801.11 a b and now g?

[Hoolio]

I have been out of the loop for a while now:

Could someone explain the difference between
802.11a and 802.11g?

I know 802.11b is the original standard and 802.11a is 54mb/s @ 5Ghz but what is 802.11g?

802.11g is a new standard that I don't think is finalized and last I read isn't due till mid 03. Its 2.4ghz like 802.11b but it supports 20+Mbps. You may be thinking... why not go with 802.11a then and get the bandwidth. Well the 802.11g will have better power consumption and go longer distances than 11a. 11b already has these advantages over lla. Price is also supposed to be in line with current llb components. And best of all the 11g devices can talk to 11b devices.

It may say I'm a NOOB but I've been hiding in the shadows @ THG since 97.

I thought the whole reason for 802.11a was made so the wireless networking band was the only one at the 5Ghz frequency. Does this mean 802.11a has been abandoned or that 802.11g is a stop gap between 802.11b and 802.11a?

I don't have any official word on why. But I do know the 5ghz doesn't get the same range and requires more power. Ultimately I don't think 11a or a child of it will be the solution. They are working on new types of wireless technology to get amazing speeds and connectivity. (Some waiting on FCC). For current wireless technologies look to see that security and features are enhanced before speed.

Well I read the ZDnet link above and it said the way 802.11a is not supported in most of europe. I think as 802.11a products are availible in the UK then the UK is not the problem, but 802.11h sounds good, adjusting the power of the transmitters so they are using the minimum amount of power to talk to the node farthest away. That is good and it will be 5Ghz
