That's the way cell phone networks maintain your connection, of course. It's also part of the latest wireless networking technology specifications. Without researching it I'm going to guess it's in the 3rd part of the WiMax spec just adopted. 802.11n, mebbe? Whatever. This step is about to happen and it will turn our portable devices into mobile devices. All we have to do is wait because it is definitely happening. We can be glad that Nokia, a cell phone company, is the 770's manufacturer because as the 770 gains VOIP (by June, I believe) the distinction between a portable device and a mobile one becomes critical.

There isn't really any disagreement about the standards coming in the next generation of wireless networking performance and devices. There is, however, a big disagreement in the standards in the next generation of ultra wide band. Freescale (formerly known as Motorola Semiconductor) on one side and the WiMedia group on the other. The market will decide that one.
