Nothing is set in stone(or even drafted), but I think their is talk of widening bands of channels to be 40 Mhz. It seems thier are two camps, MIMO and WWiSE.
It should be interesting to see who gets IEEE backing.
802.11 n will use 802.11e (Qos) which introduces Direct Link Protocol (DLP). This allows station to station transfer. Currently in infrastucture mode you can only communicate with the access point, when MIMO and DLP are implemented together, you can essentially chain wireless stations by using them as repeaters.
Task Group N is still in the mix. TgN's point of focus is to offer better wireless service. It will operate in the frequency range 5.18 Ghz and 5.32 Ghz. The current frequency range that all 802.11a products use. I think the plan is to use the OFDM rates of.11a with 802.11e (QoS). Using MIMO on all stations, with DLP (802.11e) would in fact allow stations to communicate through eachother, instead of the access point. Relaying signals on multiple frequencies through stations would give better coverage, and with DLP essentially cutting all station-2-station traffic in half would free up the medium (their idea of faster?). Either way it is still not going to be around for a while.
I used to feel the same way as an underclassman. You should dig deeper into the education, maybe you can find something that interests you enough to go to class that you are paying for.
I can see it now.

When I entered high school, ahem public high school, there was 1 computer for every other student. We were forced to take simple applications classes and do projects using internet sources routinely. This sort of education made it possible to have a 90+% graduation rate and close to a 70% college attendance rate. Our school also put out alot engineering majors.
I don't mind paying the tax, the problem with education and IT is the lack of knowledge most older teachers have. I personally think the tax gives interested students a better edge on the foreign competition.
Completely right; it is a vendor problem, but only because these products are being marketed to everyone, not just the tech-savvy.
IMO the real problem is accidental bandwith sharing, MSO's are not getting as many subscriptions to broadband, which translates in to less cash.
From the users perspective, the only real threat is malicious owning of an access point.
Where I work we have an internal wlan using WPA-PSK, and an external wlan for vendors with no encryption that is outside of our firewall. No encryption is used for ease of use for our vendors. It seems the only problem we have had is neighboring companie's employees violating thier net access agreements by using our external wlan for thier use. This is not a problem for us, but it lets the employees access restricted websites through other means.
This is not important. If you pull something out of a box, plug it in, and pray to the gods of technology that it works; this is what you get. Any fool knows that default passwords are for faulty individuals.
Well if they all transfer, more power to you, take with salt because I was told the same thing by the AP people, and it is simply not the case. The only thing it helped me with was making my freshman year cake. I had already took three of the classes as AP in highschool, which naturally lead to me slacking off.
They will probably count towards credits, but you may still have to take the freshmen classes.
When I took the AP CS exam back in the day, I got a 5, two years later in college I discovered that it didn't count for any CS requirements, but I could use it towards a free elective. Same went for calculus as well.
Well that 8 credits only cost me about $150, alot better than the $1600 I would pay for them now.
On a side note, who here had the BigInt case study?
What about Discrete Math, and Mathmatical Proof? These are two very important skill sets for a computer scientist. If you want to code or script, little amounts of math are necessary. If you want to prove the efficiency of an algorithm, Hold on to your hat
The reply to your comment is right. Lets say the 7.7 miles/sec for the asteroid hits earth along its orbit(I don't know the validity of this, but giving the benefit of the doubt). Earth is traveling at around 18.2 miles/sec. That makes the distance between them shrink at about 27 miles per second. So it is more like 2 seconds to break the atmosphere and hit earth, but it is more likely not to actually make contact. It would probably just burn the earth for miles. This is assuming that it is morning at ground zero of the impact site, a maximum Interesting Link
Nukes would do nothing!
An asteroid the size of Tautatis traveling at cosmic velocities would puncture the earth. It would take less than a second for it to hit the crust after it entered the atmosphere. Everything withing 150 miles would be burned from the asteroid vaporizing. The blast would follow at almost the speed of light. You would die from the heat or the blast before you would even hear it.
That is just the impact, all sorts of seizmic activity could occur in the time after.
As for nuclear missle launch, the rockets attached to nuclear missles do not have enough power to escape earths atmosphere, and if they did, they are not designed for space. Above all of that it would create all sorts of nasty fallout when the smaller size chunks of the nuclear asteroid fell all over the earth.
By the way, they are practically invisible, and we constantly discover new ones flying by.
