What does "Dual-band N Wireless" mean?

by Doctor Who / February 16, 2009 10:15 AM PST

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?

Dual bands means using two different RF frequency bands
by Slackenerny / February 16, 2009 11:19 AM PST

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"
by Steven Haninger / February 17, 2009 9:44 AM PST

but with "a" and "b/g" these came in two 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
by oliver_sam / March 14, 2009 1:51 AM PDT

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

In reply to: question about the 5g

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.

The most beautiful phone ever has one wildly annoying issue

The Samsung Galaxy S8's fast speeds and fantastic curved screen make it a top phone for 2017, but the annoying fingerprint reader could sour your experience.
