Intel Dual Band Wireless AC vs AN. What's the point of AN?
Intel Dual Band Wireless AC vs AN. What's the point of AN?
On the T440s, you have the option for the same price ($30) to choose either the Intel Dual Band Wireless 7260AN or the 7260AC card.
Isn't the AC standard completely backwards compatible with A, B, G, and N? So what's the point of the 7260AN?

Re: Intel Dual Band Wireless AC vs AN. What's the point of A
The AN only uses standard ABGN
The AC uses standard ABGN plus the new AC.
Intel makes even more of a mess:

On the AC cards the 5GHz band is AC only, leaving just the 2.4GHz band for the rest and limiting the speed to anywhere between 150 and 300Mbps, depending on a number of factors. In most scenarios it will be 150Mbps.

Re: Intel Dual Band Wireless AC vs AN. What's the point of A
I suppose you must be mistaken. The Dual Band 7260AC card is specified to be able to do IEEE 802.11 abgn. That means it can do 802.11a and most probably 802.11n in the 5 GHz band too.ajkula66 wrote:On the AC cards the 5GHz band is AC only, leaving just the 2.4GHz band for the rest...
Re: Intel Dual Band Wireless AC vs AN. What's the point of A
From what i understand, and as long as both cards cost the same, there is no point in getting the 7260AN card. The Dual Band 7260AC should be able to do all the 7260AN card can do plus IEEE 802.11ac.cb474 wrote:So what's the point of the 7260AN?

Question:
Has any of you been able to get over 300Mbps using 7260AC on a *non-AC* dual-band router? I haven't.

Re: Intel Dual Band Wireless AC vs AN. What's the point of A
I don't think anyone could hope for getting more than 300 Mbps throughput with an 7260AC card in a non-802.11ac network. The 7260AC card uses a maximum of two spatial streams per direction. With 802.11n technology, each spatial stream can deliver a theoretical maximum of 150 Mbps, but real throughput will probably be much lower.ajkula66 wrote:Question:

Re: Intel Dual Band Wireless AC vs AN. What's the point of A
I'd beg to differ since I've seen 450Mbps with Atheros 9380 and only two antennae more than once.TTY wrote: With 802.11n technology, each spatial stream can deliver a theoretical maximum of 150 Mbps, but real throughput will probably be much lower.

Re: Intel Dual Band Wireless AC vs AN. What's the point of A
The Atheros 9380 uses three spatial streams. I suppose that the card's third connector - the one, to which no antenna is connected - might still work as a transmitter, even if no antenna is connected. That could explain the higher speed.ajkula66 wrote:I'd beg to differ since I've seen 450Mbps with Atheros 9380 and only two antennae more than once.

That sounds like a plausible explanation, or at least a part of the equation.TTY wrote:The Atheros 9380 uses three spatial streams.

I have a build coming up and am intent on testing several cards - including the "non-AC 7260" - as a part of that project.
We'll see what I come back with. Stay tuned...

Re: Intel Dual Band Wireless AC vs AN. What's the point of A
Yes, I understand that the AC card can do everything the AN card can, plus it has AC. I thought I indicated that in the OP.TTY wrote:From what i understand, and as long as both cards cost the same, there is no point in getting the 7260AN card.

I think people have misunderstood my question. My question is, why does Lenovo offer the choice of either the 7260AN or the 7260AC for the same price, on the T440s, if the 7260AC does everything the 7260AN does, plus it has AC? It doesn't make sense.

They need to get rid of surplus/old stock.
And not everybody has or wants AC, because it only works on 5HGz and over a shorter distance than N.

Re: Intel Dual Band Wireless AC vs AN. What's the point of A
Ah, thanks. Seems like it would make more sense to charge a lower price of the AN card, then, otherwise people have no incentive to not just get the AC card. Unless Lenovo is just praying on people's ignorance.RealBlackStuff wrote:They need to get rid of surplus/old stock.
