iPhone 4 is 2.4Ghz only?

The channels are important. But whatever....

I never said the weren't😀

My wifi speeds are great... Why is this a problem? What are you guys trying to do with your phones that makes this a subject of argument?

I almost cried when I found out. Microsoft did the same thing with the new Xbox. It has n built-in but it only supports 2.4, while the external adapter supports 5. I hate it.

Aww, I was going to buy a new xbox for my bedroom to stream nextflix, and my media collection, my router is crap on 2.4, too many other devices operate on that frequency in my house.

Here's what I'll do...

Since I'm living in a house with 5 other people, (I guess you guys overseas call them "flatmates" 😎) I'll probably set up one network with 5GHz for me, and a 2.4GHz. My new router has a choice of auto 20MHz or 40MHz, my old one could only pick one or the other.

What, is critizing the iPhone for something other than it's antenna blasphemy here? Yes I get almost all of my bandwidth over a 2.4GHz network, I'm just stating the principle that it doesn't support 5GHz.

I would prefer to have one network, like I said I am living with 5 other people, and our home is bookended by two apartment buildings. Some serious congestion going on.

Adding 5Ghz would mean adding another antenna. The way things are designed right now, there's no room.

What about in this space here:

5.8 has less range than 2.4. Simple physics. 5.8 may be the future, but it requires much more power than 2.4. Performance gains are very slight because the ISP is the bottleneck, not the frequency. Until the connection you get from your ISP gets faster, 5.8 vs 2.4 offers little to no performance gain.

These types of systems are not for regular internet access. these are citywide networks for the city employees to connect to. An ISP is not the main use of this system. in which case while officer A is sitting in the walmart parking lot he can be Uploading his on board video to the video server at the police station. all with out having to run miles of cable to connect the AP's. this scenario there is no bottle neck.

brb having a useless dual-band router. What the heck was the reason for this?

because they can and come next version, then that one will support the 5GHz band and if you want it, then you gotta buy it. Simple.

Also,

>mfw you fail to realize that

Ummm the 802.11n standard supports 5.8, the hardware AP or router, does not HAVE to support it. savvy? Besides read up my friend the 5.8 does not have have the performance increase the 2.4 does.

I think you are the one that needs to read up, my friend. 802.11an radios operate in the spectrum between 5.150 and 5.850 Ghz (subject to local rulings, of course). That's written in the standard. In fact in several locations in Europe, including where I live in the UK, 5.8Ghz or Band C as it's known is set aside for Point to Point connectivity (not WLAN). However, that still leaves us with a LOT more channels to play with in 5Ghz, in Europe at least. And this is significant.

While what you are saying about consumer devices primarily being deployed at 2.4Ghz is reasonable, this is certainly not the case in the enterprise environment. Given that we only have space for 3 non-overlapping 20Mhz channels in the 2.4Ghz ISM band, this means that if you want to deploy a free roaming network (ie with more than one AP) and achieve the full 270/ 300Mbps bandwidth that 802.11n is currently capable then you'll need to go to 5Ghz (unless you're using a wireless vendor who has developed a single channel architecture). This is because an AP cannot operate with a 40Mhz channel if it's neighbour is on an overlapping channel. CSMA/CA.


In a very real way, 5Ghz has become the enterprise band in Europe. Maybe the iPhone isn't an enterprise phone, I don't know, but given the recent proliferation on the app store of mobile convergence apps from the likes of Comdasys and Agito, I'm surprised that more hasn't been made of this. Of course, a decent enterprise Access Point is still dual-band so enterprise iPhone users can be steered back to 2.4Ghz, so it's probably not that big a deal.

When I read the title, I thought you were talking about the processor.

I thought I had missed something.😀
