How long till we get 100M Wireless Networking?

[MadAd]

Correct me if im wrong, consumer units are up to about 20M with the g standard (ok, so we might actually get 10-15M in use) but what about 100 and above?

Is there some limitation to how much can be sent thru the air or is it just a case of wait and it'll come eventually- if the latter, what would be a ballpark guess on how long?

Thanks to anyone that can help

Netgear claims they already have with their turbo a/b/g products

In general there are limitations to how much you can send through the air but there are no simple "rules" for the maximum capacity. It depends on the frequency used, the distance you need to cover, how much power you are allowed to use, how hight bit-error rate you can tolerate and also how many people are using the "same" space, the last point is very important and is a major problem in third and 4th generation mobile communication.

My guess is that it would be difficult to go much higher than 100 Mb using the frequencies that are available today, at least not if you want the range to be more than a few meters. I guess this might change if more bandwidth is made available.

The way we use wireless today is retarded and idiotic. Wired hardware with wireless peripherals is the solution. I wish I worked somewhere where I could change the way we implement technology.

You could always just run two g links in full duplex, theoretical 108mbps. Crosstalk would probably be a bitch though.

How is that different that what we have now? The only thing that you left out on the wireless scheme is laptops. But seriously what is retarded and idiotic?

yes, the future is now. We do already have 100M wireless (Dlink and Netgear) 108 if you are picky. The real question should be how long until we have 1000M Wireless.

btw, there is really no limit on how much we can send through the air, after all we are sending signals at the speed of light (pretty close anyways) which is a little faster then through the wires, We run into the same problem as wire though with the speed increase and that is that the quality of the media begins to affect our maximum speeds.

 

[f95toli]

Not true, there is a limit but it is not directly related to the speed of light. As I have already written you are limited by the frequency you are using and also by interference since there are usually many users sharing the same frequency band (assuming you are not the only one using wireless).

I read somewhere that a new 1GB standard has been suggested that uses a frequency of 56 GHz, much higher than what is used today. I guess the problem is cost, microwave components that can operate above 26 GHz are VERY expensive.

Look at the quantity and the quality of the data being sent by the Mars Lander now, that Technology can be used here too.

just because the mars lander is sending beutiful pictures through space, that does not mean they are sent fast. It probibly take like 15 minutes to get one full picture. Also, a little off topic, But are the pictures from the mars lander only going to be black and white? why?

 

[nightowl]

The IEEE is working on a wireless standard that is supposed to have the speed of a 100Mbps switched LAN. Now, all of you who say we have 100Mbps wireless now are a bit wrong. I say this because you will never see anything over 50% of that bandwidth and in many cases less than that since the 50% is an ideal number. This is due to the overhead that is present in every wireless packet. Also, the 108Mbps implementations are not IEEE standards so compatibility with other vendors is almost non-existent.

A small antenna (slower and smaller bandwidth) that did not need to be extended was sending and receiving signals first.

Then they sent the command to open and fully deploy and extended a much larger antenna that handles much larger bandwidth and speed, it is now sending color pics back.

Edit: The 1st Antenna transmits at 11K.

The 2nd Antenna is transmitting at 128K. Not bad from millions of miles away, better than many homes here on Planet Earth.

With 1 gig lans out now, I haven't given wireless a chance or thought. I installed a wireless system in Poplar Bluff Missouri and at the time wireless was just too........complicated for a rookie to maintain. I got calls for the next few months over the same problems. Wireless is faster to set up but, in my opinion not as reliable as a good ol' direct connect cat6 or cat5 cable.

Im not bashing wireless! I'm sure it has more benifits than what I've personally experienced

Netgear and Dlink's SUperG and XtremeG do pretty much that...and yes, cross talk is RIDICULOUS.

browse the IEEE links ;-)

How about 430 Mbps Full Duplex, this type of equipment has been out for quite some time, just not in the consumer price range of course, I know I use equipment like this daily.

wow...I have seen OC3 laser Implementations, but I wasnt aware of radio'frequncy devices like that for sale...sweet.

Thank you all for a fantastic reponse, I now know a lot more about this segment, however I guess talking on board what is currently known, I should have asked how long till 200M, since (as nightowl correctly pointed out) the consumer units seem to be actually working around half of their advertised speed.

From the replies, it seems there is a way to go, but not too long if units are already in the offing - however if I may just expand the issue slightly;

1. How does latency factor into the increasing speed? Gaming is obviously the first target to benefit here- what are the expectations (in milliseconds) for any 200M (or higher) wireless units?

2. The 'how long' factor seems to be a bit cloudy still - would a year be too short? Two?


My interest is in home networking, or more precisely, intergrated cat5 - my application question is simply, is it still a worthwhile investment adding cat5 runs and wall sockets to a house, since with the wireless solutions gaining in maturity, home integration could be a thing of the past very soon? Mebee?

 

[f95toli]

pmallioux: Is that on a "free" band (=do you need a license) in the US and in Europe?
"license exempt in many countries" accoding to your link?

 

[pmailloux]

Yes this is on unlicensed bands at least in the US anyway.

Not until they start using something other than WEP in mainstream consumer wireless products

i have a netgear wgt624 wireless 108 router and a wag 311 card also from netgear. I connect almost constantly at 108. when i have others over or am over at other people houses who have d- link 108 they all work fine. The router actually gives good signal aways away from it.
