Wi-Fi, Linux, And VoIP In Canada
WEFUNK writes "Canadian Business magazine has a cover story promoting Wi-Fi, VoIP, and Linux as 'Stuff that Works: 3 hot technologies that live up to their hype.' The article goes on to describe a number of Canadian success stories, ranging from Spotnik Mobile's growing network of Wi-Fi hotspots to the Canadian National Railway's use of Linux since 1993, and quantifies the benefits of VoIP to a Canadian insurance company's call centre. The article also includes some shipment numbers for Linux servers in Canada, mentions the growing number of Linux apps, and nicely downplays the SCO debacle."

The protocol is rather inefficient, because of the Canadian necessity of adding "eh?" to the header of every packet.

Thank you folks, I'll be here all week!
What are you talking aboot?
Nice to see some good news about linux in Canada, I am a student in a canadian University (Université de Sherbrooke) and Linux is installed as a desktop on many of our labs.

I know that intel's facilities use VoIP for thier internal phone calls. I heard they had problems with the clarity, and had to add noise creation mechanisms to the chips because people thought the other party had hung up due to beautiful silence. :)
So this is one of those "look into the crystal ball" articles. A quick look at the numbers show that Linux adoption is levelling off, as are all server OSs across the board (with Solaris and BSD (is dying!)) actually decreasing in market share).
So you've got two technologies that are succeeding here, WiFi and VoIP. And you've got one that's doing okay, Linux.
It's certainly not 1998 and Linux is the new hot thing. It is 2003 and it is the old OS with a good rep. It hasn't lived up to all of its hype (it still sucks as a desktop OS despite your mama's running of it at home), but it has nicely fit a niche in server software that was completely dominated by some big names like IBM and Sun previously. That's not too bad.
I have been pwned because my
I would have been kind of annoyed if this was modded as funny. (Well it was.) But it irks me even more that it was modded as redundant ;-)
VOIP is illegal to run on Linux because its made by Microsoft. And I thought that VOIP is slower than DSL so why not just use to mics's to connect the telephones or just use cell phones, eh?
... therefore I conclude that all 3 technologies are useless.
And Wi-Fi would not reach the distance from my house to the house across the street, so unless I want to call myself it is useless
I bet I'll be modded down for dissing Linux, as always...
Spend a lot of time playing le Tux Racèr?
Huh.
Didn't you mean, "I would have been kind of annoyed if this was modded as funny, eh?"
What, like 8-12 more hours till kuro5hin's back up?
Oh, the humanity...
Can anyone recommend some good books on it - more overview stuff?
I'm serious - I'd like to read something good on it. I understand the basics - voice sent over IP, but want to read about whatever other abilities it has that makes it so damn complex. It seems pretty simple to me.
I guess a lot of the complexity comes from tying it into the POTS, but in my simple mind, a headset on a PC and some H.323/T.120/whatever spec it is software would take care of it on the client end.
Though it seems a lot of the stuff seems to be special network gear to tie it into the current POTS headsets. To me, someone could make a killing by just making a server with a PRI connector or two and client software. Sell headsets for $20 and profit.
Or am I really oversimplifying it?
I didn't know Canadians had heard about Linux yet. Thats nice to know that a good 100% American product like Linux has managed to drift North of the border and actually gain an Arctic foothold.
Canadians may be on top of the map, but they certainly define "bottom feeder" dont they?
I'm not trying to flame or incite flames, just trying to stay on topic and spread some truth where I can.

Three technologies that will live up to their hype
The bursting of the high-tech bubble a couple years ago sullied the prospects for new technologies--in some cases, for good reason. After all, many so-called tech revolutions haven't even come close to living up to their hype. Selling doodads on the Web is not an inexpensive way to make billions, and the malls are still jammed with shoppers. A new Web services economy, in which customized mini-software programs are licensed and distributed over the Internet, hasn't emerged. And remember convergence? Some of the tech world's highest flyers blew their brains out on that idea.
And yet, despite the many disappointments to businesses and investors alike, it's a mistake for either group to think the high-tech meltdown whitewashed the economic impact of all technological innovation. It's just that business models don't change overnight. So although the volume on the hype machine is now a faint crackle, there are some technologies once labeled "disruptive" that are entrenching themselves, if only quietly, in corporations and society at large. And the opportunities remain significant.
Broadband wireless data communications is making instant access to information anytime, anywhere, a reality. The open source movement, which encourages the free exchange of software for the Linux operating system, is transforming corporate IT departments. And the venerable phone is now tapping directly into the Internet, nearly eliminating long-distance fees and threatening upheaval in the telecom industry.
You may not be aware of it, but these technologies are here, they're being used by Canadian companies--and they may yet live up to their billing.
Wi-fi
When Starbucks announced in January 2001 that most of its outlets would offer wireless broadband Internet access to their frappuccino-addicted customers, skeptics questioned its plan. Turns out Starbucks was ahead of its time: the chain now has thousands of wireless cafés across the US, and space on the Wi-Fi bandwagon has become scarce.
Wi-Fi--short for "wireless fidelity"--is the palatable brand name for a standardized (802.11b) wireless data signal that broadcasts 11 Mbps of bandwidth within a 100-metre radius. Put the transceiver inside a building, and the distance of that wireless local area network, or wireless LAN, is reduced by as much as two-thirds. But that's enough for most eateries, hotels and airports that want to give patrons a wireless Internet connection inside a so-called hotspot. All users need is a Wi-Fi modem card or a built-in Wi-Fi radio like Intel's new Centrino chip.
If you believed the hype about 802.11b three years ago, you're no doubt disappointed that our cities aren't yet awash in wireless broadband signals--but that future's not too far off. The buzz has been loudest in the US, where Cometa Networks, an ambitious venture backed by IBM, Intel and AT&T, has vowed to launch 20,000 hotspots across America by 2008. Both wireline and wireless telcos are making a big push this year: Verizon is converting some 1,000 New York City phone booths into Wi-Fi hubs--an idea it got from Bell Canada, which is wrapping up its own six-month trial of public Wi-Fi service (branded "AccessZones") in train stations and airports across the country.
Independent and regional wireless ISPs are coming out of the woodwork in both the US and Canada, partnering with any establishment that wants to provide a value-added service. One start-up, Spotnik Mobile, has 49 public hotspots in Ontario (mostly in Toronto, where the company is based) and plans to have 500 by year-end. Spotnik's business model--which drew a $6-million investment from Telus--has the company making deals with the hospitality, transportation, property management and food services industries to set up hotspots. "We see it as a marketing tool for customer acquisition," says Murray McCaig, who co-founded Spotnik with MBA school chum Mark Wolinsky in 2001. "We drive traffic t
If I could go to a coffee shop and work on my master's thesis, I would, but for that, I would need a laptop, which I don't have enough money to buy. The people most lured by online-coffee shops, I think are students. Most working people would rather stay at home after a hard day's work, or would prefer to stay away from a computer, while enjoying a quiet evening, at say...a coffee shop.
Ofcourse, I'm not against perpetual connectivity, which Wifi promises to offer, but you can't expect a majority of people to actually sit at a coffee shop just to finish their work (this leaves out some students).
We should (or will learn to) treat Wifi as an ever available commodity (like pay phones are) but not one which we expect people to use 24/7. That is simply asking for too much. Wifi will catch on when it's time comes.

In my city (~50 000 residents) we have one of the largest call centres in north america. For those of you who don't know, its telemarketing.
:-)
At any one time, there are 500 people actively dialing on the floor, and all are using VoIP for their outgoing call. It's quite amazing the network set up they have, as the only problem they ever seem to have is people knocking out fibre lines via car crashed

It's too late in the day - i'm an idiot.
Canadians have known about Linux since its inception. When RMS laid the first lines of code down for the kernel, it was the Canadians at the U.of Montreal that were the first to pick up on the GNU code (it's a pun!)
GNU and RMS are singlehandedly waging the war against Microsoft and proprietary software in America, but Canada is doing it's part too in North America.
So in summary, your post was on-topic, but it was incorrect.
Construction begins July 8 to reconstruct I-10 interchange at Maricopa Road
July 8, 2003
A $12 million project to reconstruct the Interstate 10 interchange at Maricopa Road and widen sections of I-10 near Maricopa Road will begin this week.
I-10 will be narrowed to one lane in each direction at Maricopa Road on Tuesday night (July 8) from 9 p.m. until 5 a.m. while crews install temporary concrete barriers to establish work zones for the bridge construction.
The construction project will build a new bridge to carry Maricopa Road over I-10 and reconfigure the freeway entrance and exit ramps at Maricopa Road to a diamond interchange, eliminating the current cloverleaf ramps.
Starting next week, crews will begin excavating dirt and building piers in the freeway median for the new Maricopa Road bridge over I-10.
The alignment of Maricopa Road will be altered as part of the new bridge and ramp construction. Maricopa Road will be built across I-10 at a 90 degree angle, meaning drivers will travel straight over I-10 instead of using the existing diagonal bridge crossing.
Maricopa Road will be realigned on the east side of I-10 to connect with Sun Dust Road and Nelson Drive within the Lone Butte Industrial Park. A new connection from Maricopa Road to Wild Horse Pass Boulevard on the west side of I-10 also will be built.
The project also will expand I-10 from two lanes to three lanes in each direction at Maricopa Road to better accommodate traffic entering and exiting the freeway. Crews will remove approximately two miles of the existing asphalt roadway and pave the freeway with concrete.
Pulice Construction, Inc., of Phoenix is scheduled to complete the project next spring (2004).

Now that we know the last five characters of the data segment of every wifi packet will be ", eh?", it should be even easier to get those keystreams...

A portion of the transmit audio is also mixed in to the receive audio. If you don't do this, people think the phone is broken. Analog phones do this by unbalancing the hybrid that separates transmit and receive audio.

WiFi usage must have really taken off recently. I was visiting Canada only nine months ago, visiting an old girlfriend who I had met while at University. The purpose of the trip was to meet her family and spend thanksgiving with them.
I arrived in Toronto airport with my trusty 17' TiBook and wanted to check my email but couldn't find any open AP's. Well I thought to my self, "fuck you asshole Canadians", rebooted my laptop into Gentoo and opened up Kismet, one of the private nets was very hight traffic and it only took a matter of hours to pick up enough packets to figure out their password. I had the time while I was waiting to be picked up, they were caught up in bad weather.
So anyway I was in the network, which was mostly running Windows.
I was amazed at what I found, it looked as though I was into British Airways private network, there were some machines that I could not access but the majority were unpatched Win2k servers with IIS running. At this moment I felt a slight tingling in my pants and a couple of seconds later a full blown erection. I considered for a moment what havoc I could cause, I decided it would be funny to steal these whore chekout sluts' hotmail passwords and send fake emails to their boyfriends. I'm jelous and if I being a GNU/Linux hippy can't have girls, these football team captins should not either.
This is how I executed my evil plan:
An added bonus was that these Win2k servers had publicly accesable IP's so I jotted them down and when I got home set up SPAM sites up on their ghey boxes, just search google you will find many stories about when they found out! OMG LOL WTF!!!!1

You know when you've got a double negative way up in the article's lead paragraph, that what you're about to read is gonna be slop.
When Starbucks announced in January 2001 that most of its outlets would offer wireless broadband Internet access to their frappuccino-addicted customers, skeptics questioned its plan. Turns out Starbucks was ahead of its time: the chain now has thousands of wireless cafés across the US, and space on the Wi-Fi bandwagon has become scarce.
How exactly has space on the Wi-Fi bandwagon become scarce? And even though Starbucks has thousands of wireless cafes up and running, what kind of profits, or losses, are being made? We don't get any kind of analysis here, because the article just breathlessly jumps ahead and asks this question:
How much are people willing to pay? Can the many service providers work out access-sharing agreements with competitors so consumers don't have to shell out for multiple accounts?
Sorry, but that's the wrong question to ask. The question isn't how much people are willing to pay. The question is if they're willing to pay at all. I suspect that Wi-Fi will be the ultimate loss-leader for businesses who profit when their customers linger. Lose money on the Wi-Fi; gain it back by selling an extra $2.00 coffee. But again, the article doesn't even bring up this idea. Instead, we get:
These details should be sorted out in the next year or two, and consolidation is pretty much guaranteed. Once that happens, Wi-Fi will be even more widespread than a certain chain of cafés.
Sure, but will Wi-Fi still even be available at that certain chain of cafes? Will a large enough portion of paying customers keep Starbuck's network financially viable? See, for instance, the rather sobering third item published a couple months ago on this page.
I use a wireless network all the time. It's truly a useful and earth-shaking technology. Which makes it galling to see such a superficial analysis of its vast possibilities. There's no doubt that Wi-Fi will produce amazing changes in how we live and how we work, but the author of this article did a terrible job of backing up his suppositions.
I'm generally "Interesting," "Insightful," and even "Funny" here. What the hell happens to me at parties?
Yeah Canada! In your face! (But in a nice way)
And, of course, I use Linux for all serious tasks on my home network. Gateway, router, DNS, email, desktop, printserver. I have a couple of Winboxen for lite gaming, but that's it. Still trying to get Linux in the door at work. I know Citrix runs on Unix, but does anyone know if it has a Linux port yet?
You are not the customer.
I work at an insurance company, with offices in the US, and VoIP has been in use for a while now. I won't profess to know too much about it other then the fact that it's there, but it does save a lot of money for the company. This could all just be hype created by my bosses, but they've been giving us a couple of perks lately. We don't get perks normally. Hey...if it get's us perks, then I love it!
lighten up, eh?
There are a ton of reasons to use wifi in a coffee shop, much less anywhere else. Perhaps you should learn to treat wifi as a powerful tool which people can use 24/7. It is not too much. Wifi has alrady caught on, and begs for others (like yourself) to get onboard.

Linux and WiFi make a great combination.
Here's a HOWTO (soon to be published at the Linux Documentation Project) about using Linux as a WiFi Access Point.

Heh, this article is somewhat apropos for me. I just returned from Montreal, where I stayed for ten days in a condo. I brought my laptop and wireless card with me, thinking I might go to a hotspot and check my mail.
As it turns out, I had access to wireless right in the condo. It wasn't exactly a very strong signal, but it was good enough to surf and check my e-mail.
I noticed that the poor bastard that was running it happened to have the same wireless AP (an SMC Barricade) that I have. On a hunch, I checked the web server it runs, and he hadn't even set a password!
Had I known where it was coming from, I would have told them about it. As it was, my French sucks, and I didn't feel like knocking on a bunch of doors trying to explain wireless security. At any rate, they hadn't set up their timezone properly, so I did that for them....
That's a first! (I know, I must be new around here.)
Nighttime construction on State Route 51 will close the freeway's northbound lanes between Highland Street and Colter Street starting tonight. The Arizona Department of Transportation (ADOT) says northbound SR 51 will be closed between Highland Street and Colter Street tonight (July 8) and Wednesday night (July 9) from 8 p.m. until 5 a.m. each night while crews make drainage improvements. Drivers should use 16th Street as an alternate while the freeway is closed. The following traffic restrictions on SR 51 also will occur tonight (July 8), Wednesday night (July 9) and Thursday night (July 10) from 8 p.m. until 5 a.m. each night: ~ Northbound SR 51 will be narrowed to one lane between Thomas Road and Highland Street. ~ Southbound SR 51 will be narrowed to two lanes between Shea Boulevard and Northern Avenue. ~ Southbound SR 51 will be narrowed to one lane between Bethany Home Road and Thomas Road. The westbound I-10 ramps to northbound SR 51 and eastbound Loop 202 will be closed Wednesday night (July 9) and Thursday night (July 10) from 8 p.m. until 5 a.m. The construction work is part of the $75 million SR 51 project to add HOV lanes in each direction between I-10 and Shea Boulevard, higher sound walls, rubberized asphalt pavement and operational improvements to the freeway. SR 51 construction information is available at www.SR51.com or by calling the project hotline at 602-248-3098. Ames Construction, Inc., of Burnsville, Minnesota, and Edward Kraemer and Sons, Inc., of Phoenix are scheduled to complete construction next spring (2004).
Having recently gotten electricity up here, VoIP is a very nice touch indeed! Now we can communicate between igloos much more easily.
Life is good.
Watch out, boys.
Just wait and see what that high Canadian dollar, inflation, SARS and BSE will do to the Canadian economy. I've lived in both places (US and Canada) and I can assure you that quality of life can be as high in the US as in Canada, if not higher. Plus, there is an imbalance in the Purchasing Power Parity which basically makes Canadian goods much more expensive than their US counterparts right now.
ever seen a michael moore documentary? 'nuff said.

Three words: Big fat deal. Maybe even a hairy one. Instead, combine cheap Linux-based routers (you could of course use just about any open source operating system.) Do mesh network routing. I don't know how to do that part but I'm sure some people have some ideas.
This would be the equivalent of Al Gore's Information Superhighway being replaced by homebuilt skycars running on biodiesel. Land links will always have their place but if we can come up with ways to route traffic around through multiple links simultaneously (possibly with some redundancy in the longer trips) then I think the wireless mesh network with few links to the current network can still be fast. There is of course always room for being able to pay to use some kind of high speed link, I would certainly be planning to have some kind of flexible access control. And you can have any kind of backup network you like, of course.
Anyway I also need not belabor the point that this is a way to get VoIP. Provided you have some reasonably reliable links near you (people on UPSes connected to DSL would be excellent, or commercial sites with faster connections and ups + generator, etc) you can be fairly certain that as long as you provide power to your equipment, you can get access. People in remote locations can do point to point links over distances as great as two miles and still get over a megabit of bandwidth in each direction.
Imagine using waste on a network like that. It's a litlte bit like heaven, isn't it? When are we getting a fup on waste?
"You're right," Fisheye says. "I should have set it on 'whip' or 'chop.'"
I've rarely seen it where I was in the US. I've lived in California and rarely did I feel unsafe. Most of the time that type of crime is pretty well delineated into good areas and bad areas, and mostly from folks who are involved in illegal activities (e.g. drive into East Palo Alto at night...not smart...). In fact, back in Edmonton, Alberta, there is a lot of gang violence and a lot more home invasions than I ever remembered in the Bay Area.
As far as Michael Moore goes, I think some folks need a bit of a reality check.
"Imagine using waste on a network like that. It's a litlte bit like heaven, isn't it? When are we getting a fup on waste?"
Hehe. Always notice how geeks want to use your equipment, and connection? Instead of the technical aspect of mesh networks. Why not address the people part of it? Why should they be alturistic towards a complete stranger with unknown intentions?[1] Especially when they will be the ones who take the fall for any mischief that happens on their network. There's a reason people rarely pick up hitchikers anymore.
[1] And I haven't even gotten into the resource abuse angle. Let's see how much we can push this T1?
VoIP and WiFi make a great combination, too. They, together with 3G, make near ubiquitous communication?
The telecoms seem to be more conservative on the VoIP and Wi-Fi. The telecom guys think in different way from Internet people. I worry the traditional telecoms may obstruct the development of Internet telecommunction.
A very interesting read, since I'm researching the possibilities of WiFi (802.11g). Because a friend of mine wants to use WiFi to supply his village in Hungary with Internet access.
Once we have a working plan, we can reimplement this truout his country. And maybe even implement it to supply Internet access to hard to reach areas in my country (Holland).
Success stories like these only help us with the exceptance of our idea, and possibly even help to get (more) investors/sponsors.
So when do we get voip over ipv6 over wifi under linux?
VoIP technically would mean that some segment of the path between the two end points traverses on IP or maybe some form of packet or data networks. (say ATM frame). There are what are called Next generation end points like SIP phones that use IP network (or data networks) throughout. There is no traditional class 5 anywhere in a voice call between two SIP phones. Then there is what is called tandem replacements where the class 4 switches are being switched with what is called a softswitch and a media gateway that converts cicuit voice to packet till the class 5 at the other end. In this case the last mile is still the same. So the investment in the class 5 is safe and VoIP solutions dont have to contend with the five to six 9 reliability the the class 5 switches provide today. Then there are solutions like VoB (or voice over broadband) that uses VoDSL technology. Now here again the calls would by pass the 5E in the sense that it goes with packet traffic that passes through a DSLAM (DSL access multiplexer). All these options are at various stages of trial and adoption and none of them is a success. Now what does all this mean? It means that when somebody says VoIP is a success, it is understood differently by different people as VoIP as a business is still not defined in a standard way. If somebody says that carrying voice on data networks in part or in full is successful I would say it is premature to make this statement. Even today more than 99 % of voice data passes through pure voice/ss7 controlled networks (though SS7 is a packet network). So what can be said is that VoP (Voice over packet) holds promise which has been said before and with that I agree. my 2 paise. shak
(Just wanted you to know that some of us do agree) :)
You probably also think that if something doesn't have a price tag on it, it's free for the taking.
Just because something's not marked PRIVATE doesn't mean it's available for everyone to use as they please.
When you refer to a "Texan" accent (there are many) do you mean like GWB or Dr. Phil, or something else?
My other car is a 1984 Nark Avenger.
Just don't think of it as a double negative. You can do that by thinking of "inexpensive" as synonymous with "cheap" as you suggest. Is that really so hard to understand?
And as for the article's content, they didn't give actual figures where it wasn't necessary. Figure that one out. It's not that hard.
