department, arguing that an increasingly popular form of wireless Internet access could interfere with military radar, is seeking new limits on the technology, which is seen as a rare bright spot for the communications industry.
Industry executives, including representatives from Microsoft and Intel, met last week with Defense Department officials to try to stave off that effort, which includes a government proposal now before the global overseer of radio frequencies.

Dear Tiger Direct,
Do you offer volume discounts for 802.11 equipment? We are interested in many hundreds of thousands of these and will gladly pay in counterfit US dolars, oil or gold.
Sincerely, your friend.

Dear Editors:
I was most interested in your article in the Fixed Wireless Business section entitled "Hams Are Your Friends" and appreciate the premise of the article. However, the members of the ISP-Wireless list held some rather substantial misconceptions about the status of Amateur Radio allocations and the use of them by unlicensed RF devices such as wireless LANs and other Part 15 Devices. I have served as the General Counsel for ARRL, the National Association for Amateur Radio for more than 20 years, and practice communications law exclusively.
A concern in your article is that high-powered Amateur transmitters might preclude the operation of Part 15 wireless internet access devices, especially in the 2.4 GHz band. A recurring theme was that, while this could happen in some instances, Amateurs are precluded from causing "intentional interference" and that they could be precluded from operating if interference to these Part 15 devices occurs. Not so.
Part 15 unlicensed devices operate without any spectrum allocation at all. They can continue to operate in bands used by licensed radio services (1) only as long as they do not cause harmful interference to licensed services, and (2) provided that they accept any and all interference received from licensed radio services. FCC rules are very clear on this subject. It wouldn't matter whether or not a licensee in, for example, the Amateur Radio Service knows that a wireless LAN is receiving interference at 2.4 GHz; the Part 15 user operates devices in that band on an "at sufferance" basis.
Why the distinction? Only this: the Communications Act of 1934 requires that all radio communications be done pursuant to a license from the FCC. Part 15 devices are allowed to operate without licenses because their potential to cause interference is extremely low (in theory; in practice, the FCC has pushed the concept to, if not beyond, the breaking point) and because they are not protected from interference. The big benefit is for the manufacturer and the user, who can sell and use products that don't have to be licensed. Avoiding licensing is a big benefit to users, but it comes with the price tag of the complete absence of protection from interference and the absolute obligation not to cause any.
The thrust of your article, that cooperation between Amateur Radio operators and users of Part 15 devices is key to coexistence, is correct. Amateur Radio operators are generally willing to cooperate in addressing interference situations and happy to help if asked. But the Part 15 device user is not entitled to any interference protection, and must protect all licensed services against interference. It is good for all parties to know how the playing field looks before the game starts.
So if they're directing a beam at me, does that mean my physical position is traceable too?
The only answer is to use an easy to customize, stable and relativly secure operating system and lock it down. This will lower the chances of your machine being owned by someone else who will then use it to search for content of interest, store mp3s, movies and kiddie porn, or to harrass others, yet not throw out the whole purpose and promisse of the internet: the sharing of information and computing resources.
I'm very very tired of people transfering their eXPerience with worm, virus, hole plauged operating systems to "security" of the internet. Not every machine in the world is brain dead enough to run an email client as root and automatically execute attatchments. Some people use freely available secure communications packages like OpenSSH. Get a clue people, especially you, Uncle Sam.

My understanding is that the 802.11b RF bandwidth is currently limited by the 802.11b protocol.

However... a new variation of 802.11 -- 802.11g (yes "g", not "a") will increase the data rate to 54mbps. 802.11g is also supposed to be dual mode and support 802.11b clients.
(The link above is http://www.extremetech.com/article2/0,3973,21749,
It turns out that if one of the antennas in the link is high-gain, then it is high-gain on transmit *and* receive.
Consider cell phones.. the phone has this tiny little antenna, but the cell site has a big honking high gain antenna that concentrates the RF in a pancake, and in some case in just more-or-less one direction -- e.g. towards the highway.
Hence, this thing works with standard laptop cards. Pretty neat, eh? jeff
It's shocking that the new administration is following the greedy, ignorant policy of it's predecesor. If such services flop, those who opposed the specturm auctions can say, "I told you so," and that will be that. It's not like the telecomunications has been a stable source of employment for most of the people working there. If the government forgives the auction debts, it will ammount to a huge bail out of big corporate interests. That's bad because it give an advantage to those who bid irresponsibly and continues the ineficient specturm use but at least it will provide service to people at something closer to its cost. If the government legislates 802.11 out of practicality, it will be a huge scandal as the only reason will be to prevent new entrants from ruining these silly third generation services. Yet this third option is the one that keeps comming up. Keeping the public from building their own communications networks, which are technically possible, ammounts to a denial of first amendment free speech rights.
Bandwith scarcity is a lie and services that operate on that principle, metering out kilobytes of data, are a rape.

Yes. (which may be a good thing -- sites that implement this technology could conceivably track down the location of rogue APs or clients.)

If they are trying to be a big time provider, range doesn't matter so much if they can't serve all the people that want to be served in that area.
Name calling is nice, thanks asshole.
I'll bet you never even read the paper I cited.
You might try a valid link to something that's not a huge pdf file. Your link did not work, and I don't like multi megabyte pfs where text can explain the concept.
I don't know why I even bother responding to your drivel, but still...
I know why, let's look and see.
802.11 was designed to provide confidentialty, access control and data integrity. And the paper cited demonstrates that neither of the three are achieved (in very practical attacks... not something involving million-dollar machines)
Aha, you respond because you are a troll. That's not the stated goal of 802.11, now is it? Would you mind responding to the fact that all communications are insecure? It's all very nice of you to call me an idiot, but it would be better if you informed me. As I see things now, you don't need million dollar equipment to tap a phone line, a cable, listen to microwave tower transmisions or most other forms of current communications. None of these forms of snooping takes much more effort than setting up a 802.11 bug. Others with larger budgets can spy on stand alone machines, but even there, I doubt that off the shelf light analysis equipment costs millions. You could hire a competent engineer to build one for you for $50,000 in a year plus a few equipment costs. Encrypted communicatins over 802.11 works as well as encrypted communications anywhere else.

I would like to see a better explanation for how clients can talk to the AP over many kilometers. Just by the AP having a "big ass antenna" won't cut it, since by then, the received signal is weak, and amplifying it (say, 14 dB or more via an antenna) will amplify noise as well.
Rough estimates:
30 mW transmission like in Orinoco cards(100 mW being peak) = just under 15 dBm.
Losses in free space, assuming Line of Sight, are 106.5 dB for 2 km.
So, signal is down below -90 dBm. At this point, signal to noise ratio will kill you, regardless of ANY gain from the receiver at the AP.
Peace
Sprint uses an MMDS network, running in LICENSED spectrum. This phased array runs 802.11b in 2.4Ghz unlicensed. I operate a 802.11b based fixed wireless ISP, and while fine for a small markets, it is NOT the answer in crowded urban centers. Or even large suburbs for that matter. Any Joe Sixpack with a Linksys WAP11, an omni, and a big amp could potentially take the network down. Since MMDS is LICENSED spectrum, you can face fines from the FCC for operating in those bands without the license. The equipment cannot be purchased at Circuit City, so it is less likely to be snooped like 802.11b, or interfered with or stolen. The amount of bandwidth available in the MMDS bands is also WAY more than 802.11b provides. I could go on and on about how 802.11b is NOT THE SOLUTION FOR WISPs, and how MMDS IS, but I will leave that for another day. Bottom line, MMDS fixed wireless is NOT outdated, 802.11b is.
If you can't figure out my address, just drop me an e-mail and I will explain.
That has nothing to do with phased antennas arrays. A phased array has more than one antenna. When you use multiple antennas your bandwith goes up whatever protocol you use. The trick is that phased array antennas are all in (nearly) the same spot and cooperate in a sophisticated manner.

Antennae on trees tend to sway quite a bit and if you're dealing with directional ones, its not going to work.

Exactly--and that's part of the security advantage--you try to hack a system that you're not supposed to be in, and the system tells the administrator which car you're parked in outside, so he/she can call the police and tell them who you are...
Not any harder to get into, but a lot more risky.
According to the stuff they've released, Vivato has/is working on software to specifically do this.
