WiMax Is A Huge Success! No, It's Dead! It's A Success! It's Dead!
from the wimax-extremism dept
Back in November, we dinged Intel for the silly assertion that WiMax was a big success when no WiMax actually existed (despite the stories you might have read in the press). WiMax equipment was still in the certification stage -- and while that certification finally happened, it is still quite limited. The hype level concerning WiMax has certainly gone to ridiculous lengths, and it's too bad that so many seem to have fallen for it. The "WiMax" networks that the press talks about are almost entirely not WiMax, but some proprietary technology that the vendor hopes to maybe someday upgrade to WiMax, if possible. Still, with all of that, it's fairly amusing to see Qualcomm's latest statement that WiMax is dead. Of course, just as Intel is biased because they've bet so much on WiMax, Qualcomm is biased because they've bet so much on WiMax competitor FLASH-OFDM. Honestly, though, is it really so hard to wait until the technology is actually tested in a real environment before we declare it dead or a success? The "extremism" over WiMax doesn't do anyone any good, and is only going to lead to more false expectations concerning the technology. Unfortunately, it seems like recently "false expectations" are what the wireless industry has been best at delivering.
Thank you for reading this Techdirt post. With so many things competing for everyone’s attention these days, we really appreciate you giving us your time. We work hard every day to put quality content out there for our community.
Techdirt is one of the few remaining truly independent media outlets. We do not have a giant corporation behind us, and we rely heavily on our community to support us, in an age when advertisers are increasingly uninterested in sponsoring small, independent sites — especially a site like ours that is unwilling to pull punches in its reporting and analysis.
While other websites have resorted to paywalls, registration requirements, and increasingly annoying/intrusive advertising, we have always kept Techdirt open and available to anyone. But in order to continue doing so, we need your support. We offer a variety of ways for our readers to support us, from direct donations to special subscriptions and cool merchandise — and every little bit helps. Thank you.

At the end of the day, once the networks are deployed, the provider will still have to acquire and provision customers, bill and settle, provide complex customer support, and provide strong content management.

Re:
It definitely solves some problems... if it works and if it's cheap -- which may or may not be true.
Also, there are other wireless broadband technologies out there other than WiMax and some of them seem further along.

Re: Better, less corporate, next gen. wireless tec
What?!? You can't be serious. We've written about xG a few times, and it's *really* questionable. The only people who say it works are people who are paid by the company and nothing about the technology has been revealed.
Until there's actual evidence of how the technology works and what it really does, I'm sorry, but xG remains in the "not real" category.

How would it work?

IEEE Name Change
Ask - anyone who knows a lot about Wimax (I am not one of them) and they all will agree that the word has been distorted beyond belief.
Wimax is following the normal technology perception curve, right now it is peaking - soon it will fall into the valley of technology disillusionment to either slowly claw it's way into the mainstream or quietly go away (like ISDN).
As for xG - anyone who write that something needs more 'hype' clearly has an agenda. More 'attention' might had slipped pass the B.S. filter. Do these guys make little cell booster stickers for the back of my phone too?

WiMax vs. FLASH-OFDM

Re:
I will answer both questions for you......NO! You or nobody you know has used WiMAX extensively so you have no way of knowing anything you just stated other than from the HYPE YOU YOURSELF ARE DEFENDING! You are part of the problem. I can tell you from an engineering point of view that there is no way WiMAX will meet the expectations set by the HYPE machines. NO WAY without violating the laws of physics. The range and performance will be disappointing, the limitations (have a tree between you and the tower maybe?!) will also be a let down. For sure I would only expect maybe have the range they are claiming. Maybe less if you are assuming a very stable reliable signal.
You will just have to trust me on these statements because there ARE NO LONG TIME USERS and what people are using pre-WIMAX are not in sufficient numbers and have not had it long enough to get a statistically significant feel for the reality.
Oh sure, it is an improvement over WiFi which is not a hard thing to do. Just don't expect too much and you won't be disappointed.

Regarding WiBRO for TIM
In April, there were two pilot projects.
Now, WiBRO is NOT WiMAX. Just because the two share some core technology does not make them the same. The key to a standard is that things need to be almost EXACTLY the same so that they can INTEROPERATE. That means you can take equipment from one vendor, and use it with equipment from another vendor. This is what makes standards work in the market, because vendors that adhere to the standard can sell compatible kit. That means customers can buy whatever, and it will work. Carriers like it because they are not locked to one vendor, and thus vendors need to compete for business, so prices go down. Plus, with everyone using the same standard, volumes for components go up, and prices come down. It's the whole virtuous circle.
There is a lot more to this than just sharing technology like WiBRO and mobile MAX. TDMA cell phones and GSM phones share essentially the same technology, but the two cannot interoperate. You can't put a TDMA phone on a GSM network or vice versa. The little nagging details of standard specs, adherence to the spec, and testing prove to be dramatic hurdles.
So while WiBRO is a standard, it is NOT WiMAX. But the IEEE may just see it as the only working thing close to WiMAX, and eventually decide to call it WiMAX if their own version stalls out. That has not yet happened.
Next, how is WiBRO doing, since I have the benefit of writing this three months after you. Well, quite poorly, as one would expect of a new standard. There is only one PCMCIA card type available. iRiver, who was to make a mobile media device, has announced they have not been able to get it to work yet. Samsung, who was to be selling the only WiBRO handset for the pilot and launch, has recalled their latest demo units. Apparently there is a problem with the phones getting very hot.
So, just one terminal device available for use. How does it work? Well, apparently KT packed a bunch of execs and press in a bus in Seoul to show them streaming media as the bus rolled around a few blocks of Seoul where the pilot network is deployed. Unfortunately, the press go to see the demo fail miserably, as a connection was only established successfully after the bus had finished the tour. KT said, just go in the expo center and see our demo in there.
SKT and KT have pulled back their build-out schedule, and are only continuing the footprints of their pilot networks. SKT is only operating six "hotzones" around Seoul college campuses.
According to press, inside the same trade show, KT was demonstrating WiBRO video, but could only achieve a 50Kbps downstream rate.
So, while this is all very damning. It could be that it's just normal for an immature technology. But for now, there is no mobile WiMAX, and the WiBRO that does exist is very poor.

xMax
[ link to this | view in thread ]
Re: xMax
xG claims a huge range for xMax but it's based on this one highly unrealistic demo. Put WiFi on a 200m tower above flat open terrain and it will go very far too.
I.e., xMax probably "works", but definitely no better than the alternatives, and probably not even as well.
Disclaimer: I work for Qualcomm, but I did this on my own. If you don't believe my numbers, check them yourself or ask some professional communication engineers.
