Wireless N anyone

Do current antennas support the new wireless N standard? Can the full
throughput of N be achieved through say a parabolic grid dish?

Fraid you were lied to big time.. There are *NO* wireless N standards yet
(won't be voted on and adopted until next year at the earliest), so there
can't possibly be any 'new N standard'..... The generic (not the
manufacturer specific ones that may or may not work when standards ARE
adopted), use the same frequency range as B and G, and should work fine with
anything that works with B or G now....

I havn't been lied to lol. What I should have said is the up and coming
new N standard. I know its isn't relesaed yet and probably wont be for
quite a while. Just considering the worthwhileness of buying current
gear, IF the upcoming N standard isn't fully compatible.

But cheers for your reply

The gear itself is what may be iffy, cause each manufacturer has their own
way of doing things, but your original q was about anennas, and no matter
what ultimately wins, anything that uses 2.4 GHZ b/g stuff should also work
with the new stuff also

A fact is, you only can get a antenna for 2.4GHz or 5GHz, i guess...
5GHz is not much used, by Microwave ovens or wireless video ?

What standards? 802.11n is not predicted to be approved until about
Sept 2008.
<http://grouper.ieee.org/groups/802/11/Reports/802.11_Timelines.htm>
What we have this week is Pre-N Version 2 Draft Specification.

As for whether a current antenna can "support" the specification when
passed, I don't know. The printed version of the draft specification
weighs about 5kg and is growing every day. By 2008, the spec just
might weigh enough to collapse the antenna. However, I wouldn't worry
about it as heavy duty antennas will surely be available.

A better question would be whether the full thruput can ever be
achieved or demonstrated. Tests of Pre-N hardware on SmallNetBuilder
have been fairly disappointing. Also see:

If it's long range MIMO, you're going to have a big problem. With the
beam forming flavor of MIMO, you can't screw with the antenna because
the antenna is an integral part of the beam forming system. In other
words, you can't substitute antennas, period.

With the Airgo flavor, the system relies on having multipath. The
different antennas all must have slightly different end to end path
lengths. You would need 3ea dish antennas, not one. They would also
need to be slightly staggered and be very carefully positioned. I'm
not sure about the timing, but as Pre-N v2 is NOT designed for long
range, you might slam into some kind of timing limitation. Note that
most MIMO infested products do NOT have removeable antennas.

Now that I've had my fun....
1. What are you trying to accomplish?
2. What do you have to work with?

Cheers peter pretty much what i think
