It would appear as though the 802.11n new multi-streaming modulation technique extends the range not the frequency. So as you already knew you are right about that but the IEEE extends the range.

You might want read up on some of this stuff. The question you should be ask is why switch to wireless N not why should the EVO support this technology.

Also it would be cool if we could keep this in a normal discussion and not a FLAME ATHON...

We're not debating the capabilities of multi-steaming (MIMO)... Here is what you said verbatim...

For example N uses higher frequencies (5ghz vs 2.4ghz) that have extended range and penetrate walls better.

The higher frequency does not: 1. Extend the range. 2. Penetrate walls better.

There's also the fact that wireless N can run on 2.4GHz in place of 5GHz, which is opposite of what you said.

I will also add that you should use the 2.4GHz option if you are looking for extended range as the lower frequencies will penetrate walls better, and the additional speed from the 5GHz frequency is not necessary in this case. In contrast, however, chances are good if you have any devices running on N other than the phone, you will probably have 5GHz enabled for the added speed, which contrary to what the Wikipedia article says, WILL drop your operating range down over 2.4GHz (by half in theory, which increases exponentially as you include obstacles like walls).

The ONLY benefit for wireless N, is added range, and only if you're choosing to use 2.4GHz over 5GHz. There are a FEW routers out there that can simultaneously transmit over 2.4GHz and 5GHz, such as the D-Link DIR-825, however they're expensive at over $120, and unnecessary for 95% of users.

To top it all off, the connection will only be as good as the receiver / transmitter you're using in conjunction with the router... Even if you can receive a WiFi signal with the Evo from a mile away, being able to transmit what you want to do (such as query a webpage) is limited by the range of the handset, not the router.

If you want to question my knowledge on the subject any more please take it to PM. Throwing half-truth Wikipedia article links out in an attempt to make yourself look more intelligent on the matter isn't helping your case any.

How do i flash the zip for the wireless n into the phone? Thanks

PS Im rooted using toasts method, but not full root yet.

[JaredC01]

Put the zip file onto your SD card, turn the phone off, hold down the volume down button, turn the phone on (without releasing the volume down button), once loaded up, flash from SD card, highlight the file, tap the power button to select.

Not to mention 5ghz actually penetrates walls worse. My Evo using wireless G is getting about the same range as my ipad on my N network. My iPad also does better on my 2.4ghz N network vs. my 5ghz N network. I'm using a Linksys WRT610N running DD-WRT firmware. Where N is going to have the advantage is in the MIMO. This is going to let it run multiple connections simultaneously. Of course if the EVO and or your router don't have multiple antennas on the wifi you're not getting this advantage either, and this may be the reason HTC didn't enable N.

I guess that's not good enough for you I will PM a formal statement. Don't switch your device to wireless n I could careless. Tell everyone else not too either I hope they listen to you since you are the expert. Anything else we shouldn't use?

Now you're trying to twist my words, stop grasping for straws. I said there's no point in using N on the Evo, and I still stand by that. The extra speed is of no use on the mobile device, and as put in my last post unless you're using 2.4GHz N, there's not a large range boost, especially through walls, when using 5GHz.

I realize you said I was right about the frequency, but you also said I "might want read up on some of this stuff" in regards to the capabilities of WiFi itself. I reiterated the issue on frequency, quoting what I was referring to in the first place, and I gave accurate information on wireless N based on my knowledge of it (not a Wikipedia article that still needs proper information) and why I think it's a waste of time overall.

Wikipedia won't ever be a 100% accurate source of information due to the fact that anyone can create a Wiki page, and anyone can add to it. You can see that a lot of the information on the Wiki pages has the caption: [citation needed] or [clarification needed], meaning there isn't information to back the claims on the page. That would also be why it lists the range for 5GHz N as the same as 2.4GHz N, among other things.

WTF do some of you people even care for?! Why so serious? Why so negative?

If you don't see the benefit... don't use it. But some of us actually HAVE Wireless-N either at home or at our businesses, and we'd like to friggen use it if we can!

I bought a device that happens to be capable of it, so by God I'm going to use it if I can!

I'm a system administrator for a hospital. I have Wireless-N there, my home, and at the corporate office, with a gigabit fiber connection between the two offices (though sadly not my home). You better believe I wanna take advantage of as much throughput as I can when I can!

Don't be coming on these forums bad-mouthing those of us who want to actually USE our phones!

Thank you sir Jared

GoodThings2Life, PLEASE don't misinterpret what I say as a negative towards the phone or anyone else in the forum. I asked a legitimate question: "Am I the only one that doesn't really see the point in this?"

If you want to enable it, I'm not one to object... I personally don't see any benefit. The extra battery usage associated with using wireless N, along with the fact that there is nothing that I would do with the phone that could even utilize N speeds, makes me question the worth of doing it.

With my legitimate question, zone23 chimed in with incorrect information about why wireless N is better than, and why it should be used over wireless B or G. I corrected him on the information, including an example as to why it's the case, to which he comes back with a Wikipedia article saying I need to read up on my information (arrogance). I then correct him again, to which he calls me a 'prick' and starts getting defensive.

To zone23, IEEE 802.11n is the official label for WiFi N, just like IEEE 1394 is the official label for Firewire. What I am saying is that unless you're using 2.4GHz wireless N, which is going to be the minority of people, there is no benefit to using wireless N over wireless G, since the Evo can't make use of the added bandwidth N offers, and there is very little range difference between the two. My original post correcting your information was not meant to be arrogant in any way, just corrective. You took it defensively and lashed back at me, which was not the intention. I've got no problem letting the issue go.

Edit: HTC_nut, you're welcome!

I appreciate the clarification... just seemed like the choice of words and verbosity was making you a bit condescending, so I apologize if my response was a bit harsh.

Anyway to the heart of the matter, yes, it matters (at least to me)... I have a VoIP phone system at work (Cisco CallManager). On WinMo, I previously ran the Cisco Mobile Communicator app to provision my phone with my desk extension. No Cisco app for Android yet, but there are SIP-capable apps that let me do it anyway. Very nice. Anyway, from a network traffic standpoint, internally I DO have a network capable of reaching said performance points, so it's a nice boost... in other words, it's not just about Internet connectivity.

Also, FYI about using more battery... you're technically right in theory, although in practice, any time you can improve overall signal quality to get a more stable connection, it does reduce battery usage, not increase it... same thing happens when you have low cell signal versus high. The point is this... I actually consistently had an extra bar of signal today so it wasn't trying to roam between access points so often, and when I came home from work I was 7% higher in battery life than less usage yesterday.

Update: PS-- I'm paying the same $10/month for "Premium Data" as everyone else, and you better believe I want to take advantage of every last option I possibly can if the hardware supports it. I'm also rooted and using the wifi tethering this way.
