As Mike points out, beamforming is an optional part of the 802.11n
standard and there is at least some silicon support for this option
emerging (more on that in a moment). The confusion arises because there
are several different things which are legitimately called beamforming.
The simplest
A good primer on 802.11n. Beamfroring starts at page 6.

In the IEEE 802.11n draft standard, beamforming is adopted as an
optional feature to improve signal reception and simplify receiver design.
Beamforming is available in 802.11N, though I don't know of any products
using that
I see lots of discussion about the new 802.11n standard supporting
beam forming, and I'm trying to wade through the chipset ones (e.g.
Ruckus, Extricom, Meru, etc) and other solutions that claim to be more
standards based.
From what I gather from the marketing literature, the various vendor
Rogelio,
Please don't take this the wrong way. You are trying to understand a
very complex 'patented' technology via a very simplistic understanding.
Beam forming is a very complex (lots of analytical analysis done on a
real time basis) technology, there are a number of Masters PHD
interference nulling, etc), but that seems to have limited
effectiveness when it comes to receiving transmitted packets from the
client end (resulting in slow uplink?).
Multi-antenna systems like the ones doing beamforming can provide MRC
(Maximal-Ratio Combining), which does improve the
This reminds me of another question I have: Why dont I
get synchronous speeds? On a rare occasion, I do, but not normally. LOL,
once in a while, I get better uploads than downloads and cant explain that
either!
