What does "Dual-band N Wireless" mean?

by Doctor Who - 2/16/09 6:15 PM

I'm looking at having to replace my Netgear router, which I've had for ~4 years. I'm looking at what's out there and have seen a couple of routers by Netgear and Linksys that are listed as "Dual-band N Wireless Routers".

So, what does that mean?

For now, for today I only entertain N when I can get all the gear from one maker.

If you want to read what fun you can have with Draft N, read http://forums.cnet.com/5208-7585_102-0.html?forumID=19&threadID=329526&messageID=2974763&tag=forums06;forum-threads

It took awhile but the end was typical.

Dual bands means using two different RF frequency bands

by Slackenerny - 2/16/09 7:19 PM

In Reply to: What does "Dual-band N Wireless" mean? by Doctor Who

You can use two different RF frequency bands in 802.11N: 2.4GHz or 5GHz. The first Wi-fi specs, 802.11a, used 5GHz and if you only need short range it performs GREAT. The trouble with 5GHz is its range is quite pathetic. The subsequent 802.11b and 802.11G use the 2.4GHz, which offers better range but also its fair share of drawbacks: it only offers 3 independent channels effectively and more importantly the 2.4GHz is over-crowded (cordless phones, microwave ovens and bluetooth all operate on that spectrum so can easily result in interference). 802.11N allows you to use the 5GHz whenever it's possible, otherwise it'll switch to the 2.4GHz band.

Not sure about dual band with "g" or "n"

but with "a" and "b/g" these came in two flavors...one being a dual radio which could operate on both frequencies at once while dual band rigs just switched from one to the other as required.

question about the 5g

So is it better to have a router with the 5g option, if it is used primarily wired?
Will it be faster than a unit operating at 2.4?

N system

You would need N capability in the systems to make it matter, N antenna in L/T N cards (adapters) in destops (for wireless) more hardware and more money.
