StDave writes "Yesterday Cisco announced a very cool technology. It is a 44Mb wireless technology that doesn't require line of sight and has a range of 30 miles. Take your ADSL line on the road with you. " Wow - they've found a way to use the "ghosting" caused by obstructions to tv and cell signals. Base units will cost around 150,000$ and the transceivers will be under 500$, with start of marketing sometime around June.

Americans may think wireless technology is cool, but they miss out on so much by not using GSM mobile phone infrastructure. Roaming. When a European goes to America, their mobile phone still works. Amazing, huh? Not really. Get with it, folks.

I'd wait and see what sort of encryption they're going to use for this before jumping on the bandwagon. I wouldn't particularly like to have my data broadcast all over the city if all they offer is XOR "encryption"...

Break the Monopoly! (3)

Ex Machina (10710) | more than 14 years ago | (#1487747)

This kind of system gives a small to medium size isp a chance to break the monopoly on broadband (DSL/Cable) Internet connections. In my area (SE RI/MA), (Cox) cable internet is unavailable, MediaOne RoadRunner is nonexistant, DSL is a year off, T1 is overpriced and ISDN is crappy. If an existing dialup isp implimented this technology, it would be a great way to move into the high bandwidth market. Someone doing this could force broadband companies to compete, which is good.
What about security though? I assume they'll have link level encryption.

This will change the ISP landscape (2)

color of static (16129) | more than 14 years ago | (#1487749)

I've been looking for something like this since my days as an undergrad. Wireless has the unique ability to take all your expenditures and put them up front. I can see a local ISP buying two or three of these and having the same coverage as they do now. After that they just have to collect enough money to pay for overhead and the P&I on the loans.

There are problems though. In my area a 30 mile radius encompasses a few million people. Is there the ability for orthogonal coding or seperate channels, or is this bandwidth shared per foot print? How many orthogonal channels are capabale in a footprint? If it's not a lot this could be worse then cable modems (I used to work with cable modems in high density installations about 10 years ago, and after the first large group gets on you wish they hadn't).

MMDS isn't all that new,,, (2)

MrGrieves (53464) | more than 14 years ago | (#1487750)

If I recall my Future Tech class correctly, a few cable-alternative services have been using MMDS for nearly 20 years. I'm pretty sure that Cleveland and New Orleans services still exist today. It was cheaper to set up MMDS towers than to string cable through an already-dense wire-line infrastructure, apparently. Are there other markets outside of the U.S. that currently make use of MMDS?

Still, it's very cool to have yet another fat pipe, especially since it's wireless. I'm just sort of puzzled that the article seems to be implying that MMDS is some sort of fantastic new invention. The Cisco tech's a novel use of the spectrum, granted, but the bandwidh's been there for a while; since the beginning of time if you want to be literal ;-) Before I get myself into a cosmological debate, I'll just stop here.

The $64,000 Question (4)

Amphigory (2375) | more than 14 years ago | (#1487751)

If per station... err... Please mommy?

Impressive Engineering Feat (5)

alexhmit01 (104757) | more than 14 years ago | (#1487752)

While not terribly difficult in theory, that it works over such distances is an impressive feat of engineering. However, I would like to see how it works in the real world. If it compensates for interference by lots of resending, dropping bandwidth, that's fine, but if it cuts out, that's a problem.

While I don't doubt the article, I want to see it in production before I praise them too much.

One thing that I've always wondered, why do we see so few high bandwidth wireless technology. I mean, one should be able to just use more frequencies. I guess that there is a real shortage of available frequencies. I wonder how much of that is technical hurdles and how much is beaurocratic messes between the DOD, FCC, etc., fighting over it.

Well, as IP carries more and more information, I wonder if we'll be able to reclaim all the bandwidth from audio/video broadcasts as the world moves digital. HDTV promises more (over the airwaves) channels because the signal is smaller... that seems a little silly. People that want more channels currently have Cable and DSS options, and Telephone will do so too. I think that society has more uses for the airwaves than broadcasting more garbage. As long as people get reasonable channels for their kids, news, and evening entertainment, I think that society would be better served by allowing new technologies to claim the bandwidth... but that's just me.

On the other hand, more radio stations with lower barriers to entry (licenses trump the real expenses) so that there are real alternative stations instead of the same drivel on all of them.

Security and "Dropped" Data (2)

Deitheres (98368) | more than 14 years ago | (#1487754)

Two questions:

1) What kind of security will be implemented? What kind of ecyrption will they use to make sure no one will catch all my "bits and packets" (hehehe kind of like "bits and pieces") and seeing all my pr0n?!?

2) I have a cellular phone from a certain digital provider that will remain nameless (::cough:: sprint pcs ::cough::) and I have dropped calls ALL the time. Does anyone think this will be a problem? I don't wanna download the latest Pam Anderson video and find out the middle half of the .avi got dropped ;-)

Cool, but not going to revamp telecom (2)

netpuppy (77874) | more than 14 years ago | (#1487757)

Nice tech and all (I work w/Cisco prod all day long, and am a cheerleader most of the time) but there is no way that this will free us from telecoms. Distance limitations are unacceptable, unless someone wanted to build a system that bounced data from one side of the country to another using this ... and that would be very prohibitively expensive.

I like the tech, on the other hand, if it can be developed as a service-provider based alternative to microwave. I have seen DS3 microwave systems going moderate distances across a metro area, and you end up saving the cost of the hardware very quickly when compared to paying local loop fees for that kind of circuit. If this could be rolled out by a motorola as a point-to-point connection between business buildings, with cpe hardware costing a few hundred dollars, they could bank.

Maybe that mythical Metro Area Network will emerge eventually, after all...

You or the ISP could use any security you want. It sounds like CISCO has solved the hardware and other technical problems of wireless networking. Software would probably be up to the ISP. As for PCS, I have AT&T and have NEVER had a dropped call even when I left the central caslling area for the back woods.

Maybe this will tell BT where to get off? (2)

anthonyclark (17109) | more than 14 years ago | (#1487762)

Hmm,
Here in the UK, BT have announced that a 512Kbs ADSL line will cost the end user 50 pounds a month plus installation and equipment costs. If this new Cisco wireless stuff really can give me 44Mbs all to myself with no connect charges... I'll buy one straight away.
Hopefully Cisco won't delay selling this stuff in the UK. (which is what normally happens) I could see quite a few people in the UK switching to this kind of technology if it can deliver what it promises. (Like we all believe press releases...)

Where do I sign up?

On another note, if I could get 44Mbs over 30 miles, would I get 4.4Mbs over 300 miles? I realise that is an oversimplification, but 4Mbs+ over 100s of miles would be a godsend to countries with poor infrastructure (e.g. Africa, Russia)

Great but expense? (0)

Anonymous Coward | more than 14 years ago | (#1487763)

Well, this is great, but what about during rain and thunderstorms? I can't afford the $40-100 dollars per month for the slow stuff at 500K/100K up/down speeds. Can you imagine what they'll charge for this speed? Hope it's more like $9.95 unlimited per month with roaming in any state or country! Moreover, the base station is really going to be bandwidth constrained with everybody hitting them at 44mbs. Why don't telcos just bite the bullet and run 1Gbs fiber to all of our houses. Thus, the internet speed wars would then be over! :)

jd (1658) | more than 14 years ago | (#1487768)

The Government is considering allocating frequencies for car navigation systems. CISCO comes out with a device which would essentially permit cars to transmit/receive large volumes of information in real-time.

Coincidence?

Maybe so, but even if it is, you've now got virtually all the ingredients needed for "car traffic control" systems. All you'd need, to finish it off, would be some decent sensors on the cars, to detect what objects are near, and some means for a central computer to determine optimal paths.

The latter part is almost done, with existing car navigation systems, but this would need to be a bit more refined.

I see a lot of potential for this device, far beyond mere wireless web surfing.

Re:Maybe this will tell BT where to get off? (0)

Anonymous Coward | more than 14 years ago | (#1487771)

If the power of the signal was proportional to the square of the distance from the transmitter, then the following could be true:

3 miles: 100 times the signal strength ~= 4.4GBps
30 miles: 44Mb/s
300 miles: 0.44Mb/s
0.3 miles: 440Gb/s (here you can see why this is an obvious over simplification....)

Of course, there is a lot more to consider than the oversimplification above... the reflections, data transmittal frequency and many many other things would mean that you would probably get 4Gb/s over 0.3 miles, and 0.4Mb/s over 100 miles...

Oh, what do I know...

Re:Break the Monopoly! (2)

dattaway (3088) | more than 14 years ago | (#1487772)

I agree too, remembering the pain ISDN problems (read lack of service for weeks while getting the runaround from BellSouth) and have dreamed of bypassing the phone company with microwaves. The $150,000 seems a bit steep, but I guess that's the price for a massive base station.

It would be nice to see something I can afford for my own little network. I hope the $500 units have an option network together in the spirit of the internet. I'm using the 2mbps Zoomair modems around my neighborhood in a simple network. Too bad they don't cover the city . . .

Solution to the "Last Mile" problem? (2)

adimarco (30853) | more than 14 years ago | (#1487774)


While I'd like some more technical information on this, my first thought was that this may be the (relatively) inexpensive solution we're looking for to solve the infamous "last mile" problem.

I'm not sure how much it costs to lay fiber, but I'm willing to bet it's not cheap. I'm betting it's even more expensive in more dense, urban areas. While your average Joe can't afford to cough up $150K for the base unit, your average telco *can*.

Imagine getting your home net access wirelessly. Your ISP could sell or lease you the receiver unit in much the same way that some people lease their cable modems. The connection speeds are higher anyway (is this 44 megabits shared? anyone know?).

The increasing use of wireless networking technology has us all focused on dinky little PDA things, dreaming of roaming connectivity. It had never even dawned on me that wireless connections might be the solution to the last mile problem.

I'd be a little worried if I was a cable provider...

According to the article:

For 3000 simultaneous users at ~28k, you'd need about 80meg. For 3000 at 1000x ~28k, you'd need an 80,000meg pipe (~80Gb). Someone please check my numbers, because either the article is fscked or I can't do simple arithmetic.

In an attempt to resolve a problem that has plagued television watchers and cellular phone users in big cities for years, Cisco plans to market technology that essentially harnessesand redirects the voice and data microwave signals that bounce off many obstructions in large cities.

What about rural areas in the Midwest U.S.? Can they take advantage of this? Or rural areas in the Appalachias? Can mountains obstruct signals like buildings? If not, rural mom 'n pop ISPs will not be able to justify the expense, placing rural areas at yet another disadvantage. Still, sounds really cool.

Why do you feel will it blow ISP's out of the water? Someone has to provide the pipe to the backbone and that's what the ISP's are there for. What this will eliminate is the phone company. And lower the costs of phone lines to an ISP. Imagine owning an ISP and not having to pay for 10,000 customer phone lines each month and just paying the one time cost for one $150,000 base station. Looks like a good deal to me.

What I am thinking about is how apartments in urban areas, such as New York, Chicago, LA, could speed things up with these. With 3000 users on a such a setup, it would require more than 300 of such units for a population of one million... Even more in the major urbanc areas.

no, probably not, i'm afraid. the article didn't say anything about what kind of frequencies were involved, but if they are using vhf/uhf/microwave/etc., which they almost assuredly are, then line of sight is about the limit (i'm only talking about the distance the radio waves will travel, not how the technology will compensate for buildings and such.)

really, it would depend upon how high up they got the antenna. if you had a mountain nearby, it could conceivably cover much, much more than 30 miles...doubtful this would be the common situation, i'm afraid.

Re:MMDS isn't all that new,,, (3)

Gurlia (110988) | more than 14 years ago | (#1487783)

Sure, usually when "real" leading-edge (or bleeding edge) technology gets to common people like us, it has been "there" for long years. (Though, in the software world the timescale is many months rather than many years). It always takes somebody to take the step to implement something based on that technology so that it is accessible to the public.

Just like most new OS technology/concepts usually goes around only in academic circles for a while, before somebody in the industry decides to actually use it to produce "real" OS's for people to use. (Eg. witness how many years behind Windows is in terms of OS design? Even Linux is still based on macrokernel design, and very few people even know about Hurd which is based on microkernels -- arguably the "front-line" of OS research. But by now, there's probably already something newer.).

It's always easy to criticize in retrospect (yeah Cisco didn't do anything like, new, this MMDS stuff's been around for 20 years, yeah but nobody except researchers could use it until now.) Just like Columbus said that he can stand an egg upright. When greeted by disbelief, he proceed to simply crack the bottom of the egg slightly on the table so that it would not roll over. The people then criticized, "That's cheesy, I knew how to do that all along!" It takes a pioneer to take what looks like an "obvious step" in retrospect.

Back to my point: I think it's a good thing Cisco took this step to make this technology available to people. I wouldn't be so quick to point out, like the people who criticized Columbus, "but hey, this technology's been around for so long!" Having said that, let me just add the standard disclaimer: I do not intend this as flamebait, nor am I trying to criticize Chris or anybody else. Just pointing out something... (you never know how people can misread you on Slashdot, better disclaim everything!) :-) And of course, if this technology is going to be available any time soon, I want to try it!!

Re:The $64,000 Question (1)

Deosyne (92713) | more than 14 years ago | (#1487785)

I would imagine that being a wireless connection, that would be 44Mbps per user; the real bottleneck will occur with a packed station carrying nearly 3,000 independant connections that have to go through the land line connected to the base station. Of course, they could nail an OC-3 to it, but what is that going to translate to in terms of cost for the end user? At least the cost of the base station is negligable; $150,000 to support 3,000 users comes down to only $50 a user, although the receiver that the user has to have is $500. Those prices will come down, too, so it will be an even bigger bargain, particularly when talking about billing a customer monthly. :) All of this is theoretical, of course, but this new tech may be the real high speed access method that replaces dial-up, as long as its more reliable than the problematic cable and DSL solutions.

Sorry about the double post, my first time and I may have screwed it up :) Is this use of the "ghosting" really new? It is common practice in digitial wireless technology to use a RAKE receiver structure to resolve the reflections and recombine them to use the reflected power in addition to the line of sight path. Id be more curious to see what spectrum they are using and how their broadcast bandwidth efficency and absolute bandwidth compare to current technologies. I would think that that would make the definable difference. BTW 30 miles in an urban terain is going to require a _LOT_ of power, espically if the 44Mbps is not shared.

Doesn't it seem like the days of the high powered transmitter broadcasting 80,000 watts of music power are over? I predict there will no longer be high powered TV and radio transmitters but instead we'll have small transcevers on every block covering just that block, channeling TV and radio on demand over the same protocols as internet traffic. They're already going to deallocate the FM, AM, and TV bands. Why not just make that the end of high powered transmissions and make us all use cell recievers.

I think you're off - but they can't be right either.

Where you make a mistake: A 56K bits modem transfers (about) 6K bytes/second compressed and 12K bytes/second uncompressed. That's what I see, so feel free to give me alternate numbers if I'm in error.

If we take 1/2 of the uncompressed rate to simulate a 28K modem and multiply it by 1000 then by 3000, and divide by 1024 to get K bytes, we get;

6144x1000x3000/1024=18,000,000 (K bytes)
18,000,000/1024=17,578.125 (M bytes)

17,578 MB/second is still impressive ... except that the other numbers they provided don't match this.

Using the $150,000 transmitter cost divided across the 3,000, this would break down to a one-time cost of $50 at the transmitter. Hell, any medium-sized community could easily afford one of those things. Yet, the 80meg transfer rate doesn't match the 44Mb (not MB) transfer rate. There's some loss or delay that must be accounted for -- and I don't see it.

The only way this makes any sense is that they are taking into account delays and pauses typical in sending the packets, or maybe they bunch up the packets per-user -- actually transmit to a fraction of the users -- and then call this "simultaneous".

I'm surprised at the amount of response to what is basically puffery from Cisco marketing. Those of us in DC or San Francisco have been able to use Ricochet wireles for a few years now. True, the speed is 28.8 kbps, but Metricom is rolling out R2 in early 2000 to 28 markets. R2 will be ~128kbps, fully wireless, and work at up to 70 miles per hour, i.e. driving down the highway. It's been testing okay, and should be priced between $50-100 per month. IMHO, this is a lot more interesting right now. Yours truly, Mr. X

Greeting from Newbridge Networks, where wireless LMDS networks (higher microwave frequencies used = MORE bandwidth) are already available TODAY! Read about it now! [newbridge.com] Come get your OC-3 or T1 pipe... ethernet available too...

Just so you know, I write this from the background of a hardware engineer in the Wireless group at Newbridge. If you have any questions, please post them. I'll be watching. Otherwise, try emailing me at "myname"@newbridge.com

I have SOOO many comments to make, I'm going to have to make them in point form otherwise I'll be here all day. So, here we go:

1. What Cisco is proposing using multipath effects to avoid the line-of-sight problems is asking a LOT. I really doubt this is possible. I was involved in a research project over a year ago that basically ruled out this from being possible.

problem A: If you use a non directional antenna (easiest to set up, no alignment issues) you are then presented with the amount of processing needed to weed out signal from reflections - it is enormous. Your antenna also has no gain - a big problem with lossy low power MMDS or LMDS systems. No signal = lots of noise = low bandwidth or high error rate.

problem B: The other problem is cost to install a system like this. Lets say you find a nice shiny building to bounce your microwave signal off of. It's a LOT tougher to align your dish antenna to a unknown point on a building (trial and error) then to point your dish to a fixed known point. This could NOT be done by joe blow on his roof - you would need a pro installer to do this with specialized test equipment = $$$$$! You also need to do LOTS of thinking about what reflection you are going to use - too much work to make it cheap. TIME = $$$$.
The numbers they are quoting sound like marketing magic.

Enough marketing hoopla. Check out what we built... and you can have today!

Here's a few more links for you. Good techie stuff.

Check out: How to maximize the use of your available spectrum [newbridge.com]

and

Newbridge features, like QOS and awesome network management. Does CISCO offer this end to end networking? I think not. [newbridge.com]

More points:

This technology doesn't work on the move. It isn't meant for vehicle platforms. Fixed sites only.

30 MILE range? I think not. NO WAY they could get regulated. Think of the interference problems on adjacent cells, especially since they are using the multipath effects.

Typical cell sizes for LMDS MMDS systems are around 4 Km. (2.5 miles)

ISP's love this stuff because it can get them into peoples homes - last mile. Don't need cable, dont need phone lines.

If you have any questions, please post em. Man, the signal to noise ratio in this topic has been pretty bad. I hope this helps clear a few things up.

I didn't see in the article which range of bandwidth this uses, but I'm guessing from the price that it's not public 10.4Ghz. My company is a Lucent WaveLan reseller, which runs in this public range -- as do microwave ovens and other troublesome devices.

>>> One thing that I've always wondered, why do >>> we see so few high bandwidth wireless >>> technology. I mean, one should be able to >>> just use more frequencies. I guess that >>> there is a real shortage of available >>> frequencies. BINGO! Go sniff around the FCC web site and look at Part 2 of the FCC Rules and Regs for the table of frequency allocations. You'll quickly discover that there is a finite amount of spectrum available, and if you want more spectrum for wireless networking, you have to get it from another service to which it's currently allocated. The FCC has been working very hard to make more spectrum available, and in most cases that involves sharing and various techniques such as spread-spectrum to minimize interference. The spectre of a long-range wireless networking service bothers me - this implies that there will be one loud-mouthed base station somewhere trying to listen to a bunch of weak client stations, which means that the tolerance for interference with other spectrum users will be minimal. Sounds selfish to me...

GSM clarification (3)

fuzzybunny (112938) | more than 14 years ago | (#1487806)

GSM/SMS is, more than anything else, a toy. Currently, it's not implemented at anything over 14,000bps, and the error checking done at the base stations knocks it down to 9600. It's fine for alphanumeric paging (via SMS) and caller ID, but then again, TAP messaging (used by your boring old pager) works just as well, and call origin is also no big deal.

Also, European mobile phones generally use the 900mhz band. All US cell phone providers I am aware of use 1900mhz, so unless you have a dual-band phone using that wavelength, you're SOL (many European dual-band phones use 900/1800.) In any case, most dual-band European phones I've tried in the US have poor range compared to local PCS phones.

What I really want to see is the toys Qualcomm [cnet.com] was talking about a while back. That'd really make wireless data traffic fun. And if this Cisco bit can do even local roaming, like ricochet, you're still doing very well.

Not to be too picky, but that wasn't Columbus. It was actually the Renaissance architect Fillipo Brunelleschi (maybe I spelled that right??) in Florence, Italy. To the actual point, Cisco isn't promising 44Mbps. In their specifications for the wireless modem card for the uBR7200 series router, they are very careful to point out that the data rate may be up to 44Mbps if you have a 12Mhz channel. If you only get a 6Mhz channel, the best you could hope for is 22Mbps. Still, even if there is a loss of 50% on the data rate, even at the lower input bandwidth, the speed is still substantially better than the G.Lite speeds being offered by DSL carriers in my part of the world (if you're fortunate enough to have your line qualify). Also, those are full duplex data rates, so you don' thave the upstream/downstream issues you get with ADSL. I'd definitely be willing to try it. I only wish I had the funds to get to become one of those lucky ISPs to get it first :)

The fact that it's wireless is irrelevant. It doesn't matter what medium the signal travels through, whether it's air or copper, bandwidth is bandwidth. It's dependant on the transmission frequency. If the transmitting tower is only capable of a total aggregate bandwitdh of 44Mbps, then it has to be shared by all users of that tower.

Probably what will happen is that you will have to purchase levels of service like with ADSL, rather than a single speed level that's shared by all users (like cable modems).

In fact, I get my TV signal at home over a MMDS link today. It's been available for about 3 months here in Ottawa, and it is sweet. They are planning to roll out high-speed internet access early in 2000.

But I think the Cisco technology differs in that it allows you to not require a line-of-sight to the transmitter. I have a 15ft pole on the top of my house with a directional antena on it so I can receive the signal. Lots of places (downtown, wrong side of an apartment building, etc.) can't get the service since they are not line-of-sight right now. This tech from Cisco would fix that.

This is either absolutely incredible or incorrect, as it would be the first commercial wireless product to do multiple symbols per wavelength.

Perhaps it's 12 and 6 GHz instead of MHz?

If it is GHz, it's still incredible that they can go 30 miles with it and/or (which is it? :) do non-line-of-sight connections.

Radio waves bounce off of buildings really well, the signal is still quite intact, the only problem is you get multiple signals due to multiple bounce paths to you, each one slightly delayed by a different amount (speed of light isn't so fast anymore once you deal with picosecond waves).

Looking at the technical specs it appears they not only worked around this problem but somehow used it to their advantage [cisco.com] .

High Speed Wireless, don't believe it... (1)

Anonymous Coward | more than 14 years ago | (#1487837)

There are a few issues with high speed wireless data that Cisco has failed to mention in their press release.. The first and most important issue is the fact that they don't mention spectrum and/or frequency range per channel... These are so important due to the fact that if you have a system that uses frequencies that are expensive/impossible to license you have a dead product... The spectrum of that frequency that is used per base station, user etc.. Is important because if you purchase a 100mhz block and have to use 20mhz for each "node" on the cell site, and the fcc only allows that portion of the spectrum to be overlapped in an oh so finite way.. It could become impossible to make money of this thing becuase you can't deploy it. This product has to use a high frequency, (+2ghz) and use a large portion of the spectrum to achieve it's data rates.. (20mhz or more) At least to achieve those data rates consistently at long distances. The problem with a small spectrum lotsa signalling (datarate) and long distances is that it will become harder to filter out what is data and what is noise. You can only fit so many oscillations in the wavepath before even minute changes make it impossible to reliably communicate a signal. Your only options then are to make the wavelength longer in the same space of time (more spectrum) or to get really fast, and accurate chips to decode those wavelengths reliably. Then the question is raised.. Just use a really long wavelength!.. Problem with that is that you have then a signal degeneration issue due to the fact that different frequencies travel ever so slightly differently through the air. And when they get to the destination, can be just as impossible to determine if that wavelength was signalled in the same slot or the next slot.. Slow down the slots and now you have a inherently lagged to hell system... Bottom line on this cisco thing is that you get 44mbps directly below the tower, but the reliable data rate actually ends up being 20mbps 5 miles out... 10mbps 10miles out, and 5 at 15miles, etc.. etc.. If that.... (don't count on it due to the fact that theoretically you could do this on paper, but factor in environmentals and you go to hell)... Oh yes, did I mention that these are probably FULL duplex rates? Realization on a download or upload will only be half of the above advertised value in the press release.. (unless of course you are doing both u/ling and d/ling at the same time OF COURSE assuming that your modems are not asymmetrical... Bottom line, it's cisco's hype to try and capture a market before it actually gets a product... Benchmarketing has been around for a long time... Wait until real world trials and test data come back from this whizbang technology...

Absolutely, it's a start ... as microwave systems were also a start. Problem here is that your basic distribution systems are all fiber-based. Satellite (in current form) is too latent, RF or Microwave doesn't go far enough clean enough, etc. etc.

So even if it is built in such a way that you are freed from the local loop charges of your DSL line, the cost is still going to be handed to you by your provider as they have to pay localtelco for local loop charges on the circuits they add to take care of increased capacity, and long-haul carriers for more backbone capacity, and so on.

An even better start, in my mind, would be to design a system like this that does voice/vid/data, and frees you as a consumer from Ma Bell's + Cableco's presence in your house. Of course, that requires 99.999% reliability, and all that, so it is a long way off.

The use of ghosting is to get around things that block line-of-sight. In rural areas you don't have a forest of buildings. If it's flat, you have line of sight. If it's hilly, treat the hills as "buildings" and pick up a ghost.

If it's a forest of trees you might have a problem.
