[Prism54-users] SMC2802W V2 (prism54 nitro)

[Dave Feller]

There are actually two revisions of Nitro - the first released early
last year is simply a software addition of packet bursting and
protection mechanisms for G solutions - this did two things - it helps G
radios play better when b radios are around (before the release if a b
radio entered the network the whole thing would come down to b speeds
and the whole benefit og G went away) - and by sending more packets
through the air with less dead time in between sped up the whole network
by about 15%...

The new Nitro (NitroXM) adds compression (actually much like WinZip
compression but real time), more packet bursting, concatenation, and a
new feature we call DirectLink that allows client to "associate"
directly with each other bypassing the AP if they need to send data
locally thereby effectively doubling the throughput... We are claiming a
max of 140Mbps throughput  - we have shown 90ish using Chariot TCPIP
client to client. UDP goes even faster... SMC announced XM but have not
seem it on the shelves myself - expect it very soon.

Hi,

I use a SMC 2835W PC card which says it is a nitro card. It gives the=20
same PCI ID as your's, which is the same as other chipsets listed on the

prism54 web site. It works with the prism54 driver (although I do get a=20
few quirks, which may or may not be due to the driver). The firmware=20
file with the windows driver is one of the older ones on the prism54 web

site, so nothing new there for a new chipset. As far as I can tell Nitro

is just a marketing names for their new Windows driver, and not actually

a different chipset at all. They have just added some stuff to the=20
driver to pump up the through, I think.

Regards,
Steve
