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 solutions direct the signal "more efficiently" towards specific targets (focusing beam in certain direction, monitoring interference, "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?). In some of these cases, the receive antennas are just an omni antenna. (802.11 is not a timing based protocol, so I don't see how beamforming benefits on the receive side will ever happen) So is the best that we can hope for with beam forming is faster download but the same old upload? How will the standard (once baked in more vendor gear) do things differently? -------------------------------------------------------------------------------- WISPA Wants You!
