AT&T using 802.21 for handoff of iPhones to Wi-Fi?

updated 04:25 pm EDT, Thu June 18, 2009

AT&T iPhone handoffs

AT&T may be adapting a new protocol to relieve pressure on its 3G network, reports say. The 802.21 protocol may be responsible for the new prompt-free process of automatically transitioning an iPhone from 3G to one of AT&T's Wi-Fi hotspots. The technology is designed to switch to and from cellular, Wi-Fi, Bluetooth, 802.11 and 802.16 networks using handover algorithms.

Whether or not it uses 802.21, the process is being called "auto-authentication" by AT&T and eliminates the previous two-step process of switching between networks. The feature becomes available once the iPhone 3.0 firmware is downloaded. The upgrade was released through iTunes on Wednesday.

    Not sure..

    I have a WPA-encrypted wifi network at work. Every day I come into work, turn on my iPhone, launch Safari and within seconds I'm connected. When I leave the office I'm back on 3G. So what is this auto-authentication doing for me that I didn't have before?

    Re: Not sure

    You're reading it backwards. Its turn on your phone and open safari outside on 3G, then walk into the office. This should then auto-switch over to wifi and off the data network. That's how I read it.
