    802.11b Standards.

    Where does the 802.11 standard hold? I know there are talks to improve the standard, but has anything changed?

    pretty good info on this site - although for more indepth surveys, you need to pay for it. Looks like the 802.11g standard is moving along into production environments.

    there is also some info on the ieee website for 802.11.

    there are actually three WLAN standards 802.11 a/b/g This is my understanding and I might be wrong on this but 802.11b is standard for 11Mbps WLAN 802.11a is standard for upto 54Mbps WLAN there are differences between them and they are not compatible. There are pluses and minus to both. there is a newly ratified standard 802.11g which is compatible with both 802.11a and 802.11b. I know there is more informaiton out there and Network World p[ublished and artivcle a month or so ago on the standard and I only skimmed it and this is what I gleaned....

    that's funny I was going to link to the site that bombay did nice...!

    Paldie > as a correction to your post, as far as I know, 802.11g is compatible with 802.11b (they both work on the same frequency), but not 802.11a which runs at a higher frequency. 802.11a runs at 5 GHz, with a maximum transfer rate of 54 Mbps, while 802.11b and 802.11g run at 2.4 GHz, with transfer rates of 11 Mbps and 20+ Mbps, respectively. Since 802.11g is backwards compatible with 802.11b, many businesses are currently being attracted to 802.11b, because they know that they will be able to upgrade the access points to 802.11g at a later date, while not having to upgrade all of the cards, though, they will still only be able to transfer at a rate of 11 Mbps.

    I know of another wireless device for WAN that can do almost a gig full duplex on the 5ghz spectrum (western multiplex) although they just got bought, or they bought proxim. Kinda a cool product - i had a customer get 45mbps full dup for his two facilities about a mile apart over a major freeway (about 30K). Try getting a telco to provide that in under 6 mos (not to mention the ROI for a t1 was about $4500 at that time.

    It could very well be a 802.11a device with a unidirectionnal antenna..
