Re: [LUG] Is 802.11n actually ratified now?

[Dan Lewis <danlewis.ltd@xxxxxxxxx>]

Yes it runs at 5ghz and 2.4Ghz which if you are in a secluded area gives you the ability to throughput hightraffic connections - ie gaming pc, connection nas, etc on the 5ghz frequancy and then everything else on the lower frequancy. be warned the lower the frequancy the better it will penetrate materials ie walls etc.

I dont believe that all wireless n devices are dual band, they can be either or and both. truthfully what i have found is that having a mimo card in my pc helped maintain signal quality more then anything else. yes the reach was a little better - but not what they claim. 

I have a ibm r50e which is truly a fantastic laptop and i use an old pcmcia dlink wireless g card and get signals from the other apartment building across the road!!! and my main pc with the wireless n card doesnt do any better - about on par. i just never lose my signal with the primary pc.

hope it helps

i think it comes down to WHY? until you can answer this you should not have wireless n

What are people finding in the real world (in this case a rural/suburban
home situation with 4 other users in sight)?
"It also has a greater effective distance."

Again what sort of difference does this make?

I.E. is it really worth the effort of upgrading the laptops - the bridge
I really should replace given that it has partly malfunctioned anyway...
I suppose...
 

I gather it runs at the less crowded 5GHz frequency and also makes allowances for multiple networks.  Not having got any N equipment yet (apart from my BT Home Hub 2 but no compatible Wireless N adaptors) I'm not sure how well it runs.  I guess partly it could depend on what is connected to it.  Reading the spec on my BT Home Hub 2, the switch in it was only 100Mbit, so in theory anything going over that is limited to about 100Mbit.

Maybe if you have a lot of wifi networks in your area it might make a difference.  I must have about 20 wireless networks in my area.
