AT&T Expands Wi-Fi Hotzones Amid Heavy iPhone Traffic

Major markets struggling to meet large wireless data demands are about to receive a boost from AT&T Mobility. The company announced that it will be expanding its pilot program to provide free Wi-Fi access to subscribers in strategic locations around the country.

The point of all this is to alleviate data traffic on the AT&T 3G network. Since the iPhone's introduction in 2007, AT&T has been slammed by app downloads, web browsing, and other high bandwidth uses on its network. In a plus for users, data transferred over a Wi-Fi connection does not use data plan bandwidth.

What if you could just plug your iPhone directly into a router with a USB cable and share the 3G data connection with every Wi-Fi device within 200 feet? Now you can, with Nexaira's Business Class 2 tethering-ready router. The router is compatible with the iPhone 4, iPhone 3GS and iPhone 3G.

Of course, if your iPhone is not jailbroken, you'll need to enable official tethering with your cellular carrier. AT&T offers iPhone owners tethering for $20 per month. With tethering, simply plug in the Nexaira BC2 router, connect the iPhone via the rear USB port and you're all set. Anywhere with power and a 3G signal becomes a Wi-Fi hotspot.

Two Great iPhone Jailbreak Apps for Wi-Fi

Looking for more ways to improve your jailbroken iPhone? Many applications are available that expand the features and functions of your iPhone beyond what Apple allows. Tethering is one such function that makes it possible to use your 3G data connection to create a Wi-Fi hotspot for other devices. AT&T has finally made an official tethering solution available, but many customers don't want to pay the extra expense.

Can I use Wi-Fi with the iPhone in airplane mode?

Yes, it's possible to use Wi-Fi with the cellular radio off. To enter airplane mode:

Touch Settings -> Airplane Mode ON

This turns off all radio activity including cellular antennas and Wi-Fi. Now while staying in airplane mode you can turn on Wi-Fi only.

Touch Settings -> Wi-Fi -> Wi-Fi ON

Your iPhone will now use the Wi-Fi connection while keeping the EDGE and 3G radio off.
