WiMax Formed To Promote 802.16 Standard

Posted by timothy on from the is-standard-the-right-word dept.

The Original Yama writes "Intel, Nokia, Proxim, and a bunch of other companies have launched WiMax, a non-profit group founded to certify and promote the IEEE 802.16 wireless networking standard. What's interesting about this standard is that it allows "up to 31 miles of linear service area range and allows users connectivity without a direct line of sight to a base station," all at a shared speed of 70Mbps. This simultaneously blows away 3G mobile and 802.11 technologies."

  1. Not a competitor to 802.11 or 3G by Wesley+Felter · · Score: 5, Informative

    This simultaneously blows away 3G mobile and 802.11 technologies.

    802.16 is designed for fixed outdoor operation and the antennas are much too big to fit in a PCMCIA card, so it won't replace 802.11.

    802.16 clients can't move around, so it can't replace 3G.

  2. This competes more with free space optics by bdhein · · Score: 5, Informative

    From the article, this technology is meant to link 802.11 hotspots, not as a replacement to 802.11.

    Free space optics is another interesting field that will give you upwards of 1Gb/s over 2km. More info on free space optics.

    All of these technologies are emerging to try to link the last mile to the high speed backbone as the cost of fiber is prohibitive (~$325/m) and the majority of the US doesn't live on top of a fiber backbone.

    For those whom are not aware of this technology, I gladly provide the following linkage:

  4. A bit on this technology by stj · · Score: 5, Informative
    The technology itself is new and barely IEEE approved. In fact there are three versions of the standard to date (keywords made up):

    regular - for 10-55GHz frequencies and that one actually gives even up to 134Mbps. Now, because it uses range-dependent modulation techniques, you'll not have 70Mbps @ 30 miles. At 30 miles you might have about 20Mbps

    somewhat limited - for 2-11GHz which is unlikely to be implemented because it runs into almost all possible licensed frequency bands

    unlicensed - for 5 GHz unlicensed band - exactly the same as 802.11b
    Now, in any case, this is a fixed wireless network - that is stations are not mobile. So, it's NOT a competition for any mobile standards. All of that is very questionable at the moment because it will require quite a large licensed band and unlike UWB, it will transmit at measureable powers. I don't think Nokia would do anything to kill UMTS and 3G.
    There are some ISPs using it: installation cost in one I know is around $700 and monthly cost is $40 for wireless T1.
