IEEE Standards Board Passes 802.16a

papason writes "Welcome the birth of the IEEE's first wireless MAN standard for broadband wireless access in bands ranging from 2GHz to 11GHz. Yes, the same group that brought you 802.11b has brought you a real broadband wireless access standard. See wirelessman.org for more details."

No, here it is: http://www.commsdesign.com/story/OEG20030130S0055 Maybe I'll click HTML instead of Plain old text next time.

Re:compared to 802.11g

This isn't 802.11a, this is 802.16a. 802.11 standards are for wireless LANs, 802.16 standards are for wireless MANs. And just in case you don't know, a LAN is a "local area network," and a MAN is a "metro area network."

I doubt Apple will use this standard much, but I imagine your phone company and/or cable company will bitch to high heaven to keep this out of your home.

The Speed

[Arcticfox24]

According to this site, the speed of "IEEE 801.16.1 is intended to support individual channel data rates of from 2M to 155M bit/sec."

Re:What about Apple's 802 standard

802.nnx are by definition standards (IEEE standards to be exact) and therefore Apple could not come out with their own. Apple is AFAIK going to use 802.11g which occupies the same spectrum as 802.11b (2.4Ghz) but uses a much more advanced and efficient encoding scheme OFDM vs DSSS so it has a max line speed of 54Mbps vs 11Mbps for 802.11b. The encoding is the same used for 802.11a uses in the 5Ghz range so other than needing two antenna and phy systems a lot of the core logic can be shared, that is why most manufacturers are targeting tri-mode 802.11a/b/g devices for the second half of this year. It will allow universal wireless connectivity no matter what the AP is speaking.

Re:compared to 802.11g

All major manufacturers that I am aware of have a tri-band 802.11a/b/g chip/system in the works. Because 802.11a and 802.11g both use the same encoding scheme a lot of the core logic can be shared between the two, now add backward logic for 802.11b and you have a complete package. You need two phys and two antenna systems (though they will usually use the same antenna substrate for space) and thats about it. As for security that too is in the works, I believe the 802.11x comitee is working on WEP2. Besides there are a variety of solutions on the market that are already secure. For instance Cisco uses dynamic user authentication through RADIUS to dynamically give out keys to each user and the keys change on a user specified interval (make the interval small enough and cracking the keys goes back to cracking a 128bit key, most difficult), this is an oversimplification of the system but enough to get the point across.
