The visionary lies to himself, the liar only to others - Nietzche
Basically US cordless handsets operate at both common Wi-Fi frequencies - 2.4 GHz and 5.8 GHz. But since the FCC approved a new frequency for DECT back in April [2005], the Dua@lphone works very happily as a combined Wi-Fi and a cordless handset. As the INQ described here Hot tub version of Du@lphone imminent.
We've actually got a price, too. Should be around $149. The guys at RTX are obviously very busy and don't appear to have hired a US webmaster yet. Eventually you should be able to buy one of these gismos from www.dualphone.us or www.cordlessdualphone.com.
The company ain't got www.rtx-america.com going yet, either. Can't imagine Santa Clara is short of good html jockeys. ยต
