WiMax Formed To Promote 802.16 Standard
The Original Yama writes "Intel, Nokia, Proxim, and a bunch of other companies have launched WiMax, a non-profit group founded to certify and promote the IEEE 802.16 wireless networking standard. What's interesting about this standard is that it allows "up to 31 miles of linear service area range and allows users connectivity without a direct line of sight to a base station," all at a shared speed of 70Mbps. This simultaneously blows away 3G mobile and 802.11 technologies."

Yeah. Damn. *31 miles* of users sharing 70Mbps.
Heck, I'll whip out my trusty ol' 56k modem and get better performance.
May we never see th
With Nokia in there, does that mean their phones will somehow be able to use these networks to make calls?
See here.
Does this seem like something which could be used as a replacement for DSL/Cable in areas where there is none? I personally live in one, .5mi out of range from Cable. So, the 31mi range is most likely more than that of DSL and/or Cable. So, while it is slower, this does seem like something which could be used to replace and/or suppliment DSL/Cable.
How long until there's a true standard with every company using different types? I really don't feel like taking 14 different wireless network adapter cards with me everywhere I go to have internet. .11a, .11g, .16, .11b, WHEN WILL THEY CHOOSE SOMETHING?
Imagine the next generation of AirPort:
Apple builds 802.16 into their future laptops and iPods, and partners with one of the nationwide infrastructure providers of 802.16. Then they offer "get-online-with-your-Mac-anywhere" service, and iPods can receive internet radio, wherever they are. That would be pretty sweet.
Sounds great, but 31 miles? How about 50 feet though wood and concrete? Line of sight is nice, but for most interesting home networking, there's just no way.
This simultaneously blows away 3G mobile and 802.11 technologies.
802.16 is designed for fixed outdoor operation and the antennas are much too big to fit in a PCMCIA card, so it won't replace 802.11.
802.16 clients can't move around, so it can't replace 3G.
Obviously if you have a dense population of users it becomes economical to have more base stations in the 31 mile radius, each serving a smaller zone, in the interests of extra bandwidth per user.
From the article, this technology is meant to link 802.11 hotspots, not as a replacement to 802.11.
Free space optics is another interesting field that will give you upwards of 1Gb/s over 2km. More info on free space optics.
All of these technologies are emerging to try to link the last mile to the high speed backbone as the cost of fiber is prohibitive (~$325/m) and the majority of the US doesn't live on top of a fiber backbone.
For those whom are not aware of this technology, I gladly provide the following linkage:

At this stage, to CHOOSE SOMETHING means to give up on technical progress. It is proper to ask for interoperability, so that new wireless cards speak several protocols, but it is stupid to ask the engineers to stop working on improvements.
I'm assuming it's 70mbps/channel. But for 31 miles there had better be a lot of channels. Could you imagine 9,500 square miles (pi*31^2) of people all sharing the same 10 or so wifi channels? It could suck.
autopr0n is like, down and stuff.
I'd take decreased range (5-10 miles) and 100mbit/s thank you very much. Screw that whole "backhaul for 802.11x" crap, you know you'll have end users trying to hook into it. I think it'd be great for universities. One or two WAPs and you're covered. As long as people arent trying to use Kazaa from their psychology class you're OK.

If you're not outraged, then you're not paying attention.
No joke. Why can't they find something that's completely functional and works and then, oh I don't know - stop for a while? I'll never go wireless at this rate.
did you read my post? Choose something to make public. Develope for at least a year, then release something else. Releasing incompatable products whenever you create them is gonna screw up the world. All these blue laser DVD type things are gonna screw up the world also with 5 or 6 companies making their own.
At $10k for a base station and $1k ($300 eventually) for the reciever, this tech is still a bit off. However, improvements like this will be what eventually let wireless give DSL/Cable monopolies a run for their money in the last-mile competition.
Bring it on. I'm tired of 56k. Anybody know the latency on one of these connects?
What's really interesting is that it is only 25 miles to a typical horizon. 31 sounds like marketing hype to me, since it would be useless unless you're dealing with relatively non-terrestrial points-to-point.
regular - for 10-55GHz frequencies and that one actually gives even up to 134Mbps. Now, because it uses range-dependent modulation techniques, you'll not have 70Mbps @ 30 miles. At 30 miles you might have about 20Mbps
somewhat limited - for 2-11GHz which is unlikely to be implemented because it runs into almost all possible licensed frequency bands
unlicensed - for 5 GHz unlicensed band - exactly the same as 802.11b
Now, in any case, this is a fixed wireless network - that is stations are not mobile. So, it's NOT a competition for any mobile standards. All of that is very questionable at the moment because it will require quite a large licensed band and unlike UWB, it will transmit at measureable powers. I don't think Nokia would do anything to kill UMTS and 3G.
There are some ISPs using it: installation cost in one I know is around $700 and monthly cost is $40 for wireless T1.

Yeah especially in a city like New York or LA. It'd be faster to walk to the site to read the information then use this. I'm hoping there are multiple channels.

I still think microwave T1 is better. For instance, Lick Observatory in the hills behind San Jose is linked to UC Santa Cruz by a line of sight microwave T1 connection. I would trade a non-requirement of line of sight for speed/distance any day.

if tehy had 2 towers in the service area, would taht give twice the bandwidth to the customers?
not nessisaraly by way of taking one pe4rsons traffic and sending it to 2 diffrent towers but is it not possable to assign half the customers to one tower and half to another and give each twice the bandwidth?
if yu can then this would basicly make bandwith increases a heluva lot easier.
I am the Alpha and the Omega-3
This sounds great! I have been planning on setting up 802.11 for a while now and getting better range and bandwidth would be cool.
...
But it seems this is just speculation. I couldn't find any products that provide 802.16, at any price. Until we have products available, I'm going to call this pure speculation. Perhaps the final products will have a bandwidth of 7Mb instead of 70, a range of 2.7 miles instead of 27 miles, and then there is the cost, with 802.11b now under $100 per node
Imagine an ad-hoc cluster of these..

Wireless technlogy is progressing at 1.7x the speed of Moore's Law - pretty amazing.
Look at what is already available from places like Vivato, Motorola (Canopy) and Proxim - and this is *just* the beginning - wireless technologies weren't a serious factor just 5 years ago.
Add in cogntive radio, software defined radio, ad hoc and mesh networks, etc., and you have a wirelss technology juggernaut forming that is unstoppable.
Of course, the solutions will keep coming, and there will be confusion in the market, but that didn't stop the auot, the PC, or the digital media.
We will look back in 20 years and be amazed!
Bring us inexpensive highspeed networking!
Last year I witnessed a 928Mhz spread spectrum link over 10m miles using 2 yagi antennas that was a) line of sight with no packet loss a 9600 baud, b) inside a concrete block building with no line of sight and no packet loss, and c) inside the same building but behind a huge diesel engine with about 5% packet loss that required a number of retries before getting through.
If this technology can achieve the same throughput at mbps speeds this will be a sure winner.
what the hell. the bullshit parent comment just got a +5.
all he did was copy and paste from a google search of "802.16" where coincidentally his links are the 5th, 6th and 7th links retrieved, in the exact same order.
i doubt he even read those articles.
give that karma whore what he deserves.
What a shocking number of people seem to be missing is that these are for different purposes! It's like asking why the roads have both cars and trucks on them.
The 802.11's are for wireless LAN. Local area net. They are a replacement for/supplement to ethernet. The various sub-standards do differ, that's true... but they are to serve different purposes (different levels of trade-off in price/range/throughput), and as far as interoprablity goes, that is supposed to be one of the purposes of 802.11g.
802.16 is for wireless MAN. Metropolitan Area Network. That is actually somewhat of a new concept. It is something like a replacement for cable modem/DSL or for T1's, but it's not really the same as either. It is supposed to be a cheaper form of high throughput last-mile delivery.
Despite many very cool attempts made over the past year or two, 802.11 is not particularly suited to delivering the last mile. It's fundamentally only good for a small number of computers over a short distance. That's a fact about the construction of the media access control layer and the radio spectrum. However, it does make for a much cheaper and easily configurable network. You wouldn't want to waste the money on more expensive radio equipment and spectrum in order to carry signals over a mere hundred feet to a handful of computers if you can do it cheaply and easily without.
Anyway, I think that 802.16 is just tremendously cool. Cable modems are neat and all, but anything to increase the competition in the last-mile space is great. Another thing that I would really like to see come about is a grassroots mesh network of 802.11. Just simple folk who share their cable modems with one another. You can route to mine if I can route to yours. That sort of thing. Anyway... getting off topic.

Not an editor command: Wq
the parent poster just did a google search of "802.16" and pasted links to sites he thought sounded suitable. the sites he linked to just happen to be in the same order as they are listed on google's search results and the second link doesn't even have anything to do 802.16 technology.
give this karma whore what he deserves.
Are there any ISPs using such fixed wireless technology for access to residential customers who can't get access via DSL or cable? Is there a site which lists them? Are there any in the Western NewYork region? :-) (just thought I'd throw that last one in there).
yup, here it is. again.
Ok, so why not boast 52.67 miles....or 74.38 miles....gee, maybe because they are all as technically meaningless and misleading as 31, thus the obvious hype, which you, among others, are so willing to swallow.

One difference between 803.11 and 3G technologies, apart from the obvious physical layer, is that 3G spectrums are licensed property, and would require permission from governing bodies for access to the specified frequencies and channels.
WiFi, on the other hand, resides on the unlicensed 2.4Ghz spectrum. Therefore, it lacks the lawful enforcement of any usage for the spectrum.
With this lies the problem of billing. Even though hotspots are booming all over the world, one day access providers will realise that they cannot provide internet free forever, and would need to charge for WiFi access (this is already true in some airports). However, some business (i.e. cybercafes), use WiFi as a tool for attracting customers; but they still have to charge for the coffees!
Now, WiFi won't die because of the lack of billing and charge systems. It is _designed_ for home and office use anyway, as a wired LAN replacement. Wifi can still be used in the closed premises to share the internet we already have (i.e. ADSL) to our users in our network (our employees and family).
Question is: now that this 802.16 is used for MAN (metropolitan area networks), how does it fit into the current situation of these wireless networking standards?
Would control be in governing bodies to grant access rights to use certain frequencies (just like in 3G)? Or would it be like WLAN's where nobody has control over the frequencies and everybody can use as they like?
If the latter is true, it could provide good competition against 3G and 803.11a, but how can access providers gain control over the use of a certain frequency in a certain area to provide internet services?
Like I said, you seem to be getting worked up over something pretty trivial.
What if it's 31 miles because that's the limit of the technology? (i.e., even if you have a really high tower, the signal peters out at 31 miles.)
In any case, I don't care all that much. So good night!
I would love to see them put a few towers in my area, I can't get DSL or cable (TV, let alone internet) so something like this would be ideal for a sparsely populated rural area like mine.
Are you talking?

/. that means it's forgotten.
Okay, so the previous article had "Intel" in the title, but it covered the same ground. Five days ago. I guess on
And what I said there is still true. 802.16 is a technology spec, not a frequency band. Long range and high speed are for licensed users. Unlicensed users get short range (5 GHz band). And the 25+ GHz frequencies are very sensitive to rain fade. Even with high licensed power, most non-desert areas will have noticeable outages several times a year during strong rain on any link over 2-3 miles.
No, he's singing! Glorious lilting song! La la la!
What a piece of nonsence. Imagine RF antenna and a XX-century radio receiver. Sure it's not digital, but it's pretty simple.
Plain old sigh.

But can it be expanded with multiple cells? The article is notably light on technical details, and I'm not sure its safe to assume you could install 4 of them in a 31 mile radius without interference.
Even so, this would be a great technology for rural areas and countries that lack infrastructure.
You are in a maze of twisted little posts, all alike.
I hope this makes it... I would sure love NOT 56k modem access. Because we are not getting cable or dsl anytime soon and I'd have to sell a couple of kidneys for satellite. I like living in the country... hopefully this will make it a whole lot better... but by the time this would ever make it we'd probably get dsl or something :\

The encryption, etc.. are all nice, but this is a high-speed protocol designed to work with high gain fixed antennas pointing at each other, and not a sucky little 3db patch antenna on a laptop.
--Mike--
The protocol differs from WiFi.
802.16a has a polling model. Also has hooks for a MESH algorithm.
WiFi (11a and 11b) have a collision detect / fallback/retry model (lots of wasted packets when things get crowded).
A weird thing is happening on the WI-LAN (key technology leader in 802.16a) stock boards. Posters are suddenly ranting with anti-American war sentiment & rhetoric, effectively stifling intelligent discussion.
I have been in several situations thus far where I had no choice but dialup
Well... you have been in several situations thus far where you have had to choose between dialup and waiting to use broadband.
I'd still bet that if, in some alternative reality, you were banned from using broadband, you wouldn't stop using the internet.
