Why Some Enterprises Still Won't Buy Fast WiFi

As just about everyone knows, 802.11n is WiFi on steroids. It's much faster and travels much farther, making WiFi much more useful -- and even saving money by making it easier to cover larger areas with the same amount of hardware.

But even as as new research from TheInfoPro shows more and more enterprises jumping on the 802.11n bandwagon, the same research shows that some 40 percent of enterprises still show absolutely no interest in the technology.

That just floors me. I just couldn't understand why enterprise CIOs would snub such an obviously useful, stable, and affordable technology, so I asked Bill Trussell, managing director of networking research for TheInfoPro, what was going on with n.

First off, Trussell made it clear that 802.11n is enjoying a significant growth curve. Increasing wireless LAN bandwidth is the hottest data network infrastructure solution right now. He couldn't tell me how pervasive n was within the enterprise, but said 20 percent of enterprises are already using it in at least some areas, and another 40 percent are planning to do so. That includes new wireless installations as well as "rip-and-replace" projects involving earlier 802.11a/b/g systems.

But that leaves an unbelievable 40 percent happily ignoring 802.11n, even as consumers and small businesses embrace the technology as quickly as they can.

Why? What are they waiting for?

"By their own admission," Trussell says, "some organizations are deliberate late adopters." They want the prices to come down and the bugs to come out before they commit to a new technology.

That might make sense in many cases, but it's hard to see the logic in this case. The millions and millions of consumer 802.11n adapters and access points sold to consumers and small businesses have already driven down costs to only a slight premium over 802.11g equipment, and there's been plenty of time to discover any bugs. I haven't heard of anything in that area, have you?

So what are we left with? Being a late adopter for the sake of being a late adopter? Is that any way to run a business?

Re: Wireless
@zeppy

That's a good question. 802.11n has often been put forth as making it possbile for enteprises to go unwired, which can save big bucks on continually pulling cable, but I haven't seen that take off yet.

Re: Wireless
It does seem like a surprisingly high percentage of enterprises not interested in 802.11n technology at first, but upon reflection I think SaneIT nailed the reason. The great majority of work in these enterprises is still being done over the wired networks (and why shouldn't it be?). What is wi-fi really used for in most enterprises anyway, mainly guest and meeting room access, right? I wonder how many of those 40% of enterprises don't support wi-fi at all...

Yes, especially if there's no downside.

Wireless
I can't understand why an enterprise wouldn't want to be at the forefront of certain technoloy.  This new wifi is one such case where companies should stay current.  The arguement that a company wants the price to come down and for bugs to be addressed just really doesn't cut it for me.  Staying ontop of emerging technology should be a number one priority.

Re: Range, frequency, and performance
Is it possible that some companies don't really want employees to have more wireless bandwidth? After all, the only users connecting via a wireless network are running desktop clients. And the existing infrastructure could deliver enough bandwidth to access a file server or run a Web app -- but not enough to download high-res video quickly off YouTube.

But, ahem, nobody at work is wasting their time on that stuff, are they?

Range, frequency, and performance
There are several possible operational modes in 802.11n with their own pros and cons. To get maximum throughput and bandwidth with 802.11n you generally need to use only the 5.8Ghz band. However, using 5.8 exclusively will not support legacy 2.4 B/G clients. Also, higher frequency costs range -- 5.8 cannot go the distance or penetrate obstacles to the same degree as 2.4 (blame physics).

It is true that at 2.4 Ghz, 802.11n will get better range than earlier generation 2.4 networks, because of the use of MIMO to capture signal path reflections (some G networks use this too but it wasn't part of the standard). And of course 2.4 broadcasting will support B/G backward compatibility. But the cost will be throughput (possibly by half) compared to 5.8Ghz mode.

Re: Why go wireless
I actually know of one company that uses WiMax as a backup for it's broadband connection, and is considering using it as the primary broadband connection, ditching its T-1 entirely.

 

The company? J. Peterman, of Seinfeld fame:  See http://bmighty.informationweek.com/security/showArticle.jhtml?articleID=222000764

Re: Wifi 'Issues'
N does a much better job of penetrating both masonry and steel construction than did earlier Wi-Fi technologies.

N Rules
Like all the comments, but surprised that 802.11n in specific isn't getting more love. I'm not saying rip out your existing LAN or WLAN infrastructure, but whenever you are adding or replacing anyway, there's just no reason NOT to go n. It's not that much more expensive, it's perfectly compatible with what's already there, and when you do have an N infrastructure, the speeds and coverage are dramatically better than a/b/g, meaning you can use fewer access points.

And in many cases, companies may find that n peformance is good enough that they can stop pulling cable for new work spaces, saving big bucks on labor and construction.

And all the n equipment I've seen has been more forgiving and less troublesome than earlier wireless equipment.

 I mean, if you're going to be a late adopter on everything, then I guess that includes n. But if you're going to take advantage of ANY new technologies, n seems like a no brainer to me.

Re: Why go wireless
It's a combo of what SaneIT and JPoe said, a sort of cynicism that the next greatest thing isn't all that greater than the last greatest thing, and most organizations doing just fine with mostly wired networks, with the wireless room here and there. In the world of not just finite, but white-knuckle-gripped resources, and the maze of cubes, where employees are chained to their desks -- and when they do get away from their desks for lunch or coffee or smokes or shopping, want nothing to do with monitors -- WiFi doesn't make practical sense.
