108mbps wireless

[kof2000]

does it only works with 108g routers or it works with 54g and will it run at 108 or 54mbps?

Not sure what you mean you havent made it very clear. If you have a 108g router and a 54g adapter then it will only receive at 54. Same as if you have a 54g router and a 108g adpater then it will receive at only 54, as always operates at the slowest value.

 

[kof2000]

it is backward compatible.

The 108Mbps routers use the G standard, however each company has their own way of achieving the 108Mbps rated speed. So yes, you can use any other G device and it will run at 54Mbps, but most likely you would need to purchase identical client cards from the same manufacturer to achieve the rated 108Mbps.

Also, though I am not sure if this is true for all brands, you can only get the 108Mbps if all wireless devices on the network are capable of doing so. Should a device that only does 54Mbps come onto the network, then all the other devices would downgrade their speed too. I believe this is what happens with dlink products but not sure about others.

Thats very true, with all those types of products.

Manufacturers can achieve 108Mbps with only 802.11g by using multiple channels to output the data. Cards that are from different manufacturers or aren't capable of those speeds, can only use the traditional 54MBps speeds, and will downgrade the network.

108 Mbps is a feature of wireless adapters and routers based on the Atheros chipset. As long as all the harware uses the Atheros chipset, it should connect at 108 Mbps, though real-world rate will be less than that.

Nope, different companies use different approaches to reach 108Mbps. Some manufacturers may be compatible, but most likely they won't be.

The only actual standard is the 802.11g, which run at 54Mbps. Anything rated above that is not a standard, and is not guaranteed to work with others.

Which was precisely why I used the term "should."

I'm fully aware it isn't a ratified standard, but thanks for the reminder anyway.

very very true, and very worth noting, most cards cant reach the 54Mbps let alone 108. we'll need to wait for 802.11n for better universal bandwidth.

the word "should" implies that the balance of probability is in favour of the event. In this case that is unlikely and a better word would be "may". Omega was just clearing up a little ambiguity in the statement Anyhow this is just semantics.
