Now that the iPhone 5 can connect to a Dual-Band 802.11n network, I went out and bought a new AirPort Express that supports broadcasting at both 2.4GHz and 5GHz. I tested out connecting my iPhone 5 individually to the 2.4GHz network and the 5GHz network I created, and 5GHz seems much faster.
The question is... how do I connect the "Dual-Band" way the iPhone 5 "Features" page talks about? Does the AirPort Express support connecting to both frequencies at the same time? I'm fine with connecting to the 5GHz network because it's still plenty fast, but how do I connect the "Dual-Band" way?
Hi, I'm sure that the iPhone and the Airport Express automatically connect to each other by dual band as standard. There is no setting to change to put the airport on dual band. All dual band does is increase the bandwidth of the signal. Also the 2.4GHz and 5GHz are both separate therefore you can only use one or the other.
"Dual-Band" simply means that the device supports the 2.4Ghz and 5Ghz bands.
It does not mean the device will connect or should connect to both bands simultaneously.
The device connects to one or the other... whichever is available.
There is nothing to change, nothing to configure.
Thanks Diesel, that's what I think I'm finding out by digging a little deeper. I read a little more on the AirPort Extreme page about what "dual-band" means and it's worded a little more clearly on that page.
Here's what it says on that page:
Some Wi-Fi devices use the 2.4GHz wireless band, including iPhone, iPod touch, and devices using 802.11b/g. Other devices can use either 2.4GHz or the higher-speed 5GHz band, such as the latest 802.11n-based Mac computers, iPad, and Apple TV. Instead of choosing one of the bands, AirPort Extreme operates simultaneously on both bands, and your multiband devices automatically use the best available band. This means all your Wi-Fi devices get the fastest possible wireless performance and the best possible range. In addition, AirPort Extreme reduces the possibility of interference from appliances and cordless phones that use the 2.4GHz band.
Makes sense that the iPhone 5 would just automatically would choose the 5GHz band, just like my MacBook Air does.
